This site shows the UK’s power generation breakdown. At the time of writing, our 30GW demand is created by natural gas (55%), nuclear (20%), wind (11%) and other (14%). Sustainable and clean energy, for all the PR I see, isn’t quite the player I thought it’d be by now.
Though we sometimes focus on the carbon intensity of electricity, what I think might matter more, is the amount of greenhouse gases released to the atmosphere from power generation. 2019 emissions from energy supply was 65.5% lower than they were in 1990.

Energy itself isn’t evil. It’s necessary…to create food, pump water, generate warmth, charge your phone, play Netflix. Energy security isn’t inherently bad. Sustainable methods are better for many reasons, but its current capacity can’t provide all our energy needs. Much work needs to be done to build out the infrastructure.
