Almost 140 countries will be powered solely by renewable sources by 2050.
Wind power, water and solar production at a higher efficiency than fossil fuels, will bring a reduction in energy consumption say Stanford University research.
A feat that will also bring a net increase of around 24 million jobs and significantly reduce air pollution related deaths by up to 7 million per year.
As a result of the increase, energy prices are predicted to stabilise and along with health and climate related costs, savings of upwards of 15.6 trillion are expected.
For the scheme to be viable, 1% of total available land and rooftop area would be required. Much of the land between wind turbines is open space that can be utilised for other means. The US, Europe and China are expected to convert more easily, due to the abundance of unused land available.
Research Scientist from the University of California, Mark Delucchi, states: “It appears we can achieve the enormous social benefits of a zero-emission energy system at essentially no extra cost.”
“Our findings suggest that the benefits are so great that we should accelerate the transition to wind, water and solar as fast as possible, by retiring fossil fuel systems early wherever we can.”
Factoring in costs of energy, health and climate, the new system is expected to total around 25% of current fossil fuel based systems.
