Thermal energy

Image of the Sun taken through x-ray.
The energy released as heat thermal energy is called. Can be obtained from nature or the Sun through an exothermic reaction, such as combustion of a fuel; by nuclear reaction of fission or fusion; using electrical energy Joule effect or thermoelectric effect; or by friction, as other processes mechanical or chemical residue. It is alsopossible to harness energy of nature found in form of thermal, photovoltaic solar energy or geothermal energy.
Thermal energy can be transformed using a heat engine, either in electric power, a thermoelectric power station; or working mechanic, as a motor car, plane or boat.
Thermal energy involves an environmental impact. Combustion releases carbon dioxide (CO 2) and pollutant emissions.Current nuclear energy technology gives rise to radioactive waste must be controlled. Use of field-generating power plants and risks of pollution accidents in the use of the materials involved, as the spills of oil and petrochemical products must also be taken into account.

Radiant energy

Light (a form of radiant energy).
Radiant energy is the energy that possess electromagnetic waves [] asthe visible light, radio waves, ultraviolet (UV), infrared (IR), etc. The main feature of this energy is that it propagates in vacuum material without any. Airs on units called photons.
CHEMICAL energy: It's produced by chemical reactions which emit heat or who by his violence can develop some work or movement. Foods are an example of chemical energy to be processed by the body heat (calories)offering us or are sources of natural energy (proteins and vitamins). Being burnt fuels produce violent chemical reactions that produce work or movement
Electric power

Consumption of electricity by country in million kWh.
It is called electrical energy in the form of energy resulting from the existence of a potential difference between two points, allowing you to establish an electriccurrent between them - when placed them in contact by means of an electrical conductor - to get work. Electrical energy can be transformed in many other forms of energy, such as the light or light, mechanical energy and heat.
Its use is one of the bases of the technology used by human beings today.
Electrical energy manifests itself as power, i.e. as movement negative electrical charge orelectrons, in a metallic conductor cable as a consequence of the difference of potential it a generator has implemented at their ends.
Every time that a switch is operated, closes an electrical circuit and is generated the movement of electrons through the conductor cable. Moving loads are part of atoms – you want to use, using the corresponding transformations; for example, when the electricity reachesan enceradora, becomes mechanical, caloric energy and in some cases luminous, thanks to the electric motor and various mechanical parts of the apparatus.
Nuclear energy

Susquehanna nuclear power plant, with two boiling water reactors (BWRS). Cooling is performed in closed by two cooling towers that emit steam circuit.
Nuclear energy is the energy released spontaneous or artificially innuclear reactions. However, this term covers another meaning, use this energy for other purposes such as, e.g., electric power, thermal and mechanical nuclear reactions and their application, either military or peaceful purposes. [1] Thus, it is common to refer to nuclear energy not only as the result of a reaction, but as a broader concept that includes knowledge and techniques that enable theuse of this energy of the human being.
Geothermal energy

Plant of geothermal energy in the Philippines.
Geothermal energy is the energy that can be obtained through the use of heat from the interior of the Earth. The heat of the interior of the Earth due to several factors, among which fit to highlight the geothermal gradient, the heat caused, etc. Geothermal comes from the Greek geo,...
