Renewable energy is expanding the quickest in the road sector Renewable energy demand for road transport is projected to rise more than 2 EJ, reaching 8% of total road subsector energy use by 2030. Renewable electricity consumption for electric vehicles accounts for more than half of this growth, concentrated mainly in China and Europe as renewable electricity generation increases and electric vehicle fleets expand.Liquid biofuels make up most of the remainder, with biofuel demand growth concentrated in Brazil (40%), Indonesia (20%), India (15%), Europe (10%) and Canada (7%…

Renewable energy, excluding traditional uses of biomass, met only half of this increase, with its share in global heat consumption rising to 14% in 2024. Nearly 80% of global growth in renewable heat use was in the form of bioenergy (especially in industry) and renewable electricity (mainly in buildings).Industry sector renewable heat use grew the most in China over the last six years, driven by the expansion of industries such as metals, chemicals, textiles, food and beverages that increasingly use biomass residue and electricity for process heat…

Emissions fall in aggregate in advanced economies, most substantially in Europe, and decline in China from 2030 onwards, but they increase elsewhere.

Preliminary estimates indicate that several key regions are showing some signs of stronger progress compared to their average since 2019. For example, energy intensity progress in 2025 is estimated to be over 3% in the People’s Republic of China (hereafter “China”) and over 4% in India, well above their averages in the years since 2019. In the United States and the European Union (EU), on the other hand, progress in 2025 is set to fall to under 1% after several…

China, the United States, and the European Union continue to attract the bulk of clean‑energy capital, while many emerging and developing economies face persistent barriers, including higher financing costs and limited access to affordable capital. As a result, efficiency investment in these economies is growing far more slowly than in advanced economies and China. The IEA stresses the need to mobilise more finance, reduce investment risks, and expand suitable financing instruments to support the deployment of energy‑efficient technologies and infrastructure…
