Global EV Outlook 2025 Trends in electric car affordability
Falling battery pack prices and intensifying competition underpin progress in electric car affordability Today, electric cars often have a lower total cost of ownership than ICE cars over the vehicle lifetime, due to reduced fuel and maintenance expenses. However, reducing the purchase price gap will be key to broader uptake. In Europe, for example, respondents to a 2023 survey by the European Commission identified the price of battery electric cars as the main barrier to adoption. While battery electric car prices generally fell in 2024, the price gap with ICE cars remains in most regions. Electric car affordability has made…

Outlook for Biogas and Biomethane Introduction to biogas and biomethane
Biogas is a mixture of methane, CO2 and small quantities of other gases produced by anaerobic digestion of organic matter in an oxygen-free environment. Its precise composition depends on the type of feedstock and the production pathway. The methane content of biogas typically ranges from 45% to 75% by volume. Biogas is usually produced using the following technologies: Biodigesters: These are airtight systems (e.g. containers or tanks) in which organic material is broken down by naturally occurring micro-organisms. Contaminants and moisture are usually removed before use of the biogas. Landfill gas recovery systems: The decomposition of municipal…

Global Energy and Climate Model About the Global Energy and Climate Model
Overview Since 1993, the IEA has provided medium- to long-term energy projections using a continually evolving set of detailed, world-leading modelling tools. First, the World Energy Model (WEM) – a large-scale simulation model designed to replicate how energy markets function – was developed. A decade later, the Energy Technology Perspectives (ETP) model – a technology-rich bottom-up model – was developed for use in parallel to the WEM.Over the past four years, the IEA has worked to develop a new integrated modelling framework: the IEA’s Global Energy and Climate (GEC) Model. This model is now the principal tool…

Indicators Handbook for Just and Inclusive Energy Transitions Key findings from workshops on challenges and opportunities for tracking progress on just and inclusive energy transitions
Several challenges and opportunities emerged from the seven workshops. These include: Data improvements and digital opportunities Improving the availability of disaggregated data offers new ways to monitor key just transition dimensions.Clean energy programmes and policies can affect groups differently. Indicators tracking their just and inclusive dimensions, therefore, require disaggregated data that allow for intersectional analysis of key socio-economic factors such as gender, age, disability, household tenure, migration status or rural-urban divides. While the availability of disaggregated data remains a fundamental challenge for tracking just transitions across the world, improving it also represents a major opportunity for policymakers…

Financing Electricity Access in Africa Beyond new connections
Providing an affordable, equitable and quality service Affordability constraints can prevent households from gaining access to electricity or from taking advantage of electricity services once a connection is made. An estimated 220 million people in sub-Saharan Africa (around 40% of those without access) would find the basic bundle unaffordable, rising to 400 million for the essential bundle (65% of those without access). Filling this affordability gap would cost an additional USD 2-10 billion per year, via supply-side subsidies to reduce developer costs, demand-side subsidies to reduce consumer costs, or reductions in financing costs.The cost of capital for electricity access projects…

Multiple Benefits of Energy Efficiency for Business Operational benefits
For every dollar in energy cost savings, productivity gains can deliver up to an extra 30 cents of value Energy efficiency measures can improve how firms use labour, equipment and materials, leading to gains that go beyond reduced energy use. These improvements are often driven by more efficient, precise and optimised processes. By reducing losses – such as excess heat, inefficient combustion or friction – equipment operates more smoothly and reliably. Electrified processes can further enhance efficiency by reducing the number of moving parts and points of failure.This improved performance leads directly to higher productivity. More efficient production lines enable better…

Electricity 2026 Demand
The Age of Electricity has arrived, underpinned by strong demand growth As the Age of Electricity moves apace, demand is on a solid upward trajectory in our five-year forecast period from 2026 to 2030. Amid robust growth, the next five years will add on average 50% more electricity demand per year than over the past decade. The brisk pace will be supported by growing industries, electric vehicles, space cooling, and data centres, among many other end uses. Electricity consumption is now projected to grow at least 2.5 times faster than overall energy demand, hastening the world’s transition…
