SOLAR ENERGY

Spain is a country that receives a large amount of solar radiation, which allows solar energy to have great importance and future in Spain.It is not a resource as exploited as it should be.

WIND POWER

This source of energy is one in which Spain has been a pioneer worldwide, producing in 2007 20% of the world's wind power.This energy does not pollute, but it has contrasts that it is intermittent (it depends on the wind) and that it can contribute to favor erosion.

BIOMASS

Is that which is obtained from organic compounds by natural processes. With the term biomass refers to solar energy, converted into organic matter by vegetation, which can be recovered by direct combustion or transforming that matter into other fuels, such as alcohol, methanol or oil.

HYDRAULIC ENERGY

Is the one produced by water retained in reservoirs or swamps at high altitude (which has gravitational potential energy). If at any given moment it is allowed to fall to a lower level, this energy is converted into kinetic energy and, later, into electrical energy in the hydroelectric power station.

ENERGY OF THE SEA

One of the most unknown renewable energies is that hidden in the sea. Today, ocean waters represent a great source of energy almost untapped but, in the coming years, could become one of the main energy sources in some parts of the planet.

Geothermal

Geothermal energy is a source of renewable energy that takes advantage of the heat that exists in the subsoil of our planet. Its main applications are in our daily lives: to climatize and obtain sanitary hot water in an ecological way both in large buildings (offices, factories, hospitals, etc.) and in homes

Non-renewable

The oilThe natural gas

CharcoalThe nuclear energy

Charcoal

Coal was the main source of energy in the first and second industrial revolution, but was replaced by oil in the late 50's.

NUCLEAR ENERGY

The main problems posed by nuclear energy are the production of radioactive waste and the risk of leaks.Its use increased in Spain from 1975, but it fell again in 1984 due to the nuclear moratorium before the risks that its use can pose.

THE OIL

In Spain, the main energy source in Spain, with 48.5%. There are few deposits.

NATURAL GAS

High calorific power.Economic price.Contaminates less than coal and oil (although it is polluting).Greater diversification in its obtaining, that is, its location is more diverse than oil, for example.

Where energy you consume come from?

The energy consumed in our town comes from the thermal power station of Castellón.

What is an electric power plant?

An electric plant is a machine that moves a generator of electricity through an internal combustion engine.

How is produced the energy you consume?

The electrical energy that we consume at every moment in our house, in the institute, etc. has been generated in different ways: taking advantage of the energy of the falling water (hydraulic), in thermoelectric plants (coal or gas combined cycle), in wind farms, solar farms, or nuclear power plants that fissure Uranium atoms.

WIND POWER

This source of energy is one in which Spain has been a pioneer worldwide, producing in 2007 20% of the world's wind power.This energy does not pollute, but it has contrasts that it is intermittent (it depends on the wind) and that it can contribute to favor erosion.
