Which energy category is represented by burning wood for heat?

• A. Biomass
• B. Solar
• C. Geothermal
• D. Wind

Answer: (A)

Biomass energy is energy stored in organic matter like wood, released as heat when burned. The energy in wood originally comes from the sun—plants captured sunlight through photosynthesis, and that stored chemical energy is what you’re releasing by burning the wood. This is different from solar energy, which is captured directly from sunlight with panels or collectors; geothermal energy, which comes from heat inside the Earth; and wind energy, which uses moving air to generate power. So burning wood for heat is a biomass energy source, renewable when sourced and managed responsibly, though it does produce emissions and depends on sustainable harvesting.
