For several thousand years now, man has known how to extract energy from the wind by means of ships, sails or wind wheels. Wind energy is attractive for many reasons. Like Biofuels and Solar energy, it produces no health-damaging air pollution, forest-destroying acid rain, climate-destabilising carbon emissions, or dangerous radioactive waste.

Wind Energy Basics. Wind, as the primary energy source, costs nothing and can be used decentrally. There is no need for an extensive infrastructure such as that required for a power supply network or for the supply of oil or natural gas. Read about history, technologies, turbines, impacts and dimensioning. .....more.

"The Grid". The Electricity Grid ("The Grid") in a country is potentially one of the most important tools in building fossil energy independence and the use of alternative energy sources. "The Grid" connects and distribute to the consumers and anyone of them can also be a potential energy supplier, without any technical modifications. .....more.

Plug-ín Wind turbine, development specification. Large wind turbine technology is already one of the larger future energy supplies and small wind turbines have a big potential. What is needed for a common use of wind are turbines that meet a specification that is flexible enough for general application and be possible to mount almost everywhere.. .....more.

Practical Wind Generated Electricity. Several technologies have existed for a number of years that use the power that is present in wind movements to create electric power. In general, the wind movement causes some sort of rotary motion. In virtually all practical devices, this rotation occurs at a rather low rate. Most devices therefore use some sort of gear train to get a rotation rate that is fast enough for electrical alternators. .....more.

Germany Leads in Alternative Energy. Clusters of tall white wind turbines spin gracefully atop green hillsides. Solar photovoltaics (PVs) are integrated into windows and rooftops of modern homes, factories and office blocks. Even the old renovated seat of government is fitted with solar panels. .....more.
