traditional biomass
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.
world energy consumption
according to nreap criteria around a third of energy consumption (32.5%) is used in the heating and cooling sector. the heating and cooling sector (also known as the thermal sector) includes domestic heating and air conditioning, industrial processes such as furnaces and any use of heat generally. the electricity sector and transport sector are also projected to account for around a third of energy consumption each at 33.6% and 33.9% respectively. the proportion of energy use in each sector is similar to that of 2016. in order to meet spain’s overall target for 20% use of renewable energy (it was just 8.3% in 2005) in gross final energy consumption (20,505 ktoe) by 2020 targets have been set for each sector as follows: 17.3% renewable energy use in the heating and cooling sector, 39% in the electricity sector and 11.3% in the transport sector. total annual energy consumption is projected to be 98,693 ktoe (98.7 million tonnes of oil equivalent) by 2020. the report expected spain to produce a surplus of 0.8% above the 20% target (20.8% total) for renewable energy use which would be available for other countries to meet their renewable energy targets under the "cooperation mechanism".
