Why can modern factories be energy inefficient?
One common misconception in energy efficiency is that a modern factory with modern machinery is energy efficient. Overall it will be much better then an old factory with old kit, but that does not mean it is as efficient as it could be.
Why is this? Well the key missing ingredient is staff behaviour.
Many companies run energy saving campaigns in small groups rarely interacting with the staff around them. If they do communicate their plans they often fail to achieve employee buy in.
It is important to get staff buy in as they are the ones interacting with your machinery on a daily basis. So if they leave machinery on idle or heating to early this all contributes to energy wastage.
