October 20, 2008 High prices for gasoline and home heating oil are here to stay. The U.S. is at war in the Middle East at least in part to protect its foreign oil interests. And as China, India and other nations rapidly increase their demand for fossil fuels, future fighting over energy looms large. In the meantime, power plants that burn coal, oil and natural gas, as well as vehicles everywhere, continue to pour millions of tons of pollutants and greenhouse gases into the atmosphere annually, threatening the planet.

These steps power plants could supply 69 percent are not enough. The U.S. needs a bold plan of the U.S.s electricity and 35 percent to free itself from fossil fuels.

A Solar Grand Plan: Scientific American power is the logical answer. have to be erected in the Southwest.

Excess daytime energy would be stored as compressed air in underground caverns to be tapped during nighttime hours.

Large solar concentrator power plants would be built as well.

A new direct-current power transmission backbone would deliver solar electricity across the country.

But $420 billion in subsidies from 2011 to 2050 would be required to fund the infrastructure and make it cost-competitive.
