Why can't you renew oil and natural gas?

Oil and natural gas are fossil fuels formed over millions of years from the remains of ancient organic matter. Their formation requires specific geological conditions and vast time scales, making them non-renewable resources. Once extracted and consumed, they cannot be replenished within a human timespan, leading to depletion of reserves. This contrasts with renewable energy sources, like solar or wind, which can be naturally replenished over short periods.
