1077 - What is the main source of energy on Earth provided by the Sun?

The main source of energy on Earth provided by the Sun is solar radiation. This energy is harnessed from sunlight and eventually becomes various forms of energy such as:

• Heat (keeping the Earth warm)
• Wind (through evaporation and air movement)
• Fossil fuels (plants grew using sunlight and over time formed into coal and oil)
• Hydroelectric power (water evaporates with sunlight, then flows back to Earth as rain, filling rivers and dams)

This energy also supports photosynthesis, allowing plants to grow and provide food for humans and animals.
