My contribution to renewable energy discussion (Chris Davies MEP) on LibDem Voice:-
Why does no-one mention hydroelectricity these days? Look at the success
of Kielder Reservoir – and it also provides leisure facilities and a
soulution to drought. According to US Dept of Energy figures, (Wikipedia
– cost of energy by sources), average dollars per M/Wh, hydro costs
89.9, onshore wind 96.8, offshore wind 330.6(!) solar 156.9 and biomass
120.2. Wave power is estimated at 611(!!). So hydro really is the way to
go, for renewable energy. Regretfully, critics who aren’t interested in
pollution problems would point out that most conventional power sources
are cheaper than this, particularly gas.
It was suggested that (a) Hydro was not the best resource for Britain, space wise/availability of water with a sufficient fall in gradient, and (b) hydro in the Amazon was associated with significant methane outgassing.
