On April 26, the Tucson Solar Potluck will be held in the desert north of Tucson. It is the 32nd straight year for the gathering of solar enthusiasts, a streak that some believe qualifies it as the longest continuously held solar event in the U.S.
Renewable Energy: An Overview - Wind
Wind is often considered an indirect form of solar energy because wind currents are created when the sun unequally heats different areas of the Earth's atmosphere. It is renewable because the wind blows. In one 24-hour period, the wind blowing across the U.S. offers almost 14 times the energy used by the entire country. The problem arises in capturing that energy and putting it to use.
The potential for the commercialization of wind power in Arizona is limited because the average wind speed is between 7 and 10 miles per hour. Wind speeds above 14 m.p.h. are required before utility-grade windmills are feasible.
