From Bill Andrews, Maxworthy, Cornwall, UK
I enjoyed the article on home heating and climate change, as someone who fitted a ground-source heat pump to my home well before the UK's Renewable Heat Incentive or any other renewable energy subsidies were developed. You note that UK peak demand for heat energy in the winter is six times higher than that for electricity, implying that much heat demand cannot be met by electricity from renewables.
But if, for example, all heat energy were supplied by heat pumps producing five times as much heat energy as they use in electrical energy, this difference would be lower. This would indicate the full benefit of using heat pumps – provided we drive them from renewable sources.
