DEFINITION : NEGAWATT A ar nd ing the amount of CURRENT ENERGY LAWS ty cansevalion Today, the majority of residential and commercial construction is done with energy efficiency in mind. 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. Since so much energy is used in the residential sector, conserving energy in your home is an easy and effective way to reduce the world's energy consumption INVEST IN ENERGY-EFFICIENT SOLUTIONS Cost of Conventional versus Energy Efficient Appliances, Lighting, and Insulation CALCULATE YOUR OWN ENERGY USE!

EFFICIENCY DEFINITION: REBOUND EFFECT Consenvation is an oftemot to use less energy (eg riding e bke or tuning off ights) ty Elficiescy is using energy in an efficient manner (eg using energy-efficiest appliances ighting and home insulation) This idea takes into account the possble downside to energy savirg The more you save the more you may tind it attordable to use more resources (eg the lower gas costs that come from owning a hybrid car could prompt nore driving) INCANDESCENT/CFL/LED LIGHTING FACE-OFF Energy-efficient lighting is one of the easiest and most affordable ways to reduce your energy usage. There are many options, but which should you choose?

We would save $600 million in annual energy costs and prevent 9 billion Ibs of greenhouse gas emissions per year. eLocal.com Live Lecel Search Loc ecal Carton Dae y Country wwwmdgun US Poputo w Worte Enr Corti www inng Word ne S whegobaed.cationpmedarg Certon Diade trt wnt om Windw wewcandercom Erergy independerce nd Security Act hommlocgor w ay ly County Carton Dai www.ktoneryre .com COP Poaon wceonga Irtion wwbuldsclcom Scar Parw con hcndcent Phae Out wwcintechangegoRI Applances wwwtego trerg wwwtpcon/atetcal A wwldhclaro Incandescent/CFLAED Face-ot wngercom Gnde Eficienoy apaeeggov Eherg Sa werergtargo eidental Homwn Eregy Uhage wpagor Gorman Canada

Our energy resources are dwindling and we produce a lot of CO2 emissions. The future depends on our ability to leverage renewable resources like hydroelectricity and natural energy.
