Den forstår jeg ikke...

Hvis du har et apperat tændt i 24 timer, som bruger 1 Watt, så har det
brugt 24 Wh (Watt-timer). Hvis du ganger det med 365 dage så har du
brugt 8.8 kWh. Med prisen fra Nesa's hjemmeside koster 8.8 kWh 
lige over 15 kr. Så en watt sparet på 24/7 drift, bliver til en
besparelse på 15 kr.
