The energy in the form of heat is absorbed by the water to convert itself into vapour during the process of evaporation. This energy is then released in the atmosphere when the water vapor gets converted into clouds during the process of condensation. From the start of the water cycle , the heat energy of the sun gets converted into the kinetic energy to raise the water vapour to certain height. After reaching heights Kinetic energy is converted into potential energy and then it is finally released to atmosphere after condensation. In the entire process the total energy remains constant it is just being converted from one form to another.
