(Phys.org) —It's been a remarkable week for physics work—first a research team claims to have accurately 'teleported' quantum information ten feet, and report that they did so with 100 percent accuracy. If the claims ...
(Phys.org) —While previous research has shown that wind turbulence causes the power output of wind turbines to be intermittent, a new study has found that wind turbulence may have an even greater impact on power output ...
Over the past few decades, scientists have become increasingly aware of the adverse effects that human activities are having on the environment and climate on Earth. These environmental and climatic changes have several consequences, ...
Wind and solar farms are known to have local effects on heat, humidity and other factors that may be beneficial—or detrimental—to the regions in which they are situated. A new climate-modeling study finds that a massive ...

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.
