如何解决城市能源供应难题?

Cities hold about half of the world's population but account for 60 per cent of its energy use, according to the International Energy Agency, which is backed by developed country governments.
根据得到发达政府支持的国际能源署(IEA)数据，城市养育了全球约一半的人口，却消耗了占全球使用量60%的能源。

Many of the problems of urbanisation – local pollution, greenhouse gas emissions, provision of services and economic development – are linked to energy use.
城市化的很多问题——环境污染、温室气体排放、服务配套和经济发展，都与能源消耗有关。

In emerging economies, cities typically consume more commercially provided energy than rural areas. City dwellers are more likely to have access to electricity, to own energy-hungry consumer goods, and to work in places that need to be powered.
在新兴经济体，城市对商业化供应的能源消耗量往往超过农村地区。城市居民更有可能获得电力供应、拥有高耗能的消费品并在需要用电的场所工作。

Rural areas typically use much more biomass such as wood and animal dung for cooking and heating, so their total energy consumption is often higher. But the demand for coal, gas and power is greatest in cities. In China, cities use twice as much commercial energy per capita as the countryside.
在农村，利用柴火和动物粪便等生物质来生活做法和取暖的情况，往往会比城市里普遍得多。因此，农村能源消耗总量通常更高。但在城市，人们对煤炭、天然气和电力这几种形式的能源需求量最大。在中国，城市人均商业化供应的能源消耗量是农村的两倍。
