Is solar energy renewable or nonrenewable resource? Why?

Solar energy is a renewable resource because it originates from the sun’s nuclear fusion reaction, which continuously generates a vast amount of energy. Although this reaction consumes hydrogen as fuel, the sun has an abundant supply and can continue delivering energy to the Earth for billions of years. The sun’s nuclear fusion reaction produces more hydrogen, providing a sustainable source of fuel.
