This has a lot more to do with consumption than with production. Most of these islands are small, and it’s unrealistic for them to have large populations or a heavy tourist industry without desalination plants. Energy needs to become cheap, and honestly, wind farms and solar can help with this.
This is silly. The web is not in decline and Google is not at fault. Most of the web is garbage, and Google helps us find the information buried in a sea of ads and repetitively copied/reworded content. We are moving to a world where putting up a plagiarized page with tons of ads will not be profitable. The sooner that day arrives, the better.
