Learn what solar energy is, how it's harnessed and processed, and pros and cons of solar technology. Solar energy is the radiant energy from the Sun that can be harnessed using various technologies. Learn about the global potential, benefits and challenges of solar energy, and how it relates to other renewable sources. What Is Solar Energy? Solar energy is defined as the transformation of energy that is present in the sun and is one of the renewable energies. Once the sunlight passes through the earth’s atmosphere, most of it is in the form of visible light and infrared radiation. Solar energy is the power harnessed from the sun’s rays, converted into heat or electricity using different technologies. The most common way we use it today is through solar panels (photovoltaic cells), which capture sunlight and turn it into usable electricity.
