Amory Lovins of RMI has presented evidence linking energy efficiency with improved profits at some major corporations. There are now sustainability MBA programs at institutions like the Presidio College that are training the next generation of managers and executives. This profit oriented demographic will uses their newly acquired efficiency paradigms to drive the more forward thinking corporations towards sustainability as a competitive strategy. And being less competitive will quickly drive the other corporations towards efficiency. As Lovins says, "We will change their minds or their managers."
Companies like FiberForge will be cranking out the new ultra-light, ultra-strong materials to meet an ever rising demand. A concept I would find conceptually appealing would be generating some of those carbon fibers from CO2 emissions. To sequester carbon within the industrial materials that will reduce the CO2 emissions has a kind of intellectual symmetry that is very satisfying.
