Every year, starting with Halloween and ending when the last Christmas candy is finally consumed, we descend into an excessive, unhealthy, guilt-ridden soiree of chocolate-eating hedonism. Ah, yes. The holiday season has arrived!

But instead of beating yourself up over every delicious little morsel, this year you can pat yourself on the back each time you eat a Hershey's Kiss -- because now, thanks to new technology, your chocolate habit is good for the environment!

An English company called Ecotech has figured out how to take waste from the chocolate manufacturing process (that used to end up in landfills), and turn it into bio-ethanol. Mix that with a little vegetable oil, and voila! You have biodiesel fuel that can power your vehicle.

The only downside is that the exhaust from this new form of biofuel doesn't smell like chocolate (which would've made it the invention of the century). Regardless, I think this totally gives you free license to have that second piece of fudge.

Go on, you deserve it. Your planet deserves it.
