PickVidsBest Renewables, batteries & storage Videos
「Renewables, batteries & storage」下面有89部被不同的人、在不同月份推荐过的视频。挑的时候先看对象：入门4部，适合还没学过的人；进阶16部，适合已经懂术语的人；普通向69部，按兴趣就能看；更硬的0部，留给想看推导或细节的人。这一类数量最多的是讲解，所以它们的共同点是用一个图像或类比把一个概念补上。常出现的频道包括Technology Connections、Everything Electric CARS、Real Engineering。目录给这个主题划的范围是：Renewable energy: solar, wind, hydro, geothermal, batteries, lithium, hydrogen, grid storage, energy transition, solar panel technology, energy efficiency economics.如果只看三部，就从《Václav Smil at Driva Climate Investment Meeting 2019》开始，它负责把问题讲出画面；然后看《Why Heat Pumps are Immensely Important Right Now》，换一种讲法或例子；最后看《Michael Moore Presents: Planet of the Humans | A Film by Jeff Gibbs | Full Documentary》，留给已经有基础的人。页面按每页24部切开，顺序看的是被推荐跨越了多少个月，不是播放量。每条标题下面那一句是这部片子自己的内容说明，用来区分它在讲定义、过程、演示还是观点。点进去能看到推荐原话、原文链接和适合谁看。看的时候把强烈推荐当成有人明确叫你去看，把引用当成只是拿来举例，把批评留下来对照，不要把每条评论都当成同一力度。
