Hydro is not possible in most locations. Diversification is important, but each region must have its own 99.95% reliable power sources.
The national grid cannot provide power beyond a few hundred miles without major losses in power. If you look at Quebec, as an example, they lose between 20-40% of their power in transmission because the hydro dams are so much further north than the population centers.
- kragen 7y ago"Cannot" and "does not" are not the same thing; existing 735kV lines in Québec have losses in the 5%–8% range, and new HVDC designs can lower the losses even further. HVDC transmission is potentially economical even at transoceanic distances — thousands of "miles", if you insist on using poorly defined units from the Roman Empire. https://en.wikipedia.org/wiki/Hydro-Qu%C3%A9bec's_electricity_transmission_system https://en.wikipedia.org/wiki/Hydro-Qu%C3%A9bec's_electricit...
