The wind is a clean and plentiful source of energy. The Canadian Wind Energy Association (CanWEA) believes that wind energy could potentially supply up to 20% of Canada's electricity requirements.

Wind turbines used to generate electricity come in a wide variety of sizes. Large wind turbines, which are usually installed in clusters called windfarms, can generate large amounts of electricity. Large wind turbines may even produce hundreds of megawatts (MW) of electricity — enough to power hundreds of homes. Small wind turbines, (see Figure 1), which are generally defined as producing no more than 100 kW of electricity, are designed to be installed at homes, farms and small businesses either as a source of backup electricity, or to offset use of utility power and reduce electricity bills. Very small wind turbines (20 – 500 watt units) are used to charge batteries for sailboats and other recreational uses. FIGURE
