This article analyzes the moral and scientific construction of the vole as a dangerous, yet intriguing rodent. Using a case study of An Economic Study of Field Mice (Genus Microtus) by David E. Lantz as example, this contribution discusses the role that agriculture comes to play in knowing the behavior of animals in natural history, and in turning wildlife into a matter of national government in the USA around 1900. In this setting, the Microtus is given the shape of a “small […] pest […that] inflicts enormous injury upon the crops of the country”. However, by granting field mice an important role in the agricultural development of the US Midwest, Lantz also qualifies the rodent as a capable agent deserving of scientific attention and political consideration. Thus, an animal otherwise perceived as repulsive and insignificant is transformed into an intricate being well worth dedicated study.

In this work, we present a technical and economic study of the solar powered street lighting system of a municipality in the south of Morocco. The state of the conventional street lighting system is first analyzed in a substation of street lighting. Then a sizing method is applied to the photovoltaic installation in the testing area. A financial study, by comparison between conventional and PV-based lighting, is carried out showing the feasibility of the PV street lighting.
