Transitioning away from fossil fuels: A roadmap based on renewables,electrification and grid enhancement<\/a><\/em>, the International Renewable Energy Agency (IRENA) warns that beyond today\u2019s energy security concerns, current energy systems remain structurally unprepared to meet the 1.5\u00b0C climate goal.<\/p>\n\n\n\nThe report, released in collaboration with the Brazilian COP30 Presidency ahead of the Copenhagen Climate Ministerial, finds that whilst the global goals of tripling renewable power capacity and doubling energy efficiency improvements by 2030 remain essential \u2013 they are not alone sufficient to achieve the global energy transition.<\/p>\n\n\n\n
As demand rapidly increases across transport, industry, buildings and digitalisation, the transition must now focus on electrifying these end-use sectors while transitioning away from fossil fuels.<\/p>\n\n\n\n
IRENA\u2019s revised 1.5\u02daC Scenario in the forthcoming World Energy Transition Outlook<\/em> sees electricity in global consumption rise from 23% today to 35% in 2035 and over 50% in 2050, with the rising demand mostly met by renewables. It envisages the share of fossil fuels declining across sectors from 80% today to 50% in 2035 and 20% or less in 2050.<\/p>\n\n\n\n\u201cThe world must adapt to a new energy reality\u201d, said IRENA Director-General Francesco La Camera. \u201cBeyond the goals of tripling renewables and doubling energy efficiency lies the wider challenge of transforming entire energy systems and reducing fossil fuel use across supply and demand. Electrification and fossil fuel phase-out are inseparable and must advance together.\u201d<\/p>\n\n\n\n
La Camera added: \u201cIRENA\u2019s revised roadmap clearly shows that electrification with renewables serves multiple policy goals. It contributes to climate mitigation, enhances energy security by boosting independence from imported fossil fuels and bolsters economic competitiveness through the creation of new industrial value chains and innovation. Furthermore, cost-competitive renewables support affordable electricity prices for households and industry.\u201d<\/p>\n\n\n\n
The report highlights that electrification is becoming the primary structural driver of fossil fuel decline across all major end-use sectors. Transitioning away from fossil fuel would mean a complete restructuring of energy infrastructure and investment allocation.<\/p>\n\n\n\n
Countries must simultaneously invest in grids, storage and system flexibility to ensure reliable, secure and affordable electricity systems capable of supporting growing demand.<\/p>\n\n\n\n
However, infrastructure has become a critical bottleneck, with around 2 500 gigawatts of wind and solar awaiting connection to grids. Upgrades by 2035 and 2050 will not be achieved without fasttracked permitting and scaled-up investment. IRENA estimates grid investment needs at USD 1.2 trillion per year on average, more than double the USD 0.5 trillion invested in 2025.<\/p>\n\n\n\n
Significant investments will also be needed in hydrogen and alternative fuels supply chains as well as electrification of end-use technologies and their enabling infrastructure \u2013 from EV charging and building retrofits to construction for electric heating and cooling and industrial electrification.<\/p>\n\n\n\n
La Camera concluded: \u201cThe speed of the fossil fuel phase out will ultimately be determined by how quickly economies electrify. To keep the 1.5\u00b0C goal within reach, the world needs a clear global direction of travel. IRENA data supports the establishment of a global electrification target for 2035, complemented by targets for grids and system flexibility.\u201d<\/p>\n\n\n\n
Today\u2019s report also underlines the importance of monitoring progress on electrification, grid enhancement and fossil fuel decline to support implementation and guide international cooperation.<\/p>\n\n\n\n
At COP28, the UAE Consensus and the First Global Stocktake under the Paris Agreement called for a tripling of renewables and doubling of energy efficiency by 2030. It also established an important foundation for the transition away from fossil fuels (TAFF). The TAFF roadmap, launched by the COP30 Brazilian Presidency and supported by IRENA, provides an important pathway to advance climate, energy security and development objectives in parallel.<\/p>\n\n\n\n
IRENA stands ready to inform the global discourse in the lead-up to COP31 in Antalya and to support countries through analysis, partnerships and country engagement.<\/p>\n\n\n\n
