The use of clean energy globally has certainly gained momentum since the 1970s with its many advantages over fossil fuels. Morocco, in turn, started exploiting this type of resource (except hydroelectric power) only in the 2000s. In addition, several authors have tried to analyze and verify the presence of a relationship between energy consumption and economic growth. In our study, we focused on the correlation between energy consumption by its two categories (fossil and renewable) and the economic growth of our country, Morocco. Using Eviews software, two tests were conducted to validate cointegration and causality, throughout the period 1990–2016. The ARDL test demonstrates a cointegration between GDP per labor engaged (GDP/L) as the economic growth indicator on one hand, and the three variables: Economic complexity indicator (ECI), total non-renewable energy consumption (TNRE), and total renewable energy consumption (TRE) on the other hand. The Toda-Yamamoto test proves unidirectional causalities from TRE to GDP/L, and from TNRE to GDP/L. Thus, we were able to confirm the growth hypothesis: Energy consumption (both fossil and renewable) has a positive impact on economic growth in the Kingdom of Morocco.
