Jeffrey Sachs, Director of the Earth Institute at Columbia University and author of Common Wealth: Economics for a Crowded Planet, was on Real Time with Bill Maher (h/t Crooks & Liars), and rather glibly pronounces:
...a small part of the Mohave Desert could provide more than half of the electricity needs of the United States without emitting any carbon dioxide, just using the solar power that's available...Yes, all of that solar energy is just going to waste, baking sand. And it would have absolutely no effect on the climate whatsoever to begin diverting that energy to the vastly more important work of transportation and artificial climate control.
We humans clearly have a vast amount of humble pie to consume before we find our proper place on this planet. Need you add crow to the menu, sir?
