    Uranium generates that energy by fission. The hydrogen in sugar could generate huge amounts of energy if fused.

        It figured out photosynthesis instead. Why do your own fusion when you can just take advantage of the fusion that’s already happening?

      And this boulder could generate huge amounts of energy if I pushed it up to the top of Mt. Kilimanjaro and let it roll down.

      For comparison:

      • Chemical combustion of uranium: ~4.7 MJ/kg
      • Nuclear fission of uranium-235: ~83.14 TJ/kg (or $ 83.14 \times 10^6 , \text{MJ/kg} $)
