Electric Energy Consumption
Electric energy consumption is the form of energy consumption that uses electrical energy. Electric energy consumption is the actual energy demand made on existing electricity supply for transportation, residential, industrial, commercial, and other miscellaneous purposes. Global electricity consumption in 2019 was 22,848 terawatt-hour (TWh), about 135% more than the amount of consumption in 1990 (9,702 TWh). China, United States, and India accounted for over 50% of the global share of electricity consumption. Overview Electric energy is most often measured either in joules (J), or in watt hours (W·h). : 1 W·s = 1 J : 1 W·h = 3600 W·s = 3600 J Electric and electronic devices consume electric energy to generate desired output (i.e., light, heat, motion, etc.). During operation, some part of the energy is lost depending on the electrical efficiency. Electricity has been generated in power stations since 1882. The invention of the steam turbine in 1884 to drive the electr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy Consumption
Energy consumption is the amount of energy used. Biology In the body, energy consumption is part of energy homeostasis. It derived from food energy. Energy consumption in the body is a product of the basal metabolic rate and the physical activity level. The physical activity level are defined for a non-pregnant, non- lactating adult as that person's total energy expenditure (TEE) in a 24-hour period, divided by his or her basal metabolic rate (BMR): :\text=\frac Demographics Topics related to energy consumption in a demographic sense are: * World energy supply and consumption * Domestic energy consumption * Electric energy consumption Effects of energy consumption * Environmental impact of the energy industry ** Global warming * White's law Reduction of energy consumption * Energy conservation, the practice of decreasing the quantity of energy used * Efficient energy use See also * Energy efficiency * Energy efficiency in transportation * Electricity generation * E ...

Renewable Energy
Renewable energy is energy that is collected from renewable resources that are naturally replenished on a human timescale. It includes sources such as sunlight, wind, the movement of water, and geothermal heat. Although most renewable energy sources are sustainable, some are not. For example, some biomass sources are considered unsustainable at current rates of exploitation. Renewable energy often provides energy for electricity generation to a grid, air and water heating/ cooling, and stand-alone power systems. Renewable energy technology projects are typically large-scale, but they are also suited to rural and remote areas and developing countries, where energy is often crucial in human development. Renewable energy is often deployed together with further electrification, which has several benefits: electricity can move heat or objects efficiently, and is clean at the point of consumption. In addition, electrification with renewable energy is more efficient and therefo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Energy Supply And Consumption
World energy supply and consumption is global production and preparation of fuel, generation of electricity, energy transport, and energy consumption. It is a basic part of economic activity. It includes heat, but not energy from food. This article provides a brief description of energy supply and consumption, using statistics summarized in tables, of the countries and regions that produce and consume most. Energy production is 80% fossil. Half of that is produced by China, the United States and the Arab states of the Persian Gulf. The Gulf States and Russia export most of their production, largely to the European Union and China, where not enough energy is produced to satisfy demand. Energy production is increasing 1 to 2% per year, except for solar and wind energy which averaged 20% per year in the 2010s. Produced energy, for instance crude oil, is processed to make it suitable for consumption by end users. The supply chain between production and final consumption involves ...

List Of Countries By Renewable Electricity Production
This article is a list of countries and territories by electricity generation from renewable sources every year. Note that most countries import and/or export electricity, so the percentage figure do not reflect the percentage of consumption that is renewable based. Based on REN21's 2020 report, renewables contributed 19.2% to humans' global energy consumption and 23.7% to their generation of electricity in 2014 and 2015, respectively. This energy consumption is divided as 8.9% coming from traditional biomass, 4.2% as heat energy (modern biomass, geothermal and solar heat), 3.9% hydro electricity and 2.2% is electricity from wind, solar, geothermal, and biomass. Worldwide investments in renewable technologies amounted to more than US$332 billion in 2018. Globally, there are approximately 7.7 million jobs associated with the renewable energy industries, with solar photovoltaics being the largest renewable employer.IRENARenewable energy and jobs ''Annual review 2015'', IRENA.Retr ...

List Of Countries By Electricity Consumption
This list of countries by electric energy consumption is mostly based on the Energy Information Administration. Several non-sovereign entities are also included for information purposes, with their parent state noted. The per capita data for many countries may be slightly inaccurate as population data may not be for the same year as the consumption data. Population data were obtained mainly from the World Bank in 2019 with some exceptions, in which case they were obtained from the Wikipedia pages for the corresponding countries/territories. Average power per capita was calculated according to the formula:It is interesting to compare the average electric power consumed per capita with the person's basal metabolic rate (about 65 watts), the average power obtained by a human body at rest from the food metabolism. :Electric energy per capita watt-hour.html"_;"title="in_watt-hour">in_watt-hour_=_Total_population_electricity_consumption_[in_Watt-hour#Explanation.html" "title="watt-h ...

List Of Countries By Carbon Dioxide Emissions
This is a list of sovereign states and territories by carbon dioxide emissions due to certain forms of human activity, based on thEDGAR databasecreated by European Commission and Netherlands Environmental Assessment Agency released in 2018. The following table lists the 1990, 2005 and 2017 annual emissions estimates (in Megatonnes of per year) along with a list of calculated emissions per km2 (in tonnes of per year) and emissions per capita (in tonnes of per year). I The data only consider carbon dioxide emissions from the burning of fossil fuels and cement manufacture, but not emissions from land use, land-use change and forestry. Emissions from international shipping or bunker fuels are also not included in national figures, which can make a large difference for small countries with important ports. When carbon dioxide emissions from land-use change are factored in, the majority of carbon emissions since 1905 occurred in Asia, Central and Southern America, reflecti ...

Electricity Retailing
Electricity retailing is the final sale of electricity from generation to the end-use consumer. This is the fourth major step in the electricity delivery process, which also includes generation, transmission and distribution. Beginnings Electricity retailing began at the end of the 19th century when the bodies which generated electricity for their own use made supply available to third parties. In the beginning, electricity was primarily used for street lighting and trams. The public could buy once large scale electric companies had been started. The provision of these services was generally the responsibility of electric companies or municipal authorities who either set up their own departments or contracted the services from private entrepreneurs. Residential, commercial and industrial use of electricity was confined, initially, to lighting but this changed dramatically with the development of electric motors, heaters and communication devices.
