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. Layers of dirt and rock covered the plants over millions of years.
What is non renewable source of energy?
Non-renewable energy comes from sources that will run out or will not be replenished for thousands or even millions of years. … Most non-renewable energy sources are fossil fuels: coal, petroleum, and natural gas. Carbon is the main element in fossil fuels.
Why coal is good source of energy?
Coal is a stable, secure energy source
Coal also has the unique advantage of being able to be stored on-site, providing weeks or even months of fuel supply at the power plant. This important characteristic contributes to grid reliability, resiliency and reduces fuel supply bottlenecks.
Is coal considered an infinite source of energy?
A non-renewable resource won’t be replenished and will eventually run out. Coal is a finite resource because the conditions that were in place to form coal are long gone.
What are the 4 main non renewable sources of energy?
