Small Wind Generators
Have you ever wondered if you could save money on electricity by installing a small wind generator at your home? Learn what wind energy is, how it works, and what it can do for you. In addition, Dr. Vogl will discuss components of wind generators, tower height, how to choose a site for the tower, as well as current legislation and zoning of wind towers. Bring one of your electric bills, a notepad, and a calculator to determine the savings on a typical month’s performance of a wind tower versus your current source of electricity. Drs. Robert and Sonia Vogl, both retired professors from Northern
Illinois University,have presented programs on alternative energy and solar electricity in over a dozen countries.They have installed a 3.2 kilowatt grid-connected photovoltaic system and a one kilowatt wind generator which provides 70% of their home electrical power. They are active in preserving natural areas and have dedicated 60 acres of their 180 acre home farm to prairie and woodland restoration projects. Robert and Sonia are founders and officers of the Illinois Renewable Energy Association.
