At the moment the US produces a bit more than 2 000 000 GWh of power from coal fired power plants. If there is any serious thought to reducing CO2 emissions, then these plants need to be replaced.
If this is to be done over 20 years, this 100 000 GWh of new green energy each and every year. This means we need 30 Bute Inlet projects each year for 20 years just to replace US existing coal fired power.
I have not considered Canadian coal or and oil and gas power production.
BC can go a long way toward providing that power. 400 000 GWhs of green power over the next 20 years is possible here in BC. 800 000 is in theory possible. And this is all green power.
