Traditional energy sources are on their way out. Fossil fuel costs are shooting up because we are running low on them, so we need to prepare for the future. We need to change the way we think about how we get our energy and how much we are using to change our lifestyles into sustainable lifestyles.

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.

Using the right set of plans even homeowners who don’t know anything about construction or electricity can build their own alternative energy sources right in their backyards, such as wind power generators.

Homemade wind turbines can currently generate enough power to reduce the average household’s monthly energy bill by as much as 70% per windmill. With inexpensive plans they can also be built for as little as $200 using some recycled parts.

They can also be built with materials from a local hardware store and basic tools. An easy way to estimate how much power your wind generator can create:

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.

An average home uses about 12-20 kWh/day. Of course if you conserve your power you can reduce that to much less – even down to 5 kWh per day. So if you don’t have a great average wind speed in your area, a wind power generator can significantly reduce your power bill, and it may only cost you $200.
