      Though wood is a renewable source of energy, but the use of wood as a fuel is not a wise decision. Explain.

    Answer:

                      Wood is a renewable source of energy. It is obtained by cutting trees. A new plant sapling usually takes more than 15 years to grow and mature into a tree. Therefore, replenishment of cut down trees takes a very long time. Cutting down of trees causes depletion of the forests leading to imbalance in nature. Due to unsuitable air and the above reasons, usage of wood as a source of energy is not a wise decision.
