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]
Renewable energy in Australia Renewable energy in Australia deals with efforts that have been and continue to be made in Australia to quantify and expand the use of renewable energy in the generation of electricity, as fuel in transport and in thermal energy. Renewable energy is created through electricity generation using renewable sources, such as wind, hydro, landfill gas, geothermal, solar PV and solar thermal. Total renewable energy consumption in Australia in 2015 was 346 petajoules (9.6×1010 kWh) (PJ), 5.9% of Australia's total energy consumption;[1] compared to consumption of 265PJ in 2011/12, 4.3% of Australia's total energy consumption.[2] Of all renewable energy consumption in 2015 (in order of contribution) biomass (wood, woodwaste and bagasse) represented 53%, hydroelectricity 19.2%, wind 10.7%, solar PV 5.1%, biogas 4.7%, solar hot water 3.8% and biofuels 3.6%.[3] Bioenergy (the sum of all energy derived from plant matter) represented 61.3% (211.9PJ) of Australia's total renewable energy consumption in 2015.[3]
