New renewable energy sources can play a crucial role in promoting the environment and the transition to a low carbon economy. As soon as the production system has been installed, solar, wind and hydropower not only produce minimal emissions, but they also contribute to poverty reduction by promoting access to energy in underserved areas. However, the question needs to be asked: how is it possible to fully exploit the potential of renewable energy? Accordingly, this article presents a critical discussion of the context of the debate on alternative energies; it also scans the potential of renewable technologies and the possibility of integration in building. Attention will be given to applications related to buildings. We will discuss the possibility of integrating of hybrid collectors to produce energy to buildings. The idea is to integrate in a simple device a Photovoltaic module and a thermal solar collector, to create the hybrid solar collector (PVT). This hybrid collector can simultaneously produce a both electric and thermal energy. The aim is to increase the electrical efficiency and improve the thermal performance of the collector .We present the results obtained from our experimental study will analyze the data collected by studied collector.
