The correct answer is Coal energy.

• Non-Renewable Source of Energy
  • Non-renewable energy comes from sources that will run out or will not be replenished in our lifetimes.
  • Most non-renewable energy sources are fossil fuels like coal and petroleum.
• ​Renewable Source of Energy
  • The wind, the sun, and Earth are sources of renewable energy.
  • These energy sources naturally renew or replenish themselves.
• Coal energy
  • Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.
  • Coal is classified as a nonrenewable energy source because it takes millions of years to form.
  • Coal contains the energy stored by plants that lived hundreds of millions of years ago in swampy forests.
  • The extraction and use of coal cause many premature deaths and many illnesses.

• Tidal energy
  • Tidal energy is harnessed by converting energy from tides into useful forms of power, mainly electricity using various methods.
  • Tidal energy has potential for future electricity generation.
  • It can be seen as a long-term energy resource that does no harm to human beings in the form of any pollution and also is available in abundance.
• ​Wind Energy
  • Wind energy, or wind power, is created using a wind turbine, a device that channels the power of the wind to generate electricity.
  • The wind rotates the blades of the turbine, which are attached to a rotor.
  • The rotor then spins a generator to create electricity.
• ​Solar Energy
  • Solar energy is any type of energy that is generated by the sun.
  • ​Solar energy is the cleanest and most abundantly available source of energy.
  • The most common form of solar energy is harnessed by solar panels or photovoltaic cells.
