In 2001, there were 14,000 small wind turbines for home/domestic use in the United States. The market potential for national and international market for small wind turbines is growing and have bright prospect. Small wind turbines as producing small energy are having the capacity up to 8% of the electricity needs of the United States in 2020. (more…)
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…)
Wind is a natural and inexhaustible source of energy, wind does not have to be imported or mined from deep down the earth. Wind energy is free from fuel price roller coaster and politics. Is it possible to build wind turbines for private houses so that you utilize wind energy and get your own electricity for your household needs? The answer is yes. (more…)
In many countries of the world wind power expands and covers a steadily increasing part of these countries’ power demand. Growing wind power has impacts on the power systems into which the wind turbines feed their power. As wind power penetration increases, the respective power system operators are concerned about the stability and reliability of their power systems. Therefore, more and more power system operators revise their gird connection requirements and issue grid connection requirements specifically made for wind turbines and wind farms. (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.
