i still like my hydroelectric idea.
there's a problems with this.
People: People are scared of a nuclear meltdown, and a majority of people are willing to shoot down the idea with past incidents, Fukushima, Three-Mile Island accident, and Chernobyl. Also it's been a popular misconception spread by anti-nuclear activists that the waste produced by nuclear power-plants is not properly contained, and is ran off into the ocean and our water sources. Some politicians back my previous statement.
Fukushima was a minor incident that only occurred because of massive damage. Chernobyl was a piss poor Ukrainian station that melted down in what, the 80s? Three Mile Island is still in use today, didn't melt down.
Waste produced by power plants is stored on-site now and perhaps one day we will figure out whether it's ok to just shove it in the desert of Nevada. Until then, it's pretty safe.
Regardless, it's going to take multiple sources of power to completely power the world. Plus geographically, some power sources don't even make sense in separate regions.
