Nuclear energy will not get traction because one of the main goals of the climate change fraud is to induced artificial scarcity of energy.
Because this is what reptilians from Nibiru want?
These ridiculous straw-men are the creation of your trainers designed to keep people of a certain fairly low caliber satisfied without any intellectual exploration. They obviously have nothing to do with the subject at hand.
To answer your question: it's because this is what those who control the energy sector want. Once the rights to, say, hydrocarbon resources have been pinned down and solidified then it is economically desirable to achieve a high price for the resource rather than a low one. Scarcity is one tool which helps achieve this.
The really amusing thing is how fear, guilt and shame are used to make the peeps blame themselves and happily pay the extra price for what is actually age old and fairly simple market manipulation.
