This Master's thesis, submitted to the Department of Electronic Business at Middle East University in Amman, Jordan, investigates the influence of sustainable energy on business performance through advertisement, using the King Abdullah II Industrial City as a case study. The study aims to demonstrate and analyze the impact of sustainable energy usage on business outcomes, considering the role of advertising. The research involved data collection from 215 project managers across 25 companies using sustainable energy, employing a questionnaire to gather insights. Statistical analysis, including multiple regressions, was conducted to test the hypotheses. The findings reveal significant relationships between sustainable energy, business performance, and advertising variables. The thesis concludes with a discussion of results, recommendations, and implications for businesses, policymakers, and researchers, emphasizing the importance of sustainable energy practices and advertising strategies in enhancing business success. The study also suggests further research on the impact of sustainable energy and advertising on business performance.
