Re: @ITMA
But that is assuming of course that your "electricity generation" is typical of the whole planet.
This source says somewhat different:
https://www.iea.org/data-and-statistics?country=WORLD&fuel=Energy%20supply&indicator=Electricity%20generation%20by%20source
"World electricity generation by source in 2017. Total generation was 26 TWh."
Coal (38%)
Natural Gas (23%)
Hydro (16%)
Nuclear (10%)
Wind (4%)
Oil (3%)
Solar (2%)
Biofuels (2%)
Other (2%)
Given that in their figures coal accounts for the majority (38%) I seriously doubt that between 2017 and now it has dropped by that much (down to just 4%).
