In the UK the sun does not shine all the time, it is sporadic. The amount of fields needed to be covered in solar panels to net any decent power would mean there would be none left for food production.
The wind does not blow all the time either, every day I pass 4 massive turbines on the way to work, very often they are not turning. I am also led to believe that the turbines cannot sit idle for long and have to be turned to stop bearing issues developing therefore
using power.
We have a nuclear power station on the coast, Sizewell A and B reactors, which are ageing. Sizewell C is planned, but is years away.
OK so if you manage to sort the supply then the delivery infrastructure wont cope. I live in the sticks, if 10 people plugged in their cars to charge then the overhead supply would simply not deal with it.
Its not easy. The rush to electric vehicles is not at all well thought through and sales are already plummeting as owners realise the pitfalls.
I can see power outages and rationing in our futures, the push for smart meters will allow the suppliers to turn off neighbourhoods at will to eek out supplies.
Its not easy being green
