Extracting power from the Amazon basin

Brazil´s plans for scores of hydropower dams on rivers deep into the rain forest are discussed. Two dams have been built by 1988. Tucurui, already completed, generates 4000 megawatts (MW) of electricity from a 2430-square-kilometer forebay; when complete, its power plant will have a capacity of 7300 MW. Balbina which has been a problem to develop, is due to start operating this year, six years behind schedule; it will create a largely stagnant lake the size of Tucurui´s, but will have a capacity of only 250 MW. Economic, social, and environmental issues that surround further projects are examined. Brazil´s hopes of easing economic strain by installing more efficient equipment, implementing better industrial processes, and promoting conservation are discussed.<>
