Minimising the quantities consumed
The conventional view is that you can only reduce the quantity consumed by investing in physical modifications to plant, systems, buildings and vehicles, with a view to improving their underlying efficiency. But experienced energy managers will tell you that you also need to minimise the risk of avoidable excess consumption which can arise at any time for various reasons, some foreseeable but others quite unexpected. These effects impose what is often a hidden excess cost burden on the enterprise, but avoiding these costs is usually quick, easy, and cheap.

A really comprehensive attack on the question of quantity-reduction will also include two issues of management policy: developing standards and guidance for design and operation of systems, buildings and vehicles.
