Electricity consumption is the common form of energy intake, which makes use of electrical energy produced by various electrical sources. The most common electric energy sources are electricity produced through fossil fuels and hydroelectricity. Hydroelectricity produces power when flowing water is turned into steam and then directed to a turbine, generating electricity. The commonly used sources of electric current are gasoline and coal.
Heat production is another sector
that contributes significantly to electricity consumption in many countries across the world. This is mainly because vast quantities of fossil fuels are required to fuel the heat production industry. A large number of industry sectors manufacture heat-producing devices, with petroleum being the primary energy commodity used in the industry. With the rising prices of petroleum and the dwindling amounts of this non-renewable resource, there is a great possibility for the heat production sector to contract considerably in the coming decades. However, there is still an immense scope of energy production from renewable resources like geothermal, solar, and hydroelectric power sectors. This has led to increased awareness regarding this sector, leading to more innovations in the area.
Despite these facts, it is estimated that approximately 8%
of the total electricity consumption made in a year is generated from the non-renewable resources mentioned above. This is mainly because geothermal plants do not need to generate their energy, but only consume the heat that is emitted by the Earth itself. Geothermal plants can be positioned anywhere on the planet and are very friendly to the environment.
There are three major factors
which determines the level of the total residential electricity consumption in any country or region: the population of the country, the economy of the country, and its geographical location. It has been estimated that if the population of a country is less than 5 million, less than 0.5% of its energy is required from non-renewable sources like coal, petroleum, and gas. However, if the same population is more than five million, then about 50% of the electricity use is generated from these sources. The other areas in the world, which fall under this category include the island nations of the Pacific Ocean and the Middle East.
Another important aspect of the total electricity consumption
in a country or region is geography. A dense population center like New Delhi in India has high usage rates, whereas a smaller, peaceful center like Lagos in Nigeria has much lower consumption rates. The geographical distribution of the electricity among different users is also affected by the type of transmission lines that exist in a particular area. There are several types of electrical power transmission lines, which are available in the market, including the main electric transmission lines, which are used for the transportation of electricity across regions. There are also the so-called subsidiary electric lines, which are mainly used for the transmission of telephone and cable networks.
The electricity consumption in the residential sector
comes down considerably after the household appliances are switched off. However, when a person switches on the lights in his or her room, the household appliances like the television sets start functioning again. Therefore, most people have an automatic switch-on facility in their houses. It is estimated that around 2.2 billion kilowatt-hours per annum are consumed by the residential sector in various countries.
