Wind Turbine Classifications: 1) Residential or small wind - Less than 100 kilowatt output: Used on a home, farm or business. 2) Community or middle wind - Range between 100 kilowatt and 1 megawatt output: Used to feed a specific load with the excess going into the local electrical ...
And the bigger a turbine is, the harder it is to maintain. Wind turbines occasionally need big parts, like blades or generators, replaced. That is challenging on terra firma. But on land, a crane can brace itself against the earth. At sea, “jack-up” vessels achieve similar ...
