Introduction to wind energy systems

Abstract

The main ideas of wind energy are explained in this piece, along 
with the science and mechanics of how they work. It talks about how wind 
energy is turned into the spinning of a rotor and the important factors that 
determine how well this change works. Then it gives an outline of the different 
bits and pieces that make up windmills. Other things that will be thought about 
are how to connect to the power source, how common it is to use wind energy to 
make electricity around the world, how much it costs, and what research and 
development needs to be done.
