Monitors (only in Danish)

Lifetime of a monitor – what does it cost?
When you buy a monitor, the cost of running it is reflected in your electricity bill over the period in which you own and use the computer. We call this the monitor’s lifetime costs, i.e. the total cost of using it. We have set the lifetime to 6 years.

If you add the purchase price and the lifetime costs together, you find out what the product really costs. See the lifetime costs on the list of recommended monitors.
 
Lifetime costs depend on:

  • On, sleep and standby. The time the computer spends in each of these different modes.
  • Lifetime. How many years you expect to have the computer.
  • Electricity price. The Trust bases its calculations on a standard price, but you can also input your own figures

Sample calculation for replacing your monitor
The calculator gives you a precise idea of how much you can save when replacing your monitor with a more energy efficient model. Here is a sample calculation.

  On Sleep Standby Consumption
Current equipment:        
Non energy efficient
17″ CRT monitor		 100 watts 8 watts 4 watts 135 kWh/year
equivalent to EUR 270.00 /year
New equipment:        
Energy efficient 17″ flat screen 30 watts 0,9 watt 0 watt 31 kWh/år 
equivalent to EUR 62.00 /year

 

Annual savings:  
Savings on electricity bill: 104 kWh/year equivalent to EUR 208.00 /year
Total saving: 77 %

 

Savings in lifetime costs:  
Costs over 6 years based on continuing to run the existing equipment: EUR 218.70
Costs over 6 years based on energy efficient flat screen: EUR 50.22
Total saving: EUR 168.48

 

The following assumptions have been factored into the calculation above:  
Time on 1,032 hours
Time sleep 234 hours
Standby time 7,494 hours
Computer lifetime 5 years
Monitor lifetime 6 years
Electricity price EUR 2.00 /kWh
