Counting the carbon cost of our love affair with computers, the programme discovers that every twitter or Facebook posting has an energy demand far higher than we might realise.

The expanding digital cloud contributes 2 per cent of global emissions of carbon dioxide, about the same as aviation, and it's rising.

But how can they be made greener and more efficient? Costing the Earth investigates.
