Energy mix
The energy mix is a group of different primary energy sources from which secondary energy for direct use - such as electricity - is produced.[2]
In 2007, the global primary energy use was 12.5 million tonnes (12,300,000 long tons; 13,800,000 short tons) oil equivalent, or 145,375 gigawatt-hours (523,350 TJ).
According to the International Energy Agency (IEA) 13,6% of world primary energy was used by the European Union (EU). Within the EU, 75.9% came from fossil fuels, 14.1% from nuclear power, 7% from biofuels, 2.9 from renewable energy resources.[3]
Overall primary energy consumption in the United States in 2015 relied most on petroleum (35 quadrillion British thermal units (3.7×1016 kJ)), natural gas (29×1015 BTU (3.1×1016 kJ)) and coal (16×1015 BTU (1.7×1016 kJ)). Renewables contributed 9×1015 BTU (9.5×1015 kJ) and nuclear power 8×1015 BTU (8.4×1015 kJ).[4] In the same year, about 4 million GWh of electricity were generated in the United States, 67% of which was generated from fossil fuels (coal, natural gas, and <1% petroleum), 20% from nuclear power, 6% hydropower and 7% other renewables.[5]
