all mechanical energy will eventually be converted to heat by friction.
energy can neither be created nor destroyed, but can change form. Eventually all power used is dissipated into the surroundings in the form of heat, unless it drives an endothermic chemical reaction and gets turned back into chemical energy again.

If your PC draws 200W of power from the mains, for instance, it will be putting out 200W of heat as well.

But if that surprises you, this will surprise you even more.

you're right and wrong...
All energy dies eventually go to heat (vibration of molecules), but your assumption that the temperature of the earth will increase has a key flaw, that the earth is a closed system. In reality, most of the extra energy that we produce will also be lost to space as radiation. There will be a change in the equilibrium point, but it will be small.
Think of it like a fridge, our energy use is like putting a bulb in the fridge, greenhouse gas build up would be like opening the door (not a great analogy, but hopefully the intent is clear?
apologies for erroneous worda, this is done on my phone
