Department of Transportation (DOT), General Services Administration (GSA), Council on Environmental Quality (CEQ), and the White House. Grid security The energy grid is a complex, interconnected network of generation, transmission, distribution, control, and communication technologies. Any of these can be damaged by either natural events or malicious attacks such as cyber or physical attacks. The electric power industry has engaged with a series of initiatives meant to protect the energy grid from these threats. The industry collaborates with the National Institute of Standards and Technology, the North American Electric Reliability Corporation, and federal intelligence and law enforcement agencies. On September 20, 2018, EEI announced that it supported the Trump Administration's unveiled National Cyber Strategy. The protection of critical infrastructure such as the electric grid were included in the National Cyber Strategy. Hurricane Maria 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. Unmanned aircraft 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, Congress passed legislation (H.R. 636) that "includes provisions supporting electric power companies utilizing unmanned aircraft systems (UAS) for energy grid maintenance and service restoration." Renewable energy Partnership with pro-environment group In February 2018, EEI and the Natural Resources Defense Council (NRDC), a non-profit international environmental advocacy group, released a joint statement outlining 21 policy priorities on which both organizations would work together to advance clean energy. Both organizations said the recommendations are designed to “accelerate the clean energy transition; promote investment in smarter energy infrastructure, while ensuring affordable and reliable electricity; and facilitate collaboratively developed rate design and regulatory reforms that accommodate rapid technology change and evolving customer expectations.” Advocacy for changes to homeowner solar panel policies Between 2011 and 2017, rooftop solar panel installations had "explosive growth — as much as 900 percent by one estimate." But by 2017, the growth stopped. Saturation in certain markets, such as California, and financial problems at several of the top solar panel makers are the main factors that caused the decline in growth. But, according to the New York
