I love Planet Green! It's one of my favorite channels. G Word is a really good show with lots of cool & practical info (it's an hour-long daily(ish) hosted show). Greenovate is like Flip That House only with green building materials & practices, and Wasted! is great for shedding light on just how big of an impact one family's wasteful ways can be on the planet, and showing useful ways that family can make a difference in their energy bills.
We only recently got the channel added to our lineup.
I was already really into the recycling thing, and now I know even more ways to recycle and cut energy bills & use. What can I say... I'm a compost-making, rain water-saving, CFL-using, bag-bringing, organic-gardening, reuse-preaching, freecycling, recycling nut who drives a Range Rover. But I really use it, and I drive so few miles a year I don't feel too bad.
Very cool that one of our own will be on. I've got it DVR'd & look forward to seeing it!
