Yes, it is. It's even more "green" than a hydro dam, which typically generates a shit-ton of methane for a few years after completion.
Hydro is the 3rd best after Nuclear and geo-thermal, but there are literally NO more large hydro sites that would be viable. So... no more hydro power can come on line, realistically.
Is that really effective in generating electricity?
