Thanks for reaching out! Are you wondering about the heat released from human uses of energy, like power plants, industry, etc? If so, here’s a quick calculation of the effect of that compared wit h the increase in CO2 and other greenhouse gases.
The current primary energy usage worldwide is around 600 EJ/yr, which is a little less than 20 TW. All of this is eventually dissipated into heat.

The increased heat trapping from CO2 currently amounts to around 2.16 W/m2, which is around 1100 TW (over the 510 trillion square meters of Earth’s surface).

So, the heat generated by all energy usage worldwide is only about 2% of the current greenhouse effect due to the extra CO2 in the atmosphere.
