Did energy come from either the nuclear or from radioactive solar in earth?

Energy on Earth primarily originates from the Sun through nuclear fusion processes occurring in its core, where hydrogen atoms combine to form helium, releasing vast amounts of energy. This solar energy drives weather patterns, photosynthesis, and various ecosystems. Additionally, radioactive decay within the Earth contributes to geothermal energy, but it is not a primary source compared to solar energy. Thus, while both nuclear processes contribute to energy, solar energy from the Sun is the dominant source for life on Earth.
