Seriously, nuclear energy is not the devil. It's pretty much unlimited energy and safer than oil.
I guess Chernobyl and Fukushima scared a lot people.
There is no denying that a nuclear reactor going boom is a lot more damaging than other type of electric plants having a meltdown. On top of that, the nuclear waste problem has not been fully solved either, even though it's not as much of a problem as some people think it is.
It's not a long term solution (as in, for decades), but it's a shitload better than gas or coal. It would be great as an intermediate solution, to help phase out combustible power, while renewable power is developing.
However, the main concern is costs. Building and maintaining a nuclear plant is expensive, and takes a long while to set up. That's an investment that a lot of companies today are not willing to make. If they're gonna be switching over to better methods in 25 years, then why would you invest in something that's only gonna return on your investment in 30 years? (spitballing the numbers here)
Governments just have to find the fucking balls to start banning the more polluting type of plants, and force the companies to invest more in other types of energy. Be that nuclear or wind or solar or hydroelectric.
Of course, it's easy for us to just say these kind of things, when we have zero expert knowledge or experience in the field. It seems so simple for us novices, but it's a lot more complex and delicate than we make it out be.
