An affordable and easy way to increase efficiency and reduce carbon emissions is to install light emitting diode (LED) and compact fluorescent lamp (CFL) light bulbs as a replacement for your incandescent lighting. In fact, to steadily increase the efficiency of world energy use, this is the first step in the Earth Policy Institute’s climate […]

I was recently offered a Philips SlimStyle LED for review. $0 is a pretty good price for an LED, so I took it. I have to admit that this is the first LED I’m using as a “normal light bulb.” All the others we have are CFLs. After about one week…
It all started with candles. The tradition of an illuminated holiday tree emerged around the 18th century, when wax candles were used to festoon the branches of fresh evergreens. Candles. The notion is somewhat terrifying today. But even those incandescent bulbs of childhood had their safety and practical drawbacks. The large glass bulbs would shatter; […]
Little acts do add up over time, and they’re much easier to turn into habits than big changes. ENERGY STAR is celebrating the power of small acts with its “Do 1 Thing ENERGY STAR” campaign. This week’s theme: lighting.
LEDs (Light Emitting Diodes) are now poised to take the small business and residential lighting market by storm with their drastically-reduced up-front costs. Here are a few more facts you may want to consider when deciding whether the time is right for you to give LEDs the green light.
Lighting is a critical aspect of development for the world’s poorest regions. Two social enterprises have taken to crowdfunding platforms to raise money for bringing their innovative lighting technology to the market.
Technologies like solar-powered LED lights may seem like cool gadgets to those of us in the “first world”… but they’re necessary tools for combating poverty and poor health in the developing world.
What are the real differences between incandescents, CFLs, and LEDs? Are the latter two really cheaper in the long run? A new infographic spells out the differences.
A few months ago, I took a look at the difference micro solar systems were making for people in the developing world: a small system that provides enough energy to charge a light and a cell phone can change these people’s standard of living immensely. As you might imagine, companies like Barefoot Power aren’t the […]
Change you light bulbs to CFLs… how many times have you heard that one? To be honest, I’m a little bored with it… I mean, doesn’t everyone already know that? My boredom’s probably a good sign, though… if those of us who follow these issues daily find tactics like changing bulbs “old hat,” then they’re […]
By Lester R. Brown The lighting sector is on the edge of a spectacular revolution, a shift from the century-old, inefficient incandescent light bulb to far more efficient technologies. Perhaps the quickest, most profitable way to reduce electricity use worldwide—thus cutting carbon emissions—is simply to change light bulbs. The Current Standard in Energy-Saving Light Bulbs: […]
Think back to the last direct-marketed product you saw on television. You probably remember the hyped-up pitch person, the “special offer” for buying now, the price that ends .95. You may also remember thinking “Why would anyone want that?” Yes… most of the products marketed on television border on useless crap. They’re symbols of conspicuous […]
