<P> Based on REN21 's 2014 report , renewables contributed 19 percent to our energy consumption and 22 percent to our electricity generation 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 % 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 United States heavily investing in wind , hydro , solar and biofuels . Renewable energy resources exist over wide geographical areas , in contrast to other energy sources , which are concentrated in a limited number of countries . Rapid deployment of renewable energy and energy efficiency is resulting in significant energy security , climate change mitigation , and economic benefits . In international public opinion surveys there is strong support for promoting renewable sources such as solar power and wind power . At the national level , at least 30 nations around the world already have renewable energy contributing more than 20 percent of energy supply . National renewable energy markets are projected to continue to grow strongly in the coming decade and beyond . </P>
