<human>:  What is the difference between renewable and nonrenewable energy sources?
<bot>: The main difference between renewable and nonrenewable energy sources is that renewable energy sources are naturally replenished and therefore can be used indefinitely, whereas nonrenewable energy sources are finite resources that will eventually be depleted. Renewable energy sources include solar, wind, geothermal, hydropower, and biomass, whereas nonrenewable sources include oil, coal, and natural gas. Renewable energy sources are generally considered to be more environmentally friendly, making them a better choice for long-term energy production.
