If you specifically take 100 kilos of core material from the Sun, then it would be a no contest victory for the Sun. But the Sun is very, very big, and when it comes to producing energy, most of it is doing absolutely nothing. So it brings the average energy production per kilo way, way down.
i kinda do no get it, can you explain it in some other way?
like, 100 kilos of sun would generate less heat energy than 100 kilos of me?
Yes. On average.
