Good resource: An Illustrated Guide to the State of Sustainability (US numbers)
Some key snippets (quoted):
- Commercial and industrial efficiency is something that companies are taking more seriously. But the fact is, we waste around 85% of the energy produced in the U.S. And we’re not getting much better.
- Vehicle emissions are growing slightly. Last year, the Obama Administration brokered aggressive fuel standards for trucks and cars that will increase the average efficiency of the nation’s vehicle fleet to 54.5 mpg by 2025. But even with more consumers thinking about fuel efficient transportation, automobile emissions rose in 2011.
- U.S. renewable electricity is increasing steadily. Renewables like wind, solar, geothermal and biomass still make up only a small part of our electrical mix. But they’ve been growing at steady rate. Assuming consistent tax incentives are in place, that growth looks like it will continue.
