2025: Which power sources are most common in each country. Card
Traditional fossil fuels, including natural gas, oil and coal, continue to be actively used around the world. This is evidenced by Dewesoft data, which TAdviser got acquainted with in early October 2025.
Dewesoft researchers analyzed information on electricity generation in countries around the world, identifying the most common energy sources for each region. As noted, gas is the most common source in countries such as, Russia,, Belarus,, USA,,, and Italy Israel. In Japan, Netherlands,, Singapore ,, Britain China South and Australia India Indonesia Malaysia most To Africa South Korea in demand coal. In many countries, oil is called the most common type of fuel: this, in particular,,,, etc. Palestine Somalia Syria Yemen Nuclear power prevails in,, and a number of other Finland France Belgium states.
Many countries are actively developing renewable energy sources, including solar, wind and hydroelectric power plants, the study said. Hydropower is the most widely used renewable resource per capita in the world - it is actively used in the following countries:
Wind power is most developed in Denmark, Sweden and Ireland, while solar power is most used by Puerto Rico, Australia and Japan. Other renewable resources include fuels such as biomass (organic materials such as wood, biogas, ethanol and biodiesel) and geothermal energy. They are popular in both developing countries and states seeking to reduce carbon dioxide emissions from traditional fossil fuels.[1]

Global energy consumption of data centers used for artificial intelligence tripled in a year
The energy consumption of data centers used for artificial intelligence on a global scale at the end of 2023 reached 195 TWh, which is almost three times more than a year earlier. This is evidenced by data from Gartner, which was released in November 2024. Read more here.
Global electricity consumption growth by 2% to 620 exajoules
In 2023, the volume of primary energy consumption on a global scale reached a record value of approximately 620 exajoules (EJ). This is 2% more compared to the previous year. Such data are given in the report of the Energy Institute organization, published on June 20, 2024.
It is noted that the world consumption of fossil fuels in 2023 rose on an annualized basis by 1.5%, amounting to 505 EJ, which is the maximum value in the entire history of statistics collection. In particular, coal consumption increased by 1.6% year-on-year, oil - by 2% (for the first time exceeding 100 million barrels per day). At the same time, gas consumption on an annualized basis has practically not changed.
Electricity production from renewable sources, excluding hydropower, rose 13% in 2023 - to a record high of 4,748 TVt·ch. This growth was almost entirely due to wind and solar energy. In general, the share of renewable sources excluding hydropower in the total energy balance was 8% against 7.5% in 2022. Taking into account hydropower, the indicator reached about 15%.
Gas demand in Europe fell 7% in 2023 after declining 13% in 2022, the report said. Russia's share in gas imports to the EU amounted to 15% against approximately 45% in 2021. In Europe, the share of fossil fuels has fallen to below 70% of total primary energy consumption - the first time since the Industrial Revolution: driven by reduced demand and rising renewable energy rates. The share of fossil fuels in the United States fell to 80%.
In India, fossil fuel consumption rose 8% to 89% of total consumption in 2023. For the first time in this country, more coal was used than in Europe and North America combined. And in Africa, primary energy consumption fell by 0.5% in 2023[2]
Growth in electricity generation at coal-fired thermal power plants by 1.6% to 10.61 trillion kVt·ch
At the end of 2023, electricity generation at coal-fired thermal power plants (TPPs) on a global scale reached 10.61 trillion kVt·ch. For comparison, a year earlier, the figure was 10.44 trillion kVt·ch. Thus, on an annualized basis, growth was recorded at 1.6%, as stated in the report of the International Energy Agency (IEA), published on January 24, 2024.
In July 2023, the IEA predicted a decrease in coal TPP production at the end of this year by 0.4% (to 10.41 trillion kVt·ch), and in 2024 - by 1% (to 10.31 trillion kVt·ch). However, instead, in 2023, an increase in production was demonstrated, which is associated with high gas prices in the formed geopolitical situation. The report says that in 2023, electricity generation from gas amounted to 6.64 trillion kVt·ch against 6.61 trillion kVt·ch in 2022. That equates to a 0.5% year-on-year increase.
In general, global electricity demand rose 2.2% in 2023 to kVt·ch 27.68 trillion. It is noted that in China, India and many countries of Southeast Asia there was a steady increase in electricity demand. At the same time, consumption in advanced economies has significantly decreased due to the unfavorable macroeconomic situation and high inflation: these factors have led to a decrease in the workload of industrial enterprises.
The authors of the study note that by the beginning of 2025, renewable energy sources will provide more than one third of the total electricity production in the world, overtaking coal-fired TPPs. The share of "green" energy sources in total production will grow from 30% in 2023 to 37% in 2026. Moreover, according to experts, this growth will largely be ensured by the emergence of increasingly cheaper solar photovoltaic systems.[3]
2022 Data centers account for 1-1.5% of global electricity consumption
In 2022, data centers accounted for about 1-1.5% of global electricity consumption. This is evidenced by data from the International Energy Agency (IEA), which was released in September 2024. Read more here.
