Electricity -- the flow of electrical power -- is a secondary energy source, generated by the conversion of primary sources of energy, like fossil, nuclear, wind or solar.

Keeping the power flowing to American homes and businesses is a critical necessity for everyday life and economic vitality. The Energy Department works to keep the grid secure from cyber and physical attacks; partners with states and other stakeholders to plan more resilient infrastructure that can better withstand extreme weather events; and supports efforts to increase grid efficiency and energy storage as more renewable energy sources come online.
