Renewable Energy – Lesson 3 – Wind Power

Today, much emphasis is being placed on renewable energy, living green, and the environment, Never before has there been such a strong and growing grass roots movement toward renewable and sustainable energy and environmental responsibility. In truth, this movement is to a significant extent motivated by financial concerns of people who are desperate to cut utility bills by finding ways to conserve energy. However, the end result is the same; much more interest in and progress toward bringing renewable and sustainable energy technology such as wind power into the mainstream.

Wind power is a concept that, like solar power, has been around for a long time and sparsely used. In the last five years, this has changed dramatically. In the Midwest, one can see many examples of eclectic cooperatives purchasing land or at least leasing rights to construct huge farms of wind generators to augment their electricity generating capabilities and to bring down the cost of electricity to their customers. While this is a great development from an environmental aspect, the average customer sometimes does not see a great reduction in their monthly electric bill.

Wind power for the average private residence is possible. While technically possible to go off the grid with wind power, this is not as reliable or advisable compared to solar power. However, residential wind power generators do make sense in that they can significantly reduce one’s electric bill. Unlike the massive towers with gigantic propellers, that one sees the electric cooperatives using, residential wind generators are compact, relatively small and usually unobtrusive.

These residential wind generators can be free standing with their own tower, usually 20 to 30 feet tall, or they can be mounted on a tower which is in turn mounted on the roof of the house. The residential wind generator does face some challenges that solar power does not. The configuration of a wind generator generally requires that the propeller be at least 20 or 30 feet off the ground, especially in a dense residential area. Depending on the neighborhood, some will run into zoning restrictions that might prevent them from having a tall tower on or around their house. However this is the exception rather than the rule. Most homeowners will be able to install their wind generator with a minimum of trouble and expense.

Most wind generators are relatively affordable and can be paid for in the first two years with the savings in the monthly electric bill that they make possible. People are usually surprised by how little wind is necessary to generate a significant amount of wind power. This will vary according to region, but most places will have sufficient wind to generate at least some wind power every day.
