Though it still remains somewhat of a taboo to discuss, the skin-color barrier has historically been just as daunting for people of color as the racial barrier. A 2004 study showing that light-skinned immigrants in the U.S. earn more money on average than darker-skinned immigrants confirmed what many African Americans have privately known for years: that there are benefits simply for being a minority who is fairer. Traditionally, "beauty barriers" have almost exclusively been broken by lighter-skinned blacks - from the earliest black sex symbols such as Lena Horne and Dorothy Dandridge to the first black Miss...
...familiar with the annoyances that come with compact fluorescent lamps. Yeah, yeah, CFLs use about a third as much energy as old-school incandescent bulbs, last many times as long and can save consumers an average of $50 over the life of a bulb. But the light that standard CFLs give off doesn't seem inviting, they can't be used with a dimmer, and they take way too long to turn...
Take heart, however, because a new generation of CFLs aims to address these concerns. And other lighting innovations are hitting the market just as President Obama ups the efficiency stakes. This summer he announced tougher standards that, in combination with a law passed in 2007, will ultimately make it a lot less expensive for Americans to light their homes and offices...
...Electric lighting currently accounts for 19% of the world's electricity use, pumping as much greenhouse-gas pollution into the atmosphere every year as half the world's cars. Much of that results from outdated, inefficient light sources in homes, offices and parking lots. Energy-efficiency advocates say that because lighting is ubiquitous, the new guidelines will have a bigger environmental impact than any other appliance standards, including those for refrigerators and air conditioners...
...CFLs and incandescents could both be left in the dark by LEDs, or light-emitting diodes. The leading lighting companies are racing to release traditional-bulb-shaped LEDs that last five to 10 times as long as CFLs, contain no mercury and use far less energy. These amazing new lights also come with a flashing-neon price tag: $50 for Lemnis Lighting's Pharox, which uses 6 watts of power to match the output of a 60-watt incandescent...
