  • But then you’re just having another system for storing energy, which probably isn’t very easy to implement. An easier solution if you don’t want to use grid batteries is just to improve housing insulation and schedule heating/cooling for non peak hours, so that you are just using less energy overall. The problem in my mind is that that would require a lot of renovation on older homes, which is just more expensive and slower than adding grid batteries. Don’t get me wrong, those changes should be mandated for newer housing, but expecting it to be implemented in older housing probably isn’t gonna happen.



  • There are plenty of alternatives for lithium batteries, chiefly sodium and a redox flow. Heating/cooling is good as well to store, but not every structure is energy efficient enough that it would make much sense. Good thing to work towards, but grid batteries would probably be faster and easier to implement. I have reservations towards pumped hydropower, in part due to watching how hard it is to decommission a lot of hydroelectric dams these days in US as well as the cost to create the areas to hold the water (a lot of the areas that are geographically advantageous for pumped hydropower tend to be nature reserves or national parks, soo…).



  • Not really a course, but Harry Potter and the Methods of Rationality is a pretty good fanfic made with the intent of teaching critical logic concepts and logical fallacies to the reader. I found it a good read, and even if you might dislike some of the literary choices made (Harry makes fast friends with Malfoy, etc), it does cover most of the stuff in a critical thinking textbook in a somewhat approachable manner. It’s free, and you can read chapter by chapter if you just want to give it a glance.
