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…

Global Energy Review 2025
Global Energy Review 2025 This edition of the Global Energy Review is the first comprehensive depiction of the trends that took place in 2024 across the entire energy sector, covering data for all fuels and technologies, all regions and major countries, and energy-related carbon dioxide (CO2) emissions. The latest data show that the world’s appetite for energy rose at a faster-than-average pace in 2024, resulting in higher demand for all energy sources, including oil, natural gas, coal, renewables and nuclear power. This growth was led by the power sector, with demand for electricity rising almost twice…

Energy Efficiency 2024 How can energy efficiency alleviate rising heatwave-driven electricity demand?
Another year of high temperatures leads to new electricity demand records and power outages Global temperatures have reached new heights in recent years. 2023 was the warmest year on record, and 2024 is on track to beat it. The frequency and intensity of heatwaves are increasing, causing extreme temperatures of up to 50ºC in some regions, with multiple national temperature records broken during 2024. Ensuring that cooling needs are met is of primary importance. The extreme temperatures are driving strong demand for much-needed cooling technologies such as air conditioners. However, these are also pushing up electricity use to record…

Country
Poland
Poland’s energy system has seen progress on energy transition, despite its reliance on domestic hard coal and lignite. For example, Poland has one of the fastest growing solar PV markets in the European Union and has also seen a strong uptake of heat pumps. Poland is pushing to become a major player in offshore wind, aiming for at least 3.4 GW of capacity by 2030. However, stronger efforts are needed across all sectors to accelerate energy transition and Poland would benefit from greater electricity interconnections with the rest of Europe.

Renewables 2021 Renewable heat
Recent trends Global progress on conversion to renewable heat has been limited Heat is the world’s largest energy end use, accounting for almost half of global final energy consumption in 2021, significantly more than electricity (20%) and transport (30%). Industrial processes are responsible for 51% of the energy consumed for heat, while another 46% is consumed in buildings for space and water heating, and, to a lesser extent, cooking. The remainder is used in agriculture, primarily for greenhouse heating. Global heat demand declined by 2% in 2020, primarily due to the curtailment of economic activity as a result of…

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…

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…

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…
