In recent years, the increasing interest for energy efficiency has multiplied the number of players and the issuing of legislative documents, so the very notion of “efficiency” has taken different meanings in a more or less wide range of definitions, sometimes overlapping between them. These definitions often evoke different concepts such as “energy saving,” “rational use of energy,” “efficient use of resources,” “reduction of consumptions,” etc., in an amalgam shadowed by ambiguous interpretations. This paper proposes a clarification of the different expressions by defining their functional and conceptual boundaries and interrelationships, focusing the attention on the energy aspects, and leaving out other dominions that might govern or accompany that variable, such as, sustainability, competitiveness, economy, etc. The issue is not merely lexical or taxonomic. In fact, the strict definition of a concept defines its area of interest, and the decision-maker, when issuing a measure, should choose from his portfolio of available tools only those consistent with the involved domain.

The energy sector is vital to efforts to combat climate change as well as achieve economic development. The economy of many Middle East and North African (MENA) countries, such as Algeria, Iran, Qatar, Saudi Arabia, is completely based on hydrocarbons which represent the main source of the state revenue. Investing in renewable energy and efficiency is a winner strategy, allowing both to ensure the necessary availability of energy to cover the country’s domestic energy demand and to make more resources available for export to guarantee the state earnings. Renewable sources can be a solution for a transition to a more sustainable economy and a response to the economic stability of these countries affected by the volatility of oil prices. Such a strategy is reflected in improving the attractiveness of foreign investment in the renewable energy sector. Focusing on Algeria, in this article, we analyze the link between the Algerian economy and energy, underlining the current weakness. This work is partially based on the research financed by the meetMED project (WP 3.1) on barriers for domestic and international investors in the energy sector of Algeria.
