Energy Efficiency by 2041 (Salon: Michael Klare)

"...one crucial approach to energy consumption in 2041 will surely be efficiency at levels unimaginable today: the ability to achieve maximum economic output for minimum energy input. The lead players three decades from now may be the countries and corporations that have mastered the art of producing the most with the least. Innovations in transportation, building and product design, heating and cooling, and production techniques will all play a role in creating an energy-efficient world."
