Coal is a black sedimentary rock that can be burned for fuel and used to generate electricity. … Fossil fuels are formed from the remains of ancient organisms. Because coal takes millions of years to develop and there is a limited amount of it, it is a nonrenewable resource.
Why is coal a nonrenewable resource?
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.
Why is coal a good resource?
Cheapest source of energy. It is by far cheaper than nuclear, natural gas, oil. … Unlike other forms of energy (nuclear, natural gas, oil, hydroelectric), coal provides many jobs in removing coal from the earth, transporting it to the utility, burning it, and properly disposing of coal ash.
