Answer: C. Wind
Renewable resources are natural resources capable of replenishing and replacing the portion depleted by consumption either through natural reproduction or some other recurring processes carried out in a finite amount of time. Some examples of renewable resources are hydropower, wind energy, solar energy, geothermal power, and biomass. Biomass is organic material gotten from plants and animals like sewage, wood, and ethanol. These energy sources can never be depleted and as such, are able to supply a continuous and consistent source of clean energy.
Non-renewable resources, on the other hand, are not capable of replenishing and replacing any portion consumed in a finite amount of time. In other words, non-renewable resources cannot be gotten back once consumed and even if they are replaced eventually, it will take an extremely long period of time to happen. While renewable resources are very safe and less costly, non-renewable resources are generally hazardous to the earth, very costly, and difficult to maintain.
