Question 1 • TPS EdX Biology

Which scenario describes a renewable resource being used for energy?

Answer
A
A turbine creates electricity using a gasoline-powered motor.
B
A school heats its classrooms with a natural gas furnace.
C
A factory fuels its furnaces with coal.
D
A power company generates electricity using a river’s current.

Explanation

A renewable resource is naturally replenished on a short timescale. A river’s flowing water can drive turbines to generate electricity, so using the river’s current is renewable. Coal, gasoline, and natural gas are fossil fuels that take millions of years to form, so they are not renewable.
