A bit, but not very, and not by choice.

I try to not waste more hot water than I have to, cause it makes my electricity bills larger. I use a bicycle to get most places because cars are a bit too expensive for me.

I don't care about energy saving light bulbs because honestly, it's so cold in Norway that the heat from regular light bulbs doesn't go to waste 80% of the year. Same deal with my TV and other electrical devices.

I recycle soda/beer bottles/cans because we sort of get money for doing so but not really.
