1. Yes, if pressed to, you would get it, in a better or worse way. At least you know what to do, if not how. You would know which plants are manageable, how to schedule crops, how soil needs to be aerated, watered and fertilized. You can figure out suitable replacements to everything if you put just a bit of mind to it. People, even simple, can pull off feats of intellect when pressed. 2. The most accessible power technologies are wind and tidal power. Plus you can use human and animal power easily enough. And it is easy enough to make big unwieldy batteries. This is at most 16th century tech with initial development in ancient times and was initially done with ancient equipment. As long as someone remembers how it is done and how electricity and motors work, it would get done. The hardest part is metallurgy and more advanced chemistry. That took centuries to figure out very well, though a lot can be done with wood or reed. You can do a lot without semiconductors or with very junk big ones scavenged from about anything. Scavenging plastics is easy too. 3. The biggest risk would again be personal security and mental health. These risks cannot be avoided but can be mitigated. Medicine would be set back by centuries. Advanced food preservation techniques would be unavailable... Leisure would be very limited at least initially.
