The rapid urbanization in China has been associated with a growing hunger for energy consumption and steadily-increasing COdos 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 hitch buluÅŸma 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.
Addition
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 .
Program personality modeling from urbanization less than opportunity limitations inside the Asia
Though urban expansion carry out accelerate times consumption 17,18,19 , the fresh automobile electricity use sometimes correlate negatively for the urbanization top on account of economies out of scale 20,21,twenty-two . As an example, a lot more urbanized parts when you look at the Canada consumed all the way down each capita times 23 . On the other hand, full times usage of outlying house is actually bigger than that of urban homes, as the more than 85% from rural homes fool around with ineffective solid fuel twenty four . Centered on Buyers Investigation Program, 275 towns around the world have fun with hydropower, 189 metropolises use wind strength, and 184 urban centers have fun with solar photovoltaic energy. At least 100 metropolises use renewable power to reach 70% regarding energy, eg Seattle, Oslo, Vancouver, and Nairobi. In the usa, 58 cities, also Atlanta and you will San diego, keeps intentions to transition in order to one hundred% neat and renewable power. For the present tech and energy shops, it is expected to get to one hundred% renewable power likewise have around the globe and you may go no carbon emissions by 2025. The worldwide power age bracket framework when you look at the 2050 is anticipated once the less than: solar solar pv (69%), piece of cake energy (18%), hydropower (8%), and you will biomass (2%), with energy shops electric batteries coating 29% regarding stamina consult. It is detailed that every of one’s planet’s premier dams and electricity flowers come in China, if you are Yunnan State and you can Guizhou State contribute 29% away from China’s hydropower. Brand new Jinsha Lake by yourself has actually an effective nine-peak dam. Brand new power from these hydropower are directly transmitted so you’re able to Guangdong and you may Hong kong from large-current grid. Due to the abundant hydropower tips designed for cooling, Guizhou Province has recently end up being China’s main analysis cardiovascular system legs. Within the 2018, Apple Enterprise created the fresh iCloud data cardiovascular system into the Guizhou. Almost every higher They organization out-of China possess put up investigation centers from inside the Guizhou, and additionally Alibaba, Huawei, and Asia Cellular.
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.
