Energy Security

The energy sector consists of thousands of electricity, oil, and natural gas assets that are geographically dispersed and connected by systems and networks. Therefore, interdependency within the sector and across the Nation's critical infrastructure sectors is critical. The energy infrastructure provides fuel to the Nation, and in turn depends on the Nation's transportation, communications, finance, and government infrastructures. The energy systems and networks cross the Nation's borders, making international collaboration a necessary component of the energy sector's efforts. Protecting and improving the resiliency of the energy sector in the face of both manmade and natural disasters is an ongoing effort that requires continued vigilance, contingency planning, and training. With partnership as the cornerstone of its overall strategy, the energy sector has numerous programs sponsored by public and private organizations that support the sector's security vision and goals. The energy sector will continue to implement effective protective measures as it assesses security needs, develops programs, and finds long-term solutions, including research and development. The Department of Energy's Office of Cybersecurity Energy Security and Emergency Response (CESER) provides technical expertise to help ensure the security, resiliency and survivability of key energy assets and critical energy infrastructure at home and abroad.
