A few years ago, I decided to figure out my exact personal carbon footprint—from every glass of wine, to a new pair of underwear, what impact I was having on the world. I thought I was probably doing a decent job; I was already running a renewable energy company, commuting by bike, and aware of energy issues. But the picture was pretty grim.
People have called me anally-retentive and obsessive-compulsive, and that's true. This is my life in excruciating detail, converted to the basic unit of watts so everything could easily be compared.
