what are non renewable energy sources
Fossil fuel (such as oil, petroleum, natural gas and coal) and radioactive fuel (uranium) are the most common non-renewable energy sources. These resources are indeed renewable, but the fact that it takes thousands of years to grow or generate them, makes them non-sustainable and therefore non-renewable. non-renewable energy resource can be defined as an energy resource that cannot sustain its consumption rate. In other words, non-renewable energy is not sustainable. The energy reserves will inevitably be empty if we continue to use them.
