The Copenhagen Crowne Plaza hotel located in the suburbs of the city has placed stationary bikes on its hallways where guests can paddle to produce green energy and win a voucher at the hotel restaurant.

When the guests paddle on these stationary bikes it generates electricity which is stocked in a battery before being injected into the hotel's power supply. If the guests produce 10 watt-hours of electricity which usually takes about
12 minute of paddling they are awarded Euro 27 voucher of the restaurant at the hotel.

The hotel has offerd free meals to more than 200 guests in the experiment that began in April and will go on for a year, according to the communication director of the hotel, Mr. Frederikke Toemmergaard.

The hotel claims it is a 100 percent green hotel and was established in November last November just before the UN Climate summit which was hosted in Copenhagen. The hotel is situated close to the Oeresund strait that separates Denmark from Sweden. It has about 1,500 solar panels that produce 170,000 kilowatt-hours of electricity.

At the basement of the 86-meter tall concrete and steel tower there is a geothermal well that offers eco friendly heating and air conditioning for the hotel and erducing its electricity costs by as much as 90 per cent.

The hotel also employs other Eco-friendly technologies like, low energy lighting, taps with water saver and use of biodegradable objects.

Copenhagen, the city that has more bicycles than cars is aiming to become emission free within 15 years. The projects such as this will certainly will help it achieve this goal and also set as an example for others to follow suit.
