Denmark's pragmatic shades of green (photos)
Denmark's implementation of green energy policy shows up in incremental changes big and small that have been made over decades.
Requiring a room key be put in a special outlet slot for a hotel room's electricity to work is typical of many European hotels. It prevent guests from leaving on lights and wasting energy. But one Denmark hotel took things a step further. In addition to the key card requirement, the room thermostat was set at 21 degrees Celsius (69.8 degrees Farenheit) and only offered a temperature change of plus or minus 5 degrees Celsius.

In 2009, DFDS Canal Tours began offering electric boat tours of Copenhagen's canals as an alternative to its diesel boats. The first electric boat in its fleet was named the Den Grimme Ælling (The Ugly Duckling), a nod to the famous Danish poet and fairytale author Hans Christian Andersen.
The boat holds 170 passengers and has four large lithium ion batteries with enough power to operate all day. It recharges at night when not in service. In addition to reducing the cost and pollution of diesel fuel, the electric boats also provide a nice quiet ride.
