10. Get solar power
Having solar panels on your roof not only reduces your utility bill, but also puts you in the enviable position of having power when nature strikes down the energy grid. They'll eventually pay for themselves and they're also a great hedge against future spikes in energy costs. In the event of a disaster, you'll have power to fend off the zombies, nuclear mutants and ninja biker gangs that will inevitably rise up from the ashes of polite society.
