Policy makers need enough power generation capacity to meet the demand, despite the still incomplete regulatory system in many countries.

👉reverse the trend

[rɪvɜ:(r)s]★reverses, reversing, reversed

[VERB]When someone or something reverses a decision, policy, or trend, they change it to the opposite decision, policy, or trend.

可以看到原文中是没有出现「燃油车」这个词的，可见这是翻译在处理时的增译，但是这样处理明显更加符合中文语境，表意也更加明确。

switch用作名词，reverse用作动词，这是我之前不熟悉的用法，新技能get✔️

👉broken system of regulation

用broken来形容system还真是我没有想到的。broken比较多用来形容marriage和engagement, 破碎的婚姻和毁约了的婚约，难道原文是将system of regulation比作婚约了？
