Nobel Prize Winner's Premonition About Nuclear Energy Comes True

From Investing Trends | Ad

Nobel Prize-winning physicist Dr. Burton Richter made a controversial statement 15 years ago. Despite skepticism, he predicted that more nuclear power was needed to help combat the damaging effects of a changing climate.

As it turns out, he was correct... Experts now advise that nuclear power is the ONLY realistic way for the world to meet climate goals and achieve energy independence.

Will This Nuclear Revival Send Uranium A Bull Run?
