We both have electric bikes but I am sorry to say we don't use them as much as we should. Commuting on an electric bike does stop you getting sweaty and you can arrive less disheveled than on a regular bike.
I am a fair weather bike commuter. Even though it is sometimes quicker getting to work on my bike and definitely quicker getting home, I am outside all day at work I don't want to get wet and cold before I start!
Phillip can walk to work so we have one small car.
Topics to research:
Car clubs, car sharing/pools
Energy efficient driving
