Which of the following is the source of non - renewable energy?  

Non-renewable sources of energy are finite and derived from Earth's finite reserves. The primary categories include fossil fuels, such as coal, oil, and natural gas, formed over millions of years from decayed organic matter.

 Key Points

• These resources are extracted and burned to generate electricity, but their combustion releases greenhouse gases, contributing to climate change.
• As global energy demand rises, transitioning to sustainable alternatives becomes imperative for a cleaner, more resilient future.
• Renewable sources of energy are sustainable, environmentally friendly alternatives that harness natural processes to generate power.
• These sources are replenished naturally and don't deplete over time. Few examples are Solar Energy, Wind Energy, Hydroelectric Power etc.

Therefore the correct answer is Coal.
