Towards sustainable development goals: Assessment of wind and solar potential in northwest China.

The development and utilization of renewable energy (RE) is crucial for achieving the sustainable development goals (SDGs). The northwest China, endowed with abundant RE sources such as wind and solar power, accounts for over 70% of the country's total resources. The assessment and utilization of RE in this region has become a critical means to achieve the SDGs, particularly SDG7. However, lack of knowledge regarding the RE potential poses a barrier to achieving high-quality energy development. Thus, through a Geographical Information System (GIS) based multi-criteria analysis, we assess the solar and wind energy potential in northwest China, quantitatively examine the energy potential and its contribution towards achieving the SDGs. Our results show that a substantial portion of RE can be harnessed in northwest China, with wind energy generation reaching up to 9.84PWh/km2 /yr at 110m and 12.43 PWh/km2 /yr at 140m. Concurrently, solar energy can contribute up to 15.16 PWh/km2 /yr. Xinjiang province has the highest RE potential for it contains a large share of suitable area with good resource quality. The findings illustrate the contribution of northwest China towards achieving SDGs and facilitate the formulation of more targeted resource policies.
