Re: Buy stock in bullshit makers Now!
Ok, trying to be serious for a monent (yes I know it hurts some around here)
1) Every house has PV cells on the roof. Especially new builds and all housing Assoc properties. Quite why new builds don't have them already is beyond me.
2) Every house has storage batteries (think cheap Tesla Power Wall).
3) Where appropriate Ground source heat pumps can be used to heat/cool the house.
Then the batteries can charge during the daytime either from the PV or the mains. Then when it is dark the house can be powered off the battery. so if there are 'Brown Outs' homes can continue watching Corrie/EastEnders. That will keep the masses happy.
It can be done using current tech if you have the will. Yes it costs a lot at the moment but look at the size of the battery factory that Elon Musk is building near Reno, Nevada. That alone in its current form will produce 50GW of storage a year. Not all of that will go in Tesla's.
If you go to Brazil, even very poor homes in the shanty towns have PV cells on the roof. Yes they are small but they allow the family to have light at night. all it takes is the will.
I fully expect this to attract a fistful of downvotes. If you do please take the trouble to explain why. Then perhaps we can learn from your great wisdom.
