Even so,
hydropower output would have had to grow by almost 40 % if it were to have displaced the increase in coal - fired power generation, an unrealistic prospect regardless of the weather.
The main reason was that growth in renewables and nuclear power could not keep up with increased electricity demand, even though some sources have cited a drought - induced drop in
hydropower output as a factor in the rebounding coal consumption.
Given that Southern China now faces power shortfalls due to drought - induced lower
hydropower output.
This will reduce
the hydropower output during the melt season.
That paper claimed Jacobson's study had a large modeling error on
hydropower output.
After all, preparing for floods means lowering water levels in the reservoir to allow for extra water, resulting in reduced
hydropower output.

output of Norway and Sweden.
In this model, local governments and grid operators can coordinate the
output of independent solar arrays and wind farms — which operate intermittently and at different hours — with
hydropower, biogas, and other low - carbon resources, thus simulating the
output of a 24 - hour power plant.

hydropower, biofuels, solar and geothermal power — made up 17 percent of total
output, compared with almost 63 percent for fossil fuels.
Hydropower provides clean and virtually carbon - free power, but is expensive to build, and its
output varies by season and by year.
