Environmentalists in Brazil are protesting against the awarding of a tender for a controversial hydroelectric project…The tender was awarded to Norte Energia, a consortium led by a subsidiary of Electrobras, the state electricity company, after a series of court injunctions that had blocked and unblocked the auction process…Indigenous groups and environmental activists have staged several demonstrations in recent weeks, saying the dam is ecologically irresponsible. They also say it will threaten the livelihood of 12,000 families, most of them Brazilian Indians living on the banks of the Xingu river that would feed the facility…A Greenpeace spokesman said the government should have used other possible energy sources such as wind power, biomass or solar.
