Are wind-driven turbines from houses ineffective?
There are a number of reasons that having wind turbines on the tops of individual homes would not be very practical, at least in the United States.
- They are too expensive relative to the amount of power that they can generate. So individuals would not be inclined to buy them for their own use. Companies are also not likely to want this because costs are too high.
- The power system in the US is not set up right now to be able to monitor how much power comes in to the grid from each house and pay for that.
Recently, a group of Dutch researchers published results of a study for one year, on the wind installations, of small and medium capacity. As the study has shown, wind installations, in small and medium capacity, seem ineffective.
Moreover, most wind installations studied, have produced only a few hundred kWh per year. One of the cheaper, Energy Ball (which costs 5,000 euros), generated, on average, only 73kwh per year, which only covers the use of one incandescent light bulb, used in the living room ... Taking account of other costs (maintenance, etc..) researchers have concluded that these low-capacity wind installations are ineffective.
Certainly, however, no matter these results, the society must move to other non-conventional energy resources. In economic terms, they will be considered effective by the producers by then.
