ENERGY AND ITS TRANSFORMATION
Energy sources
Household uses
Industrial uses
are natural resources from which we obtain different forms
of energy that can be transformed for a specific use
Electricity
is the most widely used form of energy in industnalised societies
It can be easily transformed and It can be transported long distances
Electric power plants
are facilities where primary or secondary energy
is transformed into electricity, Once electricity is generated, it must be
transported to towns, cities or industrial parks.
Transport and distribution of electrical energy
are usually located far away from the points where
the energy is used — for safety reasons, space requirements or physical and
geographical considerations
Coventional electric power plants
Nuclear power plants
This type of plant includes a nuclear fission reactor that produces the
pressurised steam needed to move the turbme rotor.
Fossil fuel thermal power plants
At this type of power plant, water is heated in a boiler by the heat
generated from the combustion of a fossil fuel, usually natural gas or coal
Combined cycle power plant.
Efectricity ts generated as a result of two combined cycles. A cycle that uses air and gas, and a conventional thermal cycle Dunng the first cycle, augments or mcreases the
a gas turbine is used that includes a compressor.
Hydroelectric power plants
This type of power plant uses the potential energy provided by the
height of the stored water in a dam, converting it into kinetic energy. This energy moves the blades of the turbine
Non-conventional electric power plants
Wind power plants and wind farms
These power plants use the kinetic energy uf the wind to move the blades of a rotor at the top of a tower, this is referred to as the
wind turbine.
Solar power plants
These plants use the energy from the sun.There are two main types of instaflations: photo-thermal and photovoltaic power plants.
Geothermal power plants
These plants use the heat found at deep levels in the earth. This heat
may reach the surface in the form of steam, gases or hot water.
Biomass thermal power plants
Biomass consists of all organic compounds that are produced through natural processes
Ocean power plants
These power plants use the energy from the seas and the oceans. The
concept is to use three types of energy from the sea.
Environmental impact
Environmental impact assessment
As part of a technical proiect, it's mandatory to carry out an environmental impact assessment to find out what changes it would
provoke in the environment
An environmental study must also assess both the economic and social consequences of the project in the area, to decide whether or not to go
ahead with the plan.
Environmental impacts
Energy consumption is preceded by a long process, consisting of several
stages, each ol which has an environmental cost
Extraction of natural resources
Fuel transport
Electricity generation
Final energy use
Waste treatment
To reduce the waste generated by thermal power plants, as well as their effects, several measures can be taken.
Waste from nuclear power plants is stored in drums with thick
sides that do not let the nuclear radiation escape.
Some solutions
possible solutions to alleviate some of
the environmental problems are
Efficiency.
energy efficiency policies increase efficiency of everyday appliances and devices.
noticeably reduce the energy we consume
Energy savings.
essential to reduce the consumption of ag forms of energy — without seriously affecting quality of life. adoption of more environmentally
friendly habits
Energy diversification.
use of renewable energy sources
is fundamental. objective is to produce a large
part of our eiectricity through alternative power plants.
