Electric Energy Consumption Measurement and Efficiency
– Electric energy is measured in joules (J) or watt hours (W·h).
– 1 W·s is equal to 1 J.
– 1 W·h is equal to 3,600 W·s or 3,600 J.
– 1 kWh is equal to 3,600 kWs, 1,000 Wh, 3.6 million W·s, or 3.6 million J.
– Electric and electronic devices consume electric energy to generate output, but some energy is lost due to electrical efficiency.
Worldwide Electricity Consumption
– In 2022, the total worldwide electricity production was nearly 29,000 TWh.
– Electricity accounted for over 20% of worldwide final energy consumption in 2022.
– The industrial sector consumed the largest share of electricity (42.2%), followed by residential (26.8%), commercial and public services (21.1%), transport (1.8%), and other sectors (8.1%).
– In recent decades, consumption in the residential and commercial sectors has increased, while industrial consumption has declined.
– The electric vehicle market has contributed to an increase in electricity consumption in the transport sector.
Consumption per Capita
– In Western Europe, electricity consumption per capita ranges between 4 and 8 MWh/year.
– Developed countries like Scandinavia, the United States, Canada, Taiwan, South Korea, Australia, Japan, and the United Kingdom have higher per capita consumption.
– Developing countries generally have lower per capita consumption.
– The world average per capita consumption was approximately 3 MWh/year in 2022.
– Countries with very low consumption levels often have a significant portion of their population not connected to the electricity grid.
Electricity Generation and GDP
– Productivity per electricity generation can be measured by dividing GDP over the electricity generated.
– In 2019, India had a GDP of $2,871 per electricity generated, while the USA had $21,433.
– Indonesia had a GDP of $1,119 per electricity generated, while Brazil had $1,878.
– Nigeria had a GDP of $448 per electricity generated, while Russia had $1,687.
– Japan had a GDP of $5,149 per electricity generated, while Mexico had $1,269.
Electricity Consumption by Sector
– The table lists the top 15 countries with the highest final electricity consumption, accounting for more than 70% of global consumption in 2022.
– The industrial sector consumes the largest share of electricity in most countries.
– The residential and commercial sectors have witnessed growth in consumption.
– The transport sector has seen an increase in consumption due to the electric vehicle market.
– The distribution of electricity consumption varies among countries and regions. Source: https://en.wikipedia.org/wiki/Electric_energy_consumption
Electric energy consumption is energy consumption in the form of electrical energy. About a fifth of global energy is consumed as electricity: for residential, industrial, commercial, transportation and other purposes. Quickly increasing this share by further electrification is extremely important to limit climate change, because most other energy is consumed by burning fossil fuels thus emitting greenhouse gases which trap heat.
The global electricity consumption in 2022 was 24,398 terawatt-hour (TWh), almost exactly three times the amount of consumption in 1981 (8,132 TWh). China, the United States, India and Japan accounted for more than half of the global share of electricity consumption.
