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 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 .
Program personality modeling away from urbanization below time limitations during the China
Regardless of if metropolitan extension do accelerate energy practices 17,18,19 , the latest motor vehicle stamina feabie Hesap Nasıl Silme play with is likely to associate negatively towards urbanization peak on account of economic climates away from level 20,21,22 . As an instance, significantly more urbanized components into the Canada ate down for each capita opportunity 23 . Additionally, full energy consumption of rural property try larger than that of metropolitan properties, given that over 85% away from outlying domiciles explore unproductive solid fuel twenty-four . Predicated on Customer Analysis Platform, 275 locations worldwide play with hydropower, 189 metropolises explore cinch energy, and you may 184 towns and cities play with solar power solar pv power. No less than 100 urban centers play with renewable energy to get to 70% off energy, such as Seattle, Oslo, Vancouver, and Nairobi. In the usa, 58 metropolitan areas, plus Atlanta and you can Hillcrest, possess plans to change to one hundred% tidy and renewable power. On the current technical and energy storage, it is likely to go one hundred% renewable power likewise have all over the world and you can get to zero carbon dioxide pollutants because of the 2025. The worldwide fuel age group structure for the 2050 is anticipated once the lower than: solar power photovoltaic (69%), piece of cake strength (18%), hydropower (8%), and you will biomass (2%), having energy sites batteries covering 29% off power consult. It’s listed that every of earth’s premier dams and you can stamina flowers have been in Asia, if you’re Yunnan Province and Guizhou Province lead 30% regarding China’s hydropower. The latest Jinsha River alone possess a great 9-peak dam. The latest energy from these hydropower is privately transmitted so you can Guangdong and you will Hong kong through the high-current grid. As a result of the abundant hydropower information designed for cooling, Guizhou State has recently end up being China’s main data cardio feet. In 2018, Fruit Corporation oriented the fresh new iCloud data cardio during the Guizhou. Pretty much every high They team away from Asia possess developed data locations inside Guizhou, including Alibaba, Huawei, and China 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.
