"...There is enough baseload solar potential in one 90-mile-by-90-mile grid in the American Southwest to power the whole country. A similar grid in North Africa could power all of Europe. India and China have equally large solar resources, more than enough to replace new coal.
And CSP is a decades old technology, that uses mostly commodity materials--steel, concrete and glass. The central component, a standard power system routinely used by the natural gas industry today, would create steam to turn a standard electric generator. Plants can be built rapidly, in two to three years. It would be straightforward to build CSP systems at whatever rate industry and governments needed, ultimately 50 to 100 gigawatts a year growth or more–if we got serious about global warming and technology deployment.
Once again, it is crystal clear “we can solve our energy problems with existing technologies today, without the need for breakthrough innovations."
