Renewables now make up 26% of global electricity generation, second after coal

Renewable energy is derived from resources that are replenished on a human timescale; examples include sunlight, wind, rains, waves, tides, geothermal heat and biomass. Renewable energy is used in three main areas: electricity generation, air and water heating and cooling, and transportation. Renewables are also suited to provide off-grid energy solutions in rural and remote areas. The overall production and use of renewable energy usually produce minimal greenhouse gases and have the potential to significantly reduce air pollution compared to hydrocarbon alternatives. Deployment of renewable energy also has potential energy security benefits, with renewable resources spread over wide geographical areas.

In light of the current greenhouse gas-driven warming of the climate and the associated impacts, a global transition to low carbon energy is underway with renewable energy at the forefront. Related technologies are rapidly becoming more efficient and falling in costs; some renewable energy forms like solar PV and onshore wind that once depended heavily on government support are now at or approaching cost-parity with fossil fuel generation. Since most renewables produce electricity, increasing the share of renewable energy in the whole energy system can be achieved by electrifying the heat and transport sectors, in combination with increasing the proportion of electricity provided by renewables. Besides electrification, the transport sector can benefit from biofuels which can substitute for oil products. The heat sector can see further deployment of solar water heating, biomass-fuelled burners and direct geothermal heating. Renewable energy is expected to continue expanding its share in the energy mix, as costs come down, innovative technologies are commercialised, and environmental drivers strengthen. In the short term, the EU has a target for 20% of all electricity to be generated from renewables by 2020. However, to meet long-term climate and sustainability goals, renewable energy deployment must accelerate in all sectors, enabled by policy and markets.
