Today the global energy mix is made up of a diverse range of sources: biomass, coal, oil, gas, nuclear and a range of renewables including hydropower, solar and wind.
In 2020, the global primary energy mix was made up of:
- Coal: 27.6%
- Oil: 31.6%
- Gas: 25%
- Nuclear: 4.4%
- Hydropower: 7%
- Wind: 2.6%
- Solar: 1.4%
- Other renewables: 0.5%
This means that about 16% of our energy came from low-carbon sources: nuclear accounted for just over 4%, with the remaining 12% coming from renewable technologies.
Note that these figures do not include traditional biomass, which can be a main source of energy in low-income countries. This is because this source is harder to quantify and only commercially traded energy is included in this data.
