Of course if the propeller freezes in place, the turbine won't be of much use. Benefits of Wind Energy back to top Like solar power, a wind energy system is an entirely clean source of power. The only potentially hazardous materials involved are the storage batteries. Wind turbines produce no emissions, use no traditional fuel, and can provide reliable year-round power given the right location. Wind generators require relatively little maintenance, but it is recommended that the generator receives annual visual check-ups to ensure the propeller blades haven't been damaged.
Wind turbines are very useful in almost any marine or household electrical system.
In marine use, the movement of the boat will raise enough breeze to get the generator turning even when actual winds are fairly low, making them an extremely reliable source of on-board power. They can also be configured to power dedicated water pumping systems, which may be of particular interest to individuals currently without running water. For commercial and industrial use, wind turbines are particularly useful in rugged remote locations such as mountaintop repeater stations or offshore oil platforms. High elevation and offshore or seaside remote sites often have fairly high year-round wind current that will make the most of wind generation systems. Industrial grade wind generators are available to withstand the worst storm winds present at such sites.
