The most efficient wind generators have a blade diameter of roughly 8 feet and a total of 3 blades. If you find that 8 feet is simply too large for your backyard then you can cut it back as needed. Just make sure the shape is the same.
Remember, our goal is to produce 1000 watts of power and to achieve this output you will need to use blades of about 8 feet in diameter with wind speeds of at least 20 miles per hour.
The best materials to use to create your blades is ABS or PVC pipe. Pipe that is between 8 and 12" in diameter works the best.
Note: When using pipe, keep in mind these where intended to be used underground. We recommend painting them with a UV inhibitor in order to prolong the life of your wind generator

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
