Is Nuclear Energy Renewable
No it's not, it takes uranium and that is not something that is renewable. Nuclear energy supposedly is carbon-neutral, meaning no CO2 is release into the air as energy is produced. Which is true.
But they kindly forget that in order to mine uranium, you need a lot of diggers, drills and so on, which operate a-lot CO2. Not to mention the toxic radioactive waste nuclear energy produce, that will stay lethal for a few more thousand years and for which huge concrete vaults need to be built... and concrete production uses loads of CO2 too.
