Save The World by Saving Energy

SAVE THE WORLD by saving energy in your home WHY YOU SHOULD CARE ABOUT ENERGY EFFICIENCY WE ARE NOT AS EFFICIENT AS WE COULD BE: DEFINITION: ENERGY INTENSITY A way of measuring efficiency. Determined by calculating how much it costs to convert energy into goods. A higher MJ/$ means it takes more energy to create a product. Norway is the least efficient 15 MJ/$ Energy Intensity by Country (Amount of energy in millijoules needed to produce one US dollar in value) 12 MJ/$ * MORE EFFICIENT 9 MJ/S United Kingdom----6.5 Millijoules per dollar Japan- 6.9 Millijoules per dollar Germany-- -7.6 Millijoules per dollar 6 MJ/S China 9.6 Millijoules per dollar United States- -9.8 Millijoules per dollar Netherlands- З МJ/S 10.2 Millijoules per dollar Iran--- 10.8 Millijoules per dollar Norway -- 129 Millijoules per dollar V LESS EFFICIENT Japan Germany Iran Norway China United States Netherlands United Kingdom WE USE MANY RESOURCES: Hydroelectricity, natural energy, and biomass are the only renewable 100% – resources that we use World's Energy Consumption Non-Renewable Resources 80% – Left in the World Oil 37% (Percentage remaining in yottajoules) Coal- 25% 60% - Nuclear 37% Natural Gas- 23% Coal- -25% Nuclear Power 6% 40% - Oil--- -23% Bio Mass- 4% Natural Gas- -6% Hydroelectricity- 3% 20% - Natural Energy------ - 1% 0% - Bottom line: we rely almost entirely on oil, coal and natural gas. Bottom line: our traditional sources of energy are dwindling. WE PRODUCE A LOT OF CO?: DEFINITION:CARBON DIOXIDE A gas that is produced by respiration, and burning carbon and organic compounds. Naturally present in air, CO2 is absorbed by plants in photosynthesis unless Tons of CO2 7 mil they become overwhelmed by too high of volumes.

By 2020, it is estimated to approach 10,000 million metric tons. Million Metric Tons CO2 10,000 9,000 8,000 7,000 6,000 5,000 1990 1998 2005 2010 2015 2020 WHAT IS BEING DONE ABOUT POOR ENERGY USAGE? DEFINITION : NEGAWATT CURRENT ENERGY LAWS A theoretical unit of power, representing the amount of power that is saved over time (measured in watts). Today, the majority of residential and commercial construction is done with energy efficiency in mind. Energy Independence and Security Act of 2007 (US.): This act plans for a gradual increase of energy efficiency in the U.S. by mandating minimal energy requirements. (Eg, 40-150 watt incandescent bulbs are being phased out during the years 2012-2014.) CalGreen (California): Applies to residential and commercial buildings. Mandates include: reducing water use, diverting construction waste from landfills, and inspecting buildings' energy systems. AMORY LOVINS Phase-out Incandescent Bulbs (Australia): A physicist in the late 1970s who coined the terms "soft energy path" and "negawatts." He believed that to meet energy needs, we should increase efficiency, instead of increasing energy production. Australia has completely outlawed incandescent lightbulbs since 2007. 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! Money Spent on Energy per Year Conventional Energy Saving Method/Machine Method/Machine $1.500 Wattage (of appliance) x Hours Used Per Day $1200 + 1000 Daily Kilowatt-hour (kWh) consumption $900 (1 kilowatt (kW) = 1000 Watts) TO DETERMINE YEARLY COST: $600 Wattage (of appliance) x Hours Used Per Day x Days Used Per Year] $300 + 1000 x 8.5 cents/kWh (Your Energy Cost) EXAMPLE: WINDOW FAN (200 Watts x 4 hours/day Each line represents the energy cost per year of the appliance, lighting, or insulation indicated in the color key below x 120 days/year) + 1000 = 96 KWh x 8.5 cents/kWh = $8.16/year APPLIANCES SOLAR POWER INSULATION Dishwasher Washing Machine Assuming you do 6 loads Solar Roof Panels Assuming you do 6 loads per week Attic Attic leaks can drain 50% of a home's heating energy Windows Calculations for San Francisco, CA per week Single pane vs. double pane windows Bill Before: $60 Bill After: $48 Cost to Install: $550 Savings/Year: $12 CO2 Saved: 1,654 lbs Bill Before: $71 Bill Before: $300 Bill After: $150 Cost to Install: $37,314 Savings/Year: $150 CO2 Saved: 36,072 lbs Bill Before: $1200 Bill After: $960 Bill After: $51 Cost to Install: $750 Savings/Year: $20 CO2 Savings: 3,020 Ibs Cost to Install: -$3,500 Savings/Year: $240 CO2 Saved: 720 lbs Bill Before: $35O Bill After: $75 Cost to Install; $20.000 Savings/Year: $275 CO2 Saved: -2,,500 lbs Boiler If half of U.S. households had energy-efficient appliances in their homes, it would be enough to save $150 billion annually and reduce CO2 emissions equivalent to taking 2 billion cars off the road!

EFFICIENCY Energy Conservation is an attempt to use less energy (e.g. riding a bike or turning off lights). DEFINITION : REBOUND EFFECT This idea takes into account the possible downside to energy saving. Energy Efficiency is using energy in an efficient manner (eg. using energy-efficient appliances, lighting, and home insulation). The more you save, the more you may find it affordable to use more resources (e.g. the lower gas costs that come from owning a hybrid car could prompt more 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? Incandescent CFL LED Cost: $2 $4 $40 Life Cycle: 1,000 hours 6,000 hours 10,000 hours Safety Overheats; has mercury Overheats; has mercury No hazardous materials Cons: Releases mercury Slow to light up Limited options, uneven lighting Pros: Inexpensive Recyclable Long lasting 119 If every houshold in the United States replaced one incandescent bulb with a CFL, we would have enough energy to light 3 million homes for a year. We would save $600 million in annual energy costs and prevent 9 billion Ibs of greenhouse gas emissions per year. Live Local · Search Local eLocal" Carbon Diaxide by Country: US.
