Re: Interesting idea
Very true. But it's also massively more flexible and extensible. Need more leccy? Add a few panels or an extra turbine of some sort. Or spend £30+ billion and wait 20 years for a new nuclear station
All well and good if you have both the money and roof space to add a few more panels, and are prepared to severely ration your consumption over the UK Winter (just when more electricity is needed). But it's probably less than 20% of the population who would even be able to do it, let alone those who would find it desirable.
But if you think it's so great, I am prepared to try it. I'll let you convince my landlord and the owner of the block of flats I live in to allow you to put PVs on the roof, and you can then pay to install them. In return you can have all the money I'll save from having them in perpetuity. Good deal? While you're at it, you can swap my petrol car for an EV and negotiate with my council to install a recharging point somewhere I am guaranteed to be able to park overnight. Again, you get to keep all the money I'll save (less the amount I have to spend on the occasional journey that's as yet impractical to do in an EV).
