One of the easiest ways to get a grip on your energy use is to install compact fluorescent light (CFL) bulbs in every fixture in your house where they will work. One big exception is lights operated by dimmers. CFLs use about a fourth less power than incandescent bulbs - a 13 watt CFL puts out the same about of light as a 60 watt regular bulb. Add up the difference over time and you're looking at serious savings.
Yes, CFLs cost more initially, but you can even beat that by buying yours at one of many local stores offering rebates from NV Energy. I just bought a subsidized pack of four 13 watters at Scolari's for $2.99. Over the long haul, you'll also be buying fewer bulbs - CFLs last thousands of hours longer than those old fashioned models.
Nothing is perfect, including CFLs. They contain a tiny amount of toxic mercury, meaning proper disposal is not just tossing them in the trash. Keep your dead ones and take them to any of numerous places around town that accept them for recycling. It's important to recycle CFLs and keep that mercury out of the landfill.

Beyond the very real lifetime issues when used in sealed/closed fixtures, the lousy power factor of CFLs means the power company has to produce twice the energy the thing actually uses to compensate. By the time you figure in the energy needed to produce the circuit boards and components not to mention the post consumer handling requirements. I would hardly call them “green” and might even belive they result in greater total energy consumption than incandescent bulbs.
