Wind systems also consume fossil fuels when the wind is above the safe operation limit by placing power on the generators to prevent the blades from turning. They also consume power for a few minutes while starting to get the blades to the correct speed and sync with the grid. Additionally...

geothermal energy can be extracted without burning a fossil fuel such as coal, gas, or oil. Geothermal fields produce only about one-sixth of the carbon dioxide that a relatively clean natural-gas-fueled power plant produces. Binary plants release essentially no emissions. Unlike solar and wind...

the wind energy industry is booming. Globally, generation more than quadrupled between 2000 and 2006. At the end of last year, global capacity was more than 70,000 megawatts. In the energy-hungry United States, a single megawatt is enough electricity to power about 250 homes.

Cut your electricity bills: wind is free, so once you've paid for the initial installation your electricity costs will be reduced. Get paid for what you generate: through Feed-in-Tariffs, you get paid for the electricity you generate even if you use it. What you don't use, you can export to the...

To make a homemade wind turbine, you are going to need several things. Youre going to need a strong roof or structure that can support the blades of the device, a connection that attaches to the generator, the tail assembly that ensures that unit will stay facing the wind and other various...

A self-sustaining power module that combines the technologies of radioactivity with photovoltaic cells to produce an electrical power supply having a useful life of over ten years. The radioactive source is a tritium capsule that interfaces with the receptor surface of the photovoltaic cell.The...

New research finds that wind farms actually warm up the surface of the land underneath them during the night, a phenomena that could put a damper on efforts to expand wind energy as a green energy solution.Even more of a reason to look at Solar as being the most viable, that is, for now. But...

A wind turbine is a device that converts kinetic energy from the wind, also called wind energy, into mechanical energy; a process known as wind power.Small wind turbines may be used for a variety of applications including on- or off-grid residences, telecom towers, offshore platforms, rural...
