The Sun sends to our planet about 750000 trillion kWh per year, part of it is reflected by the clouds and the same land surface (land and sea), and another is absorbed by bare ground, by terrestrial and marine vegetation. Wind energy, i.e. energy transferred from the winds, is consequence of the warming of different surfaces of our planet, this heat is transferred to the air creating a pressure difference and causing displacement of air from place to another. It is estimated that nature generates wind energy on the Mainland area to a regime of 1670 billion kWh per year. The hydraulic power pack, with the resource water is part of the nature the occupying parts of the planet’s surface. The evaporation of the sea water, its fall to the surface by precipitation (rainfall) and returning to the sea through rivers or leaks, is called the water cycle. Hydraulic energy is one that possesses water due to its motion (kinetic energy) or its position relative to height (potential energy) differentials.

Currently, technology has focused on extracting the potential energy of water power. It is necessary to develop even more technology to extract energy from water currents. The energy of the biomass, in general biomass refers to all constituent substance of beings living or derived from them. In general, all matter of vegetable origin call you biomass and the energy which is obtained from them, is when she is devoured, burned or converted into fuels is known as biomass energy. So, since the microbes, bacteria, plants, trees, animals, vegetables, animal fat, manure, organic waste and even origin fuels oils fossil, they represent forms of matter obtained from biomass, which can be produced, cultivated or transformed in a number of ways to meet the needs of man. 2. Geothermal energy, comes from the extraordinary thermal activity that holds the nucleus of our planet, which reaches the surface in many parts, showing how phenomena and geological formations that allow the exhaust of a small part of the energy that comes from the center of our planet, but that is significant considering our demand for energy. Geothermal energy, is that underground (in the form of heat) energy, identified and quantified, is technically and economically exploitable to meet energy requirements corresponding to the activities carried out by man (heat and power).

An initial disadvantage is that it is not available in all places. 3. The hydrogen energy. This gas is a simple, abundant in nature and the universe, element of clean burning (not containing carbon); However, finding it is pure State is very rare, so it is necessary to remove it using various techniques to apply to water (H2O), but is also part of fossil fuels (petroleum, natural gas). In the case of these latter, it is necessary to remove cleanly the hydrogen. In case of water, you get hydrogen by electrolysis, which consists of the application of electricity to the separation of the components of water, you can also get it through heat (thermolysis), fermentation and even obtain the dissociation of water through the application of light (photolysis). Today, to obtain hydrogen cleanly. The most common form of employment of the hydrogen is in so-called fuel cells, which is not another thing that convert chemical energy into electricity, currently used as a source of energy in automobiles. The largest manufacturer of batteries is the Japan. A very important detail is that it they are developing studies and experimentation to obtain electric energy from glucose and fats, especially to cheapen the technology involved.
