nonrenewable energy

Nonrenewable energy sources are those that do not replenish at a sufficient rate for sustainable economic extraction in meaningful human timeframes. These include fossil fuels such as coal, oil, and natural gas, as well as nuclear energy, which are finite and contribute significantly to environmental pollution and greenhouse gas emissions. The primary users of nonrenewable energy are industries, power generation companies, and transportation sectors, but there is a growing emphasis on transitioning to renewable energy for sustainable development.
