Building Wind Power Generators For Your Home

October 12th, 2009 No comments

In the future, all of our energy will come from renewable sources. With traditional gas and energy costs skyrocketing, it is apparent that we need to find new ways to make energy production which are sustainable. We need to change our thought process about how we use the Earth and begin to convert our old energy grid into something sustainable.

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.[youtube:UQWf_-OEHOw;[link:DIY wind power generators];http://www.youtube.com/watch?v=UQWf_-OEHOw&feature=related]

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.

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.

Build Your Own Wind Power Generators

October 7th, 2009 1 comment

With rising fuel and energy costs, many people are looking for their own alternative energy sources. Wind power generators have been use on farms for many years in varying degrees, before electric power became so readily available.

Building your own wind generator into your home is easy. The rule of thumb is to find a place that is about 200-300ft from another obstacle or at least 20 ft higher. In North America the average wind speed is around 9m/s, which can give you a lot of power.

Wind power is a great source of renewable energy. It is much cheaper than solar power per Watt, as a wind turbine can generate 1000W while a single solar panel generates around 100 in daylight.

To turn the rotational energy of the turbine into electricity, the actual power generator is the DC motor. You will have to pick one up or order one – they can cost $50 on up depending on size.

You will also need to buy a tower, or improvise one. Recycling towers is a good idea – people that have old TV towers they don’t use any more may actually pay you to take them away. You will also need some great engineering blueprints to get you started on your project.

Many people have bought guides and made their own 500 watt turbines from scratch using PVC piping, a DC motor, TV tower recycled and a grid connector unit. This can be done in less than a week and for less than $300. On the other hand the same turbine might cost $1500 or $2500 commercially.

The basics of wind power generators have been around ever since the old windmills you still see at farms across the plains and prairies. Now you can find plans on the Internet for building your own system, or buy components or kits that contain what you need to know.

If you have a bit of land or a rooftop to place it on, some PVC, a DC motor and something to make a tower out of, you can put together a wind power generator with basic tools quite easily.
