I was anticipating a negative take on Solarpunk based on the title, but it's actually quite a well made video with good points. I do wish she had touched on the ideology behind solarpunk (Anarchism), but otherwise good stuff.
Over on the r/Solarpunk community on reddit, there's often debates as to what constitutes solarpunk, with many arguing that AI and greenwashed buildings should count. I've even seen an argument for solarpunk being compatible with capitalism once or twice, and this video would make for a good rebuttal.
I was surprised to learn a year ago that window AC units with heatpump heating are now available. I imagine they're a good option when combined with a good window seal.
