Reducing greenhouse gas emissions of Amazon hydropower with strategic dam planning.

ABSTRACT: Hundreds of dams have been proposed throughout the Amazon basin, one of the world's largest untapped hydropower frontiers. While hydropower is a potentially clean source of renewable energy, some projects produce high greenhouse gas (GHG) emissions per unit electricity generated (carbon intensity). Here we show how carbon intensities of proposed Amazon upland dams (median = 39 kg CO₂eq MWh^-1, 100-year horizon) are often comparable with solar and wind energy, whereas some lowland dams (median = 133 kg CO₂eq MWh^-1) may exceed carbon intensities of fossil-fuel power plants. Based on 158 existing and 351 proposed dams, we present a multi-objective optimization framework showing that low-carbon expansion of Amazon hydropower relies on strategic planni
