I know an engineer at BNFL. He said if they built tidal turbines from Devon to South Wales they could power the whole country, but it would destroy the coast for miles and quite a way inland for the infrastructure so it won't happen. It does show how much energy is out there for exploiting, I think tidal turbines are the answer. Incidentally, BNFL have a load of ready to go Bristol Proteus and Olympus engines, not sure which version. They can use them for quick power generation if the grid has a big loss, but they've never been used, only tested. I have no idea where.
The problem with almost all renewables is they can't be relied on to provide the power when you need it. Solar isn't any good at night. Wind and Wave aren't any good on a calm day. Tidal only works twice a day. There is no simple way to store the amounts of energy required between when it is cheap and easy to generate, and when it's actually required.
I can only see the electric cars thing making the supply worse. Everyone is going to want to charge their cars overnight so they can use them the next day. No solar at night. So on calm winter days you're going to need something to supply the base load overnight. If it can't be coal or gas, then that only leaves nuclear.
Thing with the nuclear plants they love the night time use,
It costs lots of time waste of energy and not good for the reactor,
Why years ago when these came online, people where encouraged to use power at night,
Economy 7, who remembers that. Stick your washing machine on at night and heat your hot water from the emerson heater at night and we will give you cheaper leccy.
A nuke reactor runs best at a constant,
Takes time to throttle the reactor back off peak and the same throttle it up at peak.
They hate it and so do the energy companies that run them.
With most house hold appliances now very more energy efficient,
Silly councils turning street lighting off at night, its does not help or save money,
So charge at night aint a bad thing.
Funny was thinking back to this type of conversation or topic, 20 odd years ago when all us
On these forums, was told film cameras are dead and the end of film.
You all have to go digital.
Blimey the forums back then was very much like this topic.
Those saying it would not work not got the quality I'm staying with film.etc etc.
To expensive poor battery life, memory not big enough. Pictures won't last.
The things coming out was very much like lots of negatives we see on this topic.
Look 20 years on and how digital cameras have changed things.
