Lighting Science Corporation has just announced a new breakthrough in high efficiency LED (light emitting diode) technology that outperforms existing LED streetlights, providing an even greater incentive for the nation’s roadways and institutions to make the switch from standard streetlights to more sustainable LED lighting.

The new LEDs, dubbed the PROLIFIC Series Roadway Luminaires, offer substantial savings over conventional HID (high intensity discharge) streetlighting.  Lighting Science also claims that PROLIFIC performs up to nearly 90 lumens per watt, giving it a big advantage over current LED technology, which performs at up to 60 lumens per watt.  To sweeten the payback even more, federal stimulus funds are available for cities to make the switch from conventional lighting to LED.

With the economy on the downturn, more and more people are starting gardens to help ease grocery bills. Growing one’s own food is a step towards living sustainably, so this is great news. However, more gardens mean more water use,  and 40% of water used during the summer is used outdoors. So, as you plan your garden this spring, be sure to keep water in mind and take measures to reduce water usage.

Reducing water usage in an organic garden not only conserves our most precious resource, it also lowers costs and in many cases, benefits the plants as well. By paying attention to how your garden is watered, you can be sure to give plants just the amount of water they need to thrive without overdoing it. Many of the water saving methods mentioned below also benefit the soil and enrich your garden in other ways. Water should be a key part of your garden planning from day one. Read on for ways to garden sustainably and save water.

Struggling Indian car company Tata Motors has announced the commercial launch of the Tata Nano, the most fuel-efficient petrol-driven car in India, and quite possibly the world.

The Tata Nano, keenly anticipated across India since its unveiling early last year, is capable of an incredible 23.6km/litre (55.5 mpg) and ultra-low carbon emissions of 101 g/km, one of the lowest in India. Oh, and with prices starting at about 100,000 rupees ($2,050), it’s also the cheapest car in the world (more pics after the jump).

Last week, Famous DC was the first to report on New York’s recently elected congressman Eric Massa’s poorly-conceived environmental publicity stunt.  Massa’s plan was to drive from his congressional district in New York to Washington DC in a hydrogen fuel-cell powered car.  In other words:  an efficient, leisurely, and environmentally responsible drive across 300 miles of the American Northeast.

“What,” you may be asking, ”could possibly go wrong?”

Plenty.

More on why we should never, Never, NEVER elect public officials who are bad at math after the jump.

PC energy saving specialists Verdiem have today released free downloadable software designed to help users slash their energy use up to a massive 80 percent.

According to Allison Cornia, vice president of product management at Verdiem, “If we could get just 10 per cent of the world’s one billion PCs using [the product] properly we could save 32 billion kilograms of CO2 a year. That’s equivalent to taking half a million cars off the road.”

Scientists at the University of New South Wales have set a new world record by creating the first silicon solar cell to achieve 25% efficiency.

Team leader, Prof. Martin Green of the university’s ARC Photovoltaic Centre of Excellence, says their world-beating solar cell is now a massive six percent more efficient than the next best technology. The record edges the current generation of solar cell technology closer to the theoretical limit of 29% efficiency.

As far as green gadgets go, this little desktop computer will give Dell and (to a lesser extent) Apple a run for their money.

The CherryPal promises to be affordable, efficient, and powerful enough for the average PC user. At first glance, that stats on the system look modest, and for good reason. This design actually cuts out 20% of PC components to reduce energy usage. But fear not, despite being small (the size of a paperback), the CherryPal claims it can start up in 20 seconds, and cloud computing provides more power/storage when you need it. A Linux operating system (now more user friendly than ever), and cloud computing means you won’t need to worry about viruses or install protective programs that can slow down your PC.

I cover a lot of upcoming or future technology, but it’s time to step into the present and aim for the past. Today we’re going to look at a technology available right now that can make some wanton energy waste history. It’s a surge protector that stakes the hearts of vampire electronics without hassling you, the sleeping victim.

Vampire appliances are pretty much anything you can plug in that still sucks energy when it’s supposedly turned off. Some are pretty obvious - the clocks on your microwave or VCR/DVD player burn all day, everyday. We know they’re not “off” because we cans see their LEDs glow. But other electronics, from your television to your cell phone charger also draw power when they’re plugged in but not in use. Check out a handy graph from Good Magazine. Some gadgets are notorious, like your plasma TV. Estimates claim that 5% or more of U.S. energy usage is insidiously wasted by “stand-by mode” or certain misleading “off” buttons. A whopping 5% may not sound like much, but it adds up to about $1 Billion dollars per year - and energy prices will probably continue to rise.

Be honest - how many times would you go around the house unplugging everything before it got old? Smart greenies have been switching off their surge protectors, but it’s easy to forget while watching your favorite late-night TV show or blogging at 4am. So what can we do about these metal-toothed Nosferatu in our midst? How about a surge protector that turns off all your appliances for you?

Imagine growing up, going to school, graduating, going to college for a couple years and then getting that magical phone call: "Son, it's time to change the light bulb." You rush home in flurry of excitement and anticipation as your parents show you how to change a light — something you yourself may not do until your own kids are in college. Those times are coming.

Well actually, they're here. But until prices coming

Until I wrote a story about China growing Jatropha in mass quantities earlier this year, I'd never heard of the plant. Now, it seems that wherever I turn someone's got Jatropha ambitions. It's gotten so bad that I feel compelled to ditch tomatoes, scrap the pumpkins, and grow some nuts. (No editor comments allowed)

What's Jatropha you ask? Up until recently, it's simply been a plant that's useful for live fencing and evil intentions:

If you're like me, there are often times when you plug your cell phone into your charger, fill up, unplug, and then walk away leaving the charger in the wall. This act can waste energy as a phantom pull is still exerted by the charger in your wall. Well, now there's a product that replaces all of your various chargers and makes the entire process much more efficient.

Called the Wild Charge, the
