The educational resource shows information about the concept windy energy and its advantages and its disadvantages.

A picture shows some transformations of energy. The energy from the sun passes to plants, to oil, to coal, to animals and to human beings; they take advantage of it by using the energy from oil, animals, coal, etc.

The educational resource shows information about the concept tidal energy and its advantages and its disadvantages.

The educational resource shows information about the concept of thermal energy: thermal energy is due to the movement of the particles which make up matter.

The educational resource shows information about the solar energy and its advantages and its disadvantages.

Renewable energy sources are those which after being used can be regenerated naturally or artificially. The following pictures are graphic examples rof enewable energy sources.

Concepto del rendimiento de una máquina. El ODE muestra la definición del rendimiento de una máquina a través de una animación Flash.

Concepto de el Segundo Principio de la Termodinámica. El ODE muestra una escena se examina qué forma tiene el segundo principio para máquinas que funcionan con energía de origen térmico.

Principio que refleja la conservación de la energía en el contexto de la termodinámica.

Oil is the product of the decomposition of the remains of microscopic living organisms which millions of years ago inhabited the seas, lakes and river estuaries. Oil today has a multitude of applications. This is why is it essential not to waste it simply as fuel. The following visual shows how it is formed and how it is used.

Nuclear energy is the energy stored in the nuclei of atoms and it is released in the nuclear reactions of fission and fusion.

The educational resource shows information about a nuclear power station, how it works and its advantages and its disadvantages.

The educational resource shows information about the concept of natural gas: Natural gas has a similar origin to oil and is usually found forming a layer or deposit on the top of oil fields.

El ODE plantea la cuestión ¿es posible que un sistema se mueva indefinidamente sin que se le suministre energía? Para ello se muestra una animación donde un sistema formado por dos bolas que colisionan. Se pueden modificar el ángulo de partida de una de las bolas y si las condiciones del experimento son ideales o no.

En el ODE se muestra el funcionamiento de un motor real de combustión, donde la energía se extrae quemando algún combustible. Se representa un gráfico presión/volumen donde se puede observar las compresiones y expansiones del citado motor.

Mechanical energy is what is produced by mechanical type forces, like elastic and gravitational forces.The following three pictures show situations involving mechanical energy.

The educational resource shows an interactive animation about the internal combustion engine: in real combustion engines, the energy is extracted from the combustion of some type of fuel, which has been injected into a cylinder, finely pulverised and mixed with oxygen. Then the combustible mixture is compressed and ignited to explode. That is why these engines are known as combustion engines.

Concepto de la energía en los diferentes sistemas materiales. En este ODE se expone la idea de que la energía que posee un cuerpo es la capacidad que tiene ese cuerpo para producir cambios en su alrededor, bien realizando trabajo sobre otros cuerpos o transfiriendo calor.

Concepto de combustibles fósiles. La actividad ofrece la definición de combustibles fósiles y presenta tres animaciones sobre ellos: petróleo, carbón y gas natural.

Concepto de energía solar. El ODE ofrece información respecto a qué es la energía solar, cómo se aprovecha y qué ventajas e inconvenientes ofrece. Se acompaña esta información de una imagen de paneles fotovoltaicos.
