(PhysOrg.com) -- New research has shown that it is possible and affordable for the world to achieve 100 percent renewable energy by 2030, if there is the political will to strive for this goal.
(PhysOrg.com) -- A wind-powered car has been clocked in the US traveling down wind faster than the wind. In a recent run at New Jerusalem in Tracy, California, the car reached a top speed of more than 2.85 times faster than ...
(Phys.org) —SheerWind Inc. of Chaska, Minnesota is claiming in a press release that its newly developed funnel-based wind turbine system is capable of producing 600 percent more power than conventional wind turbines. The ...
It's a balloon that lifts a wind turbine. That's the easiest way to describe the technology being developed by Altaeros Energies, led by Ben Glass, inventor and CEO of the young company. Glass has reimagined the possibilities ...

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.
