  • Biomass burning - Release of CO2

  • Fossil fuel burning - Release of CO2

  • Nuclear power - Radioactive wastes

  • Solar energy - Green house effect

Answer

D.

Solar energy - Green house effect

Solar energy is not responsible for green house effect instead it is a source of energy for the plants and animals. Green plants prepare their food by the use of solar energy. CO2 gas is mainly responsible for green house effect. Excess of this gas forms a thick layer around the earth and prevents re-radiation of entering sun rays to atmosphere. Thus, it acts as a glass panel of green house. Therefore, the effect is known as Green House Effect.
