I am an advocate for energy efficiency. In 2004, my neighbor told me about energy efficiency (compact fluorescent) CFL light bulbs. Since then I have bought all energy efficiency light bulbs and replaced all of the light bulbs in my house. In addition, my workplace also replaced all of their light bulbs to CFL’s even though they are more expensive in the short term but long term they realized they were saving money because the bulbs lasted longer and used less electricity. If my neighbor did not tell me about CFL’s, i would not have made this change.
