Lighting likely accounts for 12% of your home’s energy use – but don’t worry. Improving lighting is a fast, simple way to reduce energy bills. And with new lighting standards, you have more money-saving options than ever before.
New Lighting Standards
Since new lighting standards began in January 2012, light bulbs are almost 30% more efficient than the old-style incandescent bulbs. That means families who change at least 15 of their bulbs could save between $50 and more than $100 per year in electricity costs.

Looking for an energy-efficient alternative to Christmas lights? Consider a string of light-emitting diodes, or LEDs, which produce light using the movement of electricity along the path of its semiconductor. As the electrons stream across the semiconductor, they create electromagnetic radiation, some of which takes the form of visible light.
