We accept that fact that world energy consumption will increase, not decrease.
Despite the fact that the energy consumption of the average household fridge in Canada has decreased by over 50% in the period from 1990 to 2004, the overall domestic energy consumption of the residential sector has increased by about 10% in the same period.
We will continue to make efficiency gains on existing technologies, but it is naïve to think that these will not be negated by increased consumer spending on new technologies (think about how many people owned a computer in the 1970’s).
In fact the Energy Information Administration predicts a 50% global increase in energy consumption from 2005 levels by 2030. What we need to achieve is the decoupling of energy consumption from CO2 emissions. The climate change issue is an emissions problem, not a necessarily a consumption problem.
