U.S. Energy System Factsheet
Energy plays a vital role in modern society, enabling systems that meet human needs such as sustenance, shelter, employment, and transportation. In 2014, the U.S. spent $1.4 trillion on energy, or 8.0% of Gross Domestic Product (GDP). When spread over the population, annual costs were $4,374 per person. Environmental impacts associated with the production and consumption of energy include global climate change, acid rain, hazardous air pollution, smog, radioactive waste, and habitat destruction. The nation's heavy reliance on fossil fuels (primarily imported petroleum) poses major concerns for energy security. Potential gains in energy efficiency in all sectors may be offset by increases in consumption, leading to overall increases in energy use.
