Total final consumption, also known as final energy, accounts for the consumption of each fuel in its final form of energy. In 2018, 21% of energy was consumed as electricity and 64% directly as fossil fuels (e.g. combustion of oil). In 2019 63% of electricity was generated by fossil fuels.
Carbon intensity of TES is the annual mass of emitted CO₂ per unit of total energy supply, and is a measure of the carbonisation of an energy system.
There was no net-decarbonisation of the world energy system from year 2000 to the end of 2016.
In 2019 the world continued to add supplies of fossil fuels. Carbon-free additions were greater than fossil fuel additions, but only by 9%.
Excluding the impacts of the GFC in 2009, additions of renewables have not outpaced fossil fuels since 1993.
An explainer about methods for accounting of the supply and consumption of energy.
In 2018, 83% of anthropogenic CO₂ emissions originated from fossil fuel combustion. 46% of this in 2017 was from only 11 economic sectors within 5 countries.
In 2019, annual electricity generation by fossil fuels reduced for the first time since 2015; the only instances in the past decade.
During 2016-19, additional wind electricity generation faltered, and that from solar slowed.
There is a perception that energy from solid biofuels is carbon-neutral, but this is not necessarily true.
