Wind and sun 'will fuel future': UN report

Renewable sources such as solar and wind could supply up to 80% of the world’s energy by 2050 and play a significant role in fighting global warming, a top climate group claims.

But the UN Intergovernmental Panel on Climate Change said that to achieve that level, governments would have to do more to introduce policies that integrate renewables into existing power grids and promote their benefits in terms of reducing air pollution and improving public health.
