Energy Efficiency
…emissions. However, IEA analysis has shown that despite this increased ambition, global progress on energy efficiency is slower than in the last decade. This is locking in greater levels of wasted energy, as well as higher costs and emissions.
Global progress on energy efficiency picks up in 2025
Global primary energy intensity – the main metric for tracking efficiency progress – is on course to improve by 1.8% in 2025, up from just 1% in 2024. Preliminary estimates indicate that several key economies, such as India and China, are showing some indications of stronger progress compared with their average since 2019…

Cars and Vans
More stringent and broader coverage of fuel efficiency standards for light-duty vehicles is needed
For cars and vans, increasing fuel efficiency standards is important as even in the Net Zero Emissions by 2050 Scenario, nearly 80% of cars and vans on the road in 2030 are still powered with internal combustion engines. Sales of heavier, less efficient SUVs reached around 46% of global sales in 2022, while electric vehicles were just 14% of sales. More and more countries are formulating vehicle efficiency standards and some are even putting in place zero-emission vehicle sales requirements. To be in line…

Appliances and Equipment
Standards and labelling can lift the average rate of energy efficiency improvement by two to three times
Based on global evidence from countries with Energy efficiency standards and labelling (EES&L) programmes, the average energy efficiency of new major appliances in these countries can increase two to three times the underlying rate of technology improvement. This can result in average energy reductions of 10-30% over 15 to 20 years in the stock of most regulated products across all countries.
In leading countries with strong regulations and long-running programmes which are regularly updated, the contribution could be much higher…

Hydrogen
Low-emissions hydrogen projects are set to grow strongly despite wave of cancellations and persistent challenges
Worldwide hydrogen demand increased to almost 100 million tonnes in 2024, up 2% from 2023 and in line with overall energy demand growth. The vast majority of this was met by hydrogen produced from fossil fuels without measures in place to capture associated emissions. Sectors that have traditionally used hydrogen, such as oil refining and industry, remained the biggest consumers.
The uptake of low-emissions hydrogen is not yet meeting the expectations set by industry and governments in recent years, especially in light of…

Wind
Wind has significant potential to boost growth in global renewable capacity
Electricity generation from renewables is expected to increase by 60% through 2030 – rising from 9 900 terawatt-hours (TWh) in 2024 to 16 200 TWh by the end of the decade. Wind accounts for almost a third of growth, second only to solar PV, which accounts for 60%.
Although wind power continues to face supply chain issues, rising costs and permitting delays today, global capacity is still expected to nearly double to over 2 000 gigawatts (GW) by 2030 as both advanced and developing economies tackle these barriers.

Bioenergy
Led by bioenergy, renewable fuels could approach 6% of energy demand from industry, buildings and transport in 2030
By 2030, renewable fuels are set to account for 5.5% of energy consumption from the industry, building and transport sectors. Demand is due to expand in all regions, but it is concentrated in China, Brazil, Europe, India and the United States, which collectively support more than two-thirds of the forecasted growth. All five countries and regions have dedicated support policies for several – and, in some cases, all – renewable fuels. These vary by fuel, sector and country, but they often include…

Methane Abatement
…many countries and companies have set targets to reduce methane emissions, with commitments now covering over half of global oil and gas production. However, methane emissions from the energy sector plateaued near record highs in 2025 – revealing a large implementation gap.
Still, there is significant scope for further action. Around 70% of fossil fuel methane emissions in 2025 came from the top 10 emitting countries. Meanwhile, the methane intensity of oil and gas production varies widely across countries – with the best performers scoring more than 100 times better than the worst.
And with energy security in focus around the world…

Electric Vehicles
…global sales of electric cars have continued to break records as electric models become increasingly affordable. Electric car sales exceeded 17 million globally in 2024, reaching a sales share of more than 20%. Just the additional 3.5 million electric cars sold in 2024 compared with the previous year is more than the total number of electric cars sold worldwide in 2020.
In 2025, sales of electric cars are expected to surpass 20 million, accounting for over a quarter of cars sold worldwide. In the first three months of 2025, global electric car sales were up 35% year-on-year.
