The city of Zhangjiakou urgently needs to transform its conventional energy-dependent industries as it co-hosts the 2022 Winter Olympic Games and is the only National Renewable Energy Demonstration Zone in China. The study reveals that under the integrated scenario, Zhangjiakou's greenhouse gas emissions would peak in 2030, showing competitive advantages of renewable energy in terms of emission reductions, job opportunities, and economic costs. This highlights the importance of pursuing feasible low-carbon pathways and co-benefits strategies in future renewable energy transformation efforts.
A successful transformation from conventional to renewable energy can contribute to climate change mitigation and regional development. As the co-host city of the 2022 Winter Olympic Games and the only National Renewable Energy Demonstration Zone in China, Zhangjiakou urgently needs to transform its conventional energy-dependent industries. This paper establishes a Long-range Energy Alternatives Planning System (LEAP)-Zhang model to examine the environmental and socio-economic effects of renewable energy development in Zhangjiakou by projecting the energy consumption and associated greenhouse gas emissions by various sectors over the 2016-2050 period. Two scenarios are designed, i.e., the business as usual scenario (BAU) and the integrated scenario (INT) (including three sub-scenarios, i.e., renewable energy alternatives scenario (REA), industrial structure optimization scenario (ISO) and energy saving facility scenario (ESF)). Results indicate that under the INT scenario, Zhangjiakou's greenhouse gas emissions would peak in 2030 with 13.23% of lower energy consumption when compared with the BAU scenario. Compared with the conventional energy, renewable energy shows competitive advantages in terms of greenhouse gas reduction, employment opportunities and economic costs. The total number of employees would reach 0.15 million by 2050 under the INT scenario, 1.71 times more than that in the BAU scenario. Feasible low-carbon pathways and co-benefits strategies associated with industrial transformation and renewable energy substitution should be pursued in future actionable plans. Results found in this study could provide importance information for achieving renewable energy transformation and associated socio-environmental benefits within and beyond China.
