Energy Efficiency

Energy efficiency is defined as economic investments in energy generation, delivery and end-use equipment, facilities, buildings, and infrastructure that deliver higher useful energy outputs or services (e.g., lighting, heating, refrigeration, pumped water) with lower consumption of energy and reduced emission of greenhouse gases.

Energy use in Asia and the Pacific has increased rapidly over the past 30 years, reflecting the region’s growing productivity and wealth. With greater wealth, countries seek higher energy supplies, which enable them to implement large infrastructure projects, improve irrigation systems, and undertake other significant measures to promote productivity growth. However, most countries in Asia and the Pacific use energy inefficiently, which increases fuel imports and the burden on national economies.
