Offshore wind output surged 37% year on year, hydropower generation grew 21%, solar was up 20%, and onshore wind 6%. On the other hand, coal-fired generation fell 7% and gas output dropped 24%
double digit declines in coal and NG use were also present every earlier month of this year. Europe has by far achieved the biggest emission reductions in the world this year. 16% point market share drop for fossil fuels electricity since just 2023.
If batteries are charged by renewables, then counting the battery output as renewables is fine, as long as you don’t count the charging. Same for pumped storage.
The point though was that existing hydro can be enhanced because it runs at spare capacity. Compared to dedicated pumped storage projects.
