US, China Partner on Efficiency – Can It Make a Difference?

Former President Bill Clinton’s Global Initiative has been all over the news lately, working with nongovernmental organizations (NGOs) and big business to move the ball forward with clean energy solutions to global warming. Whatever you think of the guy, it’s hard to deny that his partnerships are impressive and the results could be revolutionary.

Besides the agreement by utilities to invest in energy efficiency, and besides Florida Power & Light’s major new commitment to solar energy, the Clinton Global Initiative is also partnering with the Joint U.S.-China Cooperation on Clean Energy (JUUCCCE) on efficiency efforts in China.

The China Lighting Conversion program will distribute 10 million free energy-efficient compact fluorescent light bulbs (CFLs) to customers. CFLs use one-third the energy of traditional bulbs, but are still cost-prohibitive to many Chinese. According to JUUCCCE, the CFLs would save about 3.7 million tons of CO2 over 4 ½ years — enough to avoid having to build one typical U.S.-size coal plant. While I tell myself it’s encouraging to see the start of another clean energy commitment in China, I’m still disheartened by the multiple coal plants they’re building each week. But change has to start somewhere.

The other JUUCCCE program is the Energy Efficient Urban Design Tools for Mayors. This is an interactive, multimedia curriculum to train hundreds of Chinese mayors on technology and best practices that can make their cities more energy efficient. Mayors will learn about green building programs, for example, and will connect with vendors, service providers and financial advisors to help them implement what they learn. The key with this program will be rigorous follow-up and support to ensure that the information learned isn’t forgotten or lost in the bureaucracy one the mayor returns to the city.

The first phase will begin with the CFL program in April 2008, with the training for mayors to start in October of next year.

Popular Mechanics Puts Efficient Light Bulbs to the Test

Popular Mechanics just tested seven common energy-efficient, compact fluorescent light bulbs (CFLs) for brightness, color, and power use. Can they compete with the traditional incandescent light bulbs that most of us use?

They sure can. Although the old-fashioned incandescent bulb measured slightly brighter than the equivalent CFLs, the test subjects in the Popular Mechanics study couldn’t see any significant difference. In fact, when it came to the overall quality of light, every single CFL scored higher than the incandescent: “In other words, the new fluorescent bulbs aren’t just better for both your wallet and the environment, they produce better light.”

To track the results, PM used a Konica Minolta CL-200 chroma meter to measure color temperature and brightness, and a Watts Up? Pro ammeter to track power consumption. They performed a double-blind test with three Popular Mechanics staffers and a lighting expert from Parsons The New School for Design in Manhattan. They put the participants in a color-neutral room, turned on the light, and asked them to examine colorful objects, faces and reading material, then rate the bulb’s performance.

The N:Vision Soft White bulb got the highest score of an “A.” The study found it to be “one of the top bulbs for reading and illuminating faces, the best-in-test N:Vision was noticeably ‘slow to warm.’ Still, it was ‘nice, pleasing and good overall.” The N:Vision has an average cost of $5.97 each.

CORRECTION: I had previously noted that the Sylvania Double Life Soft White was the lowest rated CFL. This is incorrect: The bulb is not a CFL but the incandescent against which the other CFLS were measured. It received the lowest score of all bulbs.

The lowest rated CFLs were the GE Soft White (which produced “accurate” color but made details hard to distinguish) and the Westinghouse Soft White (which was an average scorer overall but hurt one person’s eyes while reading). Both bulbs earned a B+.

I regret the error.
