Summary: World Energy Transitions Outlook 2024

Chapter 1: Key Findings of IRENA's 1.5°C Scenario and Achievement of 2030 Milestones

• 1.5°C Scenario: A pathway ensuring net-zero emissions by 2050 requires tripling renewable power capacity and doubling energy efficiency by 2030. This necessitates annual average additions of 1,044 GW of renewables by 2030.
• Progress: Renewable deployment was record in 2023 (473 GW added), concentrated in China, the EU, and the US. Despite this, much of the global south remains underinvested, hindering energy access and decarbonization goals.
• Challenges: Countries lack ambitious electrification plans and adequate storage infrastructure. Energy access deficits (685 million without electricity) threaten SDG7 and equity targets.

Chapter 2: Progress towards 2030 Milestones

• Renewable Capacity Growth: Solar PV dominates expansion (347 GW in 2023), but wind and bioenergy lag, requiring policy support. Achieving 11 TW by 2030 needs USD 1.5 trillion annual investment.
• Energy Efficiency: Improving by 4% annually to halve energy intensity. Electric vehicles and heat pumps are critical, but sales declined in 2023, highlighting missed opportunities.
• Finance Gaps: Energy transition investments rose to USD 2 trillion in 2023, but 90% remain concentrated in advanced economies. EMDEs face underfunding despite high needs, especially for grid expansion and storage.

Chapter 3: Power Sector Flexibility and Electrification

• Grid Enhancements: Strengthened grids and interconnections improve renewable integration. Battery storage needs to expand from 86 GW to 360–900 GW by 2030 to manage variability.
• Electrification: Direct electrification of transport, buildings, and industry is essential, requiring USD 3 trillion in investments by 2030. Demand-side management through smart grids enhances flexibility.
• Challenges: High upfront costs for storage and hydrogen limit deployment. Policy barriers include outdated market designs and regulatory hurdles, exacerbated by investment gaps in EMDEs.

Chapter 4: Skills Requirements and International Collaboration

• Workforce Development: Building skilled labor is critical for renewable manufacturing and operations. Training programs, especially for grid management and hydrogen production, address current shortages.
• Collaborative Finance: Public-private partnerships and wealth taxation (e.g., on ultra-high-net-worth individuals) can bridge funding gaps. Need equitable distribution to reduce disparities between the Global North and South.
• Philanthropic Role: Philanthropy funds "unbankable" projects but remains underutilized (USD 7–13 billion/year in climate mitigation), with funding concentrated in high-income countries.

Chapter 5: Socio-Economic and Welfare Impacts

• Welfare Gaps: Energy transitions under the 1.5°C pathway improve welfare for some, but gaps persist, especially in Africa. Flexible finance and inclusive policies are needed to address distributional inequalities.
• Energy Access: By 2030, 660 million lack electricity and 1.8 billion lack clean cooking. Solutions include off-grid renewables and financing mechanisms for DRE systems in remote areas.
• Distributional Justice: International collaboration must fund clean energy projects in LMICs, prioritizing equity. Climate finance needs to scale beyond loans to grants, reducing debt burdens.

Overall Recommendations

• Scale Renewables: Accelerate renewable capacity deployment through supportive policies, grid upgrades, and grid flexibility solutions.
• Boost Finance: Implement international wealth taxes, leverage philanthropic funds, and de-risk investments in high-potential regions.
• Prioritize Equity: Ensure just transitions deliver energy access for all, reducing socio-economic disparities while meeting climate goals.
