Save Energy -- Switch to Compact Fluorescent Bulbs (CFLs)

If you haven't already, replace your household light bulbs with Compact Fluorescent versions. If every American home switched just one bulb, it would reduce greenhouse gas emissions the same as pulling 800,000 cars off the road.

As opposed to incandescent bulbs, CFL's last up to 10 times longer, use about 75-percent less energy, and will save you around $30 over its lifetime.

On the downside, they contain poisonous mercury and therefore need to be recycled instead of thrown in the garbage, which can be a hassle. If they break, it's trouble, but you can visit Energystar.gov for cleanup instructions.

Samsung's New Blue Earth Cell Phone Is Solar-Powered



Samsung's Blue Earth handset might just be taking the green thing to a whole new extreme. Made from PCM, a recycled plastic from water bottles, the phone boast an "eco" mode for efficiently adjusting screen brightness, backlight duration and Bluetooth usage, and an "eco walk" app / built-in pedometer to tell you how much CO2 emission you've saved by walking instead of driving. The best part? It's got a giant solar panel on the back that'll apparently charge it enough to make a phone call anytime the sun's peaking out.

Of the form factor, Sammy says it "symbolizes a flat and well rounded shiny pebble" -- which we hope means it can skip puddles with the best of 'em. It'll come in recycled packaging with an energy efficient charger. What we don't know, unfortunately, is what makes this phone tick, neither OS nor hardware specs. Not a word on price yet, but UK environmentalists can look forward to this one second half of this year.

Eco-Friendly Dubai Pyramid Concept Could House 1.1 Million


As we learned from 'Wall-E,' people with half a mind for themselves probably won't be kosher with living with 1.1 million or so other inhabitants within a pyramid. That being said, there's always the brainwash approach to getting 'em in there, and if hordes of people were ever filed into the conceptual Ziggurat, Mother Earth would surely appreciate it.

The 2.3-square kilometer building would be able to house over 1 million people and be "almost totally self-sufficient energy-wise." By tapping into the planet's renewable resources, designers assert that it could practically be carbon-neutral, and given that transport within the machine would be connected by an "integrated 360-degree network," fuel-burning cars would be pointless. As with most things in Dubai, this one seems larger than life, but if the Burj Al Arab is any indication, there's at least a minuscule chance this thing comes to fruition.
