2. 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.

3. 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.

4. 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.

5. 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

6. 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.)
