Wind energy is readily available but wind power is not. Unfortunately, the wind power system has not reached the status of becoming a regular power system. However, the good news is that the concept is picking up.
Alternative electric energy has seen a marked increase in investment over recent years. As the world responds to the range of crises presented by global warming, viable solutions are being sought to combat the problem.
With environmental concerns as they are today, renewable energy is enjoying a time of heightened interest. Renewable energy can come from a number of sources such as wind, water, sunlight and heat from geothermal sources. Today, approximately 20% of the energy in the world comes from renewable sources. While most of this comes from burning wood a very large amount also comes from hydroelectricity.
