do i get partial credit professor?

I am not sure, but please correct me if i am wrong. Is the reason that the condtions are anoxic, which lead to lower rate of decomposing, and bog water primarily will not have stuff to digest humans otherwise (probably either stuff which does photosynthesis, or small filter feeders), so you would be kinda preserved. And if the bog is actively developing, you may descend, and eventually be stuck preserved (or whatever is the appropriate term for it)

this may seem stupid/naive, but geothermal does not have any such problem. it is effectively a ac (heat pump). Nuclear too does not require complex manufacturing. it still requires mining, but so do almost all electrical solutions too. but beyond that, they are just rocks that pretty much perpetually dissipiate heat. if you go for betavoltaics, they directly give electrons, and can charge stuff.

sadly, no - you still need high quality silica, and advanced facilities to manufacture the photovoltaics. Imagine it like you buying coal and using coal to power your house. yes this coal is cleaner, and runs for 10-20 years, but there are not many coal plants.
