You should look into how much energy goes into making Portland cement. It's stunning how much heat is required. Heat these days means oil in some form or fashion. Not to mention the rest of the CO2 produced in the process. This site claims about a ton of CO2 is produced for every ton of cement. If you're worried about CO2, concrete isn't looking much better than bitumen in a cradle to grave model.

C.A.R.B. (California Air Resources Board) made some claim about this a few months ago and I remember hearing about it on the news. They were talking about alternative mixes for "black" paint and they really turned out to be some ugly shades of brown or something like that.

right, so we can all go blind because of the horizontal light entering our eyes and frying our rods ... then no one will be able to drive (or do anything, thereby causing no further damage) and the world will be saved
^ this idea is far less loony

no idea why the hell people put jet black roofs on their house....I'd paint my roof white today if my homeowners assoc would allow me to. I'm looking at radiant barrier paint for the inside of the roof, but a white outside would be a huge benefit....I used a bright white TYVEK car cover for a while -- EXCELLENT at keeping the car cool!!
uh yeah right I stopped snowboarding and skiing becuz the snow is so bright white....

Is the energy secretary loony?
What about all the pollutants in petroleum based paint that would HAVE to be used for it to last any reasonable amount of time? Keeping it clean? I can think of 100 other reasons why this is a bad idea.
Sure this isn't a late all fools day joke?

Finally, clearer voices are being heard, and the technobabble from the left is being replaced with real science:
[Australian Senator Stephen] Fielding put to the [Australian climate change] minister three questions:
The wider significance of this episode is that it is the first time a Western government has allowed itself to be drawn into debating the science behind the global warming scare with expert scientists representing the "counter consensus" - and the "consensus" lost hands down.
We still have a long way to go before that Copenhagen treaty is agreed in December, and with China, India and 128 other countries still demanding trillions of dollars as the price of their co-operation, the prospect of anything but a hopelessly fudged agreement looks slim. But even a compromise could inflict devastating damage on our own economic future - all for a theory now shot so full of holes that its supporters are having to suppress free speech to defend it.

- How, since temperatures have been dropping, can CO2 be blamed for them rising?
- What, if CO2 was the cause of recent warming, was the cause of temperatures rising higher in the past?
- Why, since the official computer models have been proved wrong, should we rely on them for future projections?

Yeah.. this might not be that bad of an idea. Its a lighter color (you can color concrete anything you like), and it lasts a lot lot longer (less paving projects in the future). Actually other countries use concrete for their highways instead of asphalt, but maybe cuz asphalt is not as available.
