Li et al. present a worldwide analysis of rare-earth elements used in wind turbine generators. It focuses on the most extreme deployment scenario using rare-earth-intensive generator technology to demonstrate demand quickly outpacing supply, thus suggesting an existential threat to rapid wind deployment. However, alternative generator technologies exist or are in development that significantly reduce or almost eliminate the need for rare-earth elements.

风力发电机技术研究旨在满足全球风力发电的雄心

Li等。提出了对风力发电机中使用的稀土元素的全球分析。它着重于使用稀土密集型发电机技术的最极端部署方案，以证明需求迅速超过供应，从而暗示了对快速风力部署的生存威胁。但是，替代发电机技术已经存在或正在开发中，可以大大减少或几乎消除对稀土元素的需求。
