Now we're into Gigawatt territory.
Renewable energy is already in the gigawatt realm.
Just keep adding to it each year and at some point you supplant the existing infrastructure.
Nope. Many efficiency improvements have already ocurred. faulty compounding math right off the bat. And again, the majority of energy use are not possibly replaced with electric conversion. Personal transportaion is the next easy one. But it is only 10% of total energy as I stated above. So cutting this consumption to 1/3 with electric conversion saves us 6%.
And.
Can we possibly build 60 kWh batteries for 1 billion electric cars?
