Have you thought about using wind energy to save money, or to be alittle more eco-friendly? Why not consider a small wind turbine for home use. Its not uncommon for someone in a good area to cut there electricity bill down to 8-15 dollars a month by using a wind turbine. The cost of a wind system is around 6000-20000 dollars depending on several factors. It is estimated to take about 6 to 15 years to recoup the cost. After that, your electricity is basically free. This is a good investment for people retiring who want a stable way to afford electricity.
