[ad] A complete Wind Turbine Glossary listing all major parts and components of an industrial wind turbine.     Anemometer: Measures the wind speed and transmits wind speed data to the controller.    Blades: Most turbines have either two or three blades. Wind blowing over the blades causes the blades to "lift" and rotate. Brake: A disc brake which can be applied mechanically, electrically, or hydraulically to stop the rotor in emergencies. Controller: The controller starts up the machine at wind speeds of about 8 to ... Read More

[ad] Denmark's Vestas, the world's largest wind turbine maker, is enjoying a large number of orders recently to come back from a very shaky 2009. Vestas announced last Wednesday that German company Nordwind Handels GmbH & Co. ordered 40 V90 turbines for installation in eastern Germany. Each turbine has a capacity of 2 MW. The contract includes delivery, installation and commissioning as well as a 10-year service agreement, the company said. "Installation of the turbines will start during the fourth quarter of 2010 and the project ... Read More

[ad] By Poornima Gupta - SAN FRANCISCO, Nov 17 (Reuters) - Technology giant Intel Corporation is seeing big opportunities in wind forecasting for power generation, and in information management for electric vehicles, John Skinner, Intel's director of marketing for its Eco-Technology division said on Tuesday. Intel already sells microprocessors to wind turbine manufacturers and this would be an expansion of that business. Adoption of wide-scale wind power would rely on accurate forecasting, such as when the wind would blow and how fast, he said. "There's a lot ... Read More

[ad] ALTERNATIVE ENERGY - OCEAN THERMAL ENERGY – THE FACTS – A process called Ocean Thermal Energy Conversion (OTEC) uses the heat energy stored in the Earth's oceans to generate electricity. OTEC works best when the temperature difference between the warmer, top layer of the ocean and the colder, deep ocean water is about 20°C (36°F). These conditions exist in tropical coastal areas, roughly between the Tropic of Capricorn and the Tropic of Cancer. To bring the cold water to the surface, OTEC plants require ... Read More

    [ad] By Camille Ricketts - Engineering giant Siemens has made its presence felt in the wind business, winning six contracts to build 565-megawatts worth of wind turbines, valued at more than $900 million. About 250 of the turbines will be installed in Ontario Canada, with the other 750 (enough to power 170,000 homes) destined for wind farms in California, Oklahoma, Washington and Wyoming (for a project owned and operated by Duke Energy). Having first entered the wind market five years ago, Siemens is steadily climbing ... Read More

[ad] Danish wind manufacturer Vestas is planning to invest  $380m in Gujarat, Kutch - India. The world's number one wind power solutions provider Vestas is increasing its installed capacity in Gujarat after the third largest wind turbine manufacturer in the world, Suzlon Energy, has already decided to expand the capacity of its wind farm in Kutch. Vestas has already got a wind power generation capacity of 60 Mw in Gujarat. "Vestas is planning to install another 250 Mw capacity in Kutch in the next one ... Read More

[ad] World Wind Maps - Wind Atlases of the World. This article provides you with essential links to world wide wind maps. The maps contain data on the wind speed and wind direction in a region. Typically, a climatological wind atlas covers hourly averages at a standard height (10 meter) over even longer periods (30 years). You can make use of a wind atlas when you are looking into pre-selecting wind farm sites. The wind atlas methodology and has been applied in more than 100 countries and territories around the ... Read More

[ad] Ocean wave energy is captured directly from surface waves or from pressure fluctuations below the surface. Waves are caused by the wind blowing over the surface of the ocean. In many areas of the world, the wind blows with enough consistency and force to provide continuous waves. There is tremendous energy in the ocean waves. Wave power devices extract energy directly from the surface motion of ocean waves or from pressure fluctuations below the surface.  Wave power varies considerably in different parts of ... Read More

This article shows a high quality video animation explaining in an easy to understand demonstration and language how wind power actually works. Great and usefull high level information for the excited newcomer to wind power. [ad] 1.) Modern wind turbines start generating electricity at a wind speed of approximately 9mph. As wind speed increases so does electrical output. At storm force over 55mph, they cut out to prevent damage to the turbine 2.) A Yaw Drive turns the turbine to face directly into the wind. ...

Alternative Energy - SOLAR POWER (solar panels) [ad] Solar energy is one the most resourceful sources of energy for the future. One of the reasons for this is that the total energy we receive each year from the sun is around 35,000 times the total energy used by man. However, about 1/3 of this energy is either absorbed by the outer atmosphere or reflected back into space (a process called Albedo). Solar energy is presently being used on a smaller scale in furnaces for homes ... Read More

WIND POWER Wind power is another alternative energy source that could be used without producing by-products that are harmful to nature. Like solar power, harnessing the wind is highly dependent upon weather and location. The average wind velocity of Earth is around 9 m/sec. Wind turbines are used to harness the wind. The diagram below shows a simplified version how a wind turbine converts the kinetic energy in the wind to electrical energy around the country. 1. The wind blows on the blades and makes ... Read More
