A number of bases have entered into third party contracts to do renewable energy projects. For example, in California, there's a large marine base called Fort Irwin that has done a number of solar projects and has worked with third party developers to do a solar project. We visited a navy facility near Seattle that was doing micro-grid on the base itself, a big energy management system and a micro-grid both for cost savings but also for resiliency and protection of critical infrastructure in the case of an interruption in the power supply.
One thing that Congress did in the early 2000s was to create, through statute at the Department of Defense level, an assistant secretary for operational energy to oversee the energy used by the Department of Defense.
