I’ve read through some of the topics on the first page of this section and saw of all the ways that energy can be harvested, used, stored, how efficient it is, how much it costs, etc. Now, I’m just a sappy 19-year old boy and the closest thing that makes me qualified about this subject is that took an economics class in high school and got an A+ (not including extra credit) and took a year pf physics and got an A-. However, obviously being as young as I am I have an opinion on everything and a computer with internet so here it is, and obviously I will be wrong in some parts so feel free to point it out.
I believe that geothermal (after wind and solar) energy would be the most efficient, that is depending on the placing of where they decide to build this facility or if they decide to build more of them than this could pertain to those as well. In my opinion it would also be the most cost effective as in there would be more space above the ocean for more houses where people can live (more people = more money) and as well as more restaurants that will have more people going to them and more gyms having more people go them, you see my point. In my knowledge most of the energy harvesting and storing would take under the facility where as if it were solar or wind then there would be room on/above it dedicated for those reasons thus less space for people that live there and possibly even less room for more important things and they’d have to make sacrifices due to having less space, as little as they would be taking up, but when you’re in the middle of an ocean I would think that every inch counts. Obviously though the closer the facility is to a tectonic plate or underwater volcano then the more energy can be acquired with the least amount of loss due to distance and transportation and it can be harvested 24 hours a day unlike wind or solar which may not always be there (especially solar).
Like I said earlier if there are any mistakes to what I’ve brought up go ahead and let me know.
