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/km/yr at 110m and 12.43 PWh/km/yr at 140m. Concurrently, solar energy can contribute up to 15.16 PWh/km/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.
可再生能源（RE）的开发和利用对于实现可持续发展目标（SDGs）至关重要。中国西北地区拥有丰富的风能和太阳能等可再生能源资源，占全国总资源的 70%以上。评估和利用该地区的可再生能源是实现 SDGs，特别是 SDG7 的关键手段。然而，由于缺乏对可再生能源潜力的了解，实现高质量能源发展面临障碍。因此，我们通过基于地理信息系统（GIS）的多标准分析，评估了中国西北地区的太阳能和风能潜力，定量研究了能源潜力及其对实现 SDGs 的贡献。研究结果表明，中国西北地区可以利用大量的可再生能源，在 110 米处的风速发电可达 9.84PWh/km/yr，在 140 米处的风速发电可达 12.43 PWh/km/yr。同时，太阳能的贡献可达 15.16 PWh/km/yr。新疆省的可再生能源潜力最大，因为它包含了大量具有良好资源质量的适宜区域。研究结果说明了中国西北地区对实现 SDGs 的贡献，并有助于制定更有针对性的资源政策。
