But don't you see? It's the extra layer of government, and the extra taxes (although they'll happily spruik for their constituencies and special interests to get tax payer funded "compensation"), and the jobs that will be lost, and the end of the economy as we know it.

What I wonder is, how is it then that the European Union, which has arguably had an even more flawed ETS for 6 years now, seems to be surviving?

Including in Germany alone, the directly attributable creation of 230, 000 plus jobs in the renewable energy industries (R&D, manufacture, sales - domestic and international, and installation of wind, solar, biomass, tidal technologies), and creation of an additional, invaulable income stream to (especially) farmers, from energy production.

You know, from all those solar panals and wind turbines they've planted in the paddocks where the livestock graze.

Good grief. Who knew? The sun shines and the wind blows and the tide goes in and out in Europe!

And they're (SHOCK! HORROR!) progressively decommissioning nuclear power stations, as more renewable energy sources come on line.

Oh well, guess we should just get used to a nice balance of trade deficit with the Euro zone over the next few years, importing technology and know-how, what with having sold off, closed down and driven out most of our world class renewables R&D technologies and intellectuals, to everywhere else during the last two federal administrations.

No, Joshua, they're not haters, they're just humans stuck in the oldest human dilemma. Having to change their minds about a belief they hold dear, rather than admit to a mistake.

Like King Canute trying to hold back the tide, this is (I hope!) their last hurrah. Just as the GST became the inevitable "tax reform" we had to have, so will the ETS and/or carbon tax be part of the new reality of the carbon constrained and oil depleted future of the Australian and global economy.

The sooner we all face this fact, regardless of our belief, the sooner we can start getting results.

Green makeoever to create jobs

I don't read the papers every day, not even online, but I reckon this got lost in the mainstream noise generated by the financial gurus running around like chooks with their heads cut off. (Thanks to Kwoff for the heads up.)

UNIONS want a "green revolution" to sweep the country's homes, saving more than $400 on annual household electricity bills.

They have called on the Federal Government to pay for a mass retrofitting of homes to slash electricity use.

Homes would be kitted out with insulation, double glazing and smart appliances at a cost to the Government of $5500 apiece. ...

Not a bad start Sharon, but a solar hot water system and/or grid connect solar system as well, would be even better.

Our carbon footprint - we're megawatt performers!

Our 1.1kW grid connect PV system ticked over the 1 megawatt hour of energy generated a month or so ago, a bit under a year after we installed it under the former Howard Government's solar rebate system.

Based on figures from DEUS (NSW), that means we've saved more than 1 tonne of greenhouse gas emissions from going into the atmosphere. Woo Hoo!

It hasn't reduced our power bill by that much, because our supplier has brought in a "daily connection" charge, so the excess we've produced above our household demand and fed back into the grid, is chewed up by that. (Thanks Morris, can't wait to see how our environmentally minded privatised electricity providers will handle the greenhouse challenge, and pass that cost along.)

Anyway, reducing our electricity bill wasn't the motivation for getting the system installed, we've always (as much as the budget would allow) factored in reducing* our carbon footprint in our lifestyle activities and choices, so this was more about doing our bit to save the planet, than saving money.

This year we installed a solar hot water system. It came online when we had unseasonal rain, so we had to fire up the booster for the first two weeks, but the offpeak meter has only ticked over 14kW or so since it was installed more than 4 weeks ago. It will be interesting to see how much more this will bring our household carbon footprint down.

So, all this got me wondering. Instead of building new coal fired or nuclear powered stations to satisfy "demand", how about we (collectively) reduce waste, improve efficiency and increase household market share of renewables to reach the 60%-90% greenhouse gas reduction target?

It cost about $13,000 to create a "point of use" 1.1kW power station on our roof. It produces about 1MW of power per year, sends some juice back to the grid, and forestalls about 1MW of greenhouse gas per year going into the atmosphere from our household activities.

There are approx. 1.6 million private dwellings in Victoria (VIC) and 6.6 million in Australia (2001 census: Separate house and Semi-detached, row/terrace etc.). The new coal fired power station mooted for VIC is going to cost a minimum of $150 million, apparently a nuke could cost USD$1B, ... can someone please do the math?

As the Stern Review and Garnaut Climate Change Review have already pointed out, the economic "ROI" bean counting, will soon be far outweighed by the environmental, social and economic costs of doing nothing.

The sooner we (collectively) start, the cheaper the solutions are, and the faster we get to our 60%-90% of 1990 greenhouse gas emission levels target. (And maybe save the planet.)

And don't use "China and India ... blah blah blah ...", as an excuse. We were primarily responsible for our greenhouse gas emissions in the past, we're responsible for our contributions now, and we'll be responsible for them in the future. Time to collectively get to work, because the clock is ticking.
