Because if you think about all the electricity oh god wind would not be enough and if by wind you meen wind things :P it is because first of all they are to much money and second ofall they are to large to fit in a backyard :p and you would need many
A windmill produced electricity while the wind blows. It may produce energy when the wind blows and people don't need it. People don't need all the energy a windmill produces all the time but they may need energy when the wind is not blowing. Windmills are therefore linked up to battery systems and charge the batteries when the wind is blowing, energy is being produced, and nobody is using it. When people need energy and the wind is not blowing (no power is being produced) they use power from the batteries.
the wind is in the gastronomical air so it is free any one can use it if there is a possibility that you can't use it is that there is no wind blowing or there is no breeze outside The approximate cost per KWH for wind energy is somewhere between six and seven cents. This is not really a good resource though because when the fossil fuels run out and we decide to use wind energy. We an also not be able to get wind all the time so that mens some of th time we will not be able to have electricity which is a very baad thing!
I would use both. One to blow wind for my wind energy
Wind
Windmills are a good way to use wind energy
Yes, many countries round the world use wind energy all the time. Several countries have achieved relatively high levels of wind power, such as 21% of electricity production in Denmark, 18% in Portugal, 16% in Spain, 14% in Ireland and 9% in Germany in 2010.
Wind energy.
Right now, Singapore does not use wind energy.
Windmills are not wind energy but if put in use it can create energy from the wind it gets so its called wind energy but all the energy is retained by the windmill... Easily enought "NO"
Wind energy
Yes its alternative is geothermal or wind energy
Well it is a good renewable source of energy BUT the strength of the wind varies over time and the source is therefore not constantly reliable.
