Summary of ENERDATA Global Energy Trends 2023 Report

Key Global Trends in 2021-2022

The report analyzes 2021 and 2022 data benchmarks for G20 countries, showing a return to pre-2020 economic growth trends after the pandemic. Energy consumption grew at historic rates, driven by robust economic recovery, while CO2 emissions rose to record levels, exceeding 2019 levels. Economic growth was diverse, with the EU and specific nations like Brazil and India showing strong gains, while China and Russia faced slowdowns due to policies and sanctions. Despite efforts to decouple economic growth from energy consumption, the linkage remained strong, and energy intensity improvements were insufficient.

Energy Consumption and Emissions

Global energy consumption increased, with significant growth in coal-intensive countries like China and India, and oil-intensive nations such as Saudi Arabia. In Europe, energy use declined due to high prices and the war in Ukraine, leading to adaptations like fuel switching and energy sufficiency measures. CO2 emissions from energy combustion have consistently risen since 2021, with fossil fuels dominating the energy mix. The average energy intensity in G20 fell slowly, but not enough to meet Paris Agreement targets, which require faster decarbonization.

Decarbonization Efforts

Decarbonization progress has slowed, with insufficient reductions in carbon factors and energy intensity. Since 2000, G20 energy intensity has decreased by an average of 1.5% per year, far short of the almost 4% needed for a 2°C warming limit. Thermal power generation remains carbon-intensive, with coal consumption surging due to competition from renewables and high gas prices. Scenarios like EnerBlue (achieving updated NDCs) and EnerGreen (limiting warming below 2°C) highlight a significant emissions gap, underscoring the need for stronger policies.

Renewable Energy Growth

Renewable energy generation saw rapid advances, with solar power growing by 27% and wind by 13% in the G20. China led in installations and production, accounting for over half of wind and solar capacity additions. However, the power mix still relies heavily on thermal sources (60% carbon-intensive), and nuclear generation declined due to plant closures and maintenance.

Natural Gas Crisis in Europe

The EU faced a severe natural gas crisis in 2022, exacerbated by the Ukraine conflict and Western sanctions on Russia. Natural gas consumption dropped across sectors due to price hikes, milder weather, and energy-saving measures, primarily in buildings and industry. While consumption fell by about 12% compared to 2019, imports from Russia plummeted by 45%, compensated by increased LNG imports (up 47%) and supplies from Norway. Import substitution and diversification helped mitigate supply risks, but the crisis underscored Europe's dependency on fossil fuels.

Conclusions on Energy Transition

The report concludes that energy transition efforts are lagging, with CO2 emissions continuing to rise despite economic recovery. Insufficient decarbonization, slow shifts away from fossil fuels, and regional disparities (e.g., Asia versus Europe) hinder progress toward climate goals. Electrification, energy efficiency, and fuel switching are critical levers for future gains, but more aggressive policies are needed to accelerate the transition beyond current trajectories.
