According to the Environmental Protection Agency, energy costs reach $2,196 per room each year in the 47,000 hotels and motels in the United States. That equals about 6 percent of all operating costs for a hotel. When staying at a hotel, follow the same mindful habits you do at home: Turn off the thermostat or lower or raise it to save energy when you leave the room. If you notice a leak in the bathroom, report it to the front desk. If you use the hotel gym, turn off the TV when you’re done to cut energy costs. The more we do to lower energy usage, the lower hotel rates will become -- it's a win-win for everyone.
