This interactive chart shows the share of primary energy that comes from hydropower.
Note that this data is based on primary energy calculated by the ‘substitution method’ which attempts to correct for the inefficiencies in fossil fuel production. It does this by converting non-fossil fuel sources to their ‘input equivalents’: the amount of primary energy that would be required to produce the same amount of energy if it came from fossil fuels. We look at this adjustment in more detail here.
In 2019, around 7% of global energy came from hydropower.
