[Greenbuilding] reduced energy use in USA

This sounds overly positive compared to other numbers I¹ve heard in the last
2 years. Emissions are down‹I¹ve heard generally around 4% year over year,
and it¹s mostly from industrial capacity reduction (recession).  But the per
capita could be well improved. Our economy is plenty more efficient than it
was in the 70s‹I¹ve seen numerous studies about it but can¹t quote them
off-hand. And given our population growth trends over 40 years, the per
capita numbers could skew positive.

You¹d like to think this is inherently b/c  people have gotten on board‹and
as Energy Star and other programs have matured this last decade, we¹ll see
nice improvements in per capita numbers this coming decade--but
unfortunately it¹ll be primarily b/c of the recession. Not only jobs, but
pollution is also offshoring.
