>Since the sun doesn't shine all the time and you don't get peak output all the time 750 square meters per person doesn't seem terribly unrealistic.

At current prices, that much PV capacity would cost around 25 trillion dollars. That price doesn't include any storage capacity.

The climate is changing far too rapidly for us to hope for science fiction solutions. We need a major reduction in emissions now, which means both a vast increase in renewable production and a vast reduction in overall consumption.

You only need a third of that to get the same amount of electricity out of them as by burning 10 kW of fossil fuels. Spread over 20 to 30 years that's suddenly not so much anymore. How much does the US spend on energy each year now? How much to secure the imports?
