They also have lower wind startup speeds than horizontal designs, they emit less noise, and they are generally smaller, making them ideal for locations where taller structures are prohibited. The turbine does not need to be pointed into the wind to be effective, which is advantageous in areas where wind direction is highly variable. Vertical-axis wind turbines have their main rotor shafts arranged vertically.They are typically large and difficult to install, however, and they must be placed some distance apart from one another to minimize fatigue loads due to wake turbulence. This design is efficient because the blades always move perpendicular to the wind, receiving power through their entire rotation. The blades are placed a considerable distance in front of the tower and are sometimes tilted slightly forward into the wind. Horizontal-axis wind turbines have their main rotor shafts and electrical generators located at the top of a tower, pointing into the wind.Wind power in China increased twenty-fold from 2005 to 2009. Denmark ranks ninth in the world in wind power capacity, but generates about 19% of its electricity from wind. As of 2009, the United States ranks first in the world in wind power capacity, followed by Germany, China and Spain. Microturbines, by contrast, rarely produce more energy than is required by a single home. At 600 feet tall, it is nearly twice the height of the Statue of Liberty and can power 5,000 homes. The largest commercial wind turbine is Germany’s REPower 5MW. Wind turbines designed for residential use - sometimes called microturbines - are typically much smaller in size (both in height and rotor diameter) than their commercial counterparts, as well as their power output. After this direct current is converted into alternating current, it can then either power a house or be sent into the electrical grid, depending on local net metering laws.

A magnetic rotor in the generator housing spins along a shaft within loops of copper wire bound around an iron core, which generates an electrical current. Turbine blades are shaped in such a way that wind causes them to rotate, which then makes a chain of shafts and gears turn. The basic method by which turbines produce electricity is quite simple, and inspectors may want to familiarize themselves with these increasingly popular constructions.

Wind turbines are structures that capture the wind’s kinetic energy and convert it into electricity.
