UN: Renewable energy key in climate change fight

ABU DHABI, United Arab Emirates — The top climate panel has concluded that renewable sources like solar and wind could represent up to 80 percent of the world's energy needs by 2050 and play a significant role in combating climate change.

But the U.N. Intergovernmental Panel on Climate Change warned that governments will have to do more to introduce policies that integrate renewables into existing power grids and promote their benefits in terms of helping reduce air pollution and improving public health.

Governments endorsed the renewable report Monday after a four-day meeting in which Saudi Arabia and Qatar fought unsuccessfully to water down language on the benefits of renewables. Brazil — a major ethanol producer — opposed language raising negative effects of biofuels.
