Which energy source is produced when sunlight is converted into electrical energy or thermal energy?

Explanation:
Sunlight can be turned directly into energy, which is solar power. Photovoltaic cells in solar panels convert light into electricity, while solar thermal systems use concentrated sunlight to heat a fluid, producing usable heat. This direct conversion from light to energy is what makes solar power the correct choice. Hydroelectric power uses the energy of moving water, geothermal taps heat from inside the Earth, and wind energy relies on moving air to run turbines. While these sources are all useful, they do not arise from converting sunlight directly into electrical or thermal energy.
