Light. Saving Money On Home Lighting Flashcards
The Energy Independence Act of 2007 mandates that 100-watt incandescent lights be phased out by:
January 2012 and the plug pulled on all remaining incandescent bulbs by 2014
CFLs are those expensive twisted bulbs some of us now use. Yes, they are more expensive than traditional bulbs, but CFLs are long-lasting and usually pay for themselves in less than:
nine months. An ENERGY STAR-CFL uses a quarter of the electricity of a traditional bulb, saving you 75 percent.
When it comes to saving energy, LEDs are the gold standard of home lighting. Instead of using a gas to emit light – as CFLs and incandescent bulbs do – LEDs light up when:
electrons move around a semiconductor. It’s the same technology as the lights on a cell phone, microwave and cable box. LEDs last 25 percent longer than Thomas Edison’s invention, and generate between 75 and 80 percent in savings.
A burning light bulb uses a certain amount of electricity, which is measured in:
watts. By lowering the wattage with a special switch, consumers can manage the bulb’s electrical consumption. Dimmers come with a dial or a slide bar, which allows homeowners to adjust the wattage and thus the amount of illumination.
_____of the energy used by an incandescent bulb is wasted, while only ______ percent is converted into light. The new light bulbs save energy by turning more electricity into light.
