Energy from burning wood is an example of which energy category?

• A. Solar Energy
• B. Nuclear Energy
• C. Wind Energy
• D. Biomass Energy

Answer: (D)

Energy from burning wood is biomass energy because the heat comes from chemical energy stored in organic matter that came from living organisms. When wood burns, the chemical bonds in the plant material release energy that we can use as heat. Biomass energy specifically refers to energy derived from organic matter like wood. Solar energy would come from sunlight, nuclear energy from atomic reactions, and wind energy from moving air—none of which describe burning wood. If forests are managed sustainably, biomass can be a renewable energy source as the organic material can regrow and absorb CO2 again.
