The Energy for Growing and Maintaining Cities

摘要: Herein we develop a means to differentiate between the energy required expand and maintain economies of cities. A nonlinear model is tested against historical data for two cities, Hong Kong Singapore. robust fit obtained Kong, with maintenance close that growth, while Singapore, weaker fit, growth dominated. The findings suggest decreases in either per unit or demands can simultaneously cause gross domestic product (GDP) total use increase. Furthermore, increasing significantly limit demand GDP. Thus, low especially imply that, all other things being equal, GDP these cities will continue grow, though Singapore’s higher it require more than Kong.
