Real Prospects for Energy Efficiency in the United States
Energy, which has always played a critical role in our country's national security, economic prosperity, and environmental quality, has over the last two years been pushed to the forefront of national attention as a result of several factors:
- World demand for energy has increased steadily, especially in develop ing nations. China, for example, saw an extended period (prior to the current worldwide economic recession) of double-digit annual increases in economic growth and energy consumption.
- About 56 percent of the U.S. demand for oil is now met by depending on imports supplied by foreign sources, up from 40 percent in 1990.
- The long-term reliability of traditional sources of energy, especially oil, remains uncertain in the face of political instability and limitations on resources.
- Concerns are mounting about global climate change-a result, in large measure, of the fossil-fuel combustion that currently provides most of the world's energy.
- The volatility of energy prices has been unprecedented, climbing in mid-2008 to record levels and then dropping precipitously-in only a matte of months-in late 2008.
- Today, investments in the energy infrastructure and its needed technolo gies are modest, many alternative energy sources are receiving insuffi cient attention, and the nation's energy supply and distribution system are increasingly vulnerable to natural disasters and acts of terrorism.
