Dear Armchair Critic,

You write "I bet they still enjoy all the comforts that burning coal gives though."

But they want those comforts to come from renewable energy. What is wrong with that old boy?

SR you're not really stupid enough to believe that the renewable energy contribution to our power supply could be ramped up from 5& to 100% in less than 50 years.

All this bull dust about 2030, or even 2050 is a con, & anyone who believes it is even possible, let alone desirable is in the words of the drink driving add, "a bloody idiot".

Dear Hasbeen,

Adam Morton, in The Guardian, tells us that -
"Clean energy set to provide 35% of Australia's
electricity within two years. The renewable boom will
end without a national policy to encourage future clean
investments, industry warns."

The Clean Energy Council Chief Executive, Kane Thornton
said, "the industry was still on track for 50% clean
energy before 2030..."

Is it true that it takes one hundred tonnes of coal (more or less) to make one tonne of steel for a wind tower ? And probably something similar to make one tonne of cement as well ? I suppose someone's worked out how much CO2 that produces ?

I don't know how many tonnes of cement and steel go into one wind tower, but I'm also told that each tower needs ten metres of concrete footing to keep stable.

I wonder how much CO2 is produced in the production, and maintenance, of one wind tower, over its working life of twelve or fifteen years ?

And of course (since it's the purpose of wind towers) how much CO does it save ?

Am I allowed to ask such questions ? More to the point, will I get an answer ?

Nah.

Joe

Joe,

I've got some questions for you.

Aren't our remaining coal power stations ageing
and breaking down?

Building new coal power stations? How expensive are they?

How many years do they take to build?

Aren't they highly polluting?

Is coal really a match for clean renewable energy?

Foxy you are at it again. Quoting the Guardian is not on in polite company, it is just as bad as quoting the conversation or the ABC in general.

Yes the Clean Energy Council would say that, after all they are lobbyist for windmills & ripping off the taxpayer to build their monstrosities.

You had better hope they are wrong, because the next state to be sitting generally in a cold dark house, waiting for the power to come back on is yours. Victoria & South Oz both go dark without Queensland coal fired power & Tasmania hydro. So take your pick. We can burn coal, or dam the rivers, cause wind won't do it.
