Renewable energy is generally defined as energy that is collected from resources which are naturally replenished on a human timescale, such as sunlight , wind , rain , tides , waves , and geothermal heat . Renewable energy often provides energy in four important areas: electricity generation , air and water heating/cooling, transportation , and rural (off-grid) energy services.
Based on REN21 's 2014 report, renewables contributed 19 percent to humans' global energy consumption and 22 percent to their generation of electricity in 2012 and 2013, respectively. This energy consumption is divided as 9% coming from traditional biomass, 4.2% as heat energy (non-biomass), 3.8% hydro electricity and 2% is electricity from wind, solar, geothermal, and biomass. Worldwide investments in renewable technologies amounted to more than US$214 billion in 2013, with countries like China and the Uni
The incentive to use 100% renewable energy for electricity, heating and cooling and transport is motivated by global warming , pollution and other ecological as well as economic and energy security concerns. Shifting the total global primary energy supply to renewable sources requires a transition of the energy system . In 2013 the Intergovernmental Panel on Climate Change has said that there are few fundamental technological limits to integrating a portfolio of renewable energy technologies to meet most of
