Imagine a supercar that hits 60 mph in 3.2 seconds and has a top speed of 200 mph. Now imagine this car getting 94 miles per gallon. This is the Porsche 918 Spyder prototype, revealed at the Geneva Motor Show.

The 918 Spyder is propelled by a 500-horsepower V8 engine along with front and rear electric axle motors. Liquid-cooled lithium ion batteries can be charged by a standard household electrical socket.

HYmini has revealed its latest renewable energy charging solution at this year's Consumer Electronics Show. This foldable, fully portable contraption includes its own solar panel and wind turbine.

As long as the wind is blowing and the sun is shining the Biscuit will charge two AA batteries stashed inside the frame. The device also includes a USB port for charging other devices via USB cable.

What carries 5 adults, goes from 0-60 miles per hour in 5.6 seconds, and doesn't burn a drop of gasoline? Only the Tesla Model S.

With a 300 mile range and a $50,000+ price tag this vehicle is the company's most ambitious project yet. The specifications are incredible considering Tesla just launched its first vehicle, the Roadster, in 2008.

What a great product. Novothink's Surge for iPhone and iPod Touch is the first solar charger to be certified by Apple. This slip-on case has its own internal battery and LED status lights, and a mini-solar panel on the back of the unit.

Surge allows full access to the iPhone, with openings to the speakers, USB cable port, and camera. There's even a cord included to hang the iPhone from a backpack or your belt while outside to charge it up.

Just in time for Earth Day, AOL has released a "Green Toolbar and PC Utility." If you're like me the computer basically has a sort of 'diplomatic immunity' when it comes to energy consumption issues. However, this new utility from AOL looks like a great way to "greenify" your computer.

The utility, which is free to download, reduces your computer's energy consumption by adjusting both monitor and power settings. These adjustments can result in using up to 100 kilowatts less per year which, according to energystar.gov,

LED holiday lights are sweeping the nation. There's a good reason why they are showing up on Christmas trees and houses faster than you can say light-emitting diode. They pay for themselves.

A typical string of lights may cost around 30 percent more at the store, but take them home and plug them in. Your power bill for the LED lights will be up to 98 percent less. Not only will they immediately save electricity, LEDs are unbreakable and can last up to 20 years.

You can read as much as you want about driving methods that will result in better fuel efficiency, but putting them into practice is next to impossible without proper feedback. The ScanGauge II effectively solves that problem by giving the driver real-time data as well as post-trip data, letting the driver adjust his or her driving methods on the fly to maximize fuel efficiency.

The ScanGauge II is an energy monitoring device that will mount on the dashboard of most vehicles. As you can see in the picture (which must be in a car involved in a high speed chase), the ScanGauge II shows you your fuel economy (MPG), vehicle speed, engine speed (RPM) and battery voltage. It also shows

If it looks like a jet engine that's because it uses the same principles. However, this turbine is not expending energy, it's generating energy. Most wind turbines max out at 60 percent efficiency.

The problem is that 40 percent of the wind passes around the blades of the windmill without actually turning the generator and making power. Here comes the FloDesign Wind Turbine to change all of that. By focusing the wind over the blades, it improves efficiency dramatically.

The ecobee Smart Thermostat is a programmable thermostat that will help you not only reduce your footprint and conserve energy, but save money as well. Using it is simple.

The unit is equipped with a touch screen display that makes programming quick and easy. You can change the temperature simply by touching and dragging the temperature reading along a thermostat diagram. You can also program the ecobee to have different settings for each day of the week and even each hour of

Although it may save energy, most of the time a compact florescent lamp (CFL) doesn't win awards for aesthetics. They last for years, but breakage and disposal are usually problematic due to the presence of mercury and lead, both dangerous substances. Enter the Marexim Safety Bulb.

Not only do these bulbs look like regular light bulbs, they are enclosed to prevent breakage. Not only are they enclosed to prevent breakage, they stay cool to the touch when on, the glass and solder inside is lead-free, and the bulb contains no liquid mercury. An RoHS compliant, energy efficient CFL for the masses? Wait, this gets even better.
