SOURCES OF ENERGY
RENEWABLE
HYDROPOWER ENERGY
It is the generation of electrical energy produced from hydraulic power. In 2015, hydroelectric power generated 16.6% of the world's total electricity and 70% of all renewable energy
capture the energy of falling water to generate electricity. A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy
BIOMASS ENERGY
It is obtained from the breakdown by bacteria, in a controlled way, of organic matter (organic waste). The generation of electricity based on biomass energy is the conversion of the chemical energy of the gas into mechanical energy through a combustion process
Biomass contains stored energy from the sun. Plants absorb the sun's energy in a process called photosynthesis. When biomass is burned, the chemical energy in biomass is released as heat. Biomass can be burned directly or converted to liquid biofuels or biogas that can be burned as fuels
EOLIC ENERGY
It moves a propeller and by means of a mechanical system the rotor of a generator, usually an alternator, which produces electrical energy is rotated. ... When used to produce electricity it is called a wind turbine generator.
it transforms wind energy into mechanical energy by means of oblique blades attached to a common axis. The rotating shaft can be connected to various types of machinery, be it for grinding grain (mills), pumping water or generating electricity
SOLAR FOTOVOLTAIC ENERGY
The sunlight affects the photovoltaic cells of the plate, creating a field of electricity between the layers. This is how an electric circuit is generated, which is primarily responsible for the operation of photovoltaic solar energy
The device that allows to transform the photovoltaic solar energy is the solar cell or photovoltaic cell. Photovoltaic systems allow the transformation of sunlight into electrical energy, that is, the conversion of a particle with light energy into voltaic energy
SOLAR THERMAL ENERGY
It consists of harnessing the sun's energy to produce heat that can be used to cook food or to produce hot water for domestic water consumption
It consists of transforming solar energy into thermal energy stored in a fluid. Devices called manifolds are used to heat the liquid.
NO RENEWABLE
-
NATURAL GAS
It is generated from the decomposition of organic matter under the action of bacteria in the diagenetic stage or
from the decomposition of organic matter, but controlled by temperature
-
COAL
Is formed from the decomposition of vegetables such as leaves, branches, barkthated in swampy and humid areas
METHODS OF EXTRACTION
Modern surface mining / Strip Mining /
Contour mining / Mountaintop Mining Removal / Underground mining
extract the coal using the technical open pit calls. Open pit mining recovers a larger proportion of coal than underground methods. Open pit mines can cover areas of approximately several square kilometers and use longer pieces of equipment
it consists of removing the sterile material above the coal mantles, following the contours along a ridge or around a hillside
remove the rocks above the coal mantles in long cuts or strips. The rocks of the first strip are deposited in an area outside the mining area. The rocks of the subsequent cut are deposited as filler in the previous cut removed. Usually the process involves drilling the rock strip attached to the previously excavated strip
it involves the removal of mountain tops to expose coal seams, and the removal of debris associated with mining in adjacent "filling valleys"
Most coal cracks are too deep for open pit mining and require underground mining, a method that currently accounts for about 60 percent of global coal production, It consists of making an underground mine while the carbon is extracted from the pillars and sides
NUCLEAR ENERGY
It is generated by a process in which the atoms of a material called uranium disintegrate. The energy that uranium releases when its atoms disintegrate produces heat with which the water found in nuclear reactors is boiled
In nuclear fusion, energy is released when atoms combine or merge with each other to form a larger atom; This is how the Sun produces energy and currently this procedure is not practicable despite being in the process of development. In nuclear fission, atoms separate to form smaller atoms, releasing energy; nuclear power plants use this technique to produce electricity
