Energy - Coggle Diagram
Energy
Energy sources
By availability in nature and capacity for regeneration
Renewable
Abundant and inexhaustible
Solar power
Non-renewable
Can be not abundant and don´t regenerate
Petroleum
By origin
Primary
Directly from nature
Coal, natural gas, etc
Secondary
Resulting from transformation of primary sources
Electricity, petroleum derivates, etc
By use in each country
Conventional
Commonly used in industrialised countries
Fossil fuels
Non-conventional
Alternative energy sources
Solar and wind power
By enviromental impact
Clean or non-polluting
Low enviromental impact
Wind power
Pollutants
Negative effects on the enviroment
Coal
Electricity
It can be easily transformed and transported long distances without wasting so much energy
Electricity power plants
Conventional electricity power plants
Fossil fuel thermal power plants
Coal or natural gas is used to heat water and produce the steam needed to move the turbine
Hydroelectric power plants
It uses the potential energy of the water stored in a dam coverting it into kinetic energy that moves the blades of a turbine.
Nuclear power plants
It has a nuclear fission reactor that produces steam to move the turbine. Uranium is used as fuel
Non-conventional electricity power plants
Geothrmal power plants
It uses the heat founded in deep levels of Earth
Biomass thermal energy
It uses agricultural waste to produce heat that produces steam
Solar power plants
Photovoltaic power plant
Solar radiation is transformed into electricity directly by photovoltaic panels
Phototermal power plant
It uses the heat of sun to produce steam that moves a turbine
Ocean power plants
It uses the mechanical energy of the waves and the ties
Wind power plants
It uses the kinetic energy of wind to move the blades of a turbine
How do they...
Produce electricity?
Turbine
Converts mechanical energy into the rotating movement of a shaft
Alternator
Rotor
Is conected to the turbine shaft, it moves
Stator
It doesn't move, electricity is pruduced on it's coils
Transport electricity
By high voltage cables attached to towers
