I paid $3.06/gallon for gas yesterday (in Connecticut), and $2.95/gallon this morning (in Virginia).
"Gas is going to hit $5.00 a gallon," my brother Ed said. "Yep," I said.
According to the Carbon Calculator, my activities produced approximately 26,000 pounds in greenhouse gases last year -- less than the national average of 35,000 pounds/household, but still a lot for one person. But I can buy 20 green tags, at $20 each, and fund enough renewable energy so that I have a zero net impact on the environment... or at least, that's the theory.
It's a theory I like, since I don't plan to stop traveling any time soon, and I wouldn't function very well without electricity.
Dizzy and I are in Mechanicsville this afternoon, and it's thunderstorming. If Mom were here, she'd say, "Get that computer off your lap, do you want to be electrocuted?" I don't, so I'd better log off now.
