One of the most important is that wind power is the least expensive of all other forms of alternative energy. Wind turbines generate electricity at around 5 cents per kWh (Kilowatt Hour), which is comparable to the new coal and/or oil burning power plants. The costs are projected to decline even more as technology improves, and this is very important because most of the cost with wind power is in manufacturing. Once the wind turbines are in place there is little cost to maintain and wind power is free.
