Grid investments
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores grid investments. Why is energy efficiency important for grid investments? As we enter the Age of Electricity, global electricity demand is rising rapidly – and so is the demand for the expansion of electricity grids. Energy efficiency can help close the gap between supply and demand, but often at a lower cost, and more quickly, than new generation and grid expansion. Key facts On average, energy efficiency costs less than half the amount it would cost to build new generation capacity and grid infrastructure, per unit of…

Sustainable Transport for Georgia: A Roadmap
…lives, including both benefits (access to goods and services) and drawbacks (congestion, air and climate pollution, and road injuries and deaths).Since national and municipal policies shape transport technology, infrastructure and operations, the report first examines the country as a whole, followed by Georgia’s largest cities. With road vehicles responsible for more than 98% of domestic transport energy use and carbon dioxide (CO₂) emissions, the focus is on road transport.Opportunities identified include improving vehicle efficiency – particularly by accelerating electric vehicle (EV) adoption – and cutting reliance on inefficient vehicles by reducing unnecessary car travel and shifting to buses, metro…

Jobs
…energy sector jobs are more prevalent in areas with lower unemployment rates. Energy efficiency investments also contribute to enhance the quality of jobs in other industries. Firms that invest in energy efficiency can significantly improve the quality of the working environment, with efficient lighting that provides increased visual comfort, or efficient ventilation systems that enhance air quality. By freeing up businesses’ spending through reduced energy bills, energy efficiency helps minimise cost pressures and supports employers in safeguarding jobs. Need more information?

Designing Energy Efficiency Policies to Enhance Affordability
…identified as a key challenge. In response, this report was developed to provide practical guidance on designing energy efficiency policies that support affordability, particularly in the buildings sector.As part of this work, the IEA conducted a survey with G7 governments to better understand the obstacles they face. On the consumer side, major challenges include the landlord-tenant split incentive, high upfront costs and administrative complexity. On the supply side, governments identified skills shortages and difficulties in reaching underserved communities.The report analyses the affordability-focused energy efficiency policies of G7 countries. These include targeted financial support, simplified programme design…

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…

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…

Affordability
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores affordability. Why is energy efficiency important for affordability? Energy efficiency measures can reduce energy bills for households, decrease energy poverty, and make access to energy services more affordable. Key facts Energy efficiency measures can reduce average household energy bills in advanced economies by up to one-third. In emerging economies, they can also improve access to energy services. For many products, such as refrigerators, highly efficient models use less than half of the energy of inefficient models. A best-in-class model can save up to…

Vehicle software and software-defined vehicles
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…

Policy options to accelerate distributed solar PV in Ukraine
…decentralisation in power generation can also support Ukraine in meeting its long-term decarbonisation goals, as set out in the 2030 National Energy and Climate Plan and the 2050 Energy Strategy. This report explores the current policy landscape for distributed solar PV in Ukraine and outlines three potential policy options to accelerate the deployment of this technology. It focuses on expanding the capacity of distributed solar PV to achieve the modelled results from IEA report Empowering Ukraine through a Decentralised Energy System, which outlines a pathway to rebuild and modernise Ukraine’s power sector amid ongoing attacks on energy infrastructure
