Learning and teaching notes: 

The purpose of this exercise is to encourage students to think in a socio-technical perspective of delivering extreme low carbon housing (e.g. Passivhaus), in order to support the occupants in adapting to new technologies and low-carbon lifestyle, shifting the paradigm from building isolated energy efficient homes to forming low-carbon communities.

Terminology: 

Before beginning the activity, teachers and learners will want to become familiar with the following concepts. 

 

Activity overview:  

Students will role-play the post occupancy stage of inhabiting a Passivhaus home by playing different characters with different priorities (and personalities). Students will need to learn what new technologies and features are included in Passivhaus and what difficulties/problems the residents might encounter, and at the same time familiarise themselves with contemporary research on energy behaviour, performance gap, rebound effect, as well as broader issues in decarbonisation transition such as social justice and low carbon community building. Through two community meetings, the community manager needs to resolve the residents’ issues, support the residents in learning and adapting their behaviours, and devising an engagement plan to allow the residents to form a self-governed low-carbon community. 

 

Step one: Preparation prior to class: 

Provide a list of reading materials on ‘performance gap’, ‘rebound effect’, ‘adaptive comfort’, energy behaviour, usability and control literature, as well as on Passivhaus and examples of low-carbon features and technologies involved to get a sense of what difficulties residents might encounter.  

To prepare for the role-play activity, assign students in advance to take on different roles (randomly or purposefully), or let them self-assign based on their interests. They should try to get a sense of their character’s values, lifestyle, priorities, abilities. Where no information is available, students can imagine the experiences and perspectives of the residents. Students assigned to be community managers or building associations will prepare for the role-play by learning about the Passivhaus system and prepare ways to support occupants’ learning and behaviour adaptation. The goal is to come up with an engagement plan, facilitate the residents to form their own community knowledge base and peer support. (Considering 1. Who are you engaging (types of residents and their characteristics); 2. How are you engaging (level of engagement, types of communication; 3. When are you engaging (frequency of engagement) 

 

Step two: In class, starting by giving prompts for discussions: 

Below are several prompts for discussion questions and activities that can be used. Each prompt could take up as little or as much time as the educator wishes, depending on where they want the focus of the discussion to be. 

 

  1. Discuss what support the residents might need in post occupancy stage? Who should provide (/pay for) the support? For how long? Any examples or best practice that they might know? Does support needs to be tailored to specific groups of people? (see extra prompts at the end for potential difficulties)
  2. Discuss what the risks are involved in residents not being sufficiently supported to adapt their behaviour when living in a low-carbon house or Passivhaus? (reflect on literature)
  3. Discuss what are the barriers to domestic behaviour change? What are the barriers to support the residents in changing behaviour and to build low-carbon community? 

 

Step three: Class 1 Role Play  

Prior to the Role Play, consider the following prompts: 

Consider the variety of residents and scenarios:

Their varying demographics, physical and mental abilities, lifestyle and priorities. The following characters are examples. Students can make up their own characters. Students can choose scenarios of  

1) social housing or; 

2) private owner-occupier  

Social housing tenants will likely have a more stretched budget, higher unemployment rate and a bigger proportion of disabled or inactive population. They will have different priorities, knowledge and occupancy patterns than private owner-occupier, and will be further disadvantaged during decarbonisation transition ​(Zhao, 2023). ​They will need different strategies and motivations to be engaged. The characters of residents could be chosen from a variety of sources (e.g. RIBA Brief generator), or based on students’ own experiences. Each character needs to introduce themselves in a succinct manner. 

 

Other stakeholders involved include: 

They are role-specific characters that don’t necessarily need a backstory. They are there to listen, take notes, give advice and come up with an engagement plan. 

 

Consider the post occupancy in different stages: 

  1. Prior to move-in 
  2. Move-in day 
  3. The initial month 
  4. Change of season  
  5. Quarterly energy audit meeting 

 

Consider the difficulties the residents might encounter: 

 

Consider the different engagement levels of the residents: 

 

The role-play consists of two community meetings over two classes. The first meeting is held at two weeks after move-in date. The second meeting at 6 months of occupancy. The meeting should include a variety of residents on one side, and the ‘chair’ of the meeting on the other. (Consider the accessibility and inclusivity of the meetings as when and where those will be held). In the first meeting, residents will get to know each other, ask questions about house-related problems occurred in the first two weeks, voice concerns. Community managers/council members will chair the meeting, take notes and make plans for support. The teacher should act as a moderator to guide students through the session. First the teacher will briefly highlight the issue up for discussion, then pass it to the ‘chair’ of the meeting. The ‘chair’ of the meeting will open the meeting with the purpose of the meeting – to support the residents and facilitate a self-governed low carbon community. They then ask the residents to feedback on their experience and difficulties. At the end of the first meeting, the group of students will need to co-design an engagement plan, including setting agendas for the second meeting in a 6-month interval (but in reality will happen in the second class) and share the plan with the residents and the class. The teacher and class will comment on the plan. The group will revise the plan after class so it’s ready for the second meeting. 

 

Step four: Homework tasks: Revising the plan 

The students will use the time before the second class to revise the plan and prepare for challenges, problems occurred over the 6-months period. 

Optional wild cards could be used as unpredictable events occur between the first and second meeting. Such events include: 

 

Step five: Class 2 Role play 

The second meeting in the second class will either be chaired by community managers/council members, or be chaired by a few residents, monitored by community managers/council members. The second meeting begins the same way. The students playing residents should research/imagine problems occurred during the 6 months period (refer to literature), and what elements of the engagement plan devised at the end of the first meeting worked and what hasn’t worked. The ‘chair’ of the meeting will take notes, ask questions or try to steer the conversations. At the end of the second meeting, the ‘chair’ of the meeting will reflect on the support and engagement plan, revise it and make a longer-term plan for the community to self-govern and grow. At the end of this class, the whole class could then engage in a discussion about the outcome of the meetings. Teachers could focus on an analysis of how the process went, a discussion about broader themes of social justice, community building, comfort, lifestyle and value system. Challenge students to consider their personal biases and position at the outset and reflect on those positions and biases at the end of the meeting.

Role-play instructions: 

  1. Each student is assigned a role a week before the discussion.
  2. Students assigned to the role of Eva Walker serve as the moderator and lead the conversation based on the script below.
  3. The script provided below is there to guide the discussion, but you should leave room for the conversation to flow naturally and allow everyone to contribute.

One way to ensure students are prepared for the discussion is to assign a few questions from the script as a pre-discussion assignment (short answers). Similarly, to ensure students reflect on the discussion, they can be assigned the last question from the script as a post-discussion exercise. They can also be asked specifically about frameworks and concepts related to sustainability.  

 

Role-play scenario narrative and description of roles: 

Eva Walker recently started reporting about on-campus traffic issues for the student newspaper. She would have preferred to do more human-interest stories, but as a new member of the staff who had just moved from intern to full-time, she was happy to get whatever opportunity she could. Eva was studying both journalism and creative writing, and this was her dream on-campus job. She also realised that, even though many stories at first didn’t appear to her as though she would be interested in them, as she dug deeper she eventually found an angle with which she could strongly relate.  

One weekday morning, Eva was working on yet another story on parking woes when Amina Ali, one of the editorial staff members, texted her to say that there had been an accident on campus; she just passed it at the intersection of the library and the recreation building, and it might be worth covering. Eva was at the library, and within no time, reached the spot of the accident.  

When Eva arrived, a police vehicle, an ambulance, and a fire engine were all present at the scene, and near the accident site, an e-scooter lay smashed into a tree. It looked like the rider was sitting in the ambulance and was being treated by the medical staff. A little further away, Eva noticed the police speaking to a young woman in a wheelchair. Although Eva’s first instinct was to try to talk to the police or the medical staff to ascertain what had happened, she realised this probably wasn’t the best moment and she would have to wait until later for the official version of the event.  

She looked around and saw a group of four students leaning against a wall with drinks in their hands. A couple of them were vaping. Eva thought that they looked like they had been here for a while, and she walked over to ask them what had happened. From the account they gave her, it appeared as if the e-scooter rider was coming around the bend at some speed, saw the woman in the wheelchair a little too late to ride past her, and, to avoid hitting her, leapt off his e-scooter and let the vehicle hit the tree. Things happened very quickly and no one was exactly sure about the sequence of events, but this was the rough story she got.  

Later, she called the police department on campus and was able to speak with one of the officers to get an official account. The story was very similar to what she already knew. She did find out that nobody was seriously hurt and that the only injuries were to the e-scooter rider and were taken care of at the scene by the medical staff. When she asked about who was to blame or if any legal action was expected, she was told that there were no laws around the use of helmets or speeding for e-scooters yet and that she should reach out later for more information. Eva wrote up what she had so far, sent it over to the editorial staff, and considered her work done.  

But as she was walking back to her halls of residence that evening, her attention was drawn to the large number of e-scooters parked near the library. As she crossed the central campus, she noticed even more e-scooters lying about the intersections, and there was a litter of them around the residence hall. She wondered why she hadn’t noticed them before. Her attention was drawn today, she thought, because of the accident and also because she saw a good Samaritan remove an e-scooter from the sidewalk, as it was blocking the path of one of the self-driving food delivery robots. It’s a sign, Eva thought, this is what she needs to look for more in her next article, the use of e-scooters on campus.  

Eva recognised that, to write a balanced and informative article, as she had been taught to do, she would have to look at many different aspects of the use of e-scooters as well as look broadly at mobility on campus and the use of battery powered vehicles. She had also recently seen e-bikes on campus and, in addition to the food delivery robots, service robots in one of the buildings that she assumed was either delivering paperwork or mail. The accident had also made her realise that, when it came to mobility, accessibility was something that never crossed her mind but that she now understood was an important consideration. She hoped to learn more about it as her research progressed.  

As background research for the article, Eva started reading up on articles and studies published about e-scooters, e-bikes, and urban mobility and came across a range of concerns that had been raised beyond accessibility. First, there were reports that e-scooters are not as environmentally friendly as many service providers had made them out to be. This is related to the production of the battery as well as the short lifespan of the vehicles, and as of yet, there has been no procedure implemented to reuse them (Pyzyk, 2019). Second, there were reports of littering, where e-scooters are often left on sidewalks and other places where they restrict movement of other vehicles, pedestrians, and in particular, those in wheelchairs (Iannelli, 2021). Finally, it was also clear from the reports that accidents and injuries have increased due to e-scooters, especially since many riders do not wear safety gear and are often careless, even inebriated, as there were little to no regulations (2021). When she approached her editor with an outline for an article, she was advised to do some more reporting by talking with people who could shed more light on the issue.  

After some research, Eva shortlisted the following experts across fields related to e-scooters for an interview, and once she spoke with them, she realised that it would help her if she could get them to have a dialogue and respond to some of the questions that were raised by other experts. Therefore, she decided to conduct a focus group with them so that she achieved her goal of a balanced article and did not misrepresent any expert’s point of view.  

 

Experts/roles for discussion: 

1. Bryan Avery is co-founder and chief technology officer (CTO) of RideBy, an e-scooter company. RideBy is one of the options available on campus. Born in a small town, Bryan used to ride his bicycle everywhere while growing up, and for him, founding and leading an e-scooter company provided a chance to merge his interests in personal transportation and new forms of energy. He was a chemical engineer by training, and at a time when most of his friends ended up working for big oil companies, Bryan decided to work on alternative fuels and found himself developing expertise and experience with batteries. For most of the software- and mobile device-related development, RideBy outsourced the work and utilised ready-to-configure systems that were available. By only keeping the core device and battery functionality in-house, they could focus on delivering a much stronger product. Overall, he is quite happy with the success of RideBy so far and can’t help but extol the difference it can make for the environment.  

 

2. Abiola Abrams is a professor of transportation engineering and an expert on mobility systems. Her work combines systems engineering, computer science, and data analytics. Her recent research is on urban mobility and micro-mobility services, particularly e-bikes. In her research, Dr. Abrams has looked at a host of topics related to e-bikes, many of which are also applicable to e-scooters, including the optimisation of hubs for availability, common path patterns of users, subscription use models, and the e-waste and end of lifecycle for these vehicles. Increasingly, she has become concerned about the abuse of some of these services, especially in cities that attract a lot of tourists, and about the rough use of the vehicles, so much so that many do not even last for a month. In a new project, she is investigating the effect of e-vehicles on the environment and has found that there is mixed evidence for how much difference battery-operated vehicles will actually make for climate change compared to vehicles that use fossil fuels.  

 

3. Marco Rodrigues works as transportation director for the local county government where the university is based. As part of a recent bilateral international exchange, he got the opportunity to spend time in different cities in Germany to learn about local transportation. He realised very quickly that local transportation was very different in Germany; residents had a range of public, shared options that were missing in the United States. However, he also realised that e-mobility services were being considered across both countries. He investigated this further and found that Germany waited until it could pass some regulations before allowing e-mobility operators to offer services; helmets were mandatory on e-scooters and e-bikes, and riders had to purchase a nominal insurance policy. He also learned that there were strict rules around the sharing of data generated by the vehicles as well as the apps used by riders.  

 

4. Judy Whitehouse is director of infrastructure and sustainability on campus and responsible for planning the long-term development of the campus from a space perspective, but also increasingly from a sustainability dimension. As the number of students has increased, so has the need for more infrastructure, including classrooms and halls of residence. This has also resulted in greater distances to be traveled on campus. Judy regards e-mobility options as a necessary component of campus life and has been a strong supporter for them. Lately, she has been called into meetings with safety and emergency management people discussing the issue of increased accidents on campus and the littering of e-vehicles across the campus. Not only is it bad for living on campus, but it is also bad for optics. A recent photo featured in the campus newspaper was a stark reminder of just how bad it can look. She is further divided on the use of e-scooters due to misgivings about the sustainability of battery use, as new research suggests that manufacturing batteries and disposing them are extremely harmful for the environment.  

 

5. Aaron Schneider heads Campus Mobility, a student interest group focused on autonomous vehicles development and use. The group members come from different degree programmes and are interested in both the technical dimensions of mobile solutions and the policy issues surrounding their implementation. Aaron himself is a computer science student with interests in data science, and with some of his fellow members from the policy school, he has been analysing a range of mobility-related datasets that are publicly available online. Of these, the data on accidents is quite glaring, as the number of accidents in which e-scooters are involved has gone up significantly. Aaron and his friends were intrigued by their findings and approached some of the companies to see if they would share data, but they were disappointed when they could not get access. Although the companies said it was due to privacy reasons, Aaron was not too convinced by that argument. He was also denied access to any internal reports about usage patterns of accidents. Ideally, he would have liked to know what algorithms were used for optimising delivery and access, but he knew he was not going to get that information.  

  

6. Sarah Johnson is the head of accessibility services on campus and is responsible for both technology- and infrastructure-related support for students, faculty, and staff. The growth of the physical campus and the range of technological offerings has significantly increased the workload for her office, and they are really strained in terms of people and expertise. The emphasis from the university leadership is largely on web and IT accessibility, as teaching and other services are shifting quickly online, but Sarah realises that there is still an acute need to provide physical and mobility support to many members of the community. Although all the new buildings are up to code in terms of accessibility, there is still work to be done both for the older buildings and especially for mobility. Campus beautification does not always go along with access. She is also worried about access to devices, as taking part in any campus activity requires not just a computer, but also access to mobile devices that are out of reach economically for many and not easy to use.  

 

Role-play script: 

To help get the dialogues started and based on her prior conversation with the group, Eva has prepared some initial questions:  

  1. What role are you playing and, from your perspective, what do you see as the biggest pros of using e-vehicles, especially e-scooters on campus?
  2. From your perspective, what do you see as the biggest downside of using e-vehicles, especially e-scooters on campus?
  3. Can you confidently say that e-scooters are an environmentally friendly option?
  4. What current accessibility accommodations would be impacted by the use of e-vehicles, and what new, potential accessibility accommodations might arise from increased use of e-vehicles?
  5. Would we be better off waiting for more regulations to come before deploying these vehicles on campus and, if so, what should those regulations look like?
  6. Should we use automatic regulation of speed on the vehicle based on where it is and/or inform authorities if it is violated?
  7. Can we control where it can go or penalise if not put back?
  8. What guidelines do you recommend for e-scooter usage on campus?

Learning and teaching notes: 

This case study offers learners an explorative journey through the multifaceted aspects of deploying off-grid renewable solutions, considering practical, ethical, and societal implications. It dwells on themes such as Engineering and Sustainable Development (emphasizing the role of engineering in driving sustainable initiatives) and Engineering Practice (exploring the application of engineering principles in real-world contexts). 

The dilemma in this case is presented in six parts. If desired, a teacher can use Part one in isolation, but Parts two and three develop and complicate the concepts presented in Part one to provide for additional learning. The case study allows teachers the option to stop at multiple points for questions and/or activities, as desired.

In accordance with a report from the International Energy Agency (IEA) and statistics provided by the World Bank, approximately 633 million individuals in Africa currently lack access to electricity. This stark reality has significant implications for the remote villages across the continent, where challenges related to energy access persistently impact various aspects of daily life and stall social and economic development. In response to this critical issue, the deployment of off-grid renewable solutions emerges as a promising and sustainable alternative. Such solutions have the potential to not only address the pressing energy gap but also to catalyse development in isolated regions. 

Situated in one of Egypt’s most breathtaking desert landscapes, Siwa holds a position of immense natural heritage importance within Egypt and on a global scale. The region is home to highly endangered species, some of which have restricted distributions found only in Siwa Oasis. Classified as a remote area, a particular community in Siwa Oasis currently relies predominantly on diesel generators for its power needs, as it remains disconnected from the national grid. Moreover, extending the national grid to this location is deemed economically and environmentally impractical, given the long distances and rugged terrain. 

Despite these challenges, Siwa Oasis possesses abundant renewable resources that can serve as the foundation for implementing a reliable, economical, and sustainable energy source. Recognising the environmental significance of the area, the Egyptian Environmental Affairs Agency (EEAA) declared Siwa Oasis as a protected area in 2002. 

 

Part one: Household energy for Siwa Oasis  

Imagine being an electrical engineer tasked with developing an off-grid, sustainable power solution for Siwa Oasis village. Your goal is to develop a solution that not only addresses the power needs but also is sustainable, ethical, and has a positive impact on the community. The following data may help in developing your solution.   

 

Data on Household Energy for Siwa Oasis:

 

Activities: 

  1. Analyse typical household appliances and their power consumption (lighting, refrigeration, pressing Iron).
  2. Simulate daily energy usage patterns using smart meter data.
  3. Identify peak usage times and propose strategies for energy conservation (example LED bulbs, etc)
  4. Calculate appliance power consumption and estimate electricity costs.
  5. Discussion:  

a. How does this situation relate to SDG 7, and why is it essential for sustainable development? 

b. What are the primary and secondary challenges of implementing off-grid solutions in remote villages? 

 

Part two: Power supply options 

Electricity supply in Siwa Oasis is mainly depends on Diesel Generators, 4 MAN Diesel Generators of 21 MW which are going to be wasted in four years, 2 CAT Diesel Generators of 5.2 MW and 1 MAN Diesel Generator 4 MW for emergency. Compare and contrast various power supply options for the household (renewable vs. fossil fuel). 

 

  1. Renewable: Focus on solar PV systems, including hands-on activities like solar panel power output measurements and battery sizing calculations. 
  2. Fossil fuel: Briefly discuss diesel generators and their environmental impact. 

 

The Siwa Oasis community is divided over the choice of power supply options for their households. On one hand, there is a group advocating for a complete shift to renewable energy, emphasising the environmental benefits and long-term sustainability of solar PV systems. On the other hand, there is a faction arguing to continue relying on the existing diesel generators, citing concerns about the reliability and initial costs associated with solar power. The community must decide which power supply option aligns with their values, priorities, and long-term goals for sustainability and energy independence. This decision will not only impact their day-to-day lives but also shape the future of energy use in Siwa Oasis. 

 

Optional STOP for questions and activities:

  1. Debate: Is it ethical to impose new technologies on communities, even if it’s for perceived improvement of living conditions?
  2. Discussion: How can engineers ensure the sustainability (environmental and operational) of off-grid solutions in remote locations?
  3. Activities: Students to design a basic solar PV system for the household, considering factors like energy demand, solar resource availability, and budget constraints.  

 

Part three: Community mini-grid via harnessing the desert sun 

Mini-grid systems (sometimes referred to as micro-grids) generally serve several buildings or entire communities. The abundant sunshine in Siwa community makes it ideal for solar photovoltaic (PV) systems and based on the load demand of the community, a solar PV mini grid solution will work perfectly. 

Electrical components of a typical PV system can be classified into DC and AC. 

 

DC components: The electrical connection of solar modules to the inverter constitutes the DC part of a PV installation. Its design requires particular care and reliable components, as there is a risk of significant accidents with high DC voltages and currents, especially due to electric arcs.  

The key DC components are:  

 

AC components: The equipment installed on the AC side of the inverter depends on the size and voltage class of the grid connection (low-voltage (LV), medium-voltage (MV), or high-voltage (HV) grid). Utility-scale PV plants usually require the following equipment:

Premise:  

There is an urgent global need to address the social and economic challenges relating to our world and the environment (Raper et al., 2022). The United Nations Sustainable Development Goals (SDGs) provide a framework for individuals, policy-makers and industries to work to address some of these challenges (Gutierrez-Bucheli et al., 2022). These 17 goals encompass areas such as clean energy, responsible consumption, climate action, and social equity. Engineers play a pivotal role in achieving these goals by developing innovative solutions that promote sustainability and they can use these goals to work to address broader sustainability objectives. 

Part of the strategy to ensure that engineers incorporate sustainability into their solution development is to ensure that engineering students are educated on these topics and taught how to incorporate considerations at all stages in the engineering process (Eidenskog et al., 2022). For instance, students need not only to have a broad awareness of topics such as the SDGs, but they also need lessons on how to ensure their engineering incorporates sustainable practice. Despite the increased effort that has been demonstrated in engineering generally, there are some challenges when the sustainability paradigm needs to be integrated into robotics study programs or modules (Leifler and Dahlin, 2020). This article details one approach to incorporate considerations of the SDGs at all stages of new robot creation: including considerations prior to design, during creation and manufacturing and post-deployment. 

 

1. During research and problem definition:

Sustainability considerations should start from the beginning of the engineering cycle for robotic systems. During this phase it is important to consider what the problem statement is for the new system, and whether the proposed solution satisfies this in a sustainable way, using Key Performance Indicators (KPIs) linked to the SDGs (United Nations, 2018), such as carbon emissions, energy efficiency and social equity (Hristov and Chirico, 2019). For instance, will the energy expended to create the robot solution be offset by the robot once it is in use? Are there long-term consequences of using a robot as a solution? It is important to begin engagement with stakeholders, such as end-users, local communities, and subject matter experts to gain insight into these types of questions and any initial concerns. Educators can provide students with opportunities to engage in the research and development of robotics technology that can solve locally relevant problems and benefit the local community. These types of research projects allow students to gain valuable research experience and explore robotics innovations through solving problems that are relatable to the students. There are some successful examples across the globe as discussed in Dias et al., 2005. 

 

2. At design and conceptualisation:

Once it is decided that a robot works as an appropriate solution, Sustainability should be integrated into the robot system’s concept and design. Considerations can include incorporating eco-design principles that prioritise resource efficiency, waste reduction, and using low-impact materials. The design should use materials with relatively low environmental footprints, assessing their complete life cycles, including extraction, production, transportation, and disposal. Powered systems should prioritise energy-efficient designs and technologies to reduce operational energy consumption, fostering sustainability from the outset. 

 

3. During creation and manufacturing:

The robotic system should be manufactured to prioritise methods that minimise, mitigate or offset waste, energy consumption, and emissions. Lean manufacturing practices can be used to optimise resource utilisation where possible. Engineers should be aware of the importance of considering sustainability in supply chain management to select suppliers with consideration of their sustainability practices, including ethical labour standards and environmentally responsible sourcing. Robotic systems should be designed in a way that is easy to assemble and disassemble, thus enabling robots to be easily recycled, or repurposed at the end of their life cycle, promoting circularity and resource conservation. 

 

4. Deployment:

Many robotic systems are designed to run constantly day and night in working environments such as manufacturing plants and warehouses. Thus energy-efficient operation is crucial to ensure users operate the product or system efficiently, utilising energy-saving features to reduce operational impacts. Guidance and resources should be provided to users to encourage sustainable practices during the operational phase. System designers should also implement systems for continuous monitoring of performance and data collection to identify opportunities for improvement throughout the operational life. 

 

5. Disposal:

Industrial robots have an average service life of 6-7 years. It is important to consider their end-of-life and plan for responsible disposal or recycling of product components. Designs should be prioritised that facilitate disassembly and recycling (Karastoyanov and Karastanev, 2018). Engineers should identify and safely manage hazardous materials to comply with regulations and prevent environmental harm. Designers can also explore options for product take-back and recycling as part of a circular economy strategy. There are various ways of achieving that. Designers can adopt modular design methodologies to enable upgrades and repairs, extending their useful life. Robot system manufacturers should be encouraged to develop strategies for refurbishing and reselling products, promoting reuse over disposal. 

 

Conclusion: 

Sustainability is not just an option but an imperative within the realm of engineering. Engineers must find solutions that not only meet technical and economic requirements but also align with environmental, social, and economic sustainability goals. As well as educating students on the broader topics and issues relating to Sustainability, there is a need for teaching considerations at different stages in the robot development lifecycle. Understanding the multifaceted connections between sustainability and engineering disciplines, as well as their impact across various stages of the engineering process, is essential for engineers to meet the challenges of the 21st century responsibly.

Learning and teaching notes:

At COP26, H.E. President Muhammadu Buhari announced Nigeria’s commitment to carbon neutrality by 2050. This case involves an engineer who is one of the stakeholders invited by the president of Nigeria to implement an Energy Transition Plan (ETP). It requires the engineer, who is a professional and well experienced in renewable energy and energy transition, to deliver a comprehensive decarbonisation roadmap that will ensure net zero emissions.

This case study addresses two of AHEP 4’s themes: The Engineer and Society (acknowledging that engineering activity can have a significant societal impact) and Engineering Practice (the practical application of engineering concepts, tools and professional skills). To map this case study to AHEP outcomes specific to a programme under these themes, access AHEP 4 here and navigate to pages 30-31 and 35-37.

The dilemma in this case is presented in two parts. If desired, a teacher can use Part one in isolation, but Part two develops and complicates the concepts presented in Part one to provide for additional learning. The case allows teachers the option to stop at multiple points for questions and / or activities, as desired.

Dilemma – Part one:

You are an electrical engineer working as a technical consultant in an international organisation aiming to  transform the global energy system to secure a clean, prosperous, zero-carbon future for all. The organisation is one of the stakeholders invited by the federal government of Nigeria to implement the country’s new Energy Transition Plan (ETP) and you are given the task of creating a comprehensive decarbonisation roadmap and presenting it at the stakeholder meeting.

 

Optional STOP for questions and activities:

1. Discussion: In what ways could an electrical engineer bring needed expertise to the ETP? Why are engineers essential to ensuring a zero-carbon future? Should engineers be involved in policy planning? Why or why not?

2. Activity: Wider context research: Nigeria is currently an oil-producing country. What might policy makers need to consider about this reality when implementing an ETP? How strongly should you advocate for a reduction of the use of fossil fuels in the energy mix?

3. Discussion and activity: List the potential benefits and risks to implementing the ETP. Are these benefits and risks the same no matter which country they are implemented in?

4. Activity: Research and outline countries that have attained a zero emission target. What are their energy distribution mixes? Based on this information, what approach should Nigeria take and why?

5. Activity: What will be your presentation strategy at the stakeholder meeting? What will you advocate for and why? What ethical justifications can you make for the plan you propose?

 

Dilemma – Part two:

At the stakeholder meeting, you were given the opportunity to present your decarbonisation roadmap and afterwards faced serious opposition by the chief lobbyist of the Fossil Fuel and Mining Association, Mr. Abiola. Mr. Abiola is of the opinion that because Nigeria contributes less than 1% to the global emissions, it should not be held accountable for climate change, and therefore no country-wide climate policy is necessary. Furthermore, he fears the domestic market for coal that is used to produce electricity as well as the global market for fossil fuels will shrink because of the new policy. He also argues that a shift away from coal and fossil fuels could result in challenges to the security of supply, since renewables are by definition unreliable and volatile. Other stakeholders, such as activists and environmental experts, also voiced different concerns and opinions. They argue that time has already run out, and no country can delay decarbonisation plans no matter how small their impact on the global total. This conflict has resulted in disagreements in the negotiation.

 

Optional STOP for questions and activities:

1. Debate: Do different countries have different ethical responsibilities when it comes to decarbonisation? Why or why not? If so, for what reasons?

2. Discussion: How should countries weigh the short-term versus long-term benefits and burdens of the energy transition? What role do governments and corporations play in managing those? What role should citizens play?

3. Discussion: How will you prepare for and handle opposing questions to your roadmap plan? 

4. Activity: Create a participatory stakeholder engagement plan embedded in the overall decarbonisation strategy.

5. Activity: How will you utilise the different renewable energy mix to provide 100% access to electricity and ensure security of supply as an electrical engineer?

Learning and teaching notes: 

This case study requires a newly appointed engineer to make a decision about whether or not to sell unsuitable equipment to a developing country. Situated in Ghana, the engineer must weigh perspectives on environmental ethics that may differ from those informed by a different cultural background, as well as navigate unfamiliar workplace expectations. 

The engineer’s own job security is also at stake, which may complicate decision-making. As a result, this case has several layers of relations and potential value-conflicts. These include values that underlie assumptions held about honesty, integrity, the environment and its connection to human life and services. 

This case study addresses two of the themes from the Accreditation of Higher Education Programmes fourth edition (AHEP4): The Engineer and Society (acknowledging that engineering activity can have a significant societal impact) and Engineering Practice (the practical application of engineering concepts, tools and professional skills).

Dilemma – Part one: 

You have just graduated from university as a mechanical engineer and you are starting your first job as a sales engineer for JCD Engineering, a company that designs and manufactures pumping equipment. JCD has recently expanded operations in sub-Saharan Africa and you took the job because you were excited for the opportunity to travel and work in a country and culture different from your own.  

For your first project, you have been asked to put together quite a large bid for a water pumping aid project for some farms in northern Ghana. It just so happens that there is a trade show being held in Accra, so your manager has suggested you attend the show with a colleague to help on the company stand and combine this with a site visit to where the pumping equipment is to be installed. A representative from the aid organisation agrees to drive you to where the project will be sited before the trade show takes place. 

On arrival in Ghana, you are met by the rep to take you on your journey up country. This is your first visit to a developing country; you are excited, a little apprehensive and quite surprised by disorganisation at the airport, poor infrastructure, and obvious poverty in the villages up country. Still, you immediately see the difference that water pump installation could make to improve quality of life in villages. After two days of travelling, you eventually arrive at the village where the project JCD is bidding on will be situated. You are surprised to hear that the aid rep is quite cynical about engineering aid projects from the UK; this is because many have failed and she hopes that this won’t be another one. She is very busy and leaves you with local school teacher Amadou, who will host you during your stay and act as your interpreter. 

The local chief, farmers, and their families are very excited to see you and you are taken aback by the lavish food, dancing, and reception that they have laid on especially for you. You exchange social media contacts with Amadou, who you understand has been instrumental in winning this contract. You get excited about working with Amadou on this project and the prospect of improving the livelihoods of the locals with better access to clean water. 

After some hours you get shown some of the existing pumping equipment, but you don’t recognise it and it has obviously been left idle for some time and looks to be in a poor state. The farmers appear confused and are surprised that you aren’t familiar with the pumps. They explain that the equipment is from China and was working well for many years. They understand how it operates and have even managed to repair some of the fittings in local workshops, but there are now key parts they have been waiting many months for and they assume that you have brought them with you. 

You try to explain through Amadou that there has been some misunderstanding and that you don’t have the spares but will be quoting for replacement equipment from your company in the UK. This is not what the farmers want to hear and the mood changes. They have spent many years getting to know this kit and now they can even locally fabricate some of the parts. Why would you change it all now? The farmers start shouting and Amadou takes you to one side and suggests you should respond by offering them something in return. 

What should you offer them? 

 

Optional STOP for questions and activities: 

1. Discussion: What is your initial reaction to the miscommunication? Does it surprise you? What might your initial reaction reveal to you about your own perspectives and values? 

2. Discussion: What is your initial reaction to the reception given to you? Does it surprise you? What might your initial reaction reveal to you about your own perspectives and values? 

3. Activity: Technical integration – undertake an electrical engineering technical activity related to water pumps and their power consumption against flow rates and heads. 

4. Discussion and activity: List the potential benefits and risks to implementing water pump technology compared to traditional methods of water collection. Are these benefits and risks the same no matter which country they are implemented in? 

5. Activity: Research water pumping in developing countries. What are the main technical and logistical issues with this technology? Are there any cultural issues to consider?  

6. Activity: This activity is related to optional pre-readings on environmental ethics. Consider how your perspective is related to the following environmental values, and pair/share or debate with a peer. 

 

Dilemma – Part two: 

You reluctantly backtrack a little on what you said earlier and convince Amadou and the farmers that you will be able to sort something out. Back in Accra at the local trade show, you manage to source only a few spares as a quick fix since you had to pay for them yourself without your colleague noticing. The aid representative agrees to take them up country next time she travels. 

You arrive back in the UK and begin to prepare the JCD bid. You are aware that the equipment from your company is very different to the Chinese kit that the farmers already have. It is designed to run on a different voltage and uses different pipe gauges throughout for the actual water pumping. The locally fabricated spares will definitely not connect to the JCD components you will be specifying. 

You voice your concerns to your manager about the local situation but your manager insists that it is not your problem and the bid will not win if it is not competitive. Sales in your department are not good at the moment, and after all you are a new employee on probation and you want to make a good first impression. 

Having further investigated some comments Amadou made on the trip, you discover that the water table has dropped by several metres in this part of Ghana over the last five years and you realise that the equipment originally quoted for might not even be up to the job! 

 

Optional STOP for questions and activities: 

1. Discussion: Should you disclose these newly discovered concerns about the water table height or keep quiet? 

2. Discussion: Do you continue to submit the bid for equipment that you know may be totally inappropriate? Why, or why not? 

3. Activity: Role-play a conversation between the engineer and the JCD manager about the issues that have been discovered. 

4. Discussion and activity: Research levels of the water table in West Africa and how they have changed over the last 50 years. Is there a link here to climate change? What other factors may be involved? 

5. Discussion: Environmental ethics deals with assumptions that are often unstated, such as the obligation to future generations. Some people find that our obligation is greater to people who exist at this moment than to those that don’t yet exist. Do you agree or disagree with this position? Why? Can we maintain an obligation to future generations while simultaneously saying that this must be weighed against the obligations in the here and now? 

6. Activity: Both cost-benefit and value trade-off analyses are valuable approaches to consider in this case. Determine the possible courses of action and undertake both types of analysis for each position by considering both short- and long-term consequences. (Use the Mapping actors and processes article to help with this activity.) 

7. Activity: Using reasoning and evidence, create arguments for choosing one of the possible courses of action. 

8. Activity: Use heuristics to analyse possible courses of action. One heuristic is the Environmental ethics decision making guide. Another is the 7-step guide to ethical decision-making.

Case enhancement: Business growth models in engineering industries within an economic system

Activity: Defending a profit-driven business versus a non-profit-driven business.

Author: Dr Sandhya Moise (University of Bath).

 

Overview:

This enhancement is for an activity found in the Dilemma Part one, Point 4 section of the case: “In a group, split into two sides with one side defending a profit-driven business and the other defending a non-profit driven business. Use Maria’s case in defending your position.” Below are several prompts for discussion questions and activities that can be used. These correspond with the stopping points outlined in the case. Each prompt could take up as little or as much time as the educator wishes, depending on where they want the focus of the discussion to be.

 

Session structure:

1. As pre-class work, the students can be provided the case study in written format.

2. During class, the students will need to be introduced to the following concepts, for which resources are provided below (~20 min):

3. Group activity (15 min +)

4. Whole class discussion/debate (15 min +)

 

Learning resources:

Ethics in Engineering resources:

Professional Codes of Conduct resources:

Corporate Social Responsibility Resources:

ESG Mandate Resources:

In recent years, there have been calls for more corporate responsibility in environmental and socioeconomic ecosystems globally. For example:

In 2017, the economist Kate Raworth set out to reframe GDP growth to a different indicator system that reflects on social and environmental impact. A Moment for Change?

Further reading:

 

Group Activity – Structure:

Split the class into two or more groups. One half of the class is assigned as Group 1 and the other, Group 2. Ask students to use Maria’s case in defending their position.

 

Group activity 1:

Group 1: Defend a profit-driven business model – Aims at catalysing the company’s market and profits by working with big corporations as this will enable quicker adoption of technology as well as economically benefit surrounding industries and society.

Group 2: Defend a non-profit driven business – Aims at preventing the widening of the socioeconomic gap by working with poorly-funded local authorities to help ensure their product gets to the places most in need (opportunities present in Joburg).

 

Pros and Cons of each approach:

Group 1: Defend a profit-driven business model:

Advantages and ethical impact:

Disadvantage and ethical impacts:

Group 2: Defend a non-profit driven business:

Advantages and ethical impact:

Disadvantage and ethical impacts:

 

Relevant ethical codes of conduct examples:

Royal Academy’s Statement of Ethical Principles:

Both of the above statements can be interpreted to mean that engineers have a professional duty to not propagate social inequalities through their technologies/innovations.

 

Discussion and summary:

This case study involves very important questions of profit vs values. Which is a more ethical approach both at first sight and beyond? Both approaches have their own set of advantages and disadvantages both in terms of their business and ethical implications.

If Maria decides to follow a profit-driven approach, she goes against her personal values and beliefs that might cause internal conflict, as well as propagate societal inequalities.

However, a profit-driven model will expand the company’s business, and improve job opportunities in the neighbourhood, which in turn would help the local community. There is also the possibility to establish the new business and subsequently/slowly initiate CSR activities on working with local authorities in Joburg to directly benefit those most in need. However, this would be a delayed measure and there is a possible risk that the CSR plans never unfold.

If Maria decides to follow a non-profit-driven approach, it aligns with her personal values and she might be very proactive in delivering it and taking the company forward. The technology would benefit those in most need. It might improve the reputation of the company and increase loyalty of its employees who align with these values. However, it might have an impact on the company’s profits and slow its growth. This in turn would affect the livelihood of those employed within the company (e.g. job security) and risks.

Case Enhancement: Choosing to install a smart meter

Activity: Technical integration – Practical investigation of electrical energy.

Author: Mr Neil Rogers (Independent Scholar).

 

Overview:

This enhancement is for an activity found in the Dilemma Part two, Point 1 section of the case: “Technical integration – Undertake an electrical engineering technical activity related to smart meters and the data that they collect.”

This activity involves practical tasks requiring the learner to measure parameters to enable electrical energy to be calculated in two different scenarios and then relate this to domestic energy consumption. This activity will give technical context to this case study as well as partly address two AHEP themes:

This activity is in three parts. To fully grasp the concept of electrical energy and truly contextualise what could be a remote and abstract concept to the learner, it is expected that all three parts should be completed (even though slight modifications to the equipment list are acceptable).

Learners are required to have basic (level 2) science knowledge as well as familiarity with the Multimeters and Power Supplies of the institution.

Learners have the opportunity to:

Teachers have the opportunity to:

 

Suggested pre-reading:

To prepare for these practical activities, teachers may want to explain, or assign students to pre-read articles relating to electrical circuit theory with respect to:

 

Learning and teaching resources:

 

Activity: Practical investigation of electrical energy:

Task A: Comparing the energy consumed by incandescent bulbs with LEDs.

1. Power in a circuit.

By connecting the bulbs and LEDs in turn to the PSU with a meter in series:

a. Compare the wattage of the two devices.

b. On interpretation of their data sheets compare their luminous intensities.

c. Equate the quantity of each device to achieve a similar luminous intensity of approximately 600 Lumens (a typical household bulb equivalent).

d. now equate the wattages required to achieve this luminous intensity for the two devices.

 

2. Energy = Power x Time.

The units used by the energy providers are kWh:

a. Assuming the devices are on for 6 hours/day and 365 days/year, calculate the energy consumption in kWh for the two devices.

b. Now calculate the comparative annual cost assuming 1 kWh = 27p ! (update rate).

 

3.  Wider implications.

a. Are there any cost-benefit considerations not covered?

b. How might your findings affect consumer behaviour in ways that could either negatively or positively impact sustainability?

c. Are there any ethical factors to be considered when choosing LED lightbulbs? For instance, you might investigate minerals and materials used for manufacturing and processing and how they are extracted, or end-of-life disposal issues, or fairness of costs (both relating to production and use).

 

Task B: Using a plug-in power meter.

1. Connect the power meter to a dishwasher or washing machine and run a short 15/30 minute cycle and record the energy used in kWh.

2. Connect the power meter to a ½ filled kettle and turn on, noting the instantaneous power (in watts) and the time taken. Then calculate the energy used and compare to the power meter.

3. Connect the power meter to the fan heater and measure the instantaneous power. Now calculate the daily energy consumption in kWh for a fan heater on for 6 hours/day.

4. Appreciation of consumption of electrical energy over a 24 hour period (in kWh) is key. What are the dangers in reading instantaneous energy readings from a smart meter?

 

Task C: Calculation of typical domestic electrical energy consumption.

1. Using the list of items in Appendix A, calculate the typical electrical energy usage/day for a typical household.

2. Now compare the electrical energy costs per day and per year for these three suppliers, considering how suppliers source their energy (i.e. renewable vs fossil fuels vs nuclear etc).

 

Standing charge cost / day Cost per kWh Cost / day Cost / year
A) 48p 28p
B) 45p 31p
C) 51p 27p

 

3. Does it matter that data is collected every 30 minutes by your energy supplier? What implications might changing the collection times have?

4. With reference to Sam growing marijuana in the case, how do you think this will show up in his energy bill?

 

Appendix A: Household electrical devices power consumption:

Typical power consumption of electrical devices on standby (in Watts).

Wi-Fi router 10
TV & set top box 20
Radios & alarms 10
Dishwasher  5
Washing machine  5
Cooker & heat-ring controls 10
Gaming devices 10
Laptops x2 10

 

Typical consumption of electrical devices when active (in Watts) and assuming Gas central heating.

TV & set top box (assume 5 hours / day) 120
Dishwasher (assume 2 cycles / week) Use calculated
Washing machine (assume 2 cycles / week) Use calculated
Cooking (oven, microwave etc 1 hour / day) 1000

Theme: Universities’ and business’ shared role in regional development; Collaborating with industry for teaching and learning; Knowledge exchange; Research; Graduate employability and recruitment.

Author: Prof Matt Boyle OBE (Newcastle University).

Keywords: Electrification; Collaboration Skills; Newcastle.

Abstract: Driving the Electric Revolution is led by Newcastle and is a collaborative R&D project to build supply chains in Power Electronics Machines and Drives. The University led the bid and as we amass supply chain capability we will generate £ Billions in GVA.

 

Newcastle University has been embedded in the academic and industrial development of the North East of England since 1834. Recently, one of its core competencies, Machines and Drives research, has been used to attract investment to the region from Industry and Government helping to increase the economic prospects for the North East region.

Newcastle University is the national lead organisation for Driving the Electric Revolution Industrialisation Centres an Industrial Strategy Challenge Fund Wave 3 competition. The centres serve two purposes,

  1. A focal point for development of manufacturing processes in Power Electronics, Machines and Drives (PEMD) through investment in cutting edge manufacturing equipment.
  2. The training of researchers, students, employees of industrial partners on these important new processes.

The Driving the Electric Revolution (DER) Industrialisation Centres (DERIC) project aims to accelerate UK industrialisation of innovative and differentiated PEMD manufacturing and supply chain solutions. They are doing this by creating a national network to coordinate and leverage the capabilities of 35 Research and Technology Organisations (RTO) and academic establishments, based within four main centres.  Supported by 166 industrial partners it represents the largest coordinated industrialisation programme the UK PEMD sector has ever seen.

Newcastle University has, in living memory, always been at the forefront of Electric Machines and Drives innovation globally. It was inevitable that Newcastle would lead the DER project given its pedigree, reputation and the fact that it was supported by several companies in several sectors, Automotive, Aerospace and domestic products who undertake product research in the North East and who seek to manufacture in the UK if possible.

Newcastle did recognise however that it couldn’t deliver the government programme alone. There were four institutions which formed a consortium to bid into the competition, Newcastle University, University of Strathclyde, Warwick Manufacturing Group and the Compound Semiconductor Applications Catapult in Newport South Wales. Over time they have been joined by University of Nottingham, University of Birmingham, Swansea University and University of Warwick. Letters of support were received from 166 Industry partners, 27 FE and HE organisations expressed support as did 13 RTOs. Although the national bid was led by Newcastle, it took a more North East regional view in development of its delivery model.

Therefore, in addition to this national work, Newcastle extended their DERIC application beyond Newcastle to Sunderland where they worked with Sunderland council to establish a DERIC research facility in the area. Sunderland city council worked with Newcastle to acquire, fit out and commission the lab which received equipment from the project and is due to open in 2022.

Nationally the primary outcome is the establishment of the Driving the Electric Revolution Industrialisation Centres and the network.

The four DERIC act as focal points for the promotion of UK PEMD capabilities. They design develop and co-sponsor activities at international events. They send industrial representatives to meet with clients and research partners from UK, Europe and Asia, as well as developing a new UK event to attract leading PEMD organisations from around the globe.

In Newcastle the university’s sponsorship of both the national project as well as the DERIC in the North East is helping attract, retain and develop local innovation and investment. The equipment granted by the DER Challenge to the centre includes a Drives assembly line as well as an advanced Machines line. The DERIC is focused primarily in the development of manufacturing processes using the granted equipment. The equipment was selected specifically with these new processes in mind. The success of the DERIC program already means that the country and the region have attracted substantial inward investment.

Investments by three companies came to the North East because of the capability developed in the region. They have all agreed partnerships with the university in the process of establishing, acquiring and investing in the North East. The three companies are:

  1. British Volt mission is to accelerate the electrification of society. They make battery cells. Their Gigaplant in Northumberland will be the second Gigaplant in the UK. They are investing £1Bn into the region creating around 5,000 jobs both at the plant and in the supply chain.
  2. Envision also make batteries. Unlike British volt the Envision cell is a Gel pack. Envision has the first Gigaplant in the UK at Sunderland. They are investing a further £450M to expand the plant in Sunderland and potentially another £1.8Bn by 2030.
  3. Turntide Technologies invested £110M into the region acquiring three businesses. These have all in some fashion been supported by and supportive of the PEMD capability at Newcastle over the past six decades.

The university has worked tirelessly to help create an ecosystem in the region for decarbonisation and electrification.

The last stage of this specific activity is the creation of the trained employees for this new North East future. The university, collaborating across the country with DER partners, is embarking on an ambitious plan to help educate, train and upskill the engineers, scientists and operators to support these developments. It is doing this by collaborating, for the North East requirement, with the other universities and further education colleges in the region. Industry is getting involved by delivering a demand signal for its requirements. The education, training and up skilling of thousands of people over the next few years will require substantial investments by both the educators in the region as well as industry.

As the pace of electrification of common internally combusted applications accelerates the need for innovation in the three main components of electrification, power source, drive and machine will grow substantially. The country needs more electrification expertise. The North East region has many of the basic building blocks for a successful future in electrification. Newcastle University and its Academic and Industrial partners have shown the way ahead by collaborating, leading to substantial inward investment which will inevitably lead to greater economic prosperity for the region. Further information is available from the Driving the Electric Revolution Industrialisation Centres website. In addition, there are annual reports and many events hosted, sponsored or attended by the centres.

Abstract: This case study deals with a collaboration between KCL and National Grid on a EPSRC project. The project deals with assessing the impact of renewable energy sources on the electricity grid. This assessment will be carried out by using a transmission grid model provided by National Grid and device models developed by KCL.

 

Topic of the case study

This case study deals with the development of advanced models to study the impact of renewable energy sources, and more in general, inverter-based devices, on the UK transmission grid. More specifically, this project focuses on the impacts in terms of voltage and current distortion. This topic is referred to as ‘power quality’ in the specialist literature.

Aims

This research was motivated by various reports presented in the technical literature in the last decade, where a general increase of harmonic levels has been observed. A similar trend has been reported in several countries, simultaneously to the installation of increasing levels of renewable energy sources and other inverter-based devices. These reports have created some concerns about harmonic management in the future, when more renewable energy sources will be in services. Ultimately, the project aims at forecasting harmonic levels in 2050, and at determining impact on the equipment, and possible mitigating solutions.

Collaborating parties

This case study involved the collaboration between the Department of engineering at King’s College London and National Grid UK.

Project set up

Power quality is a specialist area within power systems that deals with deviation of voltage and current waveforms from the nominal values, in terms of both amplitude and frequency. The academic PI worked for a few years in the power industry, with the aim of specialising in power quality and understanding the issues faced by the power industry, as well as the tools that are used to carry out power system studies. The industrial PI is an expert in the area of power quality and has been involved with many standardisation groups as well as professional organisation to help developing common tools to harmonise the approach to power quality. Therefore, the two PIs have a similar expertise and background that allowed them to discuss and define common areas of research. When looking to develop such a specialist project, it is very important that all parties involved have a common ground, so that it is possible to interact and work in the same direction.

Outcomes

The project is still not finished, however, some of the original objectives have been achieved:

  1. A 2050 scenario has been developed, by using: transmission system model data provided by National Grid, device models developed through research and testing, and identification of future locations of renewable energy sources. Although the case is still under development, preliminary results indicate that harmonic levels are expected to increase, but they can be managed using existing design practice.
