Non-renewable energy resources

• Non-renewable resources refer to energy sources that are limited and can't be quickly replaced in nature.
• These resources have taken millions of years to form and can be depleted much faster than they are replenished.
• Examples of non-renewable resources include fossil fuels like coal, oil, and natural gas, which are extracted from deep underground reserves.

Characteristics of non renewable energy resources 

• Non-renewable energy sources have a finite supply and are not easily replenished.
• These sources deplete over time, without the possibility of renewal.
• They often have negative impacts on the environment, including pollution and greenhouse gas emissions.
• Logistical challenges may arise as they often require transportation for refining and distribution.
• They are not always available locally and require a regular supply of unrefined materials from different regions.
• Their installation costs are comparatively lower in the short term.
• Unlike wind or solar farms, they do not demand a large area for production.
• Their existing scale advantages make them affordable for the end consumer.
