The laws of thermodynamics: what role in the energy transition?

The best debating point around the first law of thermodynamics is the nuclear energy industry, which creates energy from the controlled decay of Uranium-235. To all intents and purposes, nuclear energy is "creating energy". But the first law of thermodynamics is upheld by claiming that all matter is really just condensed energy (via the law of special relativity, E =
