Lightbulb Energy Efficiency Lab Lesson Plan

By: Kevin Britton

Determining  your school or home's energy efficiency is based off of the amount of energy used  compared to the amount of energy available. Replacing an inefficient light  source with a more efficient one is arguably one of the most cost-effective and  simple means of reducing personal electric energy consumption. A big part of emerging,  international Cap and Trade  policies (see Glossary of Terms) involves the  phasing out of standard incandescent lights (the type of bulb you and your  ancestors grew up with) and replacing them with compact fluorescent lights  (CFLs) or even more efficient light-emitting diode (LED) technology.
