What are the main sources of non-renewable energies

The main sources of non-renewable energy are:

• Fossil Fuels: These are formed from the remains of ancient organisms over millions of years. They include:
  • Coal: A solid fuel formed from plant matter.
  • Petroleum (Oil): A liquid fuel formed from marine organisms.
  • Natural Gas: A gaseous fuel, often found with petroleum deposits.
• Nuclear Energy: This is derived from radioactive elements, primarily uranium, through a process called nuclear fission.

These sources are considered non-renewable because they are consumed much faster than they can be naturally replenished.
