Just in case you have not joined the wave. Replacing incandescent light bulbs with Compact Fluorescent Light Bulbs or CFLs can save you lots of money. 90% of energy used by traditional incandescent lightbulbs is wasted as heat.
How Energy Efficient?
How does a regular incandescent bulb compare to a compact fluorescent one? CFL’s use about 66% less energy and last about 10x longer. The estimated amount of savings is up to $39 over the life of the CFL. PG&E advertises that replacing a 100 watt incandescent bulb with a 25-watt CFL will save at least $90 in energy costs over the life of the bulb. A typical house may have over 60 light bulbs.
