Audit yourself: A home energy audit is a way to inventory your home's energy use, where energy is lost, and where it can be saved. You can do an energy audit yourself or get a pro. Many utilities also offer home and business energy audits for free.
Reduce your use: The lowest hanging fruit just begging to be picked are simple energy-saving practices. They're also the most cost effective. Top tasks include:
Replace your light bulbs with compact fluorescent light bulbs (CFLs) or even cutting-edge light emitting diodes (LEDs).
b. Turn off lights and other devises when they're not needed. Check out the How to Go Green: Lighting guide for more lighting tips.
Eliminating electronics that sleep on a standby setting; they continue to pull a current even when "turned off."
"Wall warts," those clunky AC adaptors on many power cables, pull current, too, so those should be taken out of the wall when not in use -- this is also known as phantom power. Your best bet is a "smart" power strip, or a power strip that can be turned off at night.
Clothes driers gobble up a lot of power, so line drying can be a great energy saver!!
