Mo8-L4b: What are Renewable and Nonrenewable Resources

Geothermal plants transfer thermal energy from the Nonrenewable energy resources are energy
Earth to water, creating steam that turns turbines in resources that are available in limited amounts or
electric generators. that are used faster than they can be replaced in
nature.

and coal.

split apart in a process called
nuclear f ssion.

Biomass includes wood, plants, manure, and garbage, Most of the energy used in the United States comes
all of which are sources of stored chemical energy that from nonrenewable energy resources.
can be transformed to electric energy in energy plants.
