Do you know what percentage of homes in America utilize energy-efficient bulbs? How is one of America’s largest cities keeping tabs on its energy use? For the answers to these questions and interesting lighting news, read on!

More U.S. Households Using LEDs and CFLs

According to recent data by E Source, the energy efficiency trend is gaining a lot of ground here in the U.S., as more and more households are using compact fluorescent lamps (CFL) or light emitting diodes (LED). E Source reports that 87% of households use at least one CFL or LED, while 77% use three or more. What factors decide who uses which type of bulbs and how many of these bulbs are used in households? E Source uncovered some interesting findings. For example: • The percentage of households using multiple LEDs or CFLs goes up as annual income increases. • Homeowners are more likely to use multiple LEDs and CFLs than renters. • Older adults are more likely to use multiple CFLs, while younger adults lean more towards LEDs Rachel Cooper, research manager at E Source, raises interesting speculation: “These findings lead us to wonder, ‘What would saturation levels look like if these energy-efficient bulbs-particularly LEDs-were more affordable?’”

Philips’ LED Bulb Could Replace Fluorescent Bulbs

LED technology is rapidly advancing, quickly changing the face of energy efficiency by offering longer life hours and considerably reduced electricity usage. LEDs first replaced CFLs, and now they’re replacing… fluorescent bulbs? That’s right. Philips has announced a prototype LED that could save the U.S. billions of dollars annually by replacing fluorescent bulbs. This new bulb only consumes 5 watts of energy, but produces a whopping 200 lumen per watt, far superior to the 100 lumen per watt fluorescents can produce. Philips estimates that with the new LED, the U.S. would save an astounding $12 billion a year while preventing the release of 60 million metric tons of carbon dioxide. Philips said it plans to deliver commercial and industrial versions of the bulb to the market by 2015, with consumer products quickly following.

UCLA Publishes Electricity Usage Map

The University of California, Los Angeles (UCLA) has created an innovative way for Los Angeles to monitor how it uses electricity, block by block, allowing the city’s planners and Department of Water and Power to develop more finely tuned programs aimed at high energy users or low-income neighborhoods to improve energy efficiency. The map uses census and land use information to show how income levels affect electricity use and the differences between electricity usage of single family, multi-family, and commercial buildings. The map can even give usage projections for high heat days.

Conroe ISD Receives $15,000 to Upgrade Lighting

Conroe Independent School District (CISD), located in Conroe, TX (near Houston) has been recognized by Entergy Texas, Inc. for participating in their SCORE program and rewarded CISD with a $15,000 check to upgrade the district’s lighting. The goal of the SCORE program is to provide energy performance benchmarking, technical assistance, and cash incentives to help schools save energy and money. The $15,000 prize will go a long way for the district’s lighting upgrade, with CISD saving more than $28,000 in annual energy costs, the equivalent of carbon dioxide emissions from the electricity use of 30 homes for a year
