Renewable energy technologies can enhance homeland security, according to Richard Truly, director of the U.S. Department of Energy’s (DOE’s) National Renewable Energy Laboratory (NREL).

Speaking at the National Press Club last week, Truly noted that wind, biomass, geothermal, and solar energy sources can reduce U.S. reliance on foreign oil, thereby bolstering U.S. energy security. But they also serve to protect the country’s energy infrastructure from attack.

“Renewable energy technologies — particularly when deployed as a distributed energy resource — can play a vital role in securing our energy infrastructure,” said Truly. “The more energy efficient we are, the more energy we get from sustainable, domestic resources, the less pressure we have on our energy infrastructure and the less vulnerable we are to disruption.”
