Energy and its transformations
Energy sources
Energy sources are natural resources from which we obtain different forms
of energy.
uses
industrial uses
Examples
construction...
agriculture
household uses
Examples
means of transport...
heat for cooking
ways
By availability in nature and capacity for regeneration
Renewable
Non-renewable
By origin
primary
secondary
By use in each country
conventional
Non-conventional
By environmental impact
Clear or non-polluting
pollutants
Electricity
Electricity is the most widely used form of energy for two reasons
It can be transported long distances inexpensively
It can be easily transformed
electric power plants
Electric power plants are facilities where primary or secondary energy
is transformed into electricity,
to produce electricity they use a turbine-alternator system.
Transport and distribution of electrical energy
Electricity cannot be stored; therefore, it must be transported to
consumption centres.
conventional electric power plants
nuclear power plants
This type of plant includes a nuclear fission reactor to move the turbine rotor. And uranium is the main fuel used
Their advantage is the high return on their energy production
Hydroelectric power plants
This type of power plants uses the
height of the stored water in a dam, converting it into kinetic energy.
Pump-driven hydraulic power plants
Gravity-driven hydraulic power plants
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.
Non-conventional electric power plant
Wind power plants and wind farms
Use the kinetic energy of the wind
Solar power plants
Use the energy from the sun
Geothermal power plants
use the heat found at deep levels in the earth.
Biomass thermal power plants
all organic compounds that are produced through natural processes
Ocean power plants
use the energy from the seas and the oceans
Environmental impact
Waste treatment
To reduce the waste generated by thermal power plants, as well as their effects, we can do different things. For example install special filters.
Waste from nuclear power plants is stored in drums with thick sides that don't let the nuclear radiation escape
Environmental impacts
Energy consumption is preceded by a long process, consisting of several stages.
Fuel transport
Extraction of natural resources
Final energy use
Electricity generation
Environmental impact assessment
As part of a technical proiect, it's obligatory to carry out an environmental impact assessment to find out what changes it would provoke in the environment
Some solutions
Energy diversitification
Energy sanvings
Efficiency
