Bio energy cannot be converted into which of the following forms of energy?

chemical energy

The correct answer is Option 2: chemical energy

Bio-energy can be converted into:

• electrical energy (through biogas plants and biomass power generation),
• gas for cooking (such as biogas),
• heat energy (by burning biomass).

However, bio-energy itself is already a form of chemical energy stored in organic matter. Therefore, it is not converted into chemical energy.

NCERT: " Bio-energy refers to energy derived from biological products which includes agricultural residues, municipal, industrial and other wastes. Bio energy is a potential source of energy conversion. It can be converted into electrical energy, heat energy or gas for cooking. It will also process the waste and garbage and produce energy. This will improve economic life of rural areas in developing countries, reduce environmental pollution, enhance self-reliance and reduce pressure on fuel wood. One such project converting municipal waste into energy is Okhla in Delhi."
