Question

why does the sun emit more energy

Answer 1

Answer:

The Sun has fewer sunspots — dark areas that are often the source of increased solar activity — and stops producing so many explosions, going through a period called the solar minimum. ... That may not sound like a lot, but the Sun emits a large amount of energy – 1,361 watts per square meter.

Answer 2

The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.
