Energy Statistics Pocketbook Summary (2022)

Core Content

This document provides an overview of global energy statistics, focusing on total energy supply, primary energy production, and electricity generation from 1990 to 2019. It highlights key trends, regional contributions, and the role of different energy sources in meeting global demand.

Main Points

1. Total Energy Supply (TES)

• World TES in 2019: 601.7 EJ, representing a 68.2% increase from 1990.
• Asia was the main driver of global growth, contributing 83.6% of the world's increase in TES.
• China alone accounted for over a fifth of the world's TES in 2019, with a 4.5-fold increase.
• Europe's share dropped from 35.3% in 1990 to 17.6% in 2019, with an absolute decline of 20.1 EJ.
• United States saw a 7.1 percentage point decrease in its share of TES but experienced an absolute increase of 12.2 EJ.
• International bunkers increased from 8.7 EJ in 1992 to 17.1 EJ in 2019, nearly doubling.

2. Energy Intensity

• World energy intensity in 2019: 4.6 GJ per thousand international dollars.
• Top energy-intensity countries include Trinidad and Tobago (19.9), Bahrain (4.5), and Brunei Darussalam (3.9).

3. Primary Energy Production

• World primary energy production in 2019: 613 EJ, a 2.0% increase from 2018 and a 69.6% increase since 1990.
• Oil, coal, and natural gas together accounted for 82.0% of total primary energy production in 2019, with a minimal change since 1990.
• Top coal producers in 2019:
  • China: 80.0 EJ (80% of global coal production)
  • Indonesia: 15.1 EJ
  • United States: 14.5 EJ
  • Russian Federation: 10.6 EJ
• Top oil producers in 2019:
  • United States: 31.8 EJ
  • Russian Federation: 23.8 EJ
  • China: 8.0 EJ
  • Saudi Arabia: 22.7 EJ
• Top natural gas producers in 2019:
  • United States: 33.5 EJ
  • Russian Federation: 26.4 EJ
  • China: 7.0 EJ
  • Iran: 8.2 EJ

4. Energy Supply by Region and Source

• Coal was the largest contributor to global energy supply in 2019 (27.4%), followed by oil (30.9%) and natural gas (23.8%).
• Biofuels and waste accounted for 8.7%, nuclear for 4.9%, and electricity and heat for 4.6%.
• Asia (excluding China) had the highest growth in energy supply from 1990 to 2019, increasing from 63.2 EJ to 160.8 EJ.
• China increased its energy supply from 30.4 EJ in 1990 to 136.6 EJ in 2019.
• Europe decreased its share from 35.3% in 1990 to 17.6% in 2019.

5. Electricity Generation

• World electricity generation in 2019: 26,982.7 PWh, a 125% increase since 1990.
• Coal and natural gas saw the largest absolute growth in electricity generation, with coal increasing by 5,447 TWh and natural gas by 4,626 TWh.
• Solar, wind and other sources experienced the fastest growth, increasing by 3,572% or 2,197 TWh.
• Nonrenewable sources (coal, oil, natural gas, nuclear) accounted for 73.6% of global electricity generation in 2019, while renewables made up 35.8%.
• China was the largest electricity generator in 2019, with 7,503.5 PWh, followed by United States (4,391.8 PWh), Europe (4,849.5 PWh), and Asia (excluding China) (6,734.9 PWh).
• Africa and Latin America and the Caribbean saw significant growth in electricity generation over the period.

Key Information

• The data are sourced from the United Nations Energy Statistics Database and are based on annual publications such as the Energy Statistics Yearbook, Energy Balances, and Electricity Profiles.
• The report emphasizes the role of energy in achieving the 2030 Agenda for Sustainable Development and the Paris Agreement on climate change.
• It highlights the importance of energy statistics in policy formulation and progress measurement.
• The United States and China are the leading energy producers, with China being the largest contributor to the increase in TES.
• Renewable energy capacity additions have grown significantly, reaching 2,647 GW in 2019 and contributing 35.8% of total electricity generation.
• Energy intensity varies widely across countries, with some regions (e.g., Trinidad and Tobago) showing much higher values than others (e.g., World average at 4.6 GJ per thousand international dollars).

Visualizations and Data Sources

• The report includes charts and tables to illustrate trends and distributions.
• All data is available in the Energy Statistics Yearbook, Energy Balances, and Electricity Profiles.
