Srishti was on summer holidays trip to her grandparent's village. She was excited to go on tour to the farmland with her grandfather. While on farmland, her grandfather showed her a biogas plant. He explained to her that bio-mass energy (energy from bio-fuels such as Wood, bio-gas and Alcohol) may be a renewable source of energy because if trees are cut from the forests for obtaining fire-wood, then more trees can be grown in the forest in a short period of time. Although, wood is a renewable source of energy, yet it should not be used on a large scale since if so then, there will be a depletion of the forests leading to an imbalance in nature. Srishti thanked her grandfather for making her understand the bio-mass energy concept.
Should we use wood as a fuel on a large scale? Justify with reasons.

All the students of class 10th were excited as they were on a school trip to a Tehri Dam. During the Dam visit, the science teacher Mr. Sharma showed them the hydro-electric power generation plant. Mr. Sharma explained the students that the electricity produced from the kinetic energy of the flowing water is called hydro-electric power and a plant which generates hydro-electric power is known as a hydro-electric power plant. In order to produce electricity, a high-rise dam is built to stop the flowing water.
