One of the greatest challenges currently facing our territory and country as a whole is that of energy. It is an issue that is set to become of increasing importance in the years to come and, as a result, requires that we start to plan and develop effective strategies for our society that allow sustainable ENVIRONMENTALLY-FRIENDLY growth. The motorway network is of central importance to modern-day life and economic wellbeing, enabling people and goods to move swiftly from place to place. It also represents, however, an undeniable source of pollution – both noise pollution and environmental. Photovoltaic noise barriers provide a means of reducing noise and environmental pollution caused by vehicle flow.
