The reason for considering coal as nonrenewable and biomass as a renewable source.
Answer to Problem 46R
The coal takes a long year to produce while wood grows in some years, so coal is considered as nonrenewable and wood as renewable.
Explanation of Solution
Introduction:
Those energy sources that are produced faster than used are called renewable and those sources that are used faster than produced are called nonrenewable sources of energy.
The coal is a fossil fuel and produces by the thousand years of decomposition, so the coal is considered as a nonrenewable source of energy.
The wood can grow for the use and it produces faster than the use of the wood, so the wood is considered as the renewable source of the energy.
Conclusion:
Therefore, the coal is considered as nonrenewable and wood as renewable.
