Can Renewable Energy Mitigate Inflationary Pressures from Energy Imports? Evidence from Turkiye

The pith
Renewable energy reduces Turkiye's import-driven inflation more than its direct disinflationary effect.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
Energy imports and exchange rates raise inflation while renewable energy lowers it; the interaction term that captures renewables' ability to offset import-related inflation carries a larger negative coefficient than the standalone renewable energy variable, and this ordering holds in DOLS, FMOLS, and ARDL estimates.
What carries the argument
Interaction term between renewable energy consumption and energy imports, estimated in long-run models that incorporate structural breaks via Zivot-Andrews and Lee-Strazicich unit-root tests and Johansen/Hatemi-J cointegration.
If this is right
- Energy imports increase inflation while renewables decrease it.
- The mitigating role of renewables on import-driven inflation exceeds their direct effect.
- Exchange-rate depreciation adds upward pressure on prices.
- The ordering of effects is robust across DOLS, FMOLS, and ARDL specifications.
Where Pith is reading between the lines
- Similar import-renewable interactions may appear in other energy-importing emerging markets.
- Policymakers could prioritize renewables partly for their inflation-stabilizing side benefit.
- Future work could examine whether intermittency or grid costs weaken the observed interaction.
Load-bearing premise
The cointegration tests and long-run estimators identify the true relationships without large omitted-variable bias or endogeneity problems even when structural breaks are present.
What would settle it
A replication with post-2022 data or alternative break dates that yields an insignificant or positive coefficient on the renewable-energy-by-imports interaction term.

This study analyses the potential of renewable energy to reduce inflationary pressures arising from energy imports in Turkiye. Annual data for the period 1980-2022 are used in the analysis. In this study, unit root properties are examined using the Zivot-Andrews and Lee-Strazicich tests, both of which explicitly account for structural breaks. Cointegration is investigated via the Johansen and Hatemi-J cointegration tests. Long-run coefficients are subsequently estimated using the DOLS and FMOLS estimators. The robustness of the empirical findings is further assessed using the ARDL approach. In addition, an interaction term is constructed to measure the impact of renewable energy in alleviating inflationary pressures arising from energy imports. The results show that energy imports and exchange rate have an increasing impact on inflation, while renewable energy and the interaction term have a decreasing impact. DOLS, FMOLS, and ARDL results support each other. Moreover, in both models, the impact of renewable energy in mitigating inflationary pressures stemming from energy imports is stronger than the direct disinflationary impact of renewable energy.

Referee Report
Summary. This paper investigates whether renewable energy mitigates inflationary pressures from energy imports in Turkey using annual data 1980-2022. It applies break-adjusted unit root tests (Zivot-Andrews, Lee-Strazicich), cointegration tests (Johansen, Hatemi-J), and long-run estimators (DOLS, FMOLS, ARDL) that include an interaction term between renewable energy (RE) and energy imports (EI). The central claim is that EI and the exchange rate raise inflation while RE and the RE×EI interaction lower it, with the interaction-based mitigating effect stronger than the direct disinflationary effect of RE.
Significance. If the headline comparison holds after proper marginal-effect evaluation, the study adds to the literature on energy policy and inflation in import-dependent economies by documenting a quantitatively important interaction channel. The multi-estimator robustness and explicit treatment of structural breaks are positive features that would support policy relevance if the interaction result is shown to be statistically and economically larger than the direct RE coefficient.
major comments (2)
- [Results section / long-run estimates] The claim that the mitigating impact of renewable energy via the interaction term is stronger than its direct disinflationary impact (abstract and results section) requires explicit evaluation of the marginal effect β_RE + β_int × EI_t at observed EI levels (sample mean, median, or historical values) together with a Wald test of whether this marginal effect differs from β_RE. The reported DOLS/FMOLS/ARDL tables give only the separate coefficients; without these calculations the comparative statement is unsupported.
- [Econometric methodology and results] Structural breaks are detected in the unit-root tests, yet the long-run specifications (DOLS, FMOLS, ARDL) do not incorporate break dummies or regime-specific interaction terms. This leaves open the possibility that the relative magnitude of β_int versus β_RE changes across regimes, undermining the robustness of the headline comparison.
minor comments (2)
- [Abstract] The abstract omits variable definitions (units and sources for RE, EI, inflation, exchange rate), lag-selection criteria, and diagnostic statistics (serial correlation, heteroskedasticity, stability tests).
- [Tables and equations] Table and equation numbering should be added so that specific coefficient estimates and test statistics can be referenced unambiguously.

Referee: The claim that the mitigating impact of renewable energy via the interaction term is stronger than its direct disinflationary impact (abstract and results section) requires explicit evaluation of the marginal effect β_RE + β_int × EI_t at observed EI levels (sample mean, median, or historical values) together with a Wald test of whether this marginal effect differs from β_RE. The reported DOLS/FMOLS/ARDL tables give only the separate coefficients; without these calculations the comparative statement is unsupported.
Authors: We agree that the comparative claim in the abstract and results requires explicit marginal-effect evaluation to be fully supported. In the revised manuscript we will compute the marginal effect of renewable energy (β_RE + β_int × EI_t) evaluated at the sample mean, median, and selected historical values of energy imports. We will also report Wald tests of the null that this marginal effect equals the direct β_RE coefficient. These calculations and test results will be added to the results section and discussed in relation to the headline finding. revision: yes

Authors: We acknowledge that the long-run estimators do not include explicit break dummies. However, the Hatemi-J cointegration test already allows for structural breaks, which supports the validity of the estimated long-run relationship across the full sample. To directly address the concern about possible regime differences in the interaction effect, we will add the identified break dummies to the DOLS, FMOLS, and ARDL specifications as an additional robustness exercise in the revised version and report whether the relative magnitude of the interaction term versus the direct RE coefficient remains stable. revision: yes
Circularity Check
No circularity: standard empirical estimation on observed data
full rationale
The paper applies conventional time-series econometrics—Zivot-Andrews and Lee-Strazicich unit-root tests, Johansen and Hatemi-J cointegration, DOLS/FMOLS/ARDL long-run estimation, and an interaction term—to annual Turkish data 1980-2022. All reported coefficients and the comparative claim about the interaction versus direct renewable-energy effect are obtained by fitting these estimators to the observed series; no quantity is defined in terms of itself, no fitted parameter is relabeled as an out-of-sample prediction, and no uniqueness theorem or ansatz is imported via self-citation to close the argument. The derivation chain therefore remains independent of its own outputs and is self-contained against external data.
