Hydro energy is made in the kinetic and potential energy of a water body. As a river flows, it carries along with it some kinetic energy that can be harnessed using certain types of turbines.

When a river flows from a higher level to a lower level, it loses its potential energy. This can be trapped by using a dam.

Hydro energy is made due the fact that the water has some potential energy in it. This is obtained because of the hydro cycle.


Hydrologic cycle

The Sun, which drives the water cycle, heats water in oceans and seas. Water evaporates as water vapour into the air. Ice and snow can sublimate directly into water vapour. Rising air currents take the vapour up into the atmosphere where cooler temperatures cause it to condense into clouds. Air currents move water vapour around the globe, cloud particles collide, grow, and fall out of the upper atmospheric layers as precipitation.

Some precipitation falls as snow or hail, sleet, and can accumulate as ice caps and glaciers, which can store frozen water for thousands of years. Most water falls back into the oceans or onto land as rain, where the water flows over the ground as surface runoff. A portion of runoff enters rivers in valleys in the landscape, with streamflow moving water towards the oceans.

Runoff and water emerging from the ground (groundwater) may be stored as freshwater in lakes. Not all runoff flows into rivers, much of it soaks into the ground as infiltration. Some water infiltrates deep into the ground and replenishes aquifers, which can store freshwater for long periods of time. Some infiltration stays close to the land surface and can seep back into surface-water bodies (and the ocean) as groundwater discharge. Some groundwater finds openings in the land surface and comes out as freshwater springs.

 

Precipitation

Condensed water vapor that falls to the Earth's surface . Most precipitation occurs as rain, but also includes snow, hail.


 

Snowmelt

The runoff produced by melting snow.


 

Runoff

The variety of ways by which water moves across the land. This includes both surface runoff and channel runoff. As it flows, the water may seep into the ground, evaporate into the air, become stored in lakes or reservoirs, or be extracted for agricultural or other human uses.


 

Evaporation

The transformation of water from liquid to gas phases as it moves from the ground or bodies of water into the overlying atmosphere. The source of energy for evaporation is primarily solar radiation. Evaporation often implicitly includes transpiration from plants, though together they are specifically referred to as evapotranspiration. occurs over the ocean.

Sublimation

The state change directly from solid water (snow or ice) to water vapor.


 

Condensation

The transformation of water vapor to liquid water droplets in the air, creating clouds and fog.


 

Transpiration

The release of water vapor from plants and soil into the air. Water vapor is a gas that cannot be seen.


In this cycle, the water that gets trapped in the rivers and dams end up as the useful energy which can be used for production of electricity. Thus the sun plays a vital role in the water cycle.
