To put some figures on it:The big problem with using gas as base load fuel is, as smurf said, the rate that you go through it.
It is too versatile a fuel to be throwing through turbines to make electricity. Which then goes over the transmission system, with all it's losses to end up in the kitchen boiling water in a kettle or electric heaters etc. It makes much more sense to boil the water directly with the gas.
The other point is Gillard goes on about the carbon reduction is like taking 140mllion cars off the road. Well they wouldn't have to be taken off the road if they were running on gas. The whole transport industry could run on gas.
Like I said it is criminal to throw such a precious fuel through turbines to make electricity, they had better be sure of their science because if it is proven wrong they are doing Australia and the world a huge disservice
Australian fuel reserves:
Coal = 1,245,400 PJ
Gas = 138,280 PJ
Oil = 24,126 PJ (includes LPG and condensate)
Given that oil is limited (globally) and that gas is the only real substitute we have, it seems almost criminal to even consider wasting it to generate electricity.
There's also the economic factors. 40 years ago we used oil to generate electricity and heat houses. Then the world realised that oil is rather useful for all sorts of things more important than firing boilers and priced it accordingly. The same will almost certainly happen with gas as it replaces oil as fuel for vehicles etc. It will end up far too expensive to burn for electricity just as oil did.
Coal comprises a massive 88.4% of our fossil fuel reserves but only accounts for 42% of fuel consumption.
Oil comprises just 1.7% of our fuel reserves but amounts to 35% of fuel consumption. The math tells the story - this is a problem.
Natural gas is 9.8% of reserves, and comprises 23% of consumption as well as being the only real replacement for oil. Once you factor in the fact that most of our gas is planned to be exported, and that we need gas to replace oil in the future, then it's nowhere near as abundant as many seem to think.
Looking at the figures, it would seem outright crazy to use oil or gas in a low value application (baseload electricity generation) where coal could be used instead. It's not as though we can easily use coal at home in the kitchen or run aeroplanes with it once the oil and gas has all been used up.
