Cascade Engineering said, October 27, the Swift wind turbines for the houses and other buildings, is in the U.S. and Canada.

The quickly tried to turn away from small wind turbines performance with a design that reduces noise. Moreover, the turbine with a home, as a free zone or pole-Round.

Like other turbines, the Swift and the leaves that turn a generator of energy. But instead of the typical three layers, which Swift has five years and a ring of around them. That “foreign broadcasters’ circle of lowering the noise to 35 decibels and reduces vibration, according to the company.

The turbine, with a 7-foot in diameter, also have two ribs directly into the turbine, to oppose the wind. Can be rotated 360 degrees and at the verdict, when the wind is too high.

You can use 1.5 kilowatts, with 14 mph winds and about 2000 kilowatt-hours in the course of a year, the company says. U.S. households consume in general from 6500 to 10,000 kilowatt-hours per year, according to the U.S. Energy Information Administration.

At a price of $ 10,000 is installed, it is a little lower than the normal price per watt electricity from solar cells. But the state of the rebates, the cost of electricity, solar and wind power, or make a big difference in the actual cost in advance. Cascade believes that the return on the initial costs are as low as three years, but very differently.

The small wind turbines recently benefited from the expansion of renewable energy tax credits to consumers U.S. $ 1,000 of tax credits for residential and $ 4000 for commercial buildings.

Waterfall, with headquarters in Grand Rapids, Michigan, has 9 SWIFT turbines in the U.S. and has a backlog of 25 orders, according to Jessica LEHTI, the head of the Directorate marketing.
