They have calculated in 2007 I generated 3.5 tonnes of CO2 and for 2008 it will be 4.6 tonnes (problem of having additional folks in the house).
Its a far cry from my HIPS report which thought I should be emitting 12 tonnes or if I did all their recommendations 10 tonnes.
Averaging out the red line (my domestic 2007 combined energy consumption) gives me a figure of about 95kwh/d which for 2 people in the house is about 48kwh/d each.
In his talk he reckoned that UK people use about 125, in the USA about 300. With Heat at 38kwh/d and light of 4kwh/d plus gadgets of 5kwh/d it looks as though his numbers are spot on. Read his latest book in pdf form here . To see his other predictions and also read Davids blog.
