Fascinating, thank you for sharing.<p>As I write this, it appears that the UK grid is running around 30GW, of which about 55% comes from local fossil fuels, 29% nuclear, nearly 10% imported from France and Holland, and a mere 5% or so from the major (non-nuclear) renewable sources.<p>There is an interesting note that coal (only 15% right now) is still the largest contributor to the UK grid overall, but used more in winter because running hours are restricted for environmental reasons so they do more in winter when it's more profitable.<p>I am surprised (and, honestly, disappointed) to see that so little of the total is still drawn from clean, renewable sources after all the concern about both fossil fuel supplies and environmental effects in recent years. Having just been on holiday to a country not a million miles away where they have essentially no native fossil fuels and so almost everything is run on relatively clean renewables, it's clear that we still have a long way to go.
