In a hydroelectric dam, the energy delivered to the electrical grid is in which form?

Electrical energy is the form delivered to the grid. In a hydroelectric dam, gravity makes the water flow turn a turbine, giving the system mechanical energy. The generator then converts that mechanical energy into electrical energy, which is what's sent out through power lines to the grid. The other forms—chemical energy, thermal energy, and sound energy—do not represent the main energy carried by the grid in this setup, even though some energy may be lost as heat or vibrations.
