I wish people would consider the implications of their statements. I'm all in favor of sustainable energy but it must be founded on reality.
Quote from Al Gore's speech:
Scientists have confirmed that enough solar energy falls on the surface of the earth every 40 minutes to meet 100 percent of the entire world's energy needs for a full year. Tapping just a small portion of this solar energy could provide all of the electricity America uses.
A few details he forgot to mention
From an article in Scientific American, A Solar Grand Plan (http://www.scientificamerican.com/article.cfm?id=a-solar-grand-plan) — By Ken Zweibel, James Mason and Vasilis Fthenakis
The U.S. is lucky to be endowed with a vast resource; at least 250,000 square miles of land in the Southwest alone are suitable for constructing solar power plants, and that land receives more than 4,500 quadrillion British thermal units (Btu) of solar radiation a year. Converting only 2.5 percent of that radiation into electricity would match the nation's total energy consumption in 2006.
The technology is ready. On the following pages we present a grand plan that could provide 69 percent of the U.S.'s electricity and 35 percent of its total energy (which includes transportation) with solar power by 2050.
The federal government would have to invest more than $400 billion over the next 40 years to complete the 2050 plan.
Without subsidies, the solar grand plan is impossible.
Another quote from Al Gore's speech:
Enough wind power blows through the Midwest corridor every day to also meet 100 percent of US electricity demand. Geothermal energy, similarly, is capable of providing enormous supplies of electricity for America.
From an article in Wikipedia, Wind power in the United States
American wind farms will generate an estimated 48 billion kilowatt-hours (kWh) of wind energy in 2008, just over 1% of U.S. electricity supply.
Horse Hollow Wind Energy Center is the world's largest wind farm at 735.5 megawatt (MW) capacity. It consists of 291 GE Energy 1.5 MW wind turbines and 130 Siemens 2.3 MW wind turbines spread over nearly 47,000 acres (190 square km) of land in Taylor and Nolan County, Texas.
Some speculate that the extra CO2 humans release into the atmosphere will delay or prevent the next ice age from occurring. I am not advocating this view. See
