The entire world, especially the United States, is in the midst of an energy revolution. Since the oil embargo of 1973, individuals, corporations, and other organizations have found ways to economically reduce energy use. In this book, Jim Sweeney examines the energy policies and practices of the past forty years and their impact on three crucial systems: the economy, the environment, and national security. He shows how energy-efficiency contributions to the country's overall energy situation have been more powerful than all the increases in the domestic production of oil, gas, coal, geothermal energy, nuclear power, solar power, wind power, and biofuels. The author details the impact of new and improved energy-efficient technologies, the environmental and national security benefits of energy efficiency, ways to amplify energy efficiency, and more. Energy Efficiency: Building a Clean, Secure Economy reveals how the careful nurturing of private- and public-sector energy efficiency-along with public awareness, appropriate pricing, appropriate policies--and increased research and development, the trends of decreasing energy intensity and increasing energy efficiency can be beneficially accelerated.
