The energy transition is a pathway toward transformation of the global energy sector from fossil-based to zero-carbon by the second half of this century. At its heart is the need to reduce energy-related CO₂ emissions to limit climate change. Decarbonisation of the energy sector requires urgent action on a global scale, and while a global energy transition is underway, further action is needed to reduce carbon emissions and mitigate the effects of climate change. Renewable energy and energy efficiency measures can potentially achieve 90% of the required carbon reductions.

The energy transition will be enabled by information technology, smart technology, policy frameworks and market instruments. IRENA has assessed decarbonisation pathways through REmap, and is equipped to support and accelerate the energy transition by providing the necessary knowledge, tools and support to Member countries as they increase the share of renewable energy in their power sectors.

Our energy transition work is built around three pillars:

Power sector transformation knowledge: knowledge products and methodologies.

Energy system models and data: techno-economic and electrical models with associated data.

Energy planning support: application of knowledge and modelling tools to support member countries.
