While it is true that about 58% of "hydro" (as the Upper-Canadians like to call it) is produced from hydroelectric sources, the majority of the rest is produced with some variant of coal/oil/gas fired plants with a smattering of nuclear and wind in there for completeness.
Oh, and lets please not pretend that hydroelectricity is 0-impact... it might be _after_ operational, but certainly does a lot of damage to the environment to get that way.
But back on topic, TDI engines are awesome.
