Humanity has been harvesting energy from the wind for centuries. The practice goes back at least to 8th century Persia where the first known historical records of windmills came, but likely extends ...

What is wind power density? The different types of generators used in wind-turbine systems. What architecture is most commonly used in high-power wind-energy-conversion systems (WECS)? Fundamental ...

A design firm from New York, Atelier DNA, has developed a concept that uses cattail like stalks instead of traditional turbine blades for harnessing the power of wind. Planned for the city of Masdar, ...

Norway's World Wide Wind has a radically different take on offshore wind power. These floating, vertical-axis wind turbines feature two sets of blades, tuned to contra-rotate – and they promise more ...

People interested in reducing their carbon footprint, along with their monthly energy costs, have an array of options to consider. One of them is wind power. If you've narrowed down your options and ...

When most of today’s wind projects were developed, first costs were the focus; operations and maintenance (O&M) costs were largely unknown. Now, with hundreds of turbine models in operation—sometimes ...

While wind energy is rapidly increasing its market share across the world, wind turbines are not able to be constructed everywhere that they might be needed. A perfect example of this is Japan, where ...

Each turbine in a wind farm is equipped with a step-up transformer, which boosts (steps up) turbine generator output voltage from a few hundred volts to the collector system’s medium voltage ...

James Dyson and the team at the James Dyson Foundation announced today the winner of the 2018 Dyson Award, selecting a small, omnidirectional wind turbine out of 20 international finalists. Called ...
