Renewable energy is energy that is derived from natural processes (e.g. sunlight and wind) that are replenished at a higher rate than they are consumed. Solar, wind, geothermal, hydropower, bioenergy and ocean power are sources of renewable energy. The role of renewables continues to increase in the electricity, heating and cooling and transport sectors.

Renewable energy, together with energy efficiency, is essential to delivering the low-carbon energy future that the international community agreed upon at the United Nations’ 21st Conference of the Parties (COP21) at the end of 2015. Renewable energy deployment is driven by supportive policies that aim not just at decarbonisation, but also – and sometimes even more importantly – at improving energy security and reducing harmful local air pollution.
