Compact fluorescent lamps, or CFLs, use one fourth as much energy, last ten times longer than incandescent lamps, and are available in a number of sizes and shapes.
One of the best ways to reduce lighting costs and lighting energy use is to turn off lights when you are not using them.
Light-emitting diodes (LEDs) are small light sources that become illuminated by the movement of electrons through a semiconductor material.
Artificial lighting is responsible for almost 15% of home electricity consumption.
Incandescent lighting is the most common type of lighting found in homes and is also the least efficient light bulb.
Because of the intense light they produce, HID lamps are commonly used outdoors or in large indoor areas.
Halogen lamps, or tungsten halogen lamps, are a type of incandescent lighting.
While buying an Energy Star light bulb is the first step in energy efficient lighting, if your light fixture is wasting energy, your new light bulb is not going to make a very big difference.
Daylighting is the strategic and energy efficient use of windows and skylights to bring sunlight into your home.
