• Question: In the area of power and energy, do you ever have moral conflict knowing this work is causing climate change?

      That’s a very important question. I am very concerned about climate change, and most of my work focuses on reducing energy use and CO2 emissions from buildings to try to help minimise the impact we are having on the climate. For example I am trying to show, using experiments and models, that we can use open windows instead of mechanical ventilation (fans) for fresh air in buildings.

      Yes, that’s why following reduce, reuse and recycle is so important – if we buy electrical equipment, it’s important to reuse or recycle it so that the components aren’t just sent to landfill. We should also try to reduce the amount of single use items we use.
      It can be difficult because the true cost of things (climate change wise) can be hidden e.g. we can save paper/ink by not printing documents but what is the cost in keeping them on a cloud server.
      I like to think my work in the nuclear industry is helping reduce the carbon footprint of energy production compared to coal and will help as energy requirements grow higher and higher, especially with the development of more AI applications and data centres.

    Yes, there is a moral tension at times. We manufacture resistors that are used in renewable energy systems, so our products directly support decarbonisation and the transition away from fossil fuels. At the same time, our manufacturing process is extremely energy-intensive, particularly the kilns, which currently run on natural gas.

    I think it’s important to be honest about that contradiction rather than ignore it. For me, the ethical responsibility comes from actively working to reduce the impact. We are always looking at improving efficiency, reducing waste, and exploring where renewables and lower-carbon alternatives can realistically be introduced into our processes. Being involved at a technical level means I can help drive those improvements, rather than stepping away and leaving the problem unchanged.

    So while the conflict exists, I see the work as part of a broader transition: supporting renewable technologies while continuously pushing to lower the footprint of how we manufacture the components that make them possible.
