Amazon Energy security is being threatened by climate change and hydroelectric power plant projects in the Amazon as well. We know that hydropower in the Amazon region is the dominant energy source, as it has the largest river basin in the world. But will just that be enough? The truth is, no. A recently conducted study on Global Environmental Change warns that if river discharge and reductions in rainfall continue in the next decade, the energy capacity of hydroelectric plants in the Amazon will decrease dramatically. The study evaluated 351 proposed hydroelectric projects in the Amazon basin. The findings reflect the following information: Hydroelectric power generation in many places will be reduced by mid-century due to hydrological changes. Hydropower production declines as river discharge becomes increasingly variable. Solar and wind energy are considered alternative energy sources and are becoming increasingly important.
Continental-scale evaluation to determine the viability of hydroelectric plants in the Amazon Stephen Hamilton is co-author of the study and is also an ecologist at the Cary Institute, in which he explains the following: «Hydropower projects in the Cell Phone Number List Amazon Basin are designed to operate under flow regimes based on historical river levels. Climate change is altering these patterns, meaning that many proposed projects are unlikely to be as effective under future conditions . The IPCC used several climate change scenarios and modeled them on a continental scale for both rainfall and river discharge to know where and how energy production could change. How were they estimated? 1.- Runoff and precipitation influence river discharge and continental-scale changes were estimated using general circulation models that use climate data to project future precipitation trends.
Tickets include information on: air temperature _ Humidity wind speed solar radiation atmospheric pressure The precipitation. 2.- Energy production at the proposed dam sites were estimated using information on the maximum and minimum river flows at each site under current and future climatic conditions. Comparisons were also made of the costs of this type of renewable energy with respect to solar and wind energy in the Amazon region. The 'levelised cost of energy' (LCOE): was used to determine how climate change would alter the cost of energy and the viability of the project, since it is necessary to know the unit price of the energy necessary for a project to production thereof achieves a balance. LCOE takes into account the costs of: Construction Operation Maintenance of the proposed power plants. The team made projections in climate change scenarios for hydroelectric plants in the Amazon The projections of the Hydroelectric Power Plants in the Amazon were made according to the current situation, intermediate and in the worst case, that is, all possible scenarios.
