A Solar Grand Plan

>The cover story of this month’s Scientific American is a proposal to build out solar power in the US to supply 70% of the country’s electrical needs by 2050. It looks like a pretty doable plan, actually, requiring no technological advances in solar power beyond what’s projected between here and 2020. The price tag the authors estimate is $420 Billion, which works out to $10B a year, or about ½ of 1% of the US federal budget.
