UK's 'illegal' backup power scheme subsidised fossil fuels - a greener alternative should now replace it

The amount of renewable, low-carbon, energy the UK produces is increasing, but it is very different to traditional types of power. It can't just be turned on when wanted. As a result, the capacity market scheme - essentially a programme of subsidies - was set up to help provide backup power when the supply of renewable energy the UK produces is outpaced by demand.
