I do some green things and then some things that piss green people off...
as far as green...
All of my appliances are new and energy efficient
use those new green light bulbs throughout the house
bought my fiancee a clean diesel
recycle cans, plastic, and paper
Have a compost pile
Drive a motorcycle to school/work whenever the weather permits that gets great mileage and has great emissions
as far as pissing off green people
Keep my apartment and house at 68 all of the time even when I'm not going to be at one of them for a while
Drive a land rover with about 1000 pounds added to it (bigger tires, brush guard, winch, roof rack, etc) that gets about 17 miles per gallon
Have a 35 zr donzi that burns the hell out of gas

(It is technically my dad's but I take it out several times a week to relax)
Leave a lot of lights on
drink bottled water
Eat meat at every meal
Water my grass 3-4 times/week
