The International Energy Agency says the world will likely need to have around 48 per cent of total electricity generation sourced from renewable energy sources by 2035, if it is to meet the stated climate change goals of international governments.

In its World Energy Outlook 2013 report, a 760-page omnibus that is released each year by the conservative, Paris-based organisation, the IEA says that the use of renewables will need to double from the “current policies” scenario if it is to cap emissions at 450 parts per million.

As the table below shows, most of this increase comes from wind and solar, which will increase its share of total generation to 18 per cent. Critically, though, this means that the combined capacity of 2,700GW will be around 50 per cent of peak demand in 2035, and in some regions such as Europe it could be 90 per cent, and even in China and Japan wind and solar could account for more than 60 per cent of peak capacity.
