                New Zealand

                New Zealand has a diversified energy mix, with significant production of both hydropower and geothermal. As the country embarks on an ambitious energy transition, it has many natural advantages, including a strong renewable resource base. New Zealand already has a low-emissions electricity system, with over 80% of electricity coming from renewable sources. The key challenge will be to decarbonise other end-use sectors through clean power and support investments in new technologies to achieve deeper emissions cuts across all sectors. Notably, the transport sector accounts for the highest share of emissions and is almost entirely dependent on oil while…

                GEVO 2026 - Chapter 8 The transition from mechanical to software-based vehicle control has been underway for decades and has accelerated dramatically with the rise of EVs. Pure-play EV makers have pioneered the shift towards high-level, continuously updateable software-based vehicle control, speeding up the development and rollout of new features. Vehicles are evolving into software platforms for which users can access subscription‑based premium features, in the same way as for smartphones. A new design paradigm is emerging, with EVs at the forefront The digital transformation of the car industry is most evident in the emergence of software…

                Portugal 2026 Executive summaryExecutive summary

                Thanks to steady expansion of hydropower, wind power generation and solar photovoltaics (PV) in recent years, Portugal has one of the lowest carbon intensities of electricity generation among IEA Member countries. Portugal is entering a mid‑transition that requires managing two interconnected energy systems that are moving in opposite directions: one is based on renewables and electrification and must scale up rapidly; the other is a legacy fossil fuel system that must decline in an orderly way to avoid stranded assets and price shocks. Electricity is becoming the central pillar of energy security and the main driver of emissions reductions.Portugal…

                Ireland faces strategic choices to align its energy, climate and socio-economic goals through 2035 Over the next decade, decision makers in Ireland will need to balance a range of trends and policy ambitions that have strong implications for the power sector. Ireland has set a range of policy goals spanning the next decade, from improving energy security by reducing its reliance on imported fossil fuels, to meeting its climate targets, expanding its housing stock, and supporting the growth of digital infrastructure such as data centres. These ambitions all have strong links to the country's power sector, with implications…

                United States

                The United States introduced major energy and climate policy reforms which put the country on a path towards a clean, secure and affordable energy system for a net zero economy. The reforms aim to strengthen infrastructure deployment and resilience, include a major focus on clean energy manufacturing, improving diverse supply chains and affordability, enhancing equity and the creation of high-quality clean energy jobs.
                The US plays a significant role in supporting international energy security as the world’s largest producer of oil and exporter of liquified natural gas. A wave of clean energy investment means the US is today…

                Energy Efficiency in China’s Buildings Sector

                Policy opportunities Over the past two decades, China has made significant strides in energy efficiency, with strong reductions in primary energy intensity across the economy and increased energy services. Much of China’s improvement has come from energy efficiency upgrades in industry and overall economic structural shifts. The buildings sector accounts for approximately 20% of its total final energy consumption and its intensity has decreased at a slower rate. There remains significant potential to unlock further energy savings through technical and policy initiatives in buildings.This report outlines opportunities for actions, targets and timelines that could improve energy efficiency in…

                Energy Policy Review Government action plays a pivotal role in ensuring secure and sustainable energy transitions. Energy policy is critical not just for the energy sector but also for meeting environmental, economic and social goals. Governments need to respond to their country’s specific needs, adapt to regional contexts and help address global challenges. In this context, the International Energy Agency (IEA) conducts Energy Policy Reviews to support governments in developing more impactful energy and climate policies.This Energy Policy Review was prepared in partnership between the Government of Korea and the IEA. It draws on the IEA’s extensive…

                Germany is at an important inflection point in its energy transition. As one era of its energy history draws to a close, another is coming clearly into view – the move away from nuclear, coal and Russian natural gas contrasted by the transition towards renewables, low-emissions hydrogen, heat pumps and electric vehicles (EVs). While the world has been buffeted by geopolitical and geoeconomic challenges in recent years, Germany has worked hard to accelerate its clean energy transition. This report seeks to provide Germany with timely advice on how it can progress towards its energy and climate goals, including in three…

                Nepal

                Almost the totality of the electricity generated in Nepal comes from hydropower. Most of the energy supply is from biofuels and waste as 21 million people still rely on traditional biomass for cooking. In 2000, 81% did not have access to electricity but with remarkable efforts from the government, only 6% of the population remain without access today.
