The Department of Energy (DOE) plays a critical role in maintaining the security of United States energy systems, which are foundational for national security, economic growth, public health, and safety. Essential energy services such as electricity, natural gas, and petroleum depend on the continuous operation of infrastructure and supply chains, which the DOE helps protect through various measures.
Among the DOE's responsibilities is managing the Strategic Petroleum Reserve to ensure energy supplies during disruptions. The department also invests in defense mechanisms against cyber and physical attacks targeting U.S. energy infrastructure. This protection is vital as all other critical infrastructure sectors depend on energy for secure and reliable operations.
The DOE conducts programs focused on the health and safety of energy sector workers and provides emergency response training and procedures to improve preparedness for potential energy disruptions. As the energy landscape evolves due to natural hazards, increasing demand, transportation electrification, and renewable energy integration, the DOE engages in planning efforts to sustain system reliability both in the short and long term.
