Wind power is one of the cleanest sources to get electricity. To get large scale energy from wind, wind farms are used. What can we tell about wind turbine efficiency today?

To find out how efficient wind turbines or actually wind farms are, you need to know how they work. The wind turbines accumulate the power of the wind in two steps: the propeller blades are rotated by the wind, and the propeller then drives a shaft. Read the rest of this entry

What are proven wind turbines? As the history of wind power goes all the way back to 200 B.C and the they were simple wind mills built upon the horizontal axis principle I would say that they are proven.

The horizontal axis wind turbines are still the most common type of wind power generator. Read the rest of this entry

Ok, you have thoughts about how to build a homemade wind turbine. With the right instructions it’s not a very complicated work.

This is a small list of “think-about” things when you are starting your first wind energy project. It’s a random list and more of an idea list than a step by step that you find in your instructions material. Read the rest of this entry

What would you say if your neighbor mentioned she was going to build a mini wind turbine? Surprised? To be honest, it is not hard to build such wind generators and homeowners over the country are going for the challenge to make their own electricity. Naturally this is one way to utilize renewable energy.  Read the rest of this entry

When we are talking about how to build wind turbine blades, this picture might not be relevant. We have to start with something a bit smaller. Read the rest of this entry
