This study aims to investigate the impact of oil, gas and electricity consumption on agricultural, industrial, and transportation output. Data from 1990 to 2014 were analysed using several tests, namely FMOLS, DOLS, PMG and MG. The results show that an increase in energy consumption can help boost economic growth in the long run in Malaysia. Specifically, all energy types (oil, gas, and electricity) can affect aggregate output in the long run. In the short run, this study found that oil consumption plays an important role in determining aggregate output. However, this study found that other energy types do not have a significant effect on aggregate output in the short run. Gas consumption can influence output in the industrial sector and transportation sector in the short run. Electricity and oil consumption does not play an important role in determining output in all sectors in the short run. These findings are important to formulate policies to reduce environmental degradation.
