Change All Your Light bulbs to Energy Efficient CFLs
CFLs use almost half the energy as typical light bulbs. That adds up to be a lot of power. CFLs also last much longer than other light bulbs. This switch can easily save a small house $100 dollars a year or more.
Bike or Walk
Gas is over 4 dollars a gallon now and biking or walking someplace can save you loads of cash.
