Global Energy Review 2026 Technology: Battery storage
Battery storage is the fastest growing power technology today. In 2025, 108 GW of new battery storage capacity was deployed worldwide, 40% more than in 2024. Installed capacity is now eleven times higher than in 2021. Lithium‑iron phosphate (LFP) batteries now account for around 90% of deployments; while less energy‑dense than rival chemistries commonly used in EVs, LFP batteries are typically cheaper and better suited to more frequent cycling. Just five years ago, the market share of LFP batteries in deployments was well below 50%. Around 80% of new battery capacity in 2025 was utility‑scale. The remainder was behind-the…

The next wave of LED lighting: Smarter, circular and more efficient
lighting commentary The first LED revolution reduced energy use worldwide – and a second wave of deployment is now taking shape As the world enters the Age of Electricity, lighting remains one of the most visible – and widespread – parts of our energy use.The IEA estimates that lighting in buildings and outdoor applications accounts for the majority of overall lighting electricity demand. In 2024, around 8% of global electricity demand – or about 2 200 terawatt hours (TWh) – was attributed to lighting in buildings and outdoor applications, excluding industry and agriculture. These figures reflect the latest available data and define the scope…

China’s Official Energy Finance in Emerging and Developing Economies Case 7. Palembang waste-to-energy plant
…The project broke ground in September 2024 with China Power Engineering Consulting Group as the EPC contractor, with operations expected to start in 2026. It contributes directly to Indonesia’s plan to deploy 30 WTE plants nationwide by 2029 and support the country’s broader low-carbon and circular-economy goals. Financing model and China’s role The project is structured as a build–own–operate public–private partnership under a 30-year concession. The Palembang municipal government guarantees waste supply and pays a regulated waste-treatment fee – capped at IDR 500 000 per tonne (about USD 33) – which anchors a…

Global Methane Tracker 2025 Understanding methane emissions
…activity, but there are also indications that a warming climate is driving up emissions from natural sources such as wetlands. Methane is responsible for around 30% of the rise in global temperatures since the Industrial Revolution, and making rapid and sustained reductions in methane emissions is critical for limiting near-term warming. Methane (CH4) has a much shorter atmospheric lifetime than carbon dioxide (CO2) – around 12 years, compared with centuries – but it absorbs much more energy while it remains in the atmosphere. Methane also affects air quality because it can lead to ground-level (tropospheric) ozone, a dangerous pollutant. Methane…

Asset values
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores asset values. Why is energy efficiency important for asset values? Energy efficiency can increase the value of assets, such as homes, buildings or equipment, and lead to lower vacancy rates and longer equipment lifespans. Key facts Energy efficient buildings can command a premium on sale and rental price in both the residential and commercial sectors. Studies show that sale price premiums for energy efficient buildings range from 3% to 15% in residential buildings and 13 to 20% in commercial buildings. Key analysis Studies show that individuals…

Pledges to Progress 2025 Summary of results
The Turning Pledges into Progress framework contains a total of 25 metrics in three categories: 1) target setting (“Targets”), 2) strategies for implementation (“Strategies”), and 3) disclosure and reporting (“Disclosure”). Target setting comprises six metrics related to emissions reductions and investment in clean energy. All the signatories to the Oil and Gas Decarbonization Charter (OGDC) are assumed to have the aim of achieving these targets. Strategies for implementation comprise eight metrics that describe steps companies can take to achieve these targets; and disclosure and reporting comprises 11 metrics allowing stakeholders to assess how companies publicly report information relevant to achieving the OGDC goals…

Portugal 2026 Executive 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…

Portugal 2026 Policy recommendations for Portugal
Energy policy landscape 1. Adopt a national roadmap based on bottom-up sectoral agreements to support timely and cost effective emissions reductionsPortugal has established a clear long-term direction for its energy transition through the Roadmap for Carbon Neutrality 2050, the Basic Climate Law, and the National Energy and Climate Plan (NECP) 2030. The NECP commits to reducing GHG emissions by 55% by 2030 (vs. 2005 levels) and achieving climate neutrality by 2045. Strong progress has been made, with emissions down 43% in 2024, driven mainly by decarbonisation of electricity supply. Portugal is now entering a mid-transition, in which further…

How governments can best support consumers during this energy crisis
How governments can best support consumers during this energy crisis The conflict in the Middle East has triggered a major shock to global energy markets, with the effective closure of the Strait of Hormuz triggering the largest supply disruption in the history of oil markets and significantly impacting supplies of natural gas and a range of energy-related commodities.As concerns over supply security have grown, prices have risen across several parts of the energy system, increasing pressure on household budgets, public finances and economic activity more broadly. In response, many governments have announced emergency measures to protect consumers from…

World Energy Outlook 2022 Energy security in energy transitions
Energy security is not just about having uninterrupted access to energy, but also about securing energy supplies at an affordable price. It is a topic of perennial importance, and is once again high on the policy agenda as a result of the global energy crisis sparked by Russia’s invasion of Ukraine. The surge in energy prices has been on a large enough scale to worsen considerably the global economic outlook, causing difficulties for households and industrial operations alike, and leading many governments to recalibrate their policy priorities. Energy transitions offer the chance to build a safer and more sustainable…
