Energy production and drinking water demand could combine for water shortage by 2040

Researchers from Denmark and the U.S. have issued reports that spell trouble for the world’s future water needs, according to a release from Aarhus University.

Drawing from three years of research, the reports state that competition between drinking water and energy demand will result in water scarcity for 30-40 percent of the world by 2020. If energy and water usage trends continue as projected, by 2040 the entire world will lack the water to simultaneously quench its thirst and meet energy demands.

Electricity is the primary source of water consumption in most countries, because all power plants excepting wind and solar systems require water cooling cycles.
