The amount of power you can make will depend on the diameter of your windmill generator blade and the average annual wind gust you receive in your area. The formula for computing your annual output is KWH/year = 0.01328 (D^2) (V^3) in which D squared stands for the blade's diameter and V cubed stands for the average wind velocity. Use this formula to calculate how much electricity and thus savings on electric bill you can make with your windmill generator.

A well designed wind turbine can generate sufficient amount of electricity even if you don't live in a windy area. To maximize the potential of your wind turbine generator, use a high standard battery to store the electricity generated while you're not using it. Take advantage of the time when you're not using the electricity generated by your windmill generator by storing it to batteries ready for use when you come home at night.

You are doing something good for the planet if you use Green Energy from wind turbines because they do not give off greenhouse gases to work. You can save as much as 60 to 80 percent in your electric bill, and you're also giving your share to save the planet while saving some dollars to your bank account. In fact, some states give tax benefits to residents who install any form of sustainable electricity-generating device such as a windmill turbine.

Installing another form of sustainable energy generation device for home use like solar panels can even completely substitute your electricity from the grid with some excess. You can throw the excess electricity on the grid and your local power utility is mandated by law to compensate you. Not only will you eliminate your electric bill, you can even earn some few bucks with the excess electricity you're throwing back to the grid.

Investing on sustainable energy such as a windmill generator is really advantageous in the long-run both for you and the planet. The best part is the cost of installing sustainable power generation technology in your residence is decreasing with the advancement in technology and the huge chunk of the stimulus package going to sustainable power generation.
