Just a correction: The sun doesn't give Earth energy. Earth radiates into space exactly as much energy as its given by the sun. The 2nd law of thermodynamics states that in a closed system energy is preserved. Energy is neither created nor destroyed, it is transformed and "degraded" into more difficult to use forms of energy. What the earth is given by the sun is energy that is highly usable, that is, low entropy. Veritaseum has a whole video on the matter if you are interested in more info.

To answer your actual question, the Earth's mass is relatively stable. It does slowly lose some of the lighter gasses of the atmosphere as well as it radiates some particles. But what is loss is kinda compensated by stuff (mainly asteroids and such) incoming from space.
