Half of the entire world's electricity must come from renewable sources by 2050, to avoid irreversible impacts of climate change, the International Energy Agency (IEA) has claimed.
In order to cut global carbon emissions by 50 per cent by 2050, it is essential to halve the electricity generation that is not renewable, according to the organisation.
To achieve this, governments must do more, claimed IEA executive director Nobuo Tanaka.
He said: "Setting a carbon price is not enough. To foster a smooth and efficient transition of renewables towards mass market integration, renewable energy policies should be designed around a set of fundamental principles, inserted into predictable, transparent and stable policy frameworks and implemented in an integrated approach."
Among the recommendations for governments was removing non-economic barriers such as administrative hurdles, obstacles to grid access and social acceptance issues.
E.ON has been increasing the amount of renewable electricity it generates and recently opened the output of the first two phases of a wind farm that will be the world's biggest.
The wind farm in Roscoe, Texas became operational last month, with the capacity to generate 335.5 megawatts (MW) of electricity – enough to power over 100,000 homes.
When all phases are completed, the wind farm will have 627 wind turbines and a total capacity of 781.5MW.
