Modeling Persistence Characteristics of Primary Energy Consumption from Renewable and Clean Resources: Considering Asymmetries and Structural Breaks

Tanrıverdi, Saliha
Yıldırım Kasap, Dilem
This study aims to analyze the persistence characteristics of share of renewables and clean energy (nuclear and renewables) in primary energy consumption for 5 countries, Austria, Brazil, New Zealand, Norway and Sweden over the period 1950-2020. The list of countries is selected based on their high level of primary energy consumption from renewables by 2020. We consider the importance of true specification of the deterministic components to better analyze the persistence properties. Changes in regulatory policies, implementation of new environmental laws, and potential market instabilities arising from some major events might result in structural breaks in the series. We employ a methodology that accounts for those breaks. Unlike the existing studies, our study allows for smooth and instant breaks together. Multiple unknown break dates are estimated by Bai and Perron (2003) methodology and smooth breaks are introduced in Fractional Fourier Functional Forms. To account for the sign and size asymmetry of responses of the series, which might arise from the break-even between adjustment costs and the burden of the shock, we further utilize Quantile Unit Root procedures. Bootstrap critical values are estimated accounting for the concerns arise from reduced sample sizes and non- standard distribution of the detrended series. By considering all factors affecting the stochastic properties of the series, we aim to provide reliable inferences regarding the long memory property of total and clean energy consumption, which will help policy-makers to better design and drive their policy objectives. Results show that especially Global Oil Crisis (1977) and policies towards easing climate change (2000s) had a significant impact on the countries decisions of energy mix. After accounting for the structural breaks, share of renewables and clean resources in the primary energy consumption are mostly stationary but show persistence for the lowest quantiles.

Modeling electrical energy production in Northwestern Cyprus based on solar and wind measurements
Yenen, Mehmet; Fahrioğlu, Murat; Sustainable Environment and Energy Systems (2015-1)
This thesis presents the solar and wind energy assessment and aims to model the link between measurement and electrical energy production from wind and solar resources in Northwestern Cyprus. The measurement systems were installed and the measurements from these systems were analyzed thoroughly to meet the expectations of this thesis. Existing mathematical models were used to calculate electrical energy production figures for wind and solar energy. A circuit based Photovoltaic (PV) model from the literature...
Forecasting Nigeria's energy use by 2030, an econometric approach
Asumadu-Sarkodie, Samuel; Owusu, Phebe Asantewaa (Informa UK Limited, 2016-01-01)
The study examines the causal nexus between energy use, environmental pollution, GDP per capita, and urbanization in order to forecast Nigeria's energy use by 2030. Employing a time-series data spanning from 1971 to 2012, a linear regression analysis is used to examine the causal relationship among the study variables and subsequently forecasted Nigeria's energy use with the ARIMA and ETS models. Evidence from the study shows that a 1% increase in energy use increases carbon dioxide emissions by 3%, while a...
Forecasting production of fossil fuel sources in Turkey using a comparative regression and ARIMA model
Ediger, Volkan S.; Akar, Sertac; Ugurlu, Berkin (Elsevier BV, 2006-12-01)
This study aims at forecasting the most possible curve for domestic fossil fuel production of Turkey to help policy makers to develop policy implications for rapidly growing dependency problem on imported fossil fuels. The fossil fuel dependency problem is international in scope and context and Turkey is a typical example for emerging energy markets of the developing world. We developed a decision support system for forecasting fossil fuel production by applying a regression, ARIMA and SARIMA method to the ...
National patterns of research output and priorities in renewable energy
Uzun, A (2002-01-01)
This paper attempts to compare the research Output and priorities of 25 major Countries in renewable energy research. The main objective is to assess the research priorities of the major countries in frontier areas subjects of renewable energy using some bibliometric measures based on renewable energy literature. Subjects of high activity and Subjects of low activity are identified for two time periods ( 1996-1997 and 1998 1999). Our findings, show that the output of publications including articles. reviews...
Clustering River Basins Using Time-Series Data Mining on Hydroelectric Energy Generation.
Arslan, Yusuf; Kucuk, Dilek; Eren, Sinan; Birtürk, Ayşe Nur (2018-09-14)
Hydropower is a significant renewable energy type with a considerable share in energy generation worldwide. As with the other common means of energy generation, hydropower is critical for the reliability and quality of electricity supply. Maintaining the reliability and quality of supply enables meeting the electricity demand of the loads adequately and efficient use of the energy resources, in addition to decreasing the related financial and environmental losses. In this paper, we target at the problem of ...
