Copenhagen Light Festival considers energy

The festival will actively contribute to reducing electricity expenditure, through limited LED-usage, and by getting visitors to gather outside and leave TV’s and computers turned off at home.

From the outset Copenhagen Light Festival has concerned itself with limiting energy expenditure. In 2023, the festival will gather the light installations geographically, so that the festival remains as beautiful as always but with less energy used.

Facts:

  • During one whole day the festival’s electricity usage will correspond to the total usage of 3 fully charged electric cars (Tesla 75 kWh X 3 = 225 kWh).
  • Over the entire 3 weeks of the festival, the amount of electricity used will correspond to 3/4 the amount used at a single professional game of football at AGF stadium in Aarhus (over 7.000 kWh).
  • On average a light installation uses 1 kW. The festival will consist of a total of 45 installations, which are turned on in the time period 17-22 every evening of the festival’s duration. This equals 225 kWh used per day, or 4.725 kWh used during the whole 3-week period.

Society and the individual household save more energy by gathering than by sitting at home

Last year visited app. 350,000 Copenhagen Light Festival:

  • 350,000 each represents el-consumption in the festival, like a light bulb of only 13 Watts.

  • If we assume they turn off their TV and come to the festival, savings are per TV 75 Watt and a total of 21,700 kWh. – per hour

  • It also corresponds to approx. 27,125 computers streaming Netflix – per hour.

The festival uses LED technology exclusively.

Looking at the numbers, we can conclude that Copenhagen Light Festival actively contributes to lowering electricity expenditure.
During the COVID-19 lockdowns it was important to disperse – now it is important to gather around the common use of electricity.

The argument that lighting should contribute significantly to our society’s total electricity expenditure is the result of pre-LED logic – electricity bills since the introduction of LED-lighting have fallen by 60-90%.

Taking all of this into account, we are actively attempting to gather people around the festival in february of 2023. At the same time, we are constantly keeping an eye on the supply situation, and are ready to react to changes at any given moment. Copenhagen Light Festival is a vital part of the city’s economic and cultural life, and it creates a sense of community and proximity.

The low consumption surprises many, but it is important to focus on. Because by canceling events for fear of the electricity bill and without looking at the actual costs, we risk taking the livelihood from the small and medium-sized companies that are suppliers for various events and events.
