The protection of the environment and the simultaneous consolidation of sustainable development in the market are achievable, and constitute part of the foundation of European law. This law highlights their viability, in the area of financial mechanisms that support the production of renewable energy in an effort to address climate change. The harmony of these mechanisms, provided, for example, in Directive 2009/28/EC and its adoption by the Member States of the European Unon with the free movement of goods, is analyzed by the Court of Justice in the case of Ålands Vindkraft AB v. Energimyndigheten (C-573/12). In this case, the Couirt highlighted how compatibility among the climate, green energy production and the development of the market is a necessity. In this area, the European Commission has proposed to the Parliament and the Council a framework and package of measures, which they will implement together, based on their functions, in accordance with the provisions of European law.
