Energy use is shifting fast, and the latest efficiency trend tells only part of the picture. For example, global energy related CO2 emissions reached 37.4 gigatonnes in 2023 while electricity demand in India rose 8% year over year, even as transport efficiency improved and grid needs kept expanding. The result is a dataset full of tradeoffs, from how power is made and moved to where it is ultimately consumed.
Key Takeaways
- In 2023, the average global efficiency (kWh/km) for passenger electric cars improved by 5% compared with 2022 models (IEA estimate in Global EV Outlook)

- Hydropower produced 4,200 TWh of electricity in 2023.
- Small-scale solar contributed 10% of total solar generation worldwide in 2023.
- In 2023, coal-fired generation in the United States was 1,713 TWh (EIA).
- In 2023, electricity demand in India grew by 8% compared with 2022.
- In 2023, global electricity-related energy efficiency investment requirements were estimated at $500–$1,000 billion per year (IEA).
- In 2022, the global average rate of improvement in energy intensity was 1.2% per year (not sufficient to meet net zero pathways).
- In 2022, worldwide electricity intensity of GDP (electricity consumption per unit GDP) improved by 2.0% compared with 2021 (IEA energy efficiency indicators).
- In 2023, global natural gas consumption was about 4,000 billion cubic meters of gas equivalent (IEA/WEO 2023 historical series).
- In 2023, global energy-related CO2 emissions were 37.4 gigatonnes (GtCO2) according to Ember’s Global Carbon Budget dataset.
Despite efficiency gains, energy use keeps rising, so investment and cleaner power must scale fast.

Demand & Intensity Interpretation
In the Demand and Intensity category, India’s electricity demand rose by 8% in 2023 versus 2022, showing a clear increase in how much electricity the country needs year over year.
Efficiency & Savings

Verified
2In 2022, the global average rate of improvement in energy intensity was 1.2% per year (not sufficient to meet net zero pathways).[14]
