How Will Hydroelectric Power Generation Develop under Climate Change Scenarios? [PDF]

, 2011
Climate change has a large impact on water resources and thus on hydropower. Hydroelectric power generation is closely linked to the regional hydrological situation of a watershed and reacts sensitively to changes in water quantity and seasonality.

Siphon-type hydroelectric plants: application for power generation in a low head dam in southern Brazil

The Journal of Engineering and Exact Sciences
Hydroelectric energy continues to be the most representative renewable resource in the world, accounting today for 40% of installed capacity. The availability of water, combined with the technologies for generating electricity at a reasonable cost, have sustained the success of this type of generation over the years.

Patterns of understorey bird diversity across Amazonian forests: survey effort and range maps predict local species richness

Ecography, EarlyView.
Species diversity typically increases from higher to lower latitudes, but the regional‐scale variation along this geographic gradient remains unclear. It has been suggested that species diversity throughout Amazonia generally increases westward toward the Andes, but this pattern and its environmental determinants require further investigation for most ...
