So, where is all the electricity going to come from to power all these electric car batteries?
Hydro power (no more rivers to dam)
Natural Gas (fracking is bad)
Coal (bad CO2)
Nuclear(not in my backyard)
wind (high upkeep)
solar (10% efficiency)
Biomass/wood burning pellets(cutting trees)
All of the above contribute to our current power grid. Some of the above are going up in percentage, some are going down. Solar is going to have to become much more efficient to increase its contribution. Can the grid handle the additional load of millions of people charging their autos
at home? Probably not currently.
You may be correct in that battery technology will improve greatly in the coming years. However, where is all the power going to come from to charge these batteries?
We're changing over to renewable energy. That means we can take the old electricity and make new electricity out of it.
Problem solved.
