Green energy refers to energy generated from natural sources that are environmentally friendly and have little or no carbon emissions. Examples include solar, wind, hydro, geothermal, and biomass energy. It is considered “green” because it has minimal impact on the environment compared to fossil fuels.

Difference from renewable energy:

• All green energy is renewable, but not all renewable energy is green. For instance, large hydropower projects are renewable but may lead to ecological damage and displacement, making them less "green."

• Green energy emphasizes sustainability and minimal pollution, whereas renewable energy focuses on source regeneration.

Green energy is crucial for combating climate change, reducing air and water pollution, and achieving energy independence. It plays a vital role in helping countries meet their net-zero emissions goals. For example, India's National Solar Mission and the International Solar Alliance are pushing for wider solar adoption, which is both green and renewable.

Thus, while both terms are related, green energy prioritizes environmental impact, making it a more holistic concept.
