Wind is a form of solar energy. The irregular heating Earth's atmosphere by the Sun causes the air mass to move from regions of high pressure to lower pressure areas. The kinetic energy of the moving air (wind energy) can be translated directly into...

Viewpoint: Yes, wind power is already the fastest-growing source of renewable energy in the world, and economic trends, technological advances, and environmental concerns will eventually transform it into a large-scale contributor of energy. Viewpoint:...

The ultimate source of most energy used by humans is the sun. Fossil fuels, for example, are substances in which solar energy has been converted and stored as plants or animals that have died and decayed. When energy experts look for alternative...

Wind power is the conversion of wind energy into useful form, such as electricity, using wind turbines. In windmills, wind energy is directly used to crush grain or to pump water. At the end of 2006,...

NYSTED, Denmark IN THE EARLY 1970s, before Chernobyl or Three Mile Island, before anyone was worried about climate change, the Danes decided to harness the wind and not the atom to generate much of their electricity. Today, the design and production of state-of-the- art...

TEACHING NOTES (TN) Dear Subscriber, In this issue, we explore the power of the wind to help your students understand that forces in their world are not always visible. We need to examine the effects of the wind and use our...

An orange flag marks where Gary Lisle planned to put up a 33-foot windmill behind his house. But that's about as far as his green idea got in this Dallas suburb.Denied a building permit in March, Lisle joined the growing ranks of frustrated homeowners across...

After a century and a half as cordial neighbors, two of the nation's biggest ranches find themselves feuding like the Hatfields and McCoys over wind energy and wildlife and whether the two can coexist.The storied King and Kenedy ranches, which together cover nearly 1.3 million...

Cape Wind, a proposed $700 million dollar project, would involve the construction of wind turbines offshore from Cape Cod, Massachusetts, on Nantucket Sound. Such turbines would, in turn, serve as an alternative energy source and a renewable, unextinguishable source of energy. However, the project's benefits do not measure up against the negative impact it would have on the area's ecosystem, its fishing industry, and its scenic views.

Windfarms are a clean and economical way of harnessing energy. The issue isn't the quality or avaialibility of power, but rather, at what cost. These high windmiils are considered eyesores to prestine coastal landscape and are being challenged in Australia by vacationers, cottagers and the costal community.

Since 2004, wind power has become the least expensive alternative energy source to fossil fuels. Wind power is also growing quickly and becoming a practical replacement for fossil fuels because it is unlimited, clean, efficient and does not produce any byproduct.
