UN panel foresees 80 per cent of world’s energy as renewable by 2050 - Macleans.ca
The United Nations Intergovernmental Panel on Climate Change says that renewable resources (like solar and wind power) could provide up to 80 per cent of the world’s energy needs by 2050, helping to reduce greenhouse gases. In order to get there, governments will need to spend a lot more money and shift their energy policies to integrate renewable sources into existing power grids, the panel says. Further development of renewable sources will demand investments of $1.5 trillion by 2020, and maybe up to $7.2 trillion from 2020 to 2030, they said. The use of renewables is rising just as their price keeps declining, so the right policies could expand them significantly.
