Wind Power
Wind power is derived from the conversion of wind energy to become a useful form of energy to propel ships, make electricity or pump water. Wind is a renewable source of energy that is widely available and produces no harmful emission during operation.

i'm not very sure, but i know it has magnets. as for zinc, you will have to see if someone else answers it. Yeah...;.
How is hydroelectric power an indirect form of solar energy?
Because solar energy runs the water cycle, giving rise to precipitation, and then the rain water flows into the reservoirs of dams.
How many wind turbines are there in Britain?
The number on onshore wind turbines in Britain has reached 30,000. This was after increasing . by 13 per cent last year.
If mwatt stands for milliwatts, then there are 0.000001 kilowatts (kW) in 1 milliwatt (mW). There are 1000 kilowatts in 1 megawatt (MW). To make these conversions, you can use the meaning of the prefixes kilo-, milli-, and mega-. While the prefix kilo- represents 1000, milli- stands for one thousandth and mega- denotes one million.
No, wind is useful for powering wind turbines (to produce electricity). It is also used for moving sailing ships and yachts, for drying clothes, for turning windmills to grind corn, pump water and cut wood. It is not used for heating.
Disadvantages when a hydroelectric power station is near a waterfall?
1. Finding new suitable sites can be difficult.
2. In times of drought water supplies can be reduced drastically thereby reducing the amount of electricity that can be generated.
Where are wind farms sited at the moment?
The majority of wind farms are currently placed an high lands or offshore
How does biofuel use differ from solar wind and geothermal energy use?
Biofuel has to be burnt. The heat is used to produce steam which turns electricity turbines, in much the same way as fossil fuels (coal, oil and natural gas) power stations. This burning releases carbon dioxide, but this is a recent recycling of the gas, with no carbon footprint.
None of the other three Is burnt.
* Solar uses photovoltaic panels or focussing mirrors.
* Wind uses the motion of the wind, like hydro power.
* Geothermal uses the existing heat from under the earth to produce the steam.
Supporters of nuclear energy hailed it as a cleaner and less expensive alternative to?
Fossil fuel. It is cleaner, even considering the risk of contamination. Even fossil fuel plants produce radioactivity, something that many people either don't know, miss, or deliberately ignore. Add environmental issues to that, and nuclear energy comes out the big winner, when you look objectively at the big picture.
As far as less expensive, well, that is subject to debate. Certainly, given the current costs of design and construction, even before Fukushima Daiichi, nuclear energy was more expensive in the short and mid term. In the long term, however, it is still less expensive, in my humble opinion.
Its a natural renewable resource and also is very much or non-polluting and is avialable in allmost all parts of the world with different rate so is consider as cheap and effective power source
