Light pollution is a reference to the photons created by artificial sources which are "wasted" or otherwise have lost their direct use and instead escape into the night. Gazing across any nighttime cityscape, millions of point sources of light can be identified, each contributing to the regional light pollution, photon-by-photon. Is something as benign as flipping on the lights at night really a source of pollution on par with the myriad of chemical pollutants we face on a daily (or nightly) basis?

Taking advantage of natural lighting can be a healthy, eco-friendly way to light your home without spending a fortune on electricity costs. What are design elements that we can incorporate into the modern home to maximize natural lighting?

You don't have to be a company director or wealthy to create a healthy and eco-friendly workplace because small efforts can make all the difference.

Even though they are considered dinosaurs in the modern lighting world, incandescent bulbs and the warm light they create still have a wide appeal. So how can we reconcile energy-gulping incandescents with a greener home?

Did you know the energy use of the average household in the U.S. emits twice the greenhouse emissions of the average car? By simply replacing the most frequently used fixtures/bulbs you can make an impact and help fight global warming.

Energy Star compact fluorescent light bulbs (CFLs) use less energy and last up to 10 times longer than standard incandescent light bulbs....

Replacing your five most frequently used light bulbs with Energy Star qualified bulbs can save more than $65 a year in energy costs....

Compact florescent light bulbs have garnered cries of disgust from consumers since they were introduced thirty years ago. These bulbs were too big for some lamps, expensive ($20 or more), flickered and buzzed, and had poor light quality (a cold dimness). But technology has caught up with customer demands for energy-efficient bulbs that shine warm, bright light similar to standard incandescent bulbs.

In California, lighting accounts for approximately 28% of home electricity use. As a nation, we spend about one-quarter of our electricity budget on lighting, or more than $37 billion annually.

Light is important. Whether from sunlight or the light produced inside your home, humans need it to survive. A room can be transformed just by a flick of the switch. It seems logical, then, that one would turn to the most energy efficient and long-lasting light sources.

Do you need to change a few light bulbs in your house? Perhaps you are exploring lighting options for a remodeling project? A great option to investigate when you next go shopping are LED (Light Emitting Diodes) light bulbs. LED boasts an extremely low power consumption, which can save you on your next energy bill. These lights are very durable and they have an impressive life span (50,000-100,000 hours, compared to incandescent light bulbs that last around 1000 hours). The best part is that LEDs are recyclable and contain no mercury or other toxins, which helps the earth out.1
