The MOD-2 wind turbine cluster of three turbines produced 7.5 megawatts of power in 1981. In 1987, the MOD-5B was the largest single wind turbine operating in the world with a rotor diameter of nearly 100 meters and a rated power of 3.2 megawatts. It demonstrated an availability of 95 percent, an unparalleled level for a new first-unit wind ...
Wind turbines are an increasingly important source of intermittent renewable energy, and are used in many countries to lower energy costs and reduce reliance on fossil fuels. One study claimed that, as of 2009, [update] wind had the "lowest relative greenhouse gas emissions, the least water consumption demands and the most favorable social ...
Wind power is considered a sustainable, renewable energy source, and has a much smaller impact on the environment compared to burning fossil fuels. Wind power is variable, so it needs energy storage or other dispatchable generation energy sources to attain a reliable supply of electricity. Land-based (onshore) wind farms have a greater visual ...
Wind energy was among the renewable energy options incorporated in energy policy beginning in the 1970s and continuing into the present day. The growth in wind energy can largely be accredited to the public policy's providing incentives and technological advances, making wind energy one of the few cost competitive renewable energy options.

Since Iowa adopted a renewable energy standard in 1983, the wind power industry has generated over $19 billion in investment. [76] The second concrete wind turbine tower to be built in the U.S., and also the country's tallest (377 feet) at the time built, is in Adams county. The tower was completed in the spring of 2016.

Morocco has undertaken a vast wind energy program, to support the development of renewable energy and energy efficiency in the country. The Moroccan Integrated Wind Energy Project, spanning over a period of 10 years with a total investment estimated at $3.25 billion, will enable the country to bring the installed capacity, from wind energy ...
Some residents who live near the turbine have complained of its allegedly loud noises and a “shadow flicker.” They even filed suit. What to know about the complicated history behind the ...
The 845-megawatt Shepherds Flat Wind Farm in Oregon is the first windpark in the United States to utilize permanent magnet design in its primary wind turbine. Fântânele-Cogealac Wind Farm in Romania, constructed in 2008, uses 240 GE 2.5xl wind turbines capable of generating a total of 600 MW, powering a million Romanian households each year. [29]
