most of the renewable energy consumption on earth is from
World energy consumption 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.[55] 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.[56] In international public opinion surveys there is strong support for promoting renewable sources such as solar power and wind power.[57] 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.[58]
Energy in the United States The United States of America (USA) is the world's second largest producer and consumer of electricity.[42] It consumes about 20%[43] of the world's supply of electricity. This section provides a summary of the consumption and generation of the USA Electric industry, based upon data mined from US DOE Energy Information Administration/Electric Power Annual 2015 files.[44] Data was obtained from the most recent DOE Energy Information Agency (EIA) files. Consumption is detailed from the residential, commercial, industrial, and other user communities. Generation is detailed for the major fuel sources of coal, natural gas, nuclear, petroleum, hydro and the other renewables of wind, wood, other biomass, geothermal and solar. Changes to the electrical energy fuel mix and other trends are identified. Progress in wind and solar contributions to the energy mix are addressed. Expected changes in the generation environment during the next 5 years are discussed.
