The wind is a resource readily available. A wind farm of 100 MW can supply energy for over 400 thousand people.

The intensity of winds in Brazilian Northeast makes that the efficiency of a wind plant is similar to that of a large hydroelectric plant.

The wind power can also supplement the hydroelectric power in periods of smaller rates of flow of basins because there is more wind in dry periods, while humid periods have less wind.

Considered as an expensive source in the past, now wind power can compete with other sources of energy, such as the thermal ones, the nuclear ones and those derived from other fuels (like natural gas, coal, combustible oil etc.), since the tariffs charged are below the ceiling of those technologies in Brazil. It still has the advantage of being implemented quickly, since the installation of machines takes 18 to 24 months, what is inferior to the time required by other energy sources.

Involving approximately US$ 2 billion worldwide, 30 thousand huge turbines in several countries generate around 70,000 MW. This amount can supply 10 per cent of the global needs of electricity until 2020, what means a reduction in the 10 billion tonnes of carbon dioxide emission in the atmosphere.
