Northeast wind farm turbines against scrubland vegetation

Wind farms in Northeast Brazil generate clean energy amidst the Caatinga vegetation, a unique Brazilian biome.

About this subject

Northeast Brazil concentrates the largest share of the country's wind energy, with farms installed in Caatinga areas, a biome exclusive to Brazil that covers about 10% of the national territory. The Caatinga is a steppic savanna adapted to long dry periods, featuring xerophilous vegetation such as cacti, bromeliads, and thorny shrubs. The installation of wind turbines in this region harnesses constant winds, especially along the coast of Rio Grande do Norte, Ceará, Piauí, and Bahia. Brazil is the third-largest wind energy producer globally, after China and the United States, with installed capacity in the Northeast exceeding 20 GW. The turbines, reaching up to 80 meters in height, coexist with local fauna like the three-banded armadillo and the Spix's macaw, endangered species. Wind power accounts for about 12% of Brazil's electricity mix, aiding decarbonization and economic development in semi-arid municipalities.

Frequently Asked Questions

Why is the Northeast ideal for wind energy?

The Northeast has constant and strong winds, especially along the coast, with average speeds above 7 m/s. The flat topography and low population density also facilitate the installation of wind farms.

Does wind energy affect the Caatinga?

Turbine installation can cause local impacts, such as vegetation suppression and collision risk for birds. However, environmental impact studies are mandatory, and many companies offset through reforestation and preservation areas.

What is Brazil's installed wind energy capacity?

Brazil has over 25 GW of installed wind capacity, with the Northeast accounting for about 80% of that total. The country is the third-largest producer worldwide, after China and the USA.
