Total global energy investment, 2017-2020

Notes

Investment is measured as the ongoing capital spending in energy supply capacity and, in the case of energy efficiency, the incremental spending on more efficient equipment and goods. The scope and methodology for tracking energy investments is available at https://www.iea.org/reports/world-energy-investment-2020/methodology. “Fuel supply” includes all investments associated with the production, transformation and provision of solid, liquid and gaseous fuels to consumers; these consist mainly of investments in oil, gas and coal supply, but include also biofuels and other low-carbon fuels. “Power sector” includes the capital spending on all power generation technologies, as well as ongoing investments in grids and storage. “Energy end use and efficiency” includes the investment in efficiency improvements across all end-use sectors, as well as end-use applications for renewable heat.
