Same Energy, More power: Accelerating Energy Efficiency in Asia

Energy efficiency is often defined as delivered energy service per unit of energy supplied into a system. Supply-side energy efficiency refers to decreasing energy losses in the supply chain, for improved performance in the production and delivery of electricity and heat. Demandside energy efficiency (DSEE) is achieved through consuming less energy for the same level of service, for improved efficiencies at the point of final energy use. DSEE, in particular, offers vast potential to meet regional energy needs in Asia, yet supply-side strategies tend to be prioritized as a focus of investment and planning. Over the past decade, the Asian Development Bank (ADB) has succeeded in quickly scaling up its investment in energy efficiency and the development of renewable resources within its developing member countries through ADB’s Clean Energy Program. This report examines prospects to accelerate lending and investment for DSEE in Asia, in light of trends that are driving energy use and policy and regulatory change in developing countries. Such efforts can help realize the full potential of DSEE as a least-cost, low-carbon resource for energy security, environmental protection, and sustainable and inclusive growth benefiting all Asians.
