Irving. Correct my logic.
UK gov wants to dump all petrol and deisel cars. And all gas powered everything, including central heating. With gas boilers, fossil cars (and busses, trucks, boats like container ships etc) in the next 2 decades. Buses in 4 years...
So my figures all fro gov own websites.
Average houshold kwh electrical use 12kwh.
Average houshold gas in kwh for heating 76. (non in summer and 2x 76 in winter)
Average EV power needed daily? Unknown. But a small EV has 70kwh battery. Some teslas have 90, to 200. The new sportster has 300. The tesla truck estimated 350. Lets say we need a 50kwh top up per day.
Average houshold has 1.6 cars. Not including business vehicles, vans or trucks.
Right now we struggle to provide adequate electrical power power in the UK, after shutting down many of the cheap coal stations. As I looked the other day at 8pm in the evening, on a live site, where theres was little wind, 61% of our energy was from natural gas (turbine). 6% from coal (still being shut down!) 11% from nuclear with some being shut down soon. With just 3% from wind. 0% from solar since it is winter and dark. Around 12% from undersea cables, from ireland, belgium, france and holland. Some negligible other sources add up for the difference such as water and biofuel. (wood from the USA!)
So... We are about to dump gas. And coal. So that night we would be short of 61 and 6% (67%) of our energy...
And now instead of 12kwh average electricity needs at every house across the UK. We need:
12kwh+
76 + 76kwh (twice because its not used in summer!)+
Whatever electric cars need? Say 50kw x 1.6 for number of cars per household. So 80kwh
76+76 heat,+80 car(s)+ original 12kwh of today = 244kwh
Even if ALL of my esimates are wrong by DOUBLE too high, and they are not then thats 122kwh per house! Thats a TEN FOLD increase in power requirements from the already incapable grid. The grid cant cope now. And thats WITH gas and still some coal. So tell me how is that going to work?
And remember that this includes container ships, trucks, business vehicles, industry, farming, and busses and coaches, ferries, etc that isnt even added in!
Not only are these polititions and greenies not realistic, but its simply not possible regardless of cost.
