Hydraulic Energy

What is hydraulic energy

Hydropower is a kind of renewable energy extracted from the force of falling water.

The best known way of creating hydraulic energy is based on reservoirs where the potential energy of falling water is used to create kinetic energy or energy of movement through turbines that will be transformed into electricity (electrical energy) for human consumption.

Hydro power also called hydro power either hydropower, has been used for thousands of years by humans to create energy. The Greeks, for example, already used water mills to grind wheat into flour more than 2,000 years ago.

The hydraulic power revolution began in the mid-1700s by the Catalan/French engineer Bernard Forest de Bélidor (1698-1761) with his work Hydraulic Architecture (hydraulic architecture in Spanish) where he set the basic parameters for the construction of reservoirs in order to take full advantage of hydropower.

Advantages and disadvantages of hydropower

Hydraulic energy, despite being a sustainable technology, has some disadvantages due to its infrastructure. Some of the advantages and disadvantages of hydropower are:


  • Renewable energy that does not alter the natural cycles of water.
  • It does not need contaminants for energy extraction.
  • Maintenance costs are low.
  • High energy efficiency.
  • By storing water it can be used for other purposes.


  • Reservoirs flood large areas of land, modifying the natural environment.
  • The initial investment for construction is high.
  • The water quality is not high because of the created sediments.
  • The transportation of energy is expensive.
