Over the full year 2017 renewable energy sources excluding
large hydro plants represented 31 % of California's in - state electricity generation.
Australian coal - fired electricity is almost the cheapest power on the planet — rivalled only by
some large hydro plants.
Not exact matches
Newfoundland and Labrador is constructing the massive Lower Churchill hydropower facility, and Manitoba is expected to begin building the Conawapa Generating Station, which would be the
largest hydro - electric
plant in the province's north.
Aaron Kreider, a Web developer in Philadelphia who runs a site called the Energy Justice Network, a nonprofit group that supports clean energy and advocates phasing out all nuclear, fossil - fuel,
large hydro and biomass
plants, said he uses the CARMA data to supplement information on power
plants in the United States.
When finally completed, it will stand as the world's
largest generator of
hydro - electric power, with a yearly output equal to that of fifty million tons of coal or fifteen nuclear power
plants.
E. g. if the sunlight is collected in outer space by
large but practical thin plastic mirrors, it can be directed to any place on earth, preferably near existing
hydro - electric
plants, so that it would not be necessary to greatly increase the existing electric grid, all without any really new technology.
That opened a downstream channel
large enough to flow 13,000 cfs through Oroville's Hyatt Power
Plant's
hydro turbines, barely keeping up with low inflows (DWR 2017e).
Nuclear power
plants require enormous amounts of fresh water to operate — they are on rank 3 on the
largest water footprint of energy sources after
hydro - electric power (obviously) and shortly behind coal — leaving all other energy sources way behind, including gas, wind, solar, etc..
Power variability from renewables could be addressed through storage,
hydro,
larger power networks, existing nuclear baseload, and lastly through existing natural gas
plants.

But then I went on to envisage, at least in my own mind, a time when
large fossil fuel generators had all closed own — mainly in order to avoid ruining our one and only habitable planet — and that the 24/7 power supply would be a mix of Solar PV, solar thermal (eg CSP), wind and the lesser sources such as
hydro, tidal, geothermal etc having taken over the complete electricity supply — especially since Australia doesn't have, and is almost certain never to have, nuclear fission
plants.
Several other counties in the EU, do however have very
large hydro capacities (there is 30GW in Norway alone) and some of these reservoirs are now being converted to pumped storage; e.g. Germany's Thuringia State has identified 13 potential sites, including 3 existing dams, for constructing pumped - storage
plants that would total 5,130 MW.
