I finally had some time for hard numbers. (I hope I didn't mess the units.)

From https://en.wikipedia.org/wiki/World_energy_supply_and_consum...

> In 2019 TES was 606 EJ and final consumption was 418 EJ, 69% of TES.

It looks like 75% of it is from fossil fuels. In a power plant that produces electricity, the output is less than a half of the heat produced by the oil/coal/gas. So 606 * .75 * 2 that is like 1000 EJ. In a simplified world, all that energy becomes heat that escape to space after a while.

To get the mass, you must divide it by c^2 https://www.wolframalpha.com/input?i=1000+ExaJoule%2Fc%5E2 and the result is 1200kg (24000 pounds) per year. That's like launching to deep space an elephant per year or a small car per month.

The total mass of the Earth is approximately 6×10^24 kg. So per year we are "launching" 2×10^-21 of the mass of the Earth, that is impossible to notice.

Fake Edit: I just noticed that I forgot to include the heat produced by natural radioactivity that is higher than the energy we use. It's probably also a small number compared to the mass of the Earth, but it's left as an exercise for the reader.
