The European Energy Security: The Case of Natural Gas

The European Energy Security: The Case of Natural Gas Gas represents an important component of Europe’s energy architecture. Having limited gas resources at home, Europe needs to import much of the gas it utilizes. This arises a security issue, as importing large volumes of gas from a limited amount of countries (like Russia) exposes Europe […]
