There are many views of nuclear energy that are wrong. Largely as a result of disasters or near disasters such as Chernobyl and Three Mile Island, as well as pop culture such as the Simpsons and various disaster movies.
But nuclear energy can be harnessed safely. The navies of the world have been using nuclear energy to power large ships and submarines for decades, and there are already many nuclear power plants providing electrical energy right now. Countries should invest more resources in improving the efficiency and availability of nuclear energy.
