Solar and wind energy on Earth certainly are economically viable, far more than the costs and damages we'll have to pay for massive climate change. Fossil fuels are "cheap" right now only because the costs (military action, increased pollution and disease and medical costs, climate change, wildfires, crop losses) are paid for through circuitous routes, or are not being paid yet (read: borrowed/stolen from future generations), or the costs and damages are forced onto disenfranchised people in poor countries who have no recourse to the people making these decisions. We literally can't afford to keep paying for that crap.
Solar energy beamed down from outer space? I don't know anything about that. ~Ellen ---------------------------------------- > Date: Wed, 4 Sep 2013 17:40:15 -0300 > Subject: Re: For David Brin and the rest of you > > Even if these things were economically viable (which they probably > ain't), ambientally it would be a disaster.
