The energy produced by electrical charges can manifest itself in four domains: physical, luminous, mechanical, and thermal.<\/strong><\/p>\n\n\n\n While electricity is abstract or \u2018invisible\u2019 in most of its manifestations, such as in the human nervous system, it is sometimes possible to \u2018see\u2019 it, such as lightning when a severe thunderstorm develops.<\/p>\n\n\n\n Primary energies<\/strong> are those obtained directly from nature: solar, hydraulic, wind, geothermal, biomass, oil, natural gas, or coal.<\/p>\n\n\n\n Secondary energies <\/strong>come from the transformation of primary energy for direct consumption or for other uses: petrol, electricity, diesel, fuel oil, etc.<\/p>\n\n\n\n Electricity is produced by electricity systems<\/strong> that guarantee its availability.<\/p>\n\n\n\n An electricity system is the set of elements that operate in a coordinated manner in a given territory to satisfy the consumers' demand for electricity.<\/p>\n\n\n\n Electricity systems can be classified as follows:<\/p>\n\n\n\n Electricity is an indispensable source of energy<\/strong>. In every household, there are all kinds of appliances and domestic appliances that run on electricity, as well as the lighting system.<\/p>\n\n\n\n In industry, almost half of the energy consumed is electrical. Electricity is used both as a driving source for the electric motors of the machines and appliances in each sector, and to heat the contents of tanks, reservoirs, and boilers. As in the domestic sector, electricity is also the main lighting source,<\/strong> providing heating and cooling for air-conditioning equipment.<\/p>\n\n\n\n The tram, metro,<\/span> or train is the means of electric transport <\/strong>par excellence. Currently, electric vehicles are being designed mainly for urban use, as well as so-called \u2018hybrid\u2019 vehicles in which the electric motor is combined with an internal combustion engine, thus enjoying the advantages of both energy sources. The battery can be recharged by simply plugging it into an electrical socket.<\/p>\n","protected":false},"excerpt":{"rendered":" Electricity is an indispensable source of energy.
