Given all the gloabl-warming concerns, persuading people to save energy for the greater good does not seem so effective.
A better approach may be to show people the externalities that they stand to gain.
For instance, taking public transportation not only reduce gasoline consumption, it
1. is great exercise (b/c you usually have to walk a few blocks)
2. is a great time to read
3. is relaxing
4. helps with directions (this is my secret on how I know the city so well)
Next weekend, two girlfriens will be staying with me, and I hope to show them the SF Bay Area that very few people know, the one without a car...
