Energy...

If you own a Garmin GPS unit, and you're looking to make your driving just a little bit greener, then the company has something just for you.

Their new ecoRoute program -- announced recently at the Consumer Electronics Show -- helps you to calculate the most eco-friendly driving routes available to you. ecoRoute users have the option of choosing the route that will use “less fuel” compared to other routes. Garmin says the program "will determine if more fuel efficient routes exist based upon road speed data and vehicle acceleration data for a given route."

ecoRoute also keeps track of your mileage and your fuel economy over time, both of which are great data points to have to help you improve your driving.

ecoRoute is available online as a free download. It's compatible with Garmin's nüvi 205 and 705-series products.
