"Top Chef" stars Fabio Viviani, Stefan Richter and Antonia Lofaso whip up a variety of green tips. (Gerri Miller)


Stefan Richter: My name is Stefan.

Antonia Lofaso: This is Antonia.

Fabio Viviani: I'm Fabio and you're watching the Mother Nature Network.

Stefan Richter: My name is Stefan from Stefansrestaurants.com and I do have a green tip. I changed all my light bulbs to energy-saving light bulbs. My electricity bill went from 6,000 to 2,000, so makes 4,000 that I can by a Maserati, and a Ferrari a month. So, you save on one side you spend on the other.

Antonia Lofaso: My name is Antonia Lofaso from "Top Chef All-Stars" and my green tip for you would be to definitely take advantage of your local farmers markets — they're delicious and seasonal and they're always fresh.

Fabio Viviani: My name is Fabio Viviani, my green tip is shut the lights off if you don't need it and close the water. We need more of that.
