Maglev Wind Turbine Levitating

Designers in China have launched the first wind turbine levitating in the world of permanent magnetic levitation (Maglev) in the Wind Power Asia Exhibition 2006.

Considered a key step in the evolution of global wind power technology and a notable advance in independent intellectual property rights in China. The generator was jointly developed by the Institute of Energy Research of Guangzhou in the Chinese Academy of Sciences and Guangzhou Hengyuan Energy Science & Zhongke Technology Co., Ltd. (more…)

Coal Overcomes Wind Power: Marks Annual Record Electric Generation

Power consumption from electricity is an essential element of the U.S. economy since the beginning of the century. Coal power plants, a power source of electricity are available to deliver large quantities of low cost and reliable power supply. It has become more important than the supply of petroleum and natural gas, as the latter supply is decreasing over the time. In 1995, the burning of coal produces about 55% of the electricity produced in the U.S. We also know that coal reserves are expected to last for centuries at current use. (more…)

The German Wind Power Program

Germany is considered a world leader in wind energy deployment, with electricity production from wind having gone up more than eightfold—from 670 to more than 5500 GWh—between 1993 and 1999. In 1999, Germany had more than 4000 MW installed capacity. The prices also declined substantially over this period, indicating a learning rate of approximately 8%, and it is estimated that for each deutschemark (DM) spent by the government in subsidizing learning, market actors provided 2.1 DM. Furthermore, the manufacturing base for wind energy technologies, including indigenous firms as well as joint ventures, continues to expand in Germany. (more…)

Small Wind Turbines for Home - Market Potential

small wind turbines
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…)

Wind Energy Industry Growth Forecast in United States and EU

wind energy industry growth
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…)

Taking Benefits of Wind Energy Electricity

benefits of wind energy electricity
Wind energy comes from the mismatched heating system 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 heat temperature, and natural barriers such as mountains. (more…)

Wind Turbines For Private Homes

wind turbines homes
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…)

Design of a Wind Turbine Controller for Power System Stabilization

wind-turbine-controller
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…)

How Does Wind Energy Works and Conversion to Electricity

how wind energy works
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.

What causes wind flows?
