Temiz Enerji Sektörü, Teknoloji Sektörü ve Ham Petrol Arasındaki Yayılım İlişkisi

Öz

Küresel ısınmanın sonucu olarak ortaya çıkan iklim değişikliği yenilenebilir enerjiye diğer bir ifadeyle temiz enerjiye olan ilgiyi artırmıştır. Gelişen teknolojiyle birlikte verimliliğin artması ve maliyetlerin azalması sonucunda da yenilenebilir enerji tüketimi hızlanmıştır. Petrol piyasasının yenilenebilir enerjinin ikamesi olması, teknolojinin de yenilenebilir enerjinin önemli bir girdisi olması nedeniyle teoride yenilenebilir enerjinin her iki değişkenden etkilendiği düşünülmektedir. Yapılan çalışma ile teoride ileri sürülen bu görüş hem ortalamada hem de varyansta nedensellik ilişkisinin tespitine olanak sağlayan Hong (2001) yöntemiyle incelenmek istenmektedir. Temiz enerji sektörü, teknoloji sektörü ve petrol piyasası sırasıyla Willderhill Endeksi (ECO), ArcaTech Endeksi ve WTI tarafından temsil edilmektedir. 2004-2019 döneminin analiz edildiği çalışma sonucunda ortalamada temiz enerji sektöründen petrol piyasasına doğru, varyansta ise; petrol piyasasından temiz enerji sektörüne doğru Granger nedenselliğin olduğu tespit edilmiştir. Kappa-1 yöntemiyle belirlenen varyans kırılma tarihlerinin dikkate alınması sonrasında nedensellik ilişkilerinin varlığında herhangi bir değişim gözlemlenmemiştir. Elde edilen sonuçların araştırmacılara, politika yapıcılara ve yatırımcılara önemli bilgiler sunacağı düşünülmektedir.

Spillover Between Clean Energy Sector , Crude Oil and Technology Sector

Öz

Climate change resulting from global warming has increased the interest in renewable energy (clean energy). The consumption of renewable energy has accelerated as a result of increasing efficiency and decreasing costs due to the developing technology. In theory, renewable energy is thought to be affected by the oil market and technology sector, since the oil market is a substitute for renewable energy and technology sector is an important input of renewable energy. This view which is claimed in theory is aimed to be analyzed by the Hong (2001) method that allows the determination of causality both mean and variance. The clean energy sector, the technology sector, and the oil market are represented by the Willderhill Index (ECO), ArcaTech Index, and WTI respectively. As a result of the study that is span from 2004-2019, it has been determined that there is causality in mean from the oil market to the clean energy sector; and there is causality in variance from the clean energy sector to the oil market. After considering the variance breaking dates determined by the Kappa-1 method, no change was observed in the presence of causality. It is believed that the result obtained from the study, provide information to researches, policymakers and investors.
