"If a million PC users switched to a more efficient power supply, it would save almost the equivalent of 250 million litres of gasoline a day."
So if one pc user switched to a more efficient power supply it would save the equivalent of 250 litres of gasoline per day.
Diesel and petrol/gasoline can release roughly the same amount of energy when burnt. My car will do 40 mpg on diesel, that is 2200 miles on 250 litres. So who are the people using pc's that waste so much energy? Where do people get thier figures from about pc power consumption?
