The Department of Homeland Security (DHS) on Friday announced its next set of cost savings initiatives aimed at making overall department operations more efficient.

The next installment of Efficiency Review Initiatives include standardizing new employee orientations, enhancing workforce management, implementing energy efficiencies in facilities and utilizing hybrid and alternative fuel vehicles when replacements are needed.

DHS also listed the savings from efficiency initiatives that are in progress. The Coast Guard expects $2 million in cost avoidance annually by restructuring maintenance and support schedules for 1,800 boats and $1.7 million by consolidating 10 support contracts into three, DHS said. The service also expects to avoid spending $450,000 over the next four years by converting lights for navigation buoys from incandescent signals to LED lanterns.

By recycling under used software applications, the Transportation Security Administration avoided $433,000 in new software purchases, DHS said.

Homeland Security Secretary Janet Napolitano launched the Efficiency Review Initiative in March.
