Sorry to use coarse language, but that point about prices going up because of less units being sold is generally incorrect. The wholesale price of electricity has fluctuated in recent years but isn’t significantly different now to what it was 10 years ago (in fact, in 2008 there was a period when wholesale prices went crazy). Actually, on windy or sunny days, particularly in summer, the wholesale price goes down and is occasionally negative - i.e. generators are having to pay to put their energy onto the grid. What has changed with the advent of renewables in the UK is that of your price of domestic electricity of (say) 15p per kWh, about 4p is being paid by your supplier and is ending up going as subsidy for wind farms and solar panels which were installed when subsidies were much higher than they are now. More money is also being spent on balancing the electricity system (as AC can’t be stored), transporting electricity from a larger number of wind farms around the grid, plus paying owners of coal and gas power stations to keep their plants ready to run for the smaller amounts of time when they are really needed. This latter part is done in a competitive auction process and plenty of assets have already closed. Coal and gas stations have to pay two different carbon taxes already. For what it’s worth, despite the change in the make-up of the price of electricity to the end consumer (and the general increase in levies and subsidies) prices in the UK remain much lower than in most of Europe. From memory, I think we are about the 12th cheapest out of the EU 15. German domestic electricity is about 30 cents per kWh; the big difference is that they are making a better job of building efficient houses - standard build when I last saw a German building site was 300mm cavity filled with polystyrene blocks. As such, we use more electricity and have higher bills, despite it being cheaper per unit. And will continue to do so, until we get more efficient.
