Energy Efficiency 2025 Buildings
How and where is energy used? Total final consumption in 2024 was over 450 EJ and has grown by around 25 EJ since 2019. Buildings account for around 30% of global energy demand and have contributed around 20% of the growth in total demand since 2019. The residential sector makes up about 70% of total energy demand in buildings, while the remaining 30% is used in commercial and public buildings.In advanced economies, most energy in homes is used for space and water heating, together accounting for about 70%. This is followed by the use of electrical appliances, such as refrigerators, televisions…

Energy System Resilience Executive summary
…households have endured severe blackouts, with some areas – including the capital, Kyiv – losing access to power for 17 hours or more on a daily basis. As of mid-January, Ukraine's electricity demand reached 18 gigawatts (GW), while the power system's capacity stood at roughly only 11 GW – a 7 GW deficit that has forced rolling blackouts, threatened heating and water systems during severe sub-zero conditions, and endangered essential services. In response to these extreme challenges, Ukraine has showed extraordinary determination to pursue a new architecture of energy resilience through decentralised electricity and heat generation, complemented by mobile...

Multiple Benefits of Energy Efficiency for Business Health and well-being
Energy efficiency can improve working conditions, increase employee productivity and reduce sick leave Energy efficiency improvements can enhance working environments and worker health. By reducing waste heat, air pollutants and other process inefficiencies, they lower health and safety risks while improving comfort and working conditions.In manufacturing, these effects can be direct. For example, in electronics manufacturing, conventional soldering requires thermal pre-heating cycles that exposes workers to high ambient heat as well as safety risks. Replacing this with induction heating enables localised heating of the material, reducing energy demand by around 70% while eliminating heat stress and safety hazards…

Universal Access to Clean Cooking in Africa Implications and policy considerations
A new recipe for success? Progress on clean cooking requires efforts from a wide range of stakeholders. These include efforts to enhance countries’ policy frameworks, address consumer affordability and other barriers to adoption, cultivate a skilled workforce and mobilise additional financing to the sector – themes discussed in this chapter.Access to low-cost debt will be key for companies to grow their customer base quickly. In the ACCESS, the share of debt financing in the sector increases from 35% today to over 50%. This depends on more financiers being able to assess and appropriately price risk clean cooking companies and…

Gas Market Lessons from the 2022-2023 Energy Crisis Anatomy of a natural gas crisis
Sudden and drastic reduction in Russian pipeline gas deliveries to Europe In the run-up to the gas supply shock, Russian natural gas (pipeline and LNG combined) accounted for a growing share of European gas supply. Prior to 2010, Russian supply made up a relatively steady 30% of the European Union’s gas supply. However, the combination of plateauing demand and rapid decline in EU domestic production, which started in the early 2010s (linked to the decision to phase out the historical Groningen gas field in the Netherlands), led to growing dependency on gas imports across the European Union. The…
