Wind Turbines for Domestic Energy Use
As the popularity of alternative energy has grown, many brands of wind turbines, kits, and plans have popped up on the market for home use. While wind energy is definitely a smart move, it is also a big initial investment – a large home turbine can cost thousands of pounds. Therefore, it is important to do your research before you buy. This includes determining how much power you need to generate and where best to place your turbine in order to gain maximum efficiency.
Varieties of Turbines
Most turbines that are intended for home use are of the traditional windmill variety. These have a tall, narrow base with blades that rotate at the top. Vertical wind turbines are starting to become more common for at home use. Vertical turbines have two tall blades (or more) that rotate around the tower. The blades can be straight or curved. You can purchase a small turbine which can be mounted to a rooftop, but usually they need to be affixed to the ground.
Wind Turbine Height
The height of a wind turbine determines how much electricity it can generate; the higher the turbine, the more power it produces. In order for a residential turbine to be cost-effective, it should reach a wind speed of 10 miles per hour when placed at 33 feet from the ground. Turbines should always be placed at least 30 feet higher than any possible obstructions (buildings, etc.) within a radius of 300 feet.
Home wind turbines usually produce a capacity of 400 watts to 100 kilowatts. If a turbine is placed in a rural area with few obstructions and high wind speeds, it can generate as much as 10 kilowatts or .01 megawatts. However, the production of a turbine per hour is very dependent on the environment it is placed in, which is why professional advice should be sought.
When you install a domestic wind turbine, you probably aren’t expecting a huge generation capacity to power your home. You don’t have to go to such great lengths to obtain a huge amount of power from your turbine. However, your installer should still check the wind maps and wind data for your area in order to determine the ideal placement for your turbine. Hills, buildings, and other obstacles can have a significant impact on your turbine’s ability to generate power.
Regulations on Wind Turbines
Be sure to check with your local governing bodies before installing a wind turbine on your property. Many councils have regulations governing wind turbines that can affect your plans. There may be regulations regarding the height of your wind turbine or noise regulations that can impact you, so check out the rules before you select and purchase a wind turbine for your home use.
