The rapid urbanization in China has been associated with a growing hunger for energy consumption and steadily-increasing CO_dos emissions. In this paper, an integrated system dynamics model composed of four sub-models is developed to simulate the urbanization and energy consumption in China from 1998 to 2050. Three scenarios are provided: accelerated economic development, emission reduction constraint, and low-carbon oriented. The result reveals that rapid economic growth and sufficient energy supply will foster China’s urbanization in all three scenarios. Under the low carbon transition scenario, China’s urbanization rate is expected to reach % in 2050, both reducing carbon emissions and promoting eco-friendly development. All three scenarios witness a dramatic growth of residential energy consumption and a steady increase of industrial energy consumption. China still has a long way to achieve the low-carbon transition goal. China should promote renewable resources and energy, pursue a low-carbon lifestyle, and reduce energy intensity over the next few decades.

Inclusion

There is a long and rich history of research exploring the association between energy demand and urbanization 1,2,3 . Energy consumption, and its socioeconomic and environmental impacts, have imposed a critical influence on urban sustainability 1 . At the same time, the effects of urbanization on energy consumption vary across scales and over countries 4,5,6 . China’s dramatic urbanization and the associated energy demand as well as the pressure of CO2 emitted by such energy consumption is a major global scientific issue since this century 7,8,9 . Previous research in China has often focused on a specific field or aspect, such as urbanization theory 10 , urbanization procedure 11 , energy policy 12 , energy growth 13 , CO₂ emission 14 , climate change 15 , and public health 16 .

System figure model away from urbanization not as much as time limitations within the Asia

Whether or not metropolitan expansion carry out speeds times usage 17,18,19 , brand new motor vehicle fuel fool around with has a tendency to correlate adversely toward urbanization top due to economies out of measure 20,21,22 . As an example, so much more urbanized section in Canada consumed straight down for every single capita time 23 . As well, full opportunity use of rural property is actually larger than that metropolitan properties, since over 85% from rural houses use unproductive solid fuel twenty four . Centered on Consumer Data Platform, 275 places internationally use hydropower, 189 places fool around with breeze power, and you will 184 urban centers use solar solar pv power. At the very least one hundred metropolises fool around with renewable energy to get to 70% away from fuel, such as for example Seattle, Oslo, Vancouver, and Nairobi. In the usa, 58 metropolises, and Atlanta and you may Hillcrest, features intends to transition to a hundred% clean and renewable power. Into the established technical and energy shop, it is anticipated to reach one hundred% renewable power have worldwide and you can get to no carbon dioxide pollutants by the 2025. The worldwide electricity generation build for the 2050 is anticipated since the less than: solar power solar pv (69%), wind strength (18%), hydropower (8%), and biomass (2%), with time stores battery packs layer 30% away from electricity consult. It is indexed that most of one’s world’s largest dams and you may fuel plants come into Asia, when you’re Yunnan Province and you may Guizhou State contribute 30% regarding China’s hydropower. The latest Jinsha River by yourself keeps a great nine-level dam. The new fuel produced by this type of hydropower is really transmitted in order to Guangdong and Hong kong from the higher-voltage grid. Considering the abundant hydropower resources designed for air conditioning, Guizhou State has recently getting China’s primary analysis heart ft. From inside the 2018, Apple Enterprise dependent brand new iCloud research cardiovascular system from inside the Guizhou. Every high It business from China features created analysis facilities within the Guizhou, including Alibaba, Huawei, and you can China Mobile.

Urbanization is a non-linear open complex system, with multiple subsystems dynamically interacting with each other 25,26,27 . Dramatic urbanization under energy constraints is challenging for China, which has topped all the countries in population, energy consumption (since 2010), and CO₂ emissions (since 2008) 27 . To systematically examine the causality mechanism between energy consumption and urbanization, the SD (system dynamics) model has been widely used in the domains such as energy consumption 28 , energy policy 29,30 , energy efficiency 31 , carbon emission 32,33 , and energy industry 34,35 . The SD model, Monte Carlo simulation, and Hornberger-Spear-Young (HSY) algorithm were employed to analyze the urbanization patterns with the limit of energy and environmental resources 36 . In addition, the baseline scenario was simulated from 2005 to 2020 using the SD model of urbanization and the energy consumption complex system 28 . The SD model was also developed using the STELLA platform to model the energy consumption and CO₂ emission trends 33 . To dynamically predict future urban development trends under various scenarios has very important scientific values for the policy formulation.
