They're also much cheaper, per kilowatt hour of power they produce: A small wind farm in Colorado, United States.
A clear, easy-to-understand explanation of how wind power can be integrated into a grid network. How efficient is wind power? More to explore on our website...
How do wind turbines work? The first thing to bear in mind is that small wind turbines spin at dangerously high speeds, so technical skill and safety are paramount: A typical modern turbine has a maximum power output of about 2 megawatts MW , which is enough to run 1000 2kW electric toasters simultaneously—and enough to supply about 1000 homes , if it produces energy about 30 percent of the time.

In 2016 this figure stood at 11. The Guardian, 16 May 2018. Long-term patterns and relationship to electricity demand by Graham Sinden. Advantages On the plus side, wind turbines are clean and green: Last updated: Drawn by Explainthatstuff.
Photographs Need photos for a school project on wind power? Energy production 1—8 megawatts 1000—8000 kilowatts. This is largely dependent on wind speed and the type of turbine being used. Some manufacturers have pushed micro-wind technology aggressively, hinting that people could make big savings on electricity bills, and benefit the environment, by putting a little turbine on their roof to feed energy into the national power grid.
When the wind speed is faster, a braking mechanism automatically stops the wind turbine, ensuring the safety of the installation and minimizing wear. In short, while the growth of wind power is impressive, it still plays a relatively small part, overall, in providing the world's electricity. New jobs in construction, operation, and manufacture of turbines.
When there's lots of cheap electricity about at night or when the wind is blowing , water is pumped up the mountain to the high-level lake at low cost. Unlike fossil-fueled power, wind energy operating costs are predictable years in advance. The world's biggest offshore wind turbines can now make 6—8 megawatts, since winds are stronger and more persistent out at sea, and power about 6000 homes.
How does a wind turbine work? Ecotricity, the leading British wind energy company has a very informative website, with lots of photos and technical data about its turbines. Remember that roof-mounted wind turbines could prove noisy and cause problems with vibration.
