Improving the efficiency of lighting leads directly to increased profits and reduced environmental impact. The Department of Energy notes that widespread changes in lighting, especially the adoption of LEDs, has the greatest potential impact for energy savings in the next decade in the United States. LEDs are an illustrative example for the business case for upgrading lighting. The price of LED bulbs (right graph) has been plummeting even as their efficiency continues to increase (left graph). LEDs, which last 25 times as long as traditional incandescent bulbs (as long as 25 years) and use 70%-80% less energy, are now comparable in price to other bulbs.
