Approximately 1,700 military personnel from Nato member states have commenced the alliance's annual logistics interoperability exercise at Bakony Combat Training Centre near Veszprem, Hungary.
The 11-day exercise, code-named Capable Logistician 2015, involves input from 30 experts from defence agencies and research institutes, and will validate more than 50 pieces of equipment.
The technologies include micro grids to enhance a camp's energy management, renewable energy sources, such as wind and solar power, insulation against heat and cold, low-energy technologies for water purification, LED lights, as well as small portable fuel cells for Nato soldiers.
The exercise scenarios will test how the participants respond to power cuts, diesel and water contaminations, as well as generator breakdowns.
Nato Emergency Security Challenges Division assistant secretary general Ambassador Sorin Ducaru said: "Nato Smart Energy is about empowering the soldier of the future and an important missions enabler for the modern military.
"It reduces cost and risks of military operations, as well as the environmental footprint of the military."
Supported by Nato's Science for Peace and Security Programme, the drills focus on evaluation of a broad spectrum of energy-efficient solutions to help cut down cost while boosting interoperability and military effectiveness.
Nato will analyse how equipment using different energy-efficient technologies interacts with each other.
The long-term goal of the exercise is to introduce technologies capable of lowering the fuel consumption by soldiers deployed on military operations.
Exercise Capable Logistician 2015 is scheduled to conclude on 19 June.
Initiated in 2011, Nato's Smart Energy programme seeks to augment the energy efficiency of allied armed forces through varied means, such as the increased use of renewable energy, and better energy management.
