An example of a non-renewable resource is coal. Coal is a fossil fuel formed over millions of years from the remains of ancient plants under high pressure and heat. Once extracted and used for energy, it cannot be replenished within a human timescale, making it a finite resource. Non-renewable resources, including coal, oil, and natural gas, are pivotal for powering industries, generating electricity, and fueling transportation. However, their extraction and use can lead to significant environmental impacts such as pollution and climate change, prompting a shift towards sustainable energy sources.
