What Next for the Global Car Industry
…adoption of electric cars. In 2024, more than one in five cars sold globally was electric. These changes are increasingly posing challenges for incumbent car manufacturers, who are forced navigate a vehicle technology transition that is moving at different speeds in different markets.At the same time, growth in car sales has shifted to emerging economies including China since the turn of the century, with around half of global sales now in these regions. Production has also grown unevenly in different regions, especially since the pandemic. China’s car output reached a record 27 million in 2024, when it also…

Powering Ireland’s Energy Future
…Ireland has emerged as a frontrunner in integrating wind power, which supplied around a third of its electricity in 2024. As this power system transformation continues, electricity is set to be the backbone for achieving Ireland’s climate, energy and socio-economic ambitions, making electricity security critical to realising progress in key areas including housing, digital infrastructure, transport and heat. Going forward, Ireland faces strategic choices on how to align its ambitions while ensuring secure electricity supply to 2035.This report assesses the outlook for Ireland’s energy security to 2035, drawing on international experience and detailed power system modelling…

China’s Official Energy Finance in Emerging and Developing Economies
…through equity investments or guarantees. This shift suggests a move towards a more competitive – yet still state-directed – model of international energy engagement.These changes reflect a financing system adapting to new domestic and global circumstances rather than a withdrawal from China’s overseas energy activity. For clean energy deployment in particular, the evolving pattern presents both opportunities – including expanded equity participation and greater risk-sharing – and challenges linked to uneven availability of concessional or long-tenor finance.This report maps and analyses these changes through an energy sector-level dataset covering 2015 to 2024. It explores how China’s…

Energy security
…new peak demand records and resiliency challenges. In 2019, 1°C in outdoor temperature increase was associated with a 5 GW increase in peak electricity demand; with rising air‑conditioner ownership and increasing temperatures, this value rose to 7 GW in 2024 and could further rise to 12 GW in 2030 without further efficiency action. If India were to experience similar heatwaves as in recent years – with temperature anomalies of over 4°C – the additional peak load would amount to 47 GW. However, if all new air conditioners in India were highly efficient (e.g. through increased minimum energy performance standards), peak load during a heatwave could…

Delivering Sustainable Fuels
…enhance energy security, strengthen environmental sustainability and stimulate economic development, particularly in rural areas.If fully legislated and implemented, current and proposed national and international policies would put the use of sustainable liquid and gaseous fuels on a path to nearly double from 2024 levels by 2030 and quadruple by 2035. Progress must occur on multiple fronts to increase uptake and foster a large and diverse set of sustainable fuel pathways. This calls for a shared global vision for sustainable fuels, along with targeted policies to bridge costs gaps with conventional fuels, innovation to expand production potential, robust and mutually…

Global Hydrogen Review 2025
…significantly since the first publication of the Global Hydrogen Review in 2021. Low-emissions hydrogen production projects have gone from just a handful of demonstrations to more than 200 committed investments for projects that are increasing in number and in scale, reflecting the importance of hydrogen for climate goals, energy security and industrial competitiveness. Nevertheless, growth has not met all of the expectations raised at the start of the decade and remains uneven. Uncertainties about costs, infrastructure readiness and evolving regulatory frameworks all present barriers to faster deployment.This fifth edition of the Global Hydrogen Review takes stock of the…

Sustainable Transport for Georgia: A Roadmap
…infrastructure and operations, the report first examines the country as a whole, followed by Georgia’s largest cities. With road vehicles responsible for more than 98% of domestic transport energy use and carbon dioxide (CO₂) emissions, the focus is on road transport.Opportunities identified include improving vehicle efficiency – particularly by accelerating electric vehicle (EV) adoption – and cutting reliance on inefficient vehicles by reducing unnecessary car travel and shifting to buses, metro, walking and cycling, as well as intercity passenger and freight rail. These opportunities are presented as a coordinated and sequenced portfolio of policies designed to enhance transport efficiency and…

Outlook for Biogas and Biomethane
A global geospatial assessment Biogases play an important and growing role in energy systems. Produced locally using organic waste, biogas and biomethane can contribute to energy security, waste management, emissions reductions and agricultural development.In recent years, demand for biomethane – also known as “renewable natural gas” – has grown rapidly in many countries, supported by dozens of new policies. As a low-emissions substitute for natural gas, the use of biomethane has been targeted across a wide range of sectors, including power, industry, transport and buildings. This report presents a first-of-its-kind global geographical analysis of the untapped potential…
