Answer:
A non-renewable source of energy is coal.
Step-by-step explanation:
The mineral coal is a brown or black rock, of sedimentary origin, that comes from organic matter, so it is considered a fossil fuel.
Currently, coal is used as an energy source, since its combustion produces a great amount of heat. However, the speed with which coal is consumed is faster than its production —which can last millions of years— so it is considered a depletable or non-renewable energy source.
The other options, such as hydroelectric, solar and wind energy are renewable energy sources.
