Concept
How to speak in common, renewable energy are called energy sources or methods that exploit energy if measured by standards of the people is infinite. Infinite two means: Either the power exists to the extent that many can not become exhausted due to the use of man (eg solar energy) or self-renewable energy in a short time and continuous (eg biomass) in the process also took a long time in progress on Earth.
Sense of physics, energy is not renewable because that first brought the sun and are converted into forms of energy or materials with different energy. Depending on the situation where energy is used immediately or be temporarily reserve. The use of the term "renewable" manner of speaking often used to refer to the cycle of reproduction, which is short for humans to many (eg biogas compared to fossil energy).
In the sense of human time, the sun will provide a source of energy in a time almost endless. Sun also supplies power continuously for more progress in the election process took Earth's biosphere. The process can provide energy for people and also bring the so-called re-growth material. Flow of wind, water flowing and heat of the sun have been humans use in the past. Most important in an era of water power industry is looking at the use of technical aspects and the cost of ecological aspects.
In contrast to the use of this process is the exploitation of energy sources such as coal or oil, energy sources that are consumed today are created faster than many. By defining the meaning of existence "endless" the general nuclear reaction (fusion reaction), as can be done On the technical side and fission (fission) to the reactor recycle (Breeder reactor), the energy consumption or waste at uranium mining Thorium can be kept low, are sources of renewable energy, although they are often not included in the category this energy.
Solar energy is collected on the Earth's energy lines electromagnetic radiation comes from the sun to Earth. We will continue to receive the flow of energy until nuclear reactions in the sun out of fuel, about 5 billion years.
Can directly collect this energy through the photoelectric effect, transfer the photon energy of the sun into electricity, as in solar batteries. Energy of the photons can be absorbed to heat the object, that is converted into heat energy, average water use for the sun, or boiling water in thermal power of the solar tower, or shipping dynamic systems such as thermal solar air conditioner.
Energy of the photons can be absorbed and metabolized into energy in the chemical bonds of the optical chemical reactions.
A chemical reaction of natural photosynthesis is the process of photosynthesis. This process is believed to have used solar power reserves in fossil fuels are not renewable, but the industry of the 19th century has been to 21 advantage. It is also the process of providing energy for all biological activity of natural, animal traction and the wood burned, the source of renewable bioenergy tradition. In the future, this process can help create sources of renewable energy in biofuels, such as liquid fuel (biodiesel, fuel from vegetable oil), gas (bio-gas) or solid .
Solar energy is also absorbed by the Earth's hydrosphere and atmosphere to produce meteorological phenomena, which contains stored energy can be exploited. Earth, the energy of this model, nearly the same average water temperature of the engine first, metabolic heat absorbed from the photons of the sun, the kinetic energy of the flow of water, steam and air , and changing nature of chemistry and physics of these flows.
Potential of rainwater can be stored in dams and run the generator of hydroelectric works. Utilize a form of energy flowing rivers and streams before the birth of mortars hydroelectric water mill. Flow of the sea can also cause movement of the power plant generator uses the flow of the sea.
Flow of air, or wind, can generate electricity when the wind turns turbines. Before generator used wind born, windmill has been used to grind grain. Wind power is causing waves on the sea movement. Motion can be utilized in power plants using sea waves.
Ocean on Earth has a larger thermal conductivity and therefore air temperature changes more slowly when the air absorbs the heat of the sun. Hot air over the ocean at night and colder air during the day. Temperature difference can be exploited to run the engine thermal power plants use the heat of the sea.
When heat energy from photon absorption of the sun to evaporate sea water, a power that was stored in separate salt from salt water of the sea. Power plants using reaction freshwater - saltwater collection section energy when put fresh water of the river back to sea.
Derived from the heat of the Earth
Heat of the Earth, known as geothermal, thermal energy is that the Earth has been through nuclear reactions Am I in the heart. This heat to melt the soil rock the Earth, causing the displacement and the continental shelf born volcano. The nuclear reactions in the Earth will turn off and the temperature gradually Earth will cool slowly, faster than the life of the Sun.
Geothermal nonetheless still be a source of energy production medium scale industries, in areas such as:
