How to Build A Wind Generator At Home

Fossil fuels and non-renewable energy sources cannot last forever. We are simply running out of them, and prices are skyrocketing. We need to change the way we use energy and the way we generate energy in order to make sure our lifestyle remains sustainable over the long-term.

Many people have already begun to think this way. Problems that we have previously had with renewable energy have been solved and new engineering breakthroughs have allowed us to take the next steps toward a completely sustainable future.

With good blueprints, even homeowners inexperienced in engineering or construction can create their own renewable energy sources, such as wind power generators.

Wind turbines can be made to reduce the average home's electricity bill by as much as 70%. They can be built, using economical plans, for as little as $200 using pre-used parts. The most expensive part might be a DC motor which can cost as little as $30.

They can be built with basic tools and parts from a local hardware store. You can estimate the amount of power a generator creates using the following formula:

Power(Watts) = (Wind Speed)^3 * (Blade Diameter)^2 * 0.00478

The speed of the wind is cubed, so it makes the most difference in your power output. For example, if you have a good average wind speed of 10mph and an 8 foot blade diameter, then:

W = (10*10*10) * (8*8) * 0.00478 = 305 watts/hour - x 24 hours and you can calculate 7.3 kWh generated per day by a wind power generator.

If you have an average home, you probably use about 12-20 kWh of power every day. Even if you don't have great wind speed in your area, an initial investment of about $200 to build a wind turbine is small compared to the savings you will get in free electricity for your house. Wind power generators are very good investments, indeed.
