Why can't all houses have a small wind generator to feed back electricity into the grid .?
Answer:
Well, there'd be no point feeding the power back into the grid as there wouldn't be enough power being created to meet the demands of the household, but it would certainly do the world a lot of good.
Because the pure sign-wave converters cost more than what the wind generator will put out in 10 years :)
This has to do with the fact that not all areas have an average wind speed year round to produce enough electricity to cover the cost of the generator.
If you would spend more money on the generator than you would save from buying electricity from the power company, most people would not spend the extra money on the generator. Especially if you would not get much electricity out of it.
simply because generating electricity using wind generator is not effective for small projects.also it needs an electricity regulator as this generator gives non constant electric force(called emf).do not forget it is also expensive and have to be applied just in areas exposed to wind motion all over the year.such places are rarely found
