Final answer:
Renewable fuels can be replaced by natural processes, examples include sunlight, wind, and biomass. Non-renewable fuels exist in limited amounts, examples include coal, oil, and natural gas.
Step-by-step explanation:
A renewable fuel is one that can be replaced by natural processes as quickly as humans use them. Examples of renewable fuels include sunlight, wind, and biomass. Sunlight can be converted into electricity using solar panels. Wind energy is harnessed using wind turbines. Biomass can be burned to produce heat or used to create biofuels.
On the other hand, non-renewable fuels exist in limited amounts and cannot be easily replaced. Examples of non-renewable fuels include fossil fuels like coal, oil, and natural gas. These fuels took millions of years to form and cannot be replenished at the rate they are being consumed. Non-renewable fuels are widely used for electricity generation, transportation, and heating.
