A small wind energy system works on a lower scale than industrial sized wind farms. Industrial wind farms produce hundreds of megawatts of power, enough to power cities. However, they also cost millions, if not billions to construct. The average homeowner isn’t sitting on a few hundred million to invest in alternative energy.
In fact, the goals of the average homeowner are ideally met by small wind energy systems. They are meant to produce enough energy to take a chunk out of, or completely offset the power needs of a single household. They usually have a capacity of less than five kilowatts, which is fairly small in comparison.
There are individual turbines running now with a capacity of 6 megawatts. To put it into perspective, that’s more than 100x the capacity of a 5 kilowatt system; which is the high end for small wind energy systems. Most will actually fall under the 1 kilowatt mark. And realistically, for the environments these systems occupy, that’s an ideal format. Many will find their way onto condominium complex roofs, or the roof of a house. There’s no building code that requires the roof of a structure to be able to hold up tons of weight, and that’s exactly what you get when you start building large scale wind turbines. So the small ones work better for the niche they’ve evolved to fill.
