Sierra,

The investment energy required to build a U power station and refine its fuel (I thought) was quite low. The figures for a fast breeder or a high flux reactor (like in a nooclar (to use the US pronunciation) power submarine) since they use highly enriched fuel might be the figures you have seen.

I used to get very grumpy about a tram extension in eastern Melbourne.

The Minister was doing a TV interview close to my office (overlooking the road) spruiking how environmentally friendly it was.

Blackburn Rd to Vermont, 'bout 3k's, rip out all the trees in the median strip of the road, put rails in the ground, wire in the air, automated crossovers to control cars, and run (what 40 tonne?) trams down these rails with two passengers and a driver.

EEEEEK. I will never pay back its carbon debt, let alone (using standard electricity in Vic) be better than the patrons taking a taxi to cover the 3km journey.

Yes, agree - consider the carbon investment for carbon saving projects!!!
