How does wind energy work at your house? The question is a good one but a better phrasing of the question may be
, How can you make wind energy work?
These are the things that you need to know in order to evaluate how you can make wind energy a reality at your home...
Take some information about your specific microclimate - This is something you need to realize from the get-go. The roof that you might use for a wind energy generator is very much different than where you might install a wind turbine in your backyard for example. That is because the dynamics of the way the wind blows in each location are little bit different. You have to take the time and make the effort to get to know the microclimates around your house. The only way to do that is to take a little bit of data with a small cup-type wind turbine device called an anemometer. Once you collect that information for a few months you will have pretty good picture of how the wind blows at each exact location and you can compare those locations in terms of energy potential you might be able to get out of them.
Understand any laws that effect wind turbines near you - The permit that you will be required to get to install a wind turbine on your house in most cases will require you to get a particular type to be within compliance. You need to understand that before you get too far down the road because you would not want to buy a wind turbine that does not meet your permitting requirements. You will not be able to install a turbine that does not meet permitting requirements and you may have to move it to somewhere else in order to get along with your local government.
Decide what your goals for power creation are - It is a good idea to try to understand what it is you're trying to accomplish with the wind turbine before you begin as well. There are so many things that you can do. One very popular solution is to supply power for a battery bank. That battery bank consists of golf cart batteries. They do not have to be special batteries that are just for home wind turbines or renewable energy devices.
In summary, how does wind energy work is the best first question that anyone should ask who is thinking about renewable power at home.
