Which statement describes solar energy as renewable on a broad scale?

Solar energy is renewable on a broad scale because the Sun provides energy continuously for billions of years, so its supply is effectively inexhaustible for human needs. Daily and seasonal fluctuations come from day and night and weather, but these do not run out the total amount of energy available. Because we can collect energy when it’s sunny and store it for use later, solar can power large-scale electricity systems despite those fluctuations. The idea that solar energy is finite, cannot be stored, or comes from non-renewable decay doesn’t fit how solar power works on human timescales.
