The Basics of Wind Energy

For several hundred years people have used wind for an energy source. From the windmills that can still be seen in Holland to the American farmlands, the wind has been utilized to help grind the grain or to pump water. Wind energy is not a new idea! It is just getting more attention today due to our energy crisis. Today there are wind turbines to change the wind's energy into useable electricity.

Similar to windmills the wind turbines get attached to a tower, so it can capture the right amount of the wind's energy. A good elevation for these turbines to be the most effective is about 100 feet or higher. This way they can draw energy from the fastest winds that are not as turbulent as they are on the surface.

Turbines with their blades that are similar to propellers catch the energy from the wind. There are normally about 2 to 3 blades attached to a shaft which in turns forms what is a called a rotor. The blades turning in the wind create lift and drag. Drag happens when the wind hits the front of the blade. Lift happens as a wind pocket occurs on the backside of the blade. By combing the two forces it makes the rotor turn similar to an airplane propeller. And the shaft is turning a generator and this is what creates electricity.

A wind turbine can be used by itself on a small scale. This type of wind turbine are usually used either for communication functions or for pumping water. But farmers, ranchers, and homeowners the reside in areas that have plenty of wind, can utilize the turbines for electricity there by lowering their power bills.

But for a larger application the turbine can be used in groups or combined with solar power applications. These larger projects can be part of an utility grid power system. In this size of operation your would have to have many turbines working together in a wind plant of sorts. Many of the providers of electricity today do just that to supply the needs of their particular customers. Some of the power companies are now buying excess energy from their customers who have wind energy.

With all the fossil fuels being depleted today, all of us need to look for alternative power sources to use. Wind energy and solar energy are the top two alternatives today. These can even work together to provide power for businesses and homes.

Wind energy is 100% renewable an causes no harm to the environment. This is the type of energy that you need to be using these days worldwide. You could ultimately save 100% on your energy costs, through using this power along with other forms of renewable energies. You will also being doing something good for your environment.

So look into getting a wind energy system setup for you home or business today. You will not be sorry that you did and for more information on this topic, there is plenty of information available through the Internet, local home building supply stores, and your local power company.


How To Build A Wind Generator










Earth4Energy


When I bought this product I was just looking for some good do-it-yourself plans for a quality wind generator, but what I also received along with this,where plans to build a solar panel, and a membership into a club that just keeps giving. What I meen is, as earth4energy adds more information, more content, more videos and new ways to save money and the enviornment, I get all this information, for life, at no extra cost, and so will you.

And you know it wasn't long before people noticed the wind generator above my roof, that they started asking questions. Some I directed to Earth4energy and some wanted to pay me for a wind generator and the istallation so it looks like I've got a little buisness going on the side.

With the package you'll receive ansers to any questions you may have just by asking. I had a question on connecting my system into the grid and found all the information I needed for a grid-tie system.

So to keep it short I just want to say i'm pretty eccited about Earth4energy and I have to think anyone else interested in renewable energy sourses, green energy and doing their part for the enviornment would also want to get involved with this club.
