Energy Efficiency
…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.
The rate of global improvement in energy efficiency has been largely lacklustre since 2019, averaging around 1.3% annually. That’s down significantly from the average of around 2% per year between 2010 and 2019 – and well short of the goal of 4% by 2030 that was set at COP28 in Dubai in 2023, where nearly 200 governments agreed to work together to double the global average annual rate of energy efficiency improvements by 2030.

Heat pumps, powered by low-emissions electricity, are the central technology in the global transition to secure and sustainable heating. The Future of Heat Pumps, a special report in the IEA’s World Energy Outlook series, provides an outlook for heat pumps, identifying key opportunities to accelerate their deployment. It also highlights the major barriers and policy solutions, and explores the implications of an accelerated uptake of heat pumps for energy security, consumers’ energy bills, employment and efforts to tackle climate change.
Around 10% of space heating needs globally were met by heat pumps in 2021, but the pace…

Nuclear Power
A new era for nuclear energy beckons as projects, policies and investments increase
As the world’s second-largest source of low-emissions electricity after hydropower, nuclear power today produces just under 10% of global electricity supply. Now, fresh momentum around the world has the potential to open a new era for nuclear energy.
Power generation from the global fleet of nearly 420 active nuclear reactors is set to reach a record high in 2025 as Japan restarts production, maintenance works are completed in France, and new reactors begin commercial operations in various markets, including China, Europe, India and Korea…

Electrification
Country and regional highlights
Electrification gains momentum across countries and sectors
CO2 emissions
In the Net Zero by 2050 Scenario, from now to 2030 most electrification-related emission reductions occur in transport
Energy
The share of electricity in energy demand will need to increase by 4% per year to get on track with the Net Zero by 2050 Scenario
Technology deployment
New cars and new houses are the main areas for deployment of electrification technologies

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…
