Efficient Grid-Interactive Buildings in India
Status and opportunities This report assesses the opportunities for efficient grid-interactive buildings (EGIBs) to support India’s clean energy transition. EGIBs unite energy efficiency, smart digital technologies and demand-side flexibility, allowing them to optimise energy use, shift or reduce peak demand and better align consumption with renewable energy generation.The buildings sector is central to clean energy transitions in a context where rapidly increasing electricity demand is driven by cooling and appliance use, and the share of variable renewable energy in electricity generation is continuously growing. Without targeted action, unmanaged peak loads and variable supply could jeopardise grid…

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…

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 savings
…significantly, efficiency also helps improve people’s lives by increasing access to additional energy services. Key facts In the last two decades, efficiency measures have generated over 27 EJ of energy savings in IEA countries alone, equivalent to 20% of total energy demand.The industry (including manufacturing) and services (including commercial buildings) sectors generated over half of the savings. In transport, most efficiency gains were achieved in passenger vehicles. Key analysis In selected IEA countries, increased economic activity – people using more energy services, firms increasing their production, and people travelling more – pushed energy use upwards by around 22% since 2000. However…

Delivering Sustainable Fuels
Pathways to 2035 Sustainable fuels – including liquid biofuels, biogases, low-emissions hydrogen and hydrogen-based fuels – offer multiple benefits for the energy sector. They complement electrification and energy efficiency in energy transitions, and are particularly important for sectors that continue to be reliant on fuel-based solutions such as aviation, shipping, and parts of road transport and industry. Sustainable fuels can also enhance energy security, strengthen environmental sustainability and stimulate economic development, particularly in rural areas.If fully legislated and implemented, current and proposed national and international policies would put the use of sustainable liquid and gaseous fuels on a…

Energy security
…in Japan the strongest reductions were in oil imports, due to some of the most stringent fuel economy standards both for passenger and commercial vehicles. A closer look at electricity security Energy efficiency and demand response policies can also contribute to electricity security by reducing the risk of outages resulting from peak demand.Different programmes have demonstrated success in reducing peak electricity demand and preventing outages. Studies in the United Kingdom and the United States show that real-time feedback and pre-event communications lead to reductions in consumption and peak demand of about 3%.This is especially relevant in…
