However, most studies and efforts have focused on developing policies that directly benefit the national electrical market, which may cause a lack of attention toward solutions that cater to low-consumption cases, such as residential and rural communities. Therefore, it is vital to consider the needs of these communities while developing policies and solutions to ensure that they also have access to reliable and affordable sources of electricity. This study analyzes the cost-effectiveness and technical performance of a hybrid renewable energy system (HRES) that can meet the power needs of low electricity-consuming households in a rural region of Guatemala. The proposed HRES comprises a hybrid photovoltaic-wind turbine-bio generator coupled to battery storage, which caters to the energy needs of a typical household in Alta Verapaz, a rural area in Guatemala with limited electricity access (64.61%). The research considers three scenarios: I) basic electricity needs for the household, II) increased electricity needs for cooking and water heating, and III) future electricity demand in 2050, considering the role of the renewable energy market. Based on Scenario I, the cost-effective solution is a PV system with a capacity of 5.39 kW and 29 kWh battery capacity, with a cost of energy (COE) of 0.893 $/kWh. In Scenario II, a hybrid solution consisting of a 2.46 kW PV system, a 2.20 kW bio-generator, and 16 kWh battery capacity o, results in a COE of 0.605 $/kWh. Scenario III suggests a hybrid system, including 7.90 kW of PV, 3.30 kW bio-generator, and 14 kWh battery to meet the expected energy demand in 2050. COE for this solution is estimated to be 0.297 $/kWh. Considering the declining costs of renewable energy technologies by 2050, the findings highlight that the proposed HRES can be an affordable solution for low-consumption scenarios such as off-grid areas in Guatemala.</p></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"88 ","pages":"Article 101762"},"PeriodicalIF":4.0,"publicationDate":"2024-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140893834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Decarbonizing the energy sector by deploying clean energy and reducing fossil fuels in the energy mix are essential steps. The study uses annual time series data from 1980 to 2021 and employs the ridge regression estimation technique to estimate a twice-differentiable transcendental production function, which approximates the second-order Taylor series to explore the potential for such decarbonization for France. The study finds that substitution possibilities exist between clean energy and fossil fuels, with substantial substitution possibilities coming from nuclear energy. Nuclear energy and renewables are found to be complements that can be deployed concurrently, but since nuclear energy already constitutes a significant proportion of clean energy for France, the study recommends increasing the proportion of renewable energy in the overall energy mix as the most plausible path to decarbonization.

The main findings are as follows. First, while the effect appeared statistically insignificant in the analyses of the industry as a whole, improving energy efficiency demonstrated a moderate effect for the agriculture industry in terms of research and development investment, fixed assets, and operating income when performing heterogeneity and moderation effect analyses. Second, a company's production dependence on labour is unfavourable to improving energy efficiency through ETS. Lastly, the adverse impact of labour dependence is more prominently observed in light industries, particularly in durable goods and agricultural sub-sectors. Therefore, this reaffirms that the key to increasing energy efficiency is to adjust Korea's ETS flexibly, considering the characteristics of each industry.</p></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"88 ","pages":"Article 101752"},"PeriodicalIF":4.0,"publicationDate":"2024-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140621852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
