Which of the following is not a renewable source of energy?
A. Hydrocarbon fuel
B. Water energy
C. Solar energy
D. Wind energy

Hint: The “renewable” term is frequently used for those energy resources and technologies whose common characteristic is that they are non-depletable or naturally renewable.

Complete answer:
Renewable energy is energy produced from sources that never deplete or can be replenished within a human’s lifetime. These energy sources include solar energy, wind energy, hydro energy, tidal energy, geothermal energy, and biomass. Renewable energy sources are the most abundant and freely available sources.
Water energy: Water energy is the power resulting from the motion of water. This energy can be generated by building a dam or barrier which is a large reservoir to create a controlled flow of water that will drive a turbine to generate electricity.
Solar energy: It is an essential source of renewable energy. The conversion of solar energy into solar power can be performed by different technologies such as photovoltaic systems, concentrated solar power, and solar water heating.
Wind energy: Wind is a plentiful source of clean energy. To generate electricity from wind energy, turbines are used to drive generators that feed electricity into the National Grid. Wind power is the most sustainable and cost-effective energy source.

So, the correct answer is ‘hydrocarbon fuel’.

Note: Nonrenewable energy sources take millions of years to regenerate themselves. These resources include fossil fuels, coal, natural gas, crude oils, etc.
Most nonrenewable resources are formed from organic carbon material which is heated and compressed over time, changing their form into crude oil or natural gas.
