Renewables are the key to achieving a global temperature rise below 2oC, the widely-accepted limit to avoid irreversible climate-related damage, as per a report published by the International Renewable Energy Agency (IRENA).
The report also emphasised the positive benefits of a shift to renewable power. The deployment of renewable energy technologies creates jobs and stimulates economic growth, whilst preserving cleaner and healthier environments.
The report found that at least 85% of global power would need to be sourced from renewable energy by 2050 to meet out 2oC goals.
If those goals are met, an estimated 40 million people would be directly employed in the renewable energy and energy efficiency sectors. Additionally, the cost savings resulting from improved health, lower air pollution and avoided damage would equal a fivefold return of the additional investment needed to make this transition to a global low-carbon economy.
