This book presents the staggering details of the US Government’s national energy program. Over 150 energy-related program activities and 11 tax preferences address eight major energy activity areas: energy supply; energy’s impact on the environment and health; low-income energy consumer assistance; basic energy science research; energy delivery infrastructure; energy conservation; energy assurance and physical security; and energy market competition and education. At least 18 federal agencies, from the Department of Energy (DOE) to the Department of Health and Human Services, have energy-related activities.
