It's a good day to get what you want, so try using your persuasive powers to convince friends to change their incandescent light bulbs with leds and cfls that use less energy and last hours longer. Remind your pals that not only are they helping to save the environment, but in the long run they'll be cutting their electricity bills in half. Don't forget to safely recycle cfls when they finally go kaput, since they contain small amounts of mercury.
