Summary: To start this module it is necessary an introductive part about the use of wind energy to produce electricity. There are presented historical data of wind energy use, the evolution in time of wind turbines, basic constructive configurations of turbines with the principal elements components. There are presented the conditions for efficient exploitation and it is pointed out the importance of the development of electricity production using wind energy.

Principles concerning the use of wind energy Historical data of wind energy useAs already introduced in Module 1 of the course, wind can be defined as the movement of air masses from the Earth's atmosphere, generated by differences of pressure between two areas of the globe (baric gradient). These differences are determined by the uneven heating due to solar radiation and to Earth's rotation. When the air is heated, the warmer air rises faster because a volume of hot air is lighter than an equal volume of cold air. Hot air particles have a higher pressure than colder particles, therefore, it takes fewer particles to maintain the same air pressure. When warm air rises, cold air flows into the spaces that hot air leaves behind it, and the air that rushes to fill the gap is called wind. The wind presses on any object that lies in its path, and in the process, energy transfers occur to the object which was in the path of wind. This is how wind turbines produce energy.Wind is a clean energy source, free and inexhaustible. That is why, as explained in the introductory module of the course, wind power has been used by humans for thousands of years. For examp...

Once the technological possibilities offered by this technology are known, the main factors that determine the efficiency of photovoltaic systems such as radiation, inclination, shade, losses and efficiency will be dealt with.

Therefore, it does not contribute to climate change or global warming.The transformation of solar radiation into electrical energy is possible because of the photovoltaic effect. This phenomenon occurs when solar radiation photons impact on a semiconductor surface. If the photon hits the semiconductor surface with enough energy, it releases an electron that leaves enough space for the electrons to move and generate an electric current as a consequence. Photovoltaic solar energy usesAfter some years of technological development, photovoltaic solar energy applications have expanded into various fields:-Rural electrification: photovoltaic solar energy enables the electrification of buildings located at a significant distance from the electrical grid, or buildings which can not afford the high grid connection prices. These buildings have habitually been obtaining their energy needs from disesel/gas generators.-Electrification of boosters, maritime beacons, and road signposting: temporary low-power supplies. Their electrification through the electrical grid would involve an unreasonable cost.-Electri...
