Summary of "Power More with Less: Scaling Up Energy Efficiency for Growth and Energy Security"

Core Content

This document outlines the World Bank Group's (WBG) approach to scaling up energy efficiency (EE) as a strategic priority to address current development challenges. It emphasizes the importance of EE in achieving economic growth, energy security, and sustainable development, particularly for low- and middle-income countries (LICs and MICs). The report highlights the need for a more systematic and collaborative approach to unlock EE's potential and overcome the barriers that have limited its adoption and impact.

Main Points

• Energy Efficiency as a Key Solution: Energy efficiency is a low-cost, largely untapped energy resource that offers multiple socioeconomic benefits. It can significantly reduce energy demand and costs, improve energy security, and contribute to climate goals.
• Economic Returns: Every dollar invested in EE yields $3 to $5 in returns, with substantial fiscal savings and enhanced competitiveness for businesses.
• Global Context: Despite progress, global energy efficiency is still insufficient. Almost two-thirds of primary energy is not used productively, and energy demand is expected to rise by 30% over the next decade. EE must be scaled up to meet these challenges, especially in sectors like cooling, data centers, and energy-intensive industries.
• Challenges in Scaling EE: Market failures such as lack of policy support, weak institutions, limited financing, and poor data access have hindered EE adoption. In many LICs and MICs, these barriers make EE investments less attractive, especially for those with longer payback periods.
• WBG Experience and Portfolio: The WBG has invested in EE for over three decades and has a well-documented portfolio of $6.71 billion in EE lending from FY15 to FY24. EE is more cost-effective than clean energy supply, with a cost of 0.63 US¢ per kWh saved compared to 3-8 US¢ per kWh for clean energy. The report includes case studies and lessons learned from successful programs.
• Need for a Programmatic Approach: A structured, long-term programmatic approach is necessary to scale EE across sectors. This includes the development of policies, regulations, and market mechanisms that enable EE to be implemented effectively.
• Concessional Financing: The report argues for the use of concessional financing to help overcome high capital costs and market barriers, especially in LICs and MICs. It estimates that concessional financing could support up to $6.6–7.1 billion in EE investments for a typical MIC and over $10 billion for a typical LIC.
• Ecosystem Development: A supportive ecosystem is essential for EE scaling. This includes institutional development, knowledge sharing, financial mechanisms, and collaboration between governments, the private sector, and donor partners.
• LEAP Framework: The LEAP (Leverage, Empowerment, Advocacy, and Partnerships) framework is proposed as a strategic tool to guide the scaling of EE. It emphasizes the need for better leverage, empowerment through capacity building, global advocacy, and partnerships to drive EE initiatives.

Key Recommendations

For Governments

• Embed EE in national development plans and strategies.
• Strengthen policy frameworks, including building codes, equipment standards, and energy pricing reforms.
• Support EE through institutional governance and data analysis capabilities.
• In underdeveloped markets, invest in public facilities to lead by example and spur demand for energy-efficient services and equipment.
• Implement low-cost measures such as awareness campaigns, behavior change, and optimization of heating and cooling systems.

For Multilateral Development Banks and Donor Partners

• Advocate for EE in national strategies and provide technical support.
• Assist in the design and development of pilot programs with a clear path to scaling.
• Use public financing, concessional funds, and risk mitigation tools to unlock commercial financing.
• Share successful models, approaches, and lessons (including failures) to support global communities of practice.

For the Private Sector

• Engage with governments and donor partners to identify and address market barriers.
• Replicate successful business models and develop bankable financing solutions.
• Participate in knowledge-sharing forums to contribute to the global EE ecosystem.

Conclusion

The report concludes that while the foundations for scaling EE are largely understood, the biggest challenges remain political will and resource mobilization. The WBG is prepared to support countries through programmatic engagements, knowledge-sharing platforms, and partnerships. A concerted effort across all stakeholders is essential to unlock the full potential of EE and achieve the goals of growth and energy security.

Key Figures and Data

• EE can save a typical MIC over $11 billion in power system costs by 2050.
• EE investments should make up about 40% of global energy investments by 2050 to meet net-zero goals.
• EE investments need to triple to $1.8–1.9 trillion annually by 2030 to meet the demand-side efficiency needs.
• The WBG's EE lending portfolio (FY15–24) reached $6.71 billion, with significant cost-effectiveness (0.63 US¢/kWh saved).

Appendices and Supporting Materials

• The report includes a list of boxes and tables that provide detailed insights into EE challenges, cost savings, financing models, and institutional functions.
• It references the RISE (Regulatory Indicators for Sustainable Energy) scores and the International Energy Efficiency Scorecard (2022) to illustrate regional and country-level trends in EE.
• The ESMAP (Energy Sector Management Assistance Program) plays a critical role in supporting the WBG's EE initiatives through technical and financial assistance.

Final Call to Action

The WBG calls for a unified and coordinated effort to scale up EE globally. By working together, governments, donor partners, and the private sector can unlock the full potential of energy efficiency and ensure sustainable, affordable, and secure energy access for all.
