Change your Light Bulbs!
We have switched out most of our lightbulbs to LED bulbs.
What is LED? This is a great science lesson! http://electronics.howstuffworks.com/led.htm
So how can I save if the bulb is so expensive? This was an obstacle for me! We started by buying a few at a time. Now most of our lamps and room lights have LED bulbs. While this site also sells the bulbs I posted it for the information. We get ours at Lowes for a reasonable price. http://www.eartheasy.com/live_energyeff_lighting.htm
Here is a nifty site where you can plug in prices ect and figure out the savings over time with LED.
Do the research in your area. Check out your electric bill before and after you begin to use LEDs. We are!
