In this systematic approach to energy issues in Greek law, the author begins with the administrative organization of the energy sector and then in turn considers natural gas, renewable energy sources, lignite, petroleum and electricity, examining pervasive legal factors è^' e.g., competition, environment, tax è^' individually in each case. He clearly describes Greek law (and European law where applicable) affecting such factors as administrative services, research, prospecting, mining, licenses, land use planning, documentation, intergovernmental cooperation agreements, undertakings, facilities, storage, pricing, procurement and sales, transportation, transmission, distribution, and supply.
