Health
…energy retrofits led to a 81% reduction in self-reported illness among households. Meanwhile, the evaluation of the Warm Up New Zealand Programme concluded that 90% of all benefits are health-related, with hospital admissions for respiratory conditions dropping by 43%, saving the country over USD 1 billion in health costs. In Ireland, in an analysis of the Warmth and Wellbeing Scheme, participants report that the improved efficiency of their homes reduced the number of doctor visits by 50% and lowered hospital admissions by 40%.In addition to physical health, energy efficiency can also lead to improvements to mental health…

…price premiums are positive impacts for building owners, it is important to also consider the effect energy efficiency improvements have on building occupants or renters. Increasing the quality of a rented space through energy efficiency can achieve increased thermal, noise and light comfort; improved health, safety and security, and reduced energy bills and operational costs. These benefits can result in improved tenant satisfaction and improved ability to rent the space.Rent increases associated with the retrofit should be in line with energy cost savings to maintain affordability. Policy tools, such as mandatory energy performance ratings, financial incentives and tenant protections…

Financing CCUS at Scale
How to Mobilise Private Capital Carbon capture, utilisation and storage (CCUS) is an important area of attention for governments and financiers as both look to balance policy and investment goals. Recent financial investment decisions of major projects show promise in a sector that is gaining momentum, but its future success depends on viable business models and effective risk allocation across the value chain.In this context, Financing CCUS at Scale is the IEA’s latest report on what it takes to move CCUS projects from the drawing board to operation. Building on expert interviews with leading financial institutions, the report…

Overview graphic: key technology trends for EVs
GEVO 2026 - Chapter 8 Electric vehicles (EVs) are increasingly at the centre of innovation in the automotive sector, bringing advances that extend far beyond developments in batteries and power electronics, thanks to several mutually reinforcing factors. Key technology trends are aligning in favour of EVs Battery electric vehicles (BEVs) are mechanically simpler than internal combustion engine vehicles (ICEVs) or hybrids, making them more compatible with digitalisation and automation. The relative simplicity of electric drivetrains enables shorter development cycles for new vehicles, allowing emerging technologies to reach BEVs sooner than vehicles with other powertrains.While the transition from mechanical to software…

Prospects for Natural Gas Certification
…from North America. As certification continues to evolve, opportunities remain to improve consistency, transparency and coverage across the full supply chain. To support further progress, the report outlines potential policy actions for governments to consider –such as international collaboration on harmonisation, setting minimum standards for certification, and exploring ways in which certification could complement emerging regulatory and market frameworks.While not a standalone solution, certification can enhance transparency and performance on GHG emissions across natural gas supply chains. This can support broader efforts to reduce emissions and strengthen energy security by improving accountability and easing comparability across different supply chains.

Assessing emissions from LNG supply and abatement options
…availability and reporting of emissions data from the natural gas value chain in recent years. However, estimates are still subject to a high degree of uncertainty. This interim report estimates emissions from LNG supply today, based on the latest and best available data including those from scientific studies and measurement campaigns. It covers upstream production and processing of natural gas, pipeline transmission from processing facilities to export terminals, liquefaction processes, shipping and regasification at import terminals. It considers methane emissions, flaring, naturally occurring sources of CO2 and energy consumption from across the supply chain. It also explores mitigation options, c...

Multiple Benefits of Energy Efficiency for Business
Energy efficiency is often described as the “first fuel” because the cheapest and most secure energy is the energy that is not used. For businesses, this begins with a straightforward benefit: lower energy bills. In many cases, efficiency investments can pay back quickly through reduced energy costs alone. However, the value of energy efficiency extends beyond energy savings.This report builds on the IEA’s work on the multiple benefits of energy efficiency and focusses on how these gains materialise in businesses. Key benefits range from productivity and product quality improvements to brand image or health benefits for employees and…

Vehicle-to-grid technology
GEVO 2026 - Chapter 8 With the rollout of smart and bidirectional charging, EV owners can reduce charging costs and, in some cases, generate revenue by participating in grid services, such as frequency regulation. Load shifting and vehicle‑to‑grid (V2G) capabilities provide substantial electricity system benefits, helping reduce peak demand and potentially limiting the need for future grid investment – benefits for which EV owners can be compensated. Vehicle-to-grid charging holds the promise of alleviating grid constraints but barriers remain The rollout of EVs is a major driver of global electricity demand growth. Residential EV charging can draw more power than…

Heat Pump Taxonomy
…proposed taxonomy that focuses initially on heat pumps used as primary heating equipment in buildings, and that could be gradually expanded to other sectors. It introduces a structured classification framework based on source, sink and product characteristics. Advancing towards a common taxonomy supports cross-country comparability and facilitates international collaboration towards strengthening the evidence base for policy making and industry planning.The Heat Pump Taxonomy Technology Explorer offers an accessible, interactive way to explore different heat pump types available in the market with fact sheets summarising their technical characteristics, major regional markets and applications.

Ultra-fast charging batteries
GEVO 2026 - Chapter 8 New power‑electronics materials, battery cell technologies and battery pack architectures are enabling more efficient, higher‑voltage – and therefore faster – charging systems. Advances in batteries and power electronics are improving EV performance Over the past decade, average EV battery pack energy density (Wh/kg) has increased by around 60%, while prices have fallen by roughly 75%. Moreover, in 2023, battery-related patents accounted for 40% of all energy-sector patents, suggesting that more developments are still to come. At the same time, new power‑electronics materials, battery cell technologies and battery pack architectures are enabling more efficient, higher‑voltage – and…
