Which energy category includes resources derived from solar radiation?

The category that includes resources derived from solar radiation is solar energy. Solar energy is harnessed directly from sunlight, making it a unique form of energy among other categories. This type of energy can be converted into thermal energy (heat) or electrical energy using solar panels and other technology designed to capture solar radiation.

Understanding solar energy's role is critical, especially considering its sustainable nature and the increasing reliance on renewable resources to reduce environmental impacts. By focusing on solar radiation, this energy category emphasizes the utilization and potential of the sun as a power source, distinguishing it from other energy forms such as nuclear, which relies on atomic reactions, or mechanical, which derives from motion. Electrical energy can indeed be generated from solar sources, but it is not categorized specifically as energy derived from solar radiation itself, rather it is a result of converting solar energy.
