Science and technology in the United States finish. For example, the British engineer Joseph Swan built an incandescent electric lamp in 1860, almost 20 years before Edison. But Edison's light bulbs lasted much longer than Swan's, and they could be turned on and off individually, while Swan's bulbs could be used only in a system where several lights were turned on or off at the same time. Edison followed up his improvement of the light bulb with the development of electrical generating systems. Within 30 years, his inventions had introduced electric lighting into millions of homes. Another landmark application of scientific ideas to practical uses was the
Edison Electric Institute such as the electric grid were included in the National Cyber Strategy. After Hurricane Maria hit the island of Puerto Rico in 2017, the federal government invested $3.2 billion into restoring the island's power grid. The Edison Electric Institute deployed Carlos D. Torres, a retired vice president at Consolidated Edison, to Puerto Rico to coordinate storm rebuilding of the power grid. Subsequently, Torres was appointed by Gov. Ricardo Rossello as coordinator for storm restoration. EEI supports the use of drones (unmanned aircraft systems, or UAS) by electric power companies to maintain electric grids and restore downed service. In July 2016,
