This article focuses on the quantity of energy we consume — looking at total energy and electricity consumption; how countries compare when we look at this per person; and how energy consumption is changing over time.
Year-to-year change in primary energy consumption by source; Year-to-year change in primary energy consumption from fossil fuels vs. low-carbon energy; Year-to-year percentage change in primary energy consumption; Years of fossil fuel reserves left
Comprises commercially-traded fuels, including modern renewables used to generate electricity. Energy from all sources of non-fossil power generation is accounted for on an input-equivalent basis.
By 2025, Asia is projected to account for half of the world''s electricity consumption, with one-third of global electricity to be consumed in China. [1] This list of countries by electric energy consumption is mostly based on the Energy Information Administration. [2]
Electricity consumption grew by 2.6% in 2023, returning to its average growth rate (around 2.7% per year). It surged in the BRICS (+6%), especially in China (+6.9% to reaching one-third of global electricity consumption), in India (+6.7%), and in Brazil (+3.2%).

Electric energy is most often measured either in joules (J), or in watt hours (W·h).[4]
Electric and electronic devices consume electric energy to generate desired output (light, heat, motion, etc.). During operation, some part of the energy is lost depending on the electrical efficiency.[5]
Electricity has been generated in power stations since 1882.[6] The invention of the steam turbine in 1884 to drive the electric generator led to an increase in worldwide electricity consumption.[7]
In 2022, the total worldwide electricity production was nearly 29,000 TWh.[8] Total primary energy is converted into numerous forms, including, but not limited to, electricity, heat and motion.[9] Some primary energy is lost during the conversion to electricity, as seen in the United States, where a little more than 60% was lost in 2022.[9]
A sensitivity analysis on an adaptive neuro-fuzzy network model for electric demand estimation shows that employment is the most critical factor influencing electrical consumption.[11] The study used six parameters as input data, employment, GDP, dwelling, population, heating degree day and cooling degree day, with electricity demand as output variable.[11]
The table lists 45 electricity-consuming countries, which used about 22,000 TWh. These countries comprise about 90% of the final consumption of 190+ countries. The final consumption to generate this electricity is provided for every country. The data is from 2022.[8][12]
The table lists 30 countries, which represent about 76% of the world population, 84% of the world GDP, and 85% of the world electricity generation.[8][12][14][15] Productivity per electricity generation (concept similar to energy intensity) can be measured by dividing GDP over the electricity generated. The data is from 2019.[8][12][14][15]
The table below lists the 15 countries with the highest final electricity consumption, which comprised more than 70% of the global consumption in 2022.[8]
Looking forward, increasing energy efficiency will result in less electricity needed for a given demand in power, but demand will increase strongly on the account of:[20]
The World Energy Council[23] sees world electricity consumption increasing to more than 40,000 TWh/a in 2040. The fossil part of generation depends on energy policy. It can stay around 70% in the so-called Jazz scenario where countries rather independently "improvise" but it can also decrease to around 40% in the Symphony scenario if countries work "orchestrated" for more climate friendly policy. Carbon dioxide emissions, 32 Gt/a in 2012, will increase to 46 Gt/a in Jazz but decrease to 26 Gt/a in Symphony. Accordingly, until 2040 the renewable part of generation will stay at about 20% in Jazz but increase to about 45% in Symphony.
An EU survey conducted on climate and energy consumption in 2022 found that 63% of people in the European Union want energy costs to be dependent on use, with the greatest consumers paying more. This is compared to 83% in China, 63% in the UK and 57% in the US.[24][25] 24% of Americans surveyed believing that people and businesses should do more to cut their own usage (compared to 20% in the UK, 19% in the EU, and 17% in China).[26][27]
Nearly half of those polled in the European Union (47%) and the United Kingdom (45%) want their government to focus on the development of renewable energies. This is compared to 37% in both the United States and China when asked to list their priorities on energy.[26][28][29]
