Cree, Inc., manufacturer of the popular LR6 LED downlight, just announced a new light bulb. The company unveiled “the brightest, most-efficient, LED-based A-lamp that can meet Energy Star performance requirements for a 60-watt standard LED replacement bulb.“ Cree attributes the bulb’s performance to TrueWhite technology and a patented remote-phosphor technology.
I’m going to be honest, I hate my CFLs. After blowing all sorts of cash on these things, I’ve yet to find one that performs the way I’d like it to. Plus, since lighting accounts for some 11% of residential energy use on average, it’s an area that deserves attention. In doing so, I’ve been playing with various options and think LEDs may just be the ticket.
Keep an eye out for the next acronym in energy-efficient lighting: ESL, or Electron Stimulated Luminescence. ESLs use “accelerated electrons to stimulate phosphor to create light, making the surface of the bulb ‘glow,’” according to Vu1 Corporation, a maker of ESLs. The technology is being touted for producing light that’s similar to an incandescent bulb but about 70% more energy-efficient.
GE unveiled a panoply of home technology at CES this week. The company’s taking an aggressive approach with smart green products and may just capture the heart of Americans everywhere. If GE’s vision comes true, here’s some of what will connect the home of the future:

I would like to be able to state that I became an architect to save the planet from wasteful, polluting buildings – the built world accounts for some 40 percent of the greenhouse gases we produce – but the truth is my fondest desire was to become a thespian. As the theater is an iffy business and my best stage feature, a lively head of hair, was rapidly waning, I turned to a more sensible alternative: architecture school.
