energy and its transformation

non-conventional electric power plants

environmental impact

conventional electric power plants

energy sources

natural resources from which we obtain different forms of energy that can be transformed for a specific use

household

the operating of electricl applicances, heating systems, hot water systems, heat for cooking and for meats of transport

industrial

the operating of factories and companies, construction, agriculture and so on.

classification

by availability in nature and capacity for renegeration

by origin

by use in each country

by environmental impact

electricity

is the most widely used form of energy in indutralised societies

it can be easy transformed

it can be transported long distances

electric power plants

imagen

imagen

are facilities where primary or secondary energy is transformed into electricity

How an electric power plant works

the turbine converts mechanical energy into the rotating movement of a shaft

an alternator has fixed part and a moving part connected to the turbine shaft

transport and distribution of electrical energy

transporting it by high voltage cables

decreasing the voltage

increasing the voltage to prevent significant energy loss

distribution

fossil fuel thermal

hydroelectric

nuclear

This type of plant tm.ludes a nuclear fission reactor that produces the pressurised steam needed to move the turbine rotor

water is heated in a boiler by the heat generated from the combustion of a fossil fuel (natural gas or coal)

combined cycle power plant

electricty ts generated as a result of two combined cycles. During the first cycle,a gas turbine is used that includes a compressor.
Air is mixed with the gas and is burnt, which generates electricity.
The combustion gases are transformed to a boiler

This type uses the potential energy provided by the height of the stored water in a dam, converting it into kinetic energy.

gravity-driven hydraulic power plants

pump-driven hydraulic power plants

Geothermal

Biomass

solar power plants

wind power plants and wind farms

ocean

These power plants use the kinetic energy of the wind to move the blades of a rotor at the top of a tower (wind turbine). Wind farms are a clean form of generating electricity.

photo- termal

photovoltaic

In this type of power plant, they use heat generated by solar radiation.

In these power plants, solar radiation is transformed directly into electricity by panels of photovoltaic cells

ºGeotermal energy may be used directly-for hot water and heating - and indirectly- the heat generates steam

Biomass
consists of all organic compounds that are produced throught natural processes. Biomass is subjected into different physical and chemical processes in order to produce fuel.

They use the energy from the seas and oceans
