The environmental problems are major only in the eyes of the deluded who
would rate the welfare of a minority of animals much higher than of the
majority of humans and who are so blinkered that they cannot accept that
if global warming continues unabated the wildlife is likely to suffer
worse as well.
But unlike the vagaries of wind tide is almost totally predictable and
as the tide times vary round the UK it wouldn't take many schemes to
provide continuous 24 hour cover with probably less than 50% variation
between maximum output on spring tides and minimum on neaps.
Unnecessary with just a few barrages but Loch Ness would be a poor
choice for pump storage which is best arranged around a high reservoir
rather than something almost at sea level. (And in the wrong place
anyway. Scotland currently has a surplus of electricity and the
Highlands are far better suited to hydro schemes.)

It shouldn't be forgotten that these schemes are not totally green.
Taking out all the tidal estuaries in England and Wales would have major
impacts on bird life, and that might make them politically unacceptable.
Fascinating. Which rivers do you think would make good places for a
tidal barrage? The Severn is obvious, with that enormous range and the
large size. The Dee seems to have a reasonable range, the Mersey is
full of shipping, Morecambe Bay would need a 10 mile barrage, The Solway
is almost in Scotland where you said we don't need it, the Humber looks
pretty good, maybe the Essex Blackwater? But isn't that about it?
I was kidding. I know Loch Ness is only 50M up, (and is in fact the
lower part of a pumped storage system already) but I don't know anywhere
that could make a storage scheme big enough.
The real problem is - what do we do about the Chinese coal-fired power

Reduce our demand for chinese goods ?

Exactly. In the end it come to our wanting to buy for the cheapest

The Chinese want to have the same standard of living as the rest of the
world, so they will continue to produce stuff whether the West buys it or
