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 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 nonrenewable 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.)
