In this thought-provoking episode of Rethink What Matters, host Paul welcomes Neil Kitching, an energy specialist at Green Heat and Water Technologies, to discuss the green heat revolution, sustainable energy solutions, and Scotland’s progress toward a low-carbon future. Neil, also the author of Carbon Choices, brings insight into how everyday actions and policies can help tackle the climate crisis.Neil starts by explaining Green Heat and Water Technologies’ work in supporting Scottish companies to implement net zero plans, which is now a requirement for companies receiving grants. “Climate is obviously very crucial to the future of the economy,” Neil explains. “Companies need to have a plan or be actively working towards one.” This approach focuses on Scopes 1 and 2 emissions, with encouragement to address Scope 3 emissions as well, paving the way for comprehensive decarbonisation strategies.The conversation then shifts to the concept of green heat. For Neil, “Green heat means any heat that doesn’t emit carbon emissions into the atmosphere.” He details sustainable heating options such as heat pumps, heat networks, and biomass heating, all of which provide alternatives to fossil-fuel-based heating. Paul and Neil delve into why green heat does not include electricity generated by solar PV or wind, since these power sources don’t directly heat buildings but rather generate electricity. Neil explains that heating is a substantial yet hidden emissions factor, consuming more energy than electricity, which makes decarbonising heat a top priority.Neil also shares his personal journey from accountancy to becoming an advocate for green heat and sustainable development. A significant topic covered is the affordability challenge faced by heat pumps in the UK due to the “spark spread,” or cost gap between gas and electricity. Neil compares the UK’s reliance on cheap North Sea gas to Denmark’s investment in heat networks following the 1970s oil crisis. He notes that this spark spread remains a barrier to the widespread adoption of heat pumps, but potential policy changes, such as the UK’s Review of Electricity Market Arrangements (REMA), could reduce this gap and support a clean energy transition.When discussing the practicalities of heat pumps, Neil provides insights from his personal experience installing one in his home. With the aid of solar panels, a battery, and the right electricity tariffs, Neil has managed to reduce his energy costs significantly. “My total energy bill has halved,” Neil reveals, highlighting the potential of combining renewable technologies with smart tariff management to maximise efficiency and savings. He emphasises that this approach not only saves money but also supports the transition to sustainable energy sources.In closing, Neil advocates for individuals and businesses to explore green heat options and net zero strategies. He underscores the urgent need to move beyond just renewable electricity toward a holistic approach that includes sustainable heating solutions. “By combining smart technology and a proactive mindset, we can all play a part in tackling the climate crisis,” Neil concludes.Key Guest Quotes“Climate is obviously very crucial to the future of the economy.
