Automative lights

You can see it from a mile away: the street where one automobile dealership after another is brilliantly illuminated, each seemingly trying to outshine the other. Unfortunately, much of this light is spilling off the lots, as well as being wasted upward into the night sky. While these lights serve a dual purpose of attracting potential customers and as a 24/7 security system, they devour energy! There are over 17,000 automotive dealerships in North America and on average, they collectively use up to 18% more energy annually than a typical commercial building. Out of the $1.9 billion spent on energy every year, up to 45% of that money is represented by lighting costs. This means thousands of dollars in energy costs for the typical dealership each year.
