Renewable energy OK, but not too close to home

When it comes to transitioning from carbon-based to renewable source energy systems, Americans are on board. They're less keen, however, having these new energy infrastructures—wind turbines or solar farms—built close ...

Steering wind turbines creates greater energy potential

As wind passes through a turbine, it creates a wake that decreases the downstream average wind velocity. The faster the spin of the turbine blades relative to the wind speed, the greater the impact on the downstream wake ...

How to build a better wind farm

Location, location, location—when it comes to the placement of wind turbines, the old real estate adage applies, according to new research published in Proceedings of the National Academy of Sciences by Carnegie's Enrico ...

Are wind farms slowing each other down?

The expansion of wind energy in the German Bight and the Baltic Sea has accelerated enormously in recent years. The first systems went into operation in 2008. Today, wind turbines with an output of around 8,000 megawatts ...

US to open California coast to wind power

The US government is set to open California's Pacific coast to offshore wind farms, officials announced Tuesday, adding to the approval of the nation's biggest wind project to date off Massachusetts.

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.
