Sheer Bundles of Energy
By: Ruel Hinaloc, Tue Sep 18th, 2007
Remarkable speeds of 53 miles per hour (85 km/h) in normal flight, with peaks of over 71 miles per hour (114 km/h), have been measured. Migratory species are even more surprising, for they cover tremendous distances. Of the three North American hummingbirds, ruby-throat and rufous migrate some 2,000 miles (3,200 km) to their winter quarters. The broadtailed hummingbird flies from southern Mexico to the Rockies of Colorado and Wyoming, a distance of 1,500 to 2,000 miles (2,400 to 3,200 km). Now, think of its mere three inches (7.5 cm) and you have reason to wonder how such a small creature can do it.

When You Should Choose Wind Turbines Over Solar Panels
By: James Bratley, Tue Mar 6th, 2007
Many people today are unaware of why and when you should use renewable energy sources in today’s world. The main reason for using natural energy is mainly down to the environment, and if you care to improve the quality of it. But with many viable energy sources out there, which one you choose can be a nightmare to decide upon.
