Sustainable and renewable sources like solar and wind could supply up to 80 percent of the planet’s energy requirements by 2050 as well as play a role in fighting global warming.
But the U.N. Intergovernmental Panel on Climate Change say that in order to achieve that level, governments would have to spend much more money and introduce policies that integrate renewables into existing power grids, promoting their benefits in terms of improving public health and reducing air pollution.
After a recent four-day meeting, governments endorsed the renewable report Monday. The report reviewed solar energy, bio-energy, hydropower, geothermal, ocean energy and wind. However, they did not consider nuclear, the recent nuclear accident in Japan was not mentioned nor did it have any impact on the report’s conclusions.
The Intergovernmental Panel on Climate Change has said swift, deep reductions in use of non-renewables and non-sustainables are needed to keep temperatures from rising more than 3.8 degrees Fahrenheit (2 Celsius) above preindustrial levels, which could trigger climate catastrophes.
