5-1 UNDERSTANDING ENERGY USE
U.S. restaurants spend more than $5 billion per year on energy; in 2006, an estimated median expenditure of $161 per seat. Energy use per square foot in a foodservice facility is greater than in any other type of commercial building—more than triple what a hospital uses per square foot and at least six times what an office building uses per square foot (see Illustration 5-1). Illustration 5-2 gives you the basic guidelines for how energy is used in a restaurant.
On your profit-and-loss statement, utility costs will be only 4 to 7 percent of your total operating expenses. However, National Restaurant Association studies suggest they are expenses that can be cut by as much as 20 percent with smarter energy consumption; utility companies claim you can realize savings as high as 30 percent. These potential savings, of course, have a major and direct impact on your bottom-line profit. Table 5-1 charts the potential savings, which vary (of course) with your electric costs and amount of savings. And remember, because its energy use is so high, this type of business is especially vulnerable to fluctuations in energy costs.
