Americans make up less than 5% of the world population, but consume 25% of the world’s energy?
Did you know….

• Energy Efficiency refers to using technology that requires less energy to perform the same function.
• Conservation is behaviors that result in using less energy.
Energy Efficiency vs. Conservation
4
• Heating & Cooling – 45% of a home’s total utility bill goes to heating and cooling– Manage the thermostat– Insulate the home– 1/3 of heating/cooling loss
happens through windows– Landscape to block wind and
provide shade
Energy Efficiency
5
• Appliances – accounts for 24% of the total utility bill– Energy efficient appliances
may be more expensive, but save $ in the long run
– ENERGY STAR® appliances– Read the Energy Guide label
Energy Efficiency
6
• Lighting– accounts for 10% of the total utility bill– Fluorescent bulbs use 25%
less electricity compared to incandescent bulbs and last 8-12 times longer
Energy Efficiency
7
• Water Heater– accounts for 13% of the total utility bill– Use less hot water– Lower the hot water thermostat– Purchase a new hot water
heater
Energy Efficiency
8
• Transportation– Americans spend more than $2,000 on average per year on fuel for their cars.– See page 4 on your handout for
ways to save gas.
Energy Efficiency

• Reduce the amount of waste you produce
• Reuse when possible
• Recycle
• Strive for sustainability: using energy without compromising the needs of future generations.
