“I would like nuclear fusion to become a practical power source. It would provide an inexhaustible supply of energy, without pollution or global warming.” -Stephen Hawking
Climate science is a hotly debated area, with many disputing the robustness and ethical motivations of the scientists in the field. But even if you throw everything we know about carbon dioxide, global warming, and climate change away, there’s still an energy crisis coming in the long term. The fact is, fossil fuels will someday, hundreds of years from now, run out if we extract and burn them all.
Meanwhile, solar, wind, hydroelectric and other renewables will forever be inconsistent, and the infrastructure needed for using both generates large amounts of pollutants. But there is one power option that could satisfy everybody, while eliminating both pollution and the risks of running out of fuel or power inconsistency: nuclear fusion. While nuclear fission does have substantial downsides, there’s no risk of a meltdown with fusion.
