From the 50s to the 70s, we doubled our electricity about once per decade, so it’s not even greater than historical capabilities to do it in one or two decades.

From the 50s to the 70s, we doubled our electricity about once per decade, so it’s not even greater than historical capabilities to do it in one or two decades. As I showed above (sorry, I edited the post after you commented…), we’d need less land for solar than we currently use just for ethanol (which we don’t need). The calculations take longer than just a quick HN post, but it’s not hard if you just add up steel, fertilizer, plastics, gasoline (only takes about 10kWh of electricity to displace a gallon of gasoline), diesel, heating with 3COP heat pumps (higher is feasible, and northern climates should use ground source), etc.
