A hopeful Friday note: a significant downloadable report (PDF) from the Swiss Federal Institute of Technology. It was just brought to my attention, but it’s from 2004. Its message bears repeating: energy efficiency/technologies have the potential to dramatically reduce energy use while supporting economic growth.

This European agency estimates that the E.U. could accommodate a 65 percent increase in energy services by 2050, yet simultaneously use two-thirds less energy than today. In the U.S., the estimate is that we could reduce energy demand to one-sixth of our use today through more efficient technologies.
