PickVidsBest Power grid, heating & buildings Videos
「Power grid, heating & buildings」下面有68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6部，适合还没学过的人；进阶4部，适合已经懂术语的人；普通向58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、Practical Engineering、Kirsten Dirksen。目录给这个主题划的范围是：Electric power systems: power grid failures, Texas ERCOT, transmission, utilities, heat pumps, HVAC, home electrification, building efficiency, insulation, energy at home.如果只看三部，就从《Heat Pumps: the Future of Home Heating》开始，它负责把问题讲出画面；然后看《James Burke Connections, Ep. 1 "The Trigger Effect"》，换一种讲法或例子；最后看《Why Heat Pumps are Immensely Important Right Now》，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。
