Abstract: The economic growing and technological development brought advantages to society. However, the adoption of the sustainable development is necessary so the future generations will not be compromised. In this way, the present work has as its objective presenting a bibliographical review about roads, bridges and bike lanes that generate renewable energy. The photovoltaic panels are very important to generate energy on the roads and, as an example, the acoustic barriers on the roads can be exchanged or implemented with photovoltaic panels to maintain the function of sound barrier and of generator of electric power at the same time. Another way of generating renewable energy are bike lanes, in the Netherlands, as an example, it is utilized a special concrete, superimposed by a layer of highly resistant glass with photovoltaic cells, so the installed floor can convert sunlight into energy. The piezoelectric energy can also generate energy in bike lanes using a pressure-sensitive floor with friction from bicycle tires. When it comes to bridges, a project developed in Italy intends to place solar panels and wind generation turbines in a bridge as a way of generating energy, generating around 40 million kW/h in one year. The proposal of this bridge is to fulfill empty spaces among the existing pillars on the bridge to integrate the system of wind turbines in the structure. It can be concluded that, throughout time, the renewable energies have been standing out and civil construction has shown an important role in this sector, presenting technological solutions and taking advantage of spaces in relation to the implantation of roads, bridges and bike lanes.Key words: Sustainability. Renewable Energy. Photovoltaic Plates. Piezoeletric Energy. Wind Energy.
