Thanks for inviting me back to the Café.
When I was working on ideas for my blog, a good friend sent me the following quote from a Hopi elder: “We are the people we have been waiting for!” 
That quote got me thinking about all the problems we currently face and I decided to focus on one problem for this blog — global warming — because the solutions include simple, individual actions that a person can take immediately (no waiting).
So, you ask, what can one person do right now to help reduce global warming?
The answer is simple: Change one light bulb in your home to an energy star qualified bulb or fixture. This action is the equivalent of not driving your car for more than two weeks! Save energy and help protect our environment.
According to the ENERGY STAR website, you can save the most energy and money by replacing your highest used fixtures or the light bulbs in them with energy-efficient models. The five highest-use fixtures in a home are typically the kitchen ceiling light, the living room table and floor lamps, bathroom vanity, and outdoor porch or post lamp.
If every American home changed out just five high-use light fixtures or the bulbs in them with ones that have earned the ENERGY STAR, we could prevent greenhouse gases equivalent to the emissions from more than 8 million cars.
ENERGY STAR qualified lighting provides bright, warm light but uses at least two-thirds less energy than standard lighting, generates 70 percent less heat, and lasts up to 10 times longer.
So what are you waiting for?
