Hydro cycle.

Like most of the other renewables, hydro-electric power is solar radiation as a result. The Sun starts the hydrologic cycle, water evaporating from the surface of the Earth that, subsequently, the precipitate and flowing over the surface of the land is able to provide this energy.

Facts of hydroelectric energy.



1.Hydroelectric power is a form of renewable energy.

2.Around 20% of the electricity used in the world it comes from the hydroelectric power.

3.In few places still hydroenergy transformed it into mechanical energy.

4.Almost all of the hydropower exploited in the world transforms it into electrical energy.

5.It is a completely clean energy, does not emit gases, does not produce toxic emissions, and does not cause any kind of acid rain.

Hydroelectric Energy.

Today we investigated about hydroelectric energy, since we think that in this way you can become more easy learning and possible solution of our project question.

To be able to generate hydroelectric power, we need a large amount of running water or water reservoir.

This large amount of water needed to operate, some machines called rotating turbines.The turbines are intended to move generators that convert energy generated by the turbines (mechanics), in electric power.

 

 

 





The process to be able to generate electricity through Hydro begins when:

 

-The Sun heats water in oceans, rivers, dams or reservoirs, generating a process of evaporation.

-Evaporation rises and creates clouds which eventually produce rain, then flowing through the aforementioned media.

-The water of these media, has a lot of power mechanics, therefore the hydroelectric power are located strategically to take advantage of this power, since not being located at short distances, the friction of the water with the beaches, rocks, animal, among other things they may have these means water would the loss of all potential energy.

Question

What Security measures are taken to build a hydroelectric, to be friendly to the
environment and health of people?

Objectives
· Discover new means by which to carry out a hydro healthier for the environment.

· Identify a hydroelectric plant damage done to the environment and people.

· To be able to know if several mini hydro are friendlier to the environment

IntroductionWater is one of the most used natural resources for energy production, due to its
easy access and economics of it. In its liquid form, water is used to generate
electricity through the use of hydraulic turbines, which convert hydraulic
energy into mechanical energy is used to turn electric generators work. Most
electrical energy used in the world is generated in large hydro, which make use
of the river water contained in dams, which are artificial barriers which
stores and controls the flow of the waters of way to have permanent
availability of the energy from them. The aim of this paper is to design a
hydroelectric plant in the 145 MW generated. This will select the river in
which to install the plant as well as turbines and flow rate used.

Theoretical Framework
Hydroelectric plants are not friendly to the environment as it destroys ecosystems under
water, how can we reduce the environmental damage? One of the solutions that
come to mind is to build several mini-hydro, as not being a dam, and be several
mini-hydro do not need high costs or complete technical studies are needed.
Each mini hydro can serve as a source of energy in a home or even a town.
