None. When water freezes it _releases_ energy (the heat of fusion, 333.55 kj.kg). To keep it from freezing, simply keep the energy constant. If the ambient temperature is below zero C (32 F) the rate of energy loss will depend on the temperature of the air and the thermal resistance (insulation value) of the water's container, and other factors such as wind speed. In those conditions you must replace the energy lost to prevent the water from freezing. However, the energy needed depends on the rate of loss, not on the amount of water.
No heat (energy) is required to freeze water (from liquid to solid). Freezing RELEASES energy (heat), as it is an exothermic event. If you want to know how much energy is release, you need to know the heat of fusion for water, and then multiply that by the mass of water being frozen.
2.5 g 1 mol/18.02 g (-285.83) kJ/mol
Realistically none of the worlds energy needs are done in this manner.
I need it for my project too.

2.5 g 1 mol/18.02 g (-285.83) kJ/mol
You need to know the initial temperature.
2.5 g 1 mol/18.02 g (-285.83) kJ/mol
Other comment is wrong 2.5 g 1 mol/18.02 g (-285.83) kJ/mol
A lot

Air compressor alone consumes about 50 to 60 % of energy generated by a gas turbine..
