Modern wind turbines are manufactured with three-bladed rotors with diameters of 70 to 80 meters mounted on top of towers with 60 to 80 meter heights. A typical turbine in the United States in 2008 produces more than MW of electrical power. The power output of the turbine is controlled by rotating the rotor blades to change the angle of the wind hitting the blade. This is referred to as “controlling the blade pitch.” The turbine is pointed into the wind by rotating the nacelle about the tower, which is called “yaw control.” (Bosik 2008, 50)
This paper presents a comprehensive evaluation of the energy production, economic, social, and political impacts of Ontario's microFIT Program - a feed-in tariff for micro-scale renewable energy projects. In an effort to determine whether the program can be justified from political and sustainability perspectives, the paper examines the government’s goals for the program and determines whether they have been met; investigates the full range of program benefits and detriments, and utilizes sustainability assessment criteria to evaluate whether the program can be considered sustainable; and assesses whether policy acceptance has been achieved among various stakeholder groups.
