Nuclear Energy
Electricity generated from nuclear fission of uranium-235 or plutonium-239, providing approximately 10% of global electricity with zero direct CO2 emissions.
Formula
E = mc² (mass-energy equivalence); 1 kg U-235 ≈ 80 TJ
Real World
The Hinkley Point C nuclear plant under construction in Somerset is expected to power 6 million UK homes with zero direct CO2 emissions, replacing gas-fired generation that would emit roughly 10 million tonnes of CO2 annually.
Exam Focus
When evaluating nuclear energy, always address both advantages (low carbon, high output) and disadvantages (waste, cost, safety) for full marks.
