Non-Renewable Energy: Fossil Fuels & Nuclear | GCSE Physics
Non-renewable resources will eventually run out and often have significant environmental impacts.
What is the main byproduct of burning coal?
What is Non-Renewable Energy: Fossil Fuels & Nuclear | GCSE Physics?
"Energy from sources that cannot be replaced once they are consumed."
Which law states that energy cannot be created or destroyed?
Why can efficiency never be 100% in a mechanical system?
A 5 kg weight is lifted 2 metres. Calculate its GPE (g = 9.8).
Which formula is used to calculate kinetic energy?
Fossil Fuels
Fossil Fuels: Coal, Oil, and Natural Gas (release CO2 when burnt).
Nuclear: Uranium or Plutonium used for fission (no CO2, but radioactive waste).
Fossil fuels contribute to the greenhouse effect and global warming.
Nuclear energy is highly reliable and has high energy density.
Common Error: Thinking nuclear energy is "renewable" because it doesn't release CO2. It is non-renewable because the fuel supplies are finite.
