Brazil wants to build enough wind turbines to power Sao Paulo within 7 years Link: Brazil’s economy is growing fast, and it is expected to need an increase of 50% in power generation capacity over the next decade. Currently, the country gets quite a lot of its electricity from hydro, but because it is becoming more reluctant to build new dams on its numerous rivers, it is now turning to another plentiful source of energy: Wind power. The country doesn’t have much of it right now, but a big wind turbine boom seems to be starting.
