LED Lighting
Light-emitting diode bulbs that use 75% less energy and last 25 times longer than incandescent bulbs. A full home LED conversion saves $100-200/year in electricity.
Why It Matters
LED conversion is the fastest-payback energy upgrade. If you still have any incandescent or CFL bulbs, replacing them provides an immediate return.
