IT Energy Facts
Power saving equipment
- Typical electrical load of a desktop computer (monitor and system unit) while operating = 120W – 130W.
- Electrical load after power-saving equipment is activated = 20W – 30W.
Therefore, power saving equipment operates with 20% less energy than a typical desktop setup.*
- Switch off screen rather than leaving in ‘sleep mode’
- If you choose a flat screen instead of an ordinary PC monitor, 88kWh is saved yearly.
This corresponds to an annual saving of about €13 on the annual electricity bill.
- Computer monitors use 60% of the total power of the computer.
- Only 10% of people turn off their monitor when they leave their desk for 30 mins.
Leaving a PC monitor on all night wastes enough energy to microwave 6 dinners
- In an office with 10 PC monitors left on overnight, enough energy is wasted to run 8 dishwasher loads/13 washing machine loads.
- The average computer sucks down 35.5 watts when on standby.
Ave. ‘On’ mode = 82.2watts, Ave. ‘Passive standby’ = 35.5 watts
Therefore, the average computer uses 43% of its total energy on standby*
- The average laptop uses 16.5 watts when on standby
Ave. ‘On mode’ = 34.1 watts, Ave. ‘Passive standby’= 16.5 watts
Therefore uses 48.4% of its total energy on standby*
- Configure your computer to ‘energy saving mode’ or turn off…
- Turning off your computer at night instead of leaving it on will save on average 25% of its annual energy bill.
- Turn off when you’re not using for more than an hour.
