EXPERIMENT 10:

CHECKLIST FOR ENERGY —
EFFICIENT LIGHTING

How much energy is used to light your home? Probably,
about 2000 kilowatt-hours of electrical energy each year. Your
local electric power plant burns about 150 gallons of oil (or over
¾ ton of coal) to generate the electricity.

With this much energy “going up in light,” it makes good
sense to learn to use lighting efficiently. This simple lighting
checklist will give you a head start. Walk through your home with pencil and paper in hand — and see how well the lights in your home stack up. Tell your parents about your findings.
