Imagine the possibilities. Imagine if people all over the world mobilized to replace one billion standard incandescent light bulbs with energy-efficient compact fluorescent (CFL) light bulbs.  What would that mean?  It would mean that those people would save money each month on their electricity bill.  It would make a difference to the environment - preventing greenhouse gases equivalent to the annual emissions of millions of cars. And it would reduce our energy dependency on other countries and on fossil fuels.  Learn how One Billion Bulbs got started.

One Billion Bulbs is part of a more comprehensive home energy initiative called the Energy Trek.  Energy Trek has a broad scope, covering not only lighting, but appliances, heating/cooling, wind/solar, and transportation. But the first and easiest "energy trek" you can start is the "lighting trek" - conserving energy by changing your light bulbs! The Energy Trek roadmap on lighting can help "lighting trekker" in their home. One Billion Bulbs is a community initiative where we can track our collective progress, both in the US and around the world, on our “trek” toward changing one billion bulbs.

Important Information for New Members of One Billion Bulbs (OBB)

In order to enable OBB members to take advantage of future Energy Trek facilities, all new OBB members (since May 1, 2007), along with their data, will be automatically registered in the Energy Trek program, as we previously explained on our sign-up page. As Energy Trek members, you will be covered by the terms of the Energy Trek Privacy Policy and Terms of Use. Energy Trek is an energy initiative of Pajamas Media, an internet media company.

Current Phase: Phase 4 Learn about our milestones

Our goal is to educate people about the cost-saving and environmental benefits of compact fluorescent (CFL) light bulbs so that individually they save money and collectively they bring about an environmentally-beneficial outcome.

  • Save Money - Compact fluorescent light bulbs typically consume 65% - 75% less electricity than regular light bulbs.  And they last up to 10 times longer than regular bulbs.  The bottom line is that you'll save money by replacing standard light bulbs with CFL bulbs.

  • Help the Environment - Most electricity in the U.S. is produced by coal-fired power plants.  The problem is that for every kilowatt hour of electricity generated by a coal-fired plant, the EPA estimates that 1.43 lbs of greenhouse gases are released into the atmosphere.  By switching to energy-saving CFL light bulbs, you lessen greenhouse gas emissions into the atmosphere.

No matter what your age, political leanings or worldview might be, we hope that you'll agree with us that it makes economic and environmental sense to take action. 

If, like most, you care about saving money or are concerned about global warming, please consider implementing the following action plan.

  • Learn More - Learn more about the benefits of compact fluorescent light bulbs. 

  • Change Some Light Bulbs - Buy some CFL bulbs at your local hardware store or buy them online

  • Sign-Up for a OneBillionBulbs.com Account - Sign up for a free account and record your purchases so that we can calculate your savings as well as the aggregate savings of everyone who participates in this site. 
An Appeal - Please. Please don't omit this step. In order for this site to be successful, we need your participation. Like most, you're probably busy. But your action counts. Your grand kids will thank you for it.
