The age of gas is finished.
I have some sympathy with this view, but are you going to nip into
your Tardis and go back to tell Thatcher not to build our energy
generating capacity on gas too? If you follow the web links that TNP
has been posting lately, it's amazing just how much of total grid
output has been coming from gas of late.
If the gas is finished, or if Putin turns the tap off again, not only
will the heating go off, but the lights will too.
I'm quite surprised that a fuel like Gas is being used up much faster
than what it ought be whereas coal is plentyfuel..

Gas power stations are much cheaper to build than any other sort.
No boilers etc. just a gas turbine. They can be quickly started too in
an emergency. (Thought this is undesireable)
Wrong on both counts. CCGT sets do have a boiler and a steam turbine on
the back and are in fact designed as fast start emergency backup as well
as continuous operation.- Hide quoted text -

Only if combined cycle.
Not many OCGT sets around...because of high fuel cost they are only used
in extreme '**** we are about to have a blackout, start the diesels
captain' sort of situations.
