The main difference between renewable and nonrenewable resources lies in their availability and replenishment:
-
Renewable Resources: These resources can be replenished naturally over time. They are sustainable and can be used repeatedly without depleting their availability. Examples include solar energy, wind energy, hydropower, biomass, and geothermal energy. Renewable resources are generally considered environmentally friendly, as they produce little to no pollution during their use.
-
Nonrenewable Resources: These resources are finite and cannot be replenished on a human timescale once they are depleted. They are formed over millions of years and exist in limited quantities. Examples include fossil fuels (coal, oil, natural gas), nuclear fuels (uranium), and minerals. The extraction and use of nonrenewable resources often result in significant environmental impacts, including pollution and habitat destruction.
In summary, renewable resources can be naturally replenished and are more sustainable, while nonrenewable resources are limited and can lead to depletion and environmental degradation.
