Building a better turbine

Imagine a world in which half of our electricity is generated renewably by offshore wind farms. Now imagine a powerful hurricane hitting the coast where that farm is located. If developers, engineers and policy makers haven't ...

The complicated future of offshore wind power in the US

Over the past decade, wind power production in the U.S. has tripled, becoming the largest source of renewable energy in the country, the American Wind Energy Association has reported. There are more than 56,800 wind turbines ...

Improved hybrid models for multi-step wind speed forecasting

To mitigate global warming by reducing emissions, wind is widely expected to become an alternative source of energy. Wind power generation uses the surface atmosphere, where movement blows the wind turbine to generate the ...

A self-healing composite

Researchers from EPFL's Laboratory for Processing of Advanced Composites have developed a material that can easily heal after being damaged. This cutting-edge composite could be used in aircraft, wind turbines, cars and sports ...

Perceptions play big role in how residents feel about wind energy

When local residents feel the planning process for building wind turbines is fair and open, their perceptions of the often-controversial energy source remain steady or improve with time, according to a University of Michigan ...

Researchers synthesize renewable oils for use in lubricants

Engine gears, plane thrusters, refrigerator compressors, wind turbines—the list of important industrial machinery, agricultural equipment, transportation vessels, and home applications that depend on lubricants might be ...

Wind turbine

A wind turbine is a rotating machine which converts the kinetic energy in wind into mechanical energy. If the mechanical energy is used directly by machinery, such as a pump or grinding stones, the machine is usually called a windmill. If the mechanical energy is then converted to electricity, the machine is called a wind generator, wind power unit (WPU), or wind energy converter (WEC).

This article discusses electric power generation machinery. The windmill article discusses machines used for grain-grinding, water pumping, etc. The article on wind power describes turbine placement, economics and public concerns. The wind energy section of that article describes the distribution of wind energy over time, and how that affects wind-turbine design.
