Abstract:

Countries consume large amounts of coal, oil, and natural gas due to the energy structure dominated by fossil fuels worldwide. For this reason, the rate of renewable energies in countries or country groups in general is below the global average level. In this study, we aimed to test the stationarity of renewable energy consumption for Brazil, Russia, India, China, South Africa, and Turkey (the BRICS-T countries), which are in a rapid development. For this purpose, Bozoklu et al. (2020) used the fractional frequency Fourier unit root test. Annual data on renewable energy consumption covering the period of 1990–2015 have been accessed from the official database of the World Bank. According to the results obtained, it has been found that the renewable energy consumption of China, one of the BRICS-T countries, is stationary and that other countries contain unit root.
