ECO CLIPS

Tree Hugger - Wal-Mart Stores will be supplying 15% of the electricity in approximately 360 Texas stores and other facilities though wind power, purchased from Duke Energy. Wal-Mart says that the purchase will be the equivalent power of some 18,000 ordinary homes. Duke expects the project to produce about 226 million kilowatt-hours of electricity annually, an amount which will avoid emitting 139,000 tons of CO2. Wal-Mart compares this to washing 108 million loads of laundry.

Slashdot - Slow-moving ocean and river currents could be a new, reliable and affordable alternative energy source. A University of Michigan engineer, Michael Bernitsas, has made a machine that works like a fish to turn . . . vibrations in fluid flows into clean, renewable power. This is the first known device that could harness energy from most of the water currents around the globe because it works in flows moving slower than 2 knots (about 2.3 miles per hour). Most of the Earth's currents are slower than 3 knots. Turbines and water mills need an average of 5 or 6 knots to operate efficiently.
