Wind Power Systems

Adaptable, historic and the fastest-growing form of energy generation in the world, non-polluting wind power provides cost-competitive energy for uses as diverse as personal property energy generation, agricultural irrigation, municipal water plants and commercial facilities. Generally, turbines come with a five-year warranty.

Though wind power systems are often cheaper than solar initially, the long life and near-zero maintenance of solar arrays make them cost-competitive with wind power over the long haul. A close examination of the qualities of a given site allows us to recommend which of these technologies is best for you. For wind power, these qualities include:

• Frequent breezy conditions
• A likely and suitable location within 300 – 500 feet of the home
• Absence of trees within a few hundred feet of that location
• Location on the property
• Agreeable neighbors

Wind turbines convert kinetic energy into electricity by spinning a generator. Recent improvements in blade designs have improved energy capture and reduced noise, while still utilizing the same principles at work in older wind generators: the spinning hub transmits energy generated by blade rotation along wires to a battery bank or utility grid interconnection point. The towers can be tubular or lattice, but either design allows for periodic maintenance. Well-situated towers that take best advantage of breezy conditions are capable of producing clean and sustainable electricity in sufficient volume to supply grid power.

Noise and bird deaths were initial negative considerations, but improvement in wind technology and equipment and studies of bird migration paths have greatly reduced those effects. In fact, correctly sited wind generators produce no more noise than a home refrigerator. And far more birds die from collisions with windows than will ever die from wind generation equipment. Current estimates report that of every 10,000 human-related bird deaths, wind turbines cause so few deaths as to be reported as “less than one.” There is much information available via the Internet that can educate the consumer about this environmental issue, but correctly sited systems and many design improvements over the past years have reduced bird deaths to negligible levels.
