Meanwhile those of us advocating sustainable generation are not

and thus your point is moot.

So where does the rest come from?

Not enough land for biofuel.
Not enough sun for solar.
Not enough estuaries for wave power.
Not enough volcanoes for geothermal.

What's left?
Fossil or nuclear. for the last 80%

You are again trying to pose a simplistic either or question, but
things are rather more complicated than that.

For example, wave generation would not be done in estuaries, it
would be done out at sea. You didn't mention tidal currents. There
is a long list of things.



Out as sea? so block half the north sea with hufely expensive bobbing
platforms for a few megawatts? How to build them? what cost? how to get
the power ashore?


Insane. You don't have a clue, do you?


Do the maths. Do the numbers.stop listening to the 'well it works on a
small scale so it has to be The Answer' brigade.

The truth is there is NO answer at all.

Its a stark choice between a rapidly falling standard of living, climate
change out of control or nuclear power. Take your pick.

Other countries have slightly different alternatives: We don't.
