ENERGY
Non-conventional electric power plant
WIND POWER PLANTS
uses the kinetic energy uf the wind to move
the blades of a rotor at the top of a tower
powered by the blowing wind
SOLAR POWER PLANTS
use the energy from the sun
there are 2 types
Photo-thermal power plant
Photovoltaic power plant
GEOTHERMAL POWER PLANTS
These plants use the heat found at deep levels in the earth
BIOMASS 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
ENERGY SOURCES
Clasification
By availability in nature and capacity for
regeneration
Renewable
non renewable
By environmental impact
Clean or non-polluting
Pollutants
By use in each country
CONVENTIONAL
NON CONVENTIONAL
By origin
SECONDARY
PRYMARY
HOUSEHOLD USES
INDUSTRIAL USES
ELECTRICITY
Electric power plants
facilities where primary or secondary energy
is transformed into electricity
how do they work?
2 The turbine turns mechanical energy into the rotating movement
1 An alternator has a fixed part connected to the turbine shaft
3 As the rotor shaft moves, alternating electrical current is produced
the most widely used form of energy
because
I t can be easily transformed into other forms of energy
It can be transported long distances inexpensively
Transport and distribution of electrical energy
Electricity cannot be stored, this transport involves several processes
conventional electric power plants
NUCLEAR POWER PLANTS
includes a nuclear fission reactor
Uranium is the main fuel used
FOSSIL FUEL THERMAL POWER PLANTS
water is heated in a boiler by the heat
generated from the combustion of a fossil fuel
Coal and gas are the main fuels
HYDROELECTRICAL POWER PLANTS
uses the potential energy provided by the
height of the stored water in a dam
energy produced by the movement of the water
ENVIRONMENTAL IMPACT
building and operating of an ejectrical power plant results in an
ecological change in that region
An environmental study must also assess both the economic and social
consequences in the area
ENVIRONMENTAL IMPACTS
Ex traction of natural resources
means the depletion
of resources
Fuel transport
Oil is transported by means of oil pipelines and oil tankers
Oil tankers can have accidents at sea that results in uncontrolled spills
Electricity generation
Large hydroelectric power plants require water reservoirs
Conventional thermal power plants can cause numerous problems
and environmental hazards
Final energy uses
The fuels we use in vehicles and heating systems emit pollutant gases and
particles
