Drought Might Curb Global Power Output

Paris (AFP) - Thousands of power plants worldwide face sharp reductions in electricity output by mid-century due to more frequent heatwaves and drought driven by global warming, according to a study published Monday.

"We need to be concerned as electricity will become more expensive and less reliable in the future due to climate change," co-author Keywan Riahi of the International Institute for Applied Systems Analysis in Austria told AFP.

If warming continues unchecked, higher temperatures and water shortages could, by 2050, cut capacity in hydro-electric plants by nearly four percent, and in thermoelectric plants -- powered by fossil fuels, nuclear power or biomass -- by 12 percent.
