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.

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.

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.

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.)
