If you get annoyed by vague ‘area the size of Wales’ statistics then ‘Without hot air’ is well worth a read. Professor David Mackay has done the calculations and provides detailed models for how Britain could become sustainable in terms of energy production and consumption.

is used up in one second of car-driving.
The energy saved in switching off the charger for one year is
equal to the energy in a single hot bath.”
