Wiki-collaboration

I have been following the brouhaha about global warming, and I decided to pitch in my bit. It is towards this goal, that I started collecting tips on been carbon neutral. Every once in awhile, I come across a tip to save energy, water, or some other resource. Wouldn't it be nice if we could keep track of all these tips and share them with other people?

Turns out that there are many wikihows on how to save energy in various ways. For instance, check out http://www.wikihow.com/Increase-Fuel-Mileage-on-a-Car. there are many such wikihows with a lot of useful information. Being a true believer in wikis, I edited a few of these and added a few tips myself.
