National Energy Strategy reflects a National commitment to greater efficiency in every element of energy production and use. Greater energy efficiency can reduce energy costs to consumers, enhance environmental quality, maintain and enhance our standard of living, increase our freedom and energy security, and promote a strong economy.
(National Energy Strategy, Executive Summary, 1991/1992)
Increased energy efficiency has provided the Nation with significant economic, environmental, and security benefits over the past 20 years. To make further progress toward a sustainable energy future, Administration policy encourages investments in energy efficiency and fuel flexibility in key economic sectors. By focusing on market barriers that inhibit economic investments in efficient technologies and practices, these programs help market forces continually improve the efficiency of our homes, our transportation systems, our offices, and our factories.
