Fossil Fuels
Hydropower
Renewable: Air, Sun, Wind, Hydropower
Nonrenewable: Fossil Fuels
Renewable resources:
1. Air: Air is considered a renewable resource because it is constantly replenished through natural processes such as photosynthesis and the water cycle.
2. Sun: The sun is a renewable resource as it continues to provide solar energy without depletion.
Nonrenewable resources:
1. Fossil Fuels: Fossil fuels (such as coal, oil, and natural gas) are nonrenewable resources because they are formed from the remains of ancient plants and animals that took millions of years to form, and they cannot be replenished within a human lifespan.
2. Hydropower: Hydropower itself is not a resource but a form of energy generation. The resource behind hydropower is water, which is renewable. However, the process of harnessing hydropower can affect the environment, making it a topic of debate whether it is entirely renewable or not.
3. Wind: Wind is a renewable resource as it is naturally replenished by atmospheric convection and solar radiation.
