Energy Independence and Security Act of 2007 (LUS) This act plans for a gradual increase of energy officiency in the US. by mandating minimal energy requirements (Eg, higher minimum fuel economies for passenger vehicles and phasing out the use of incandescent ight bulbs) CalGreen (Calfornia): Appies to residental and commercial buildings Mandates include reducing water use, diverting construction waste from landfils, and inspecting buildings energy systerrs AMORY LOVINS A physicist in the lale 1STOS who coned the tems "soft erergr pelt and secavatis" He beleved thet to meet ereroy needs we should Increase efficiency instead of increasing enery production Phase-out Incandescent Bulbs (Australia): Australis has completely outiaved incandescent ightbulbs since 2009 WHAT STEPS CAN YOU TAKE TO BE MORE ENERGY EFFICIENT? In the US alone, buildings account for 72% of electricity consumption.

We would save $600 million in annual energy costs and prevent 9 billion Ibs of greenhouse gas emissions per year.
