This study estimates the threshold level of clean energy and investigate its implications on energy efficiency and income per capita from world’s top ten energy consumers for the period of 1960-2017. Countries include Brazil, Canada, China, Germany, India, Japan, Russia, South Korea, France and United States, accounting for more than 60 % of world’s primary energy consumption. Results show that the correct mix of clean energy drives overall energy efficiency in all countries. Further results confirm that threshold levels of clean energy exist in the relationship of energy efficiency and income per capita. In particular, we find that increasing the share of clean energy (below the threshold level) increases energy efficiency in Brazil, Germany, India, Russia and South Korea. The effects of clean energy above its threshold levels turns stronger in all countries except Brazil, Canada and Russia. This has been noted that the above three countries have witnessed sluggish growth in clean energy share particularly above the threshold levels. In the similar settings result show that below the threshold levels of clean energy, income per capita significantly increases with increasing the energy efficiency (decreasing energy intensity) from all countries except China, Japan and Korea. This might be due to the dominant effects of non-clean energy share in total primary energy consumption in the above countries. However in cases of China and Korea above the threshold levels of clean energy, the impact of energy efficiency turns more prominent in accelerating income per capita. The similar results have been observed in all other countries except Brazil where income per capita appears insignificant with energy intensity predominantly above the threshold levels of clean energy.
