Artificial Intelligence (AI) plays an important role in modern society, supporting activities such as education, communication, and business operations. However, the rapid growth of AI has raised concerns about high energy consumption and environmental impact. Green Artificial Intelligence (Green AI) focuses on developing and using AI systems in an energy-efficient and environmentally responsible way. This study aims to examine the awareness, attitude, and adoption of Green AI practices among young adults aged 18–35. Primary data were collected from 120 respondents using a structured questionnaire with convenience sampling. Percentage analysis, ranking analysis, and chi-square tests were used for data analysis. The findings show that respondents generally have a positive attitude toward sustainable AI practices, but the actual adoption of Green AI is moderate. Lack of awareness, limited training, and high costs are identified as major barriers. The study suggests that increasing awareness and promoting energy-efficient technologies can improve the adoption of Green AI among young adults.
