Uzbekistan
Despite being energy self-sufficient thanks to its gas sector, Uzbekistan's ageing infrastructure struggles to meet growing domestic demand. Losses, overuse and financing remain problematic. Wide-ranging reforms focused on improving and diversification the energy sector are being introduced and the government has adopted the Strategy of Actions 2017-2021, which prioritizes improving energy efficiency and increasing generating capacity and use of renewables. Uzbekistan is part of the EU4Energy Programme, an initiative focused on evidence-based policymaking for the energy sector.

Why the growth of energy service companies is uneven globally
ESCO The global annual ESCO market growth rate has more than doubled over the past five years Energy efficiency is one of the most cost-effective tools for enhancing energy security, reducing household energy bills and supporting countries’ efforts to reduce emissions. Energy service companies (ESCOs) – firms that develop and implement energy efficiency projects typically financed through verified energy savings – are playing a growing role in delivering energy efficiency improvements across buildings, industry and transport infrastructure worldwide. By integrating project development, financing and performance guarantees, ESCOs can offer a proven way to reduce upfront investment barriers and shift technical and…

India
Energy demand in India is growing rapidly with major implications for the global energy market. The Government of India has made remarkable progress in providing access to electricity and clean cooking while implementing a range of energy market reforms and integrating a high share of renewable energy sources into the grid. India, with a population of 1.36 billion and a fast growing economy, has seen its energy demand increasing rapidly as the country continues to urbanize and the manufacturing sector develops. This growing demand is met through various energy sources, with coal set to remain the largest source of…

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…

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…

Germany
Germany’s Climate Law sets out the framework for reaching net zero emissions by 2045. In order to achieve the ambitious Energiewende by 2030, 80% of all electricity supply will need to come from renewable energy sources (and 100% by 2035) and coal is to be completely phased out. Germany has been an early leader in offshore wind and solar PV and phased out nuclear power in 2023. Major legislative reforms in renewable energy planning and siting support targets of 100-110 GW of onshore wind, 30 GW offshore wind and 200 GW solar, alongside investments in 10 GW of…

Manufacturing and Trade Model
The IEA’s Manufacturing and Trade (MaT) Model was first developed for the 2024 edition of Energy Technology Perspectives (ETP) to produce scenario projections of manufacturing and trade across six key energy technology supply chains. These cover solar photovoltaics (PV), wind turbines, electric cars, batteries, electrolysers and heat pumps. This model is now used to generate detailed sector-by-sector and region-by-region long-term scenarios in IEA publications such as the World Energy Outlook and Global EV Outlook.The MaT model is part of the IEA’s broader modelling framework and is closely linked to the Global Energy…
