Global EV Outlook 2020
Entering the decade of electric drive? The Global EV Outlook is an annual publication that identifies and discusses recent developments in electric mobility across the globe. It is developed with the support of the members of the Electric Vehicles Initiative (EVI). Combining historical analysis with projections to 2030, the report examines key areas of interest such as electric vehicle and charging infrastructure deployment, ownership cost, energy use, carbon dioxide emissions and battery material demand.
This edition features case studies on transit bus electrification in Kolkata (India), Shenzhen (China), Santiago (Chile) and Helsinki (Finland). The report includes policy recommendations that incorporate…

World Energy Outlook 2012
World Energy Outlook 2012 Industry and government decision makers and others with a stake in the energy sector all need WEO 2012. It presents authoritative projections of energy trends through to 2035 and insights into what they mean for energy security, environmental sustainability and economic development. Oil, coal, natural gas, renewables and nuclear power are all covered, together with an update on climate change issues. Global energy demand, production, trade, investment and carbon-dioxide emissions are broken down by region or country, by fuel and by sector. Special strategic analyses cover: what unlocking the purely economic potential for energy efficiency could do, country-by-country and sector-by…

Evolving Energy Service Companies in China
Evolving Energy Service Companies in China Energy service companies (ESCOs) deliver energy efficiency projects that are financed through the resulting energy cost savings. ESCOs can thus unlock energy efficiency action by addressing barriers related to funding and technical expertise. Despite their potential, many governments still struggle to stimulate development of a market for ESCOs. Evolving Energy Service Companies in People’s Republic of China, (“China” hereafter) provides an overview of how China has built the world’s largest and fastest growing ESCO market over the past decades. This report highlights how the government’s strategic measures to set up key…

China’s Official Energy Finance in Emerging and Developing Economies
…state-owned commercial banks and export credit agencies have taken on a larger role, increasingly 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…

Energy Efficiency 2018
Analysis and outlooks to 2040 Energy efficiency can bring significant economic, social and environmental benefits. But while energy efficiency is improving around the world, its positive impact on global energy use is overwhelmed by rising economic activity across all sectors. Efficiency can enable economic growth, reduce emissions and improve energy security. The right efficiency policies could enable the world to achieve more than 40% of the emissions cuts needed to reach its climate goals without new technology. Energy Efficiency 2018 looks at why efficiency’s massive potential remains untapped, and through the new Efficient World Scenario explores what would happen if countries maximized…

Railway Handbook 2015
Produced in collaboration with the Union Internationale des Chemins de Fer The collaboration of the IEA and the UIC in collecting, elaborating, and presenting activity, energy, and CO2 emissions data was carried out for the fourth time through the release of the Railway Handbook 2015. For this edition, significant methodological improvements were implemented leading to better consistency between the different indicators presented in this Handbook, in addition to updates of the global data, as well as regional breakdowns for those regions that we consider the most relevant from the point of view of transport activity: European Union, USA, Japan, Russia…

Integrating Distributed Energy Resources in China
Lessons from international experience Like no other country in the world, the People’s Republic of China (hereafter, “China”) is witnessing rapid growth in distributed energy resources (DERs), including rooftop solar photovoltaics, battery storage and electric vehicle (EV) chargers. As China advances towards its carbon peaking and neutrality goals, these resources offer a unique opportunity to support a more flexible, efficient and resilient power system, provided their integration is well-managed.This report analyses recent trends in DER deployment across China and highlights the emerging challenges their growth poses for power system planning and operation, calling for renewed attention to…

Implementing Clean Energy Transitions
…in order to assess where gaps may arise and help governments and policymakers to explore other international policy experiences.The library groups transport policies within three overarching categories:Regulation, incl. standards and mandates: This includes fuel-economy standards, emission standards, blending mandates, charging standards and EV mandates. Incentives: This includes for both cases incentives for electric vehicle, modal shift, biofuels and scrappage schemes. Fuel excise taxes and carbon pricing are also included in this category.Information: This includes policies and initiatives focused on informing consumers, training, and networking.This library builts on the joint IEA/IRENA Policy and Measures database…

Clean Energy Transitions Programme 2019
Annual report 2019 Since the launch of the Clean Energy Transitions Programme (CETP) in November 2017, the IEA has significantly expanded its work to help accelerate energy transitions in major emerging economies. The CETP has played a critical role in both helping to build global momentum for clean energy transitions and in further strengthening the IEA family.
The CETP Annual Report 2019 summarises the programme’s activities in 2019, highlighting major achievements, successes and outcomes, as well as identifying opportunities for further collaboration with partners and potential partners. It also highlights activities planned for 2020.
The report reflects on the…

Clean Energy Transitions Programme 2020
…on energy markets and systems, and set out near-term actions that could help accelerate clean energy transitions.Relying on the independent, data-grounded approach and unique expertise of the IEA, the programme continues to be uniquely situated to provide targeted analysis and recommendations even as the crisis affects the energy sector. The IEA has done this through initiatives such as the Global Sustainable Recovery Plan and other efforts such as exploring ways to enhance private-sector investment in transmission in Southeast Asia; identifying ways to attract private power sector investment to fund sustainable recovery in Indonesia; engaging with partners…
