Nie and Kemp [51] investigated the increase of energy con-
sumption in China during the period of 2002–2010 using data from China statistical yearbook 2011
and China energy statistical yearbook 2003–2011. They investigated the impact of changes in
appliances, floor space, population, and energy source mix. The main factor contributing to energy
consumption increase was appliances, followed by floor space per capita, with the energy mix the
less important, and population the most stable. In order to predict electricity use, the authors
developed regression based predictions to investigate the relationship between electricity
consumption and ownership of appliances. The main conclusion was that the consumption of
electricity will continue to rise
despite a gradual saturation of demand.
