Solar energy is the radiant light and heat from the sun that has been harnessed by humans since ancient times using a range of ever-evolving technologies.
"Solar energy offers many benefits that make it one of the most promising energy forms. Renewable, non-polluting and available planet-wide, it contributes to sustainable development and job creation where it is installed."
The Sun is an extremely powerful energy source, and sunlight is by far the largest source of energy received by Earth, but its intensity at Earth’s surface is actually quite low.
