The Prime Ministerial taskforce on greenhouse emissions will deliver its report next week, against a background of the price of electricity going up ---wholesale electricity users are being quoted price increases of between 30% and 120% when renewing contracts. The reason is that there's not enough water to help generate the electricity from conventional coal-fired power plants. If the existing disconnect between the water supply and demand continues, we have power cuts.
This disconnect is happening in South East Queensland, where two of the largest coal fired power plants are running at 80 per cent capacity at the moment simply because there's no water to cool the plants and generate the steam that is needed to drive the turbines. So the Queensland Government's putting in a $1.7 billion pipeline to take recycled water to the coal fired power plants to keep generating electricity. Isn't that a public subsidy?
It's just the drought the state politicians say. What if it were the effects of global warming as well? What if we are getting a glimpse of our future? If so, shouldn't the money be better spent differently? Some say--the Nationals-- we need to build more dams and build more coal-fired power stations. I reckon its farewell to cheap electricity, no matter what.
The task force is expected to recommend the establishment of an Australian marketplace for trading carbon emissions. Will this start a much needed revolution in Australia's energy sector? Or will it be just a tentative toe in the water?
A carbon trading scheme would work by placing a cap on Australia's total greenhouse emissions, set lower than our current rate of pollution. Just as governments now issue permits for fishing to limit the number of fish pulled out of the water, polluters like power stations would be given permits which would limit how much they're allowed to pollute. The permits could be traded. Those who couldn't cut their emissions enough could buy permits from green power companies.
So there's a certain amount coal fired power stations allowed to pollute and then they have to pay a price. The price is the dollar amount that they pay for each tonne of carbon dioxide they emit into the atmosphere after they have exceeded their cap. That's the point at which your penalties begin. What level should the cap be set and kind of penalties are the issues?
Tim Flannery argues that what is needed is a significant cap on greenhouse gas emissions that will force electricity suppliers to go to renewable energy sources and natural gas in order to source quite a substantial amount of the electricity they sell. A cap that will begin the transition to a carbon-free economy. Consequently, the politics will be around the extent of the cap---whether it is set at $20 per tonne of carbon emissions or $40-$50 per tonne of carbon emissions.
Flannery says the latter figure is what is required:
I think it probably should be around $50 per tonne. Working group three of the intergovernmental panel on climate change did modelling and $50 a tonne gets you significant reductions and that would equate to about a doubling of the wholesale price which would be about maybe 30 per cent of the retail price. So the bill that you and I pay might go up 30 per cent which sounds like a lot but when you think about it if you can't make 30 per cent efficiency gains in your house I don't know, there's something wrong. We all waste a lot of electricity and I think there's no doubt that most of us can make those sorts of cuts.
Will the PM's taskforce recommend that the level of the cap be driven by considerations of reaching the threshold of dangerous climate change? Don't we need to do that to avoid overshooting the threshold and propelling us into a much warmer world? Or will it make major concessions to the energy intensive companies?

My Electricity bill at home is currently around $1500 per annum so 30% is a large increase.
I wonder if we put as much gusto into saving power as we do water. Say if we saved 20% per household. Would this after a period of a year cause the prices for power to rise 20% or so to compensate. Given that the power supply is more economically driven than the water supply (at present)
