The main source of energy in the water cycle is the sun/Solar radiation (sunlight). the source of energy that drives the water cycle is the sun because since the sun's heat makes the water evaporate which will led to the whole process of the water cycle and the process will keep on repeating.
Groundwater Supply & Use. Groundwater is a significant water supply source. The amount of groundwater storage dwarfs our present surface water supply. At any given moment it is 20 to 30 times greater than the amount in all the lakes, streams, and rivers of the United States. Groundwater is also an important source of surface water. It also adds about 492 billion gallons per day to U.S. surface water bodies. Its contribution to the overall flow of rivers and streams in the U.S. may be as large as 50 percent, and it is a major source of water for lakes and wetlands.
