The article deals with the issue of the energy efficiency in military camps. The military camps are mostly built during military deployments in case of exercises or missions. As different kinds of temporary structures are typically used to shelter large part of the camps’ facilities, the area of improvement for better energy efficiency lies mainly in the utilization of energy efficient devices, machines and pieces of equipment that are used by deployed personnel. The resulting lower energy consumption does not only bring lower financial and logistical burden to the military units but also contribute to the lower environmental impact of military activities. And ultimately, lowering energy use, especially fossil fuel, may result in cleaner environment and significantly affect health of deployed personnel. Overall, there are many benefits brought by energy efficient devices and equipment in several overlapped areas in military camps and their surroundings.
