Similar fees have now spread to at least 16 states and the District of Columbia, where electricity and natural gas prices have risen.
Hotels use energy mainly for lights, heating and air conditioning.
States where the surcharges are now showing up include Illinois, Kentucky, Louisiana, Minnesota, Missouri, Nevada, New Jersey, New York, Ohio, Oklahoma, Oregon, Pennsylvania, Texas, Virginia, Washington and Wisconsin. Many hotels say they will lift the surcharges when energy costs return to normal. Some Hilton hotels in 12 states and Washington, D.C., added the fees in April. Hilton chains include Hilton, Embassy Suites, Doubletree and Hampton Inn. Hotels also are trying to drive down energy bills by reducing consumption.
