Energy Efficiency of Motor and Appliances Donovan Sweet Matthew Feeney

Compact Fluorescent Light Bulbs The energy saved by switching to CFL’s in 2007 could light up a city the size of Washington D.C. for 30 years. http://farm4.static.flickr.com/3357/3192952873_99474b7cd4.jpg

CFL’s Continued The average ENERGY STAR bulb is designed to last over 7 years based on typical household use. It takes 10.3 mg less mercury to produce a CFL than a incandescent bulb. http://www.wycokck.org/uploadedImages/Departments/Air_Quality/cfl-recycle.jpg

More CFL’S !! Changing to these bulbs would be the same as planting 2.58 million acres of trees in terms of greenhouse gas removal. http://hoagland.org/photos/OR/OR113.jpg http://www.geocities.com/Heartland/Meadows/5741/pic/frgdist.jpg

Solar Charged Lawn Mower Gas Lawn Mower Consumes an unlimited resource (the sun). Lower noise levels The brushless motor requires no maintenance and has a longer life Consumes a non-renewable resource (gasoline) Noise pollution Ongoing purchase of gasoline Requires constant maintenance on the motor

Solar Powered Lawn Mowers It’s estimated that a solar powered mower creates at least 85% less CO2 in comparison to a petrol mower. (Maybe you have seen the figures, which they quote, that a single 2 stroke petrol mower emits, in just one hour of use, the equivalent volume of forty late model cars.) http://dailyhomerenotips.com/2008/04/16/solar-power-lawn-mower-part-1-no-more-excuses/
