Is it really worth it?
What is it?
"Nuclear energy is the energy in the nucleus, or core, of an atom. Atoms are tiny units that make up all matter in the universe. Energy is what holds the nucleus together. There is a huge amount of power in an atoms dense nucleus. In fact, the power that holds the nucleus together is officially called the "strong force”. Nuclear energy can be used to create electricity, but it must first be released from the atom. In nuclear fission, atoms are split to release the energy." - National Geographic
How it works
While "creating" energy, the atoms don't release any type of gas that is consider bad for the environment, like methane or carbon dioxide, for example. It's consider a green energy.
The construction process is expensive, because requires a lot of infrastructure, but once this part is done, you will have powerful energy being produced by a low cost.
High Energy Density
Is estimate that the energy released in the process is ten million times bigger that the one released with fossil fuel atom.
Nuclear reactors' waste needs to be placed in a far and safe place. And that takes a lot of time and space
Uranium is the main fount of nuclear energy and it's an element that can't be found in all countries and is not renewable, so once you've used, you will never be able to use it again.
Even a small leak and/or explosion can create huge damages. Even a small particle of radiation can least trough many years and created huge risk to human life.
