So I'd like to suggest an alternative that comes from the red regions.

所以我想推荐一个来自红色区域的替代方案。

There's enormous potential for cleaner EV battery production in all these yellow and red regions if we dig deeper and find ways to tap into the underground heat whether there's underground water or not.

在所有这些黄色和红色区域，如果我们挖掘得更深，找到利用地下热量的方法，那么无论是否有地下水，都将有巨大的潜力来生产更清洁的电动汽车电池。
