In 2006, total world wind generating electricity capacity was around 72,000 MW, producing some 160 terawatt-hours (TWh) per year of electricity. As of the end of 2006, the top wind producers were Germany, with 20,622 MW; Spain, with 11,615 MW; and the United States, with 11,575 MW.
Even so, wind accounts for only about 1 percent of the world’s total energy use. (more…)
Wind energy comes from the mismatched heating of the planet that runs all day and night, heated and cooled by the sun. They are also come as effect of the different between land and sea temperature, and natural barriers such as mountains. (more…)
As the name may suggest, a perpetual motion machine is a device used to provide cost free energy and if used well, it can be available for all human beings. Well, to begin with, it’s important to understand that it’s very difficult to understand, rather to conceptualize a perpetual motion machine because it can take decades to create it. Still on point, there are very many contradicting theories as to how one can come up with a perpetual motion (more…)
Wind energy alongside solar energy is one form of renewable energy and its supply is abundant in earth. Most people distinguish between wind energy and solar energy. However, this distinction is not necessary because wind that powers wind turbines is itself a form of solar power. It is implicated that wind energy source are from sun. Atmosphere heating by sunlight is the main caused of wind and its movement. Other factors like earth’s surface irregularities in shape and earth rotation also play role in wind formation and also consider as wind energy source.
