The European Union is striving to improve the European energy market by being more coordinated, as it is no longer possible to act in isolation in a united Europe. Large-scale renewable energy production requires an interconnected European energy market if the objectives set out in the Energy and Climate programme adopted in 2009 are to be achieved. The aim of this work is to determine how the rules of European law on legal standardisation in energy matters and the fight against global warming are affected. The development of non-carbon dioxide energy is in line with the objectives set by the European Union, which relies in this area on regions and no longer on the countries themselves that are not always in a position to implement the ambitious targets set. Energy continues to depend in most cases on the strength of states and European competence is limited. The European Union is mainly involved in coordinating and supporting national policies, within the framework of the provisions relating to trans-European networks and in the framework of environmental policy. In principle, measures relating to the choice of each country between different energy sources and the general structure of its energy supply were adopted unanimously. Particular attention was paid to comparing the French legal rules applicable to the development of renewable energy sources, adaptation to renewable energy sources of environmental law and urban planning and the importance of supervision, with European legal standards for regulation.
