Profili normativi sulla produzione di energia da fonti rinnovabili. Aspetti problematici sulle biomasse di orgine agricola.

This study offers in first place, a careful analysis of the legislation about renewable energy sources, and, in particurlar, energy production from them. The theme is developped on international level, through the origins of this recent branch of the law. Beginning from international policies about reductions of grennhouse gases - which are the real fulcrum for the development of renewable energy sources - communitary and national legislation on energy production from renewable energy sources is then analyzed. Successively, focus is given to problems related to some particular types of renewable energy sources, that is, biomasses of agricultural origin indeed. The correct legislational framwork is analyzed for biomasses and for their belongings to goods or wastes when used for energy production, also as a consequence of the so called “Nitrati Directive”. The problem is faced not only on communitary and national level, but also on local one.
