Office Appliances 101 – Get A Laptop

Hi folks, I’m Jon Mullen the Energy Evangelist. 

Today we’re looking at savings between laptop and desktop computers.

Let me dispel any preferences. I prefer to be able to work anywhere anytime, so I will always prefer a laptop. But then I don’t do any processor intensive video manipulation, or heavy games use (but Chromebooks are now starting to be sold as cloud game stations if your broadband is fast enough).

So back to energy and cost. A solid state disk (SSD) will use less than 25% of the power than a traditional hard disk (HDD). Additionally, the SSD generates practically no heat or sound, so in a modern laptop there is no fan to get rid of excess heat. Have you ever walked into a server room – in a small business there is usually a server being very noisy and the room is reasonably warm (sometimes hot), and the room has an aircon unit. So at least 40% (could be 50% or 60%??) of the electricity used in the room is used to reduce the heat. What a waste. Maybe the heat in the room could be used to heat the rest of the cold offices during the winter months?

But that’s enough info for today.
