At Energy-Minded U.S. Hotels, They’ll Turn the Lights Off for You
The Palazzo’s use of the key card device is not unusual in Europe or in other parts of the world, like Asia. Even in countries like Norway where electricity is relatively inexpensive, many hotels use them to reduce energy costs.
American hotels have long resisted key cards or other energy-saving systems. Energy was cheap, and hoteliers feared that guests, who routinely left their rooms with the lights and air-conditioner on, would see any check on their energy use as an inconvenience.
But the aversion of hoteliers in the United States is slowly shifting as Americans have become more energy conscious and more states and municipalities have adopted rigorous building codes for energy use.
