Ford has instigated an energy-saving programme across its business, saying actions as simple as shutting down computers at night and weekends can make huge savings.

It estimates that 60 per cent of its employees globally don't shutdown their computers at the end of a working day. Doing do, it says, would save 16,000-25,000 metric tonnes of carbon dioxide a year and $1.2m (£800,000) in energy costs.

As a result, Ford is installing a new programme on its computers to maximise power saving potential. This will include a managed shutdown of all computers each night and weekend.

Phone chargers use approximate zero power when not charging. Even when they're charging how much power do you think it takes to recharge your phone? Answer: Very little.

For computers it's really the accessories that take power, such as an external USB hub. The PC itself isn't bad. Where you have a switched mode power supply they'll be very efficient.

Sky Digiboxes now switch in to standby at night, offering savings of a few watts of power too. But even when they're running they're very efficient. From memory running a standard light bulb took more power.

Guilty is energy efficient light bulbs! Why? Because they don't give as much light as they claim, quickly fade to half brightness and need replacing much much more often than they're supposed to because of this. So for the same brightness of a standard bulb you're having to use more of these. Added that they're more complex to manufacture, and you've lost your "green" credentials. Edison had it spot on....

Not guilty is modern electronics on standby.

I've always tried to ensure that I switch off these types of items, not always successfully, but have recently acquired an electricity useage guage and it certainly concentratesthe mind when you can see exactly how many pence per hour that TV on standby or set of spotlights is costing. I'm sure we could all benefit from having a smart meter or something similar as and when they are rolled out by the electricity companies.
