Office Appliances 101 – Switch It Off!

Hi folks, I’m Jon Mullen the Energy Evangelist. It’s a new month and we’re looking at savings on office appliances. So where do we start?

Let’s state the obvious. If it isn’t switched off then it’s using power. I’ve seen some clients set their computer so it doesn’t switch off. One of the reasons they give is because they think the device will last longer. Sorry to those out there who believe this, but that is a load of bull! Or another excuse is that it takes too long to boot up in the morning. So let’s work out the difference. A normal office pc is on for 8 hrs a day monday to friday and possibly 46 weeks of the year if we take into account holidays. So let’s take a current electricity price of 14p per 1000 W of electric, and a standard pc will use 100 watts plus the monitor is an additional 50 watts. So a year costs (14p * ((150/1000)*8hrs)) * 5 days per week * 46 weeks in the year = £38.64. So if I left the computer on all the time because it “takes too long to switch on the pc” – (14p * ((150/1000)*24hrs)) * 7 days per week * 52 weeks in the year = £183.45. That’s a difference of £144.81. How many computers do you have in your office? It quickly adds up. Another way of looking at it is when you walk into a room which has a computer running all day every day. You always notice the heat in the room. All of that heat is usually from the computers and it’s usually wasted.
