1. Replace single-use batteries in your camera with rechargeables

Over the holidays, you may have noticed that your camera eats up battery life faster than Takeru Kobayashi chows down 10 hot dogs. You can save a lot of energy (and money) by making the switch to rechargeable batteries. Sure, the upfront cost will be higher, but it will pay for itself in just three photo-worthy events. 

2. Make the switch to CFLs or LEDs already

While the actual details of the "light bulb ban" are still up in the air, there's no question that switching out your incandescent light bulb for a CFL (compact fluorescent lamp) or the even more efficient LED (light-emitting diode) will save energy and a ton of money for you in the long run. Incandescents turn just 2-10 percent of the energy they use into useful light, releasing the rest as waste heat. However, a CFL will save about $30 over its lifetime; pays for itself in about 6 months and lasts about 10 times longer than an incandescent. Seventy-four percent of Americans have already made the switch, so go ahead and jump on the bandwagon.
