“…The Paris Agreement (COP21) of 2015 was the starting point for several countries in the world to be moved and begin to make efforts to limit the anthropogenic climate change that has alarmed the world due to its significant increase [1]. Many researchers have already provided sufficient guidelines for government decision makers to choose to change the energy matrix in their countries [2].…”

There is no doubt that the transition towards renewable energies is generating many changes on different continents, some with greater impacts than others, but the development that has occurred is recognized and widely accepted. The progress has been significant but it is necessary to analyze the roadmaps that have been proposed so far at the island level so that decision makers have sufficient tools to commit the much-needed economic resources to transform their energy systems into 100% renewable ones. These approaches are not simple and the hard work of the authors who have disseminated their research is recognized. The roadmaps are planned based on the energy potential available in the territories and the future energy demand. Within countries, it is important to increase the economic resources to allocate to investments in environmentally friendly renewable energies. In this review of 100% renewable smart systems on islands, the situation of the American continent, its challenges and its long-term approaches in the different geographical areas facing 2050 are analyzed. This article shows that research into the design of 100% renewable energy systems in scientific articles is fairly new but has gained more and more attention in recent years. In total, 175 articles published since 2002 were identified and analyzed. Many of these articles have a predominant focus on the electricity sector. As a general result, it has been determined that although there has been significant progress towards an orderly energy transition, this has not been consistent with the international agreements signed since the Paris Summit, which is a real challenge in complying with the new commitment of the COP28 of Dubai in tripling the participation of renewables.

“…Consequently, using fossil fuels in electrical power generation has led to significant environmental impacts, especially the emission of greenhouse gases such as CO 2 , which has become a critical issue of worldwide concern in the current scenario due to global warming [4]. To address this challenge and uphold the commitments made in the Paris Agreement (2015), several countries have set energy policies aiming at lowering annual greenhouse gas emissions and restricting the increase in global warming to a level significantly below 2 °C and actively striving to contain it within the range of 1.5 °C [5,6].…”

Gradient Boosting Approach to Predict Energy-Saving Awareness of Households in Kitakyushu

2023

View full text Add to dashboard Cite

This paper aims to develop a machine-learning model based on a gradient-boosting algorithm to predict the energy-saving awareness of households using a questionnaire survey and 11-month energy data collected from more than 200 smart houses in Kitakyushu, Japan. We utilize the LightGBM (light gradient boosting machine) classifier to perform feature selection for the prediction. By using this approach, we demonstrate that the key features are the standard deviations of electricity purchased between 8 a.m. and 9 a.m. and electricity consumed between 7 p.m. and 9 p.m. Next, by using k-means clustering we split the households based on the obtained features into three groups. Finally, by using statistical hypothesis testing, we prove that these three groups have statistically distinct levels of energy-saving awareness. This model enables us to detect eco-friendly households from their energy data, which may support energy policymaking.

“…Climate change and the recent energy crisis have raised the urgent need to increase the share of renewable energy sources (RESs) in the energy sector [1]. In this regard, in 2021, the Climate Change Conference (COP26) reaffirmed the role of RESs in achieving the Paris Agreement's goal of limiting the global average temperature rise [2]. Regarding energy security, in the REPowerEU plan, the European Union raised the renewable target for 2030 to 45% as a strategy to reduce energy dependency from Russia [3].…”

Promoting the Flexibility of Thermal Prosumers Equipped with Heat Pumps to Support Power Grid Management

The increasing share of renewable energy sources in energy systems will lead to unpredictable moments of surplus/deficit in energy production. To address this issue, users with heat pumps can provide support to power grid operators through flexible unit operation achieved via Demand Response programs. For buildings connected to low-temperature heating networks with ensured third-party access, further room for flexibility can be explored by investigating the production of surplus heat that can be sold to the network. A key aspect lies in the identification of the energy pricing options that could encourage such flexible operation of a heat pump by “thermal prosumers”. To this aim, the present study investigates the impact of ad hoc variations in the electricity purchasing price through discounts or penalties included in the “network cost” component of the price on cost-effective operation of a heat pump connected to the thermal network. To discuss the effects of different pricing options in terms of increased flexibility, an office building located in Italy and equipped with a high-temperature heat pump is adopted as the case study. A heuristic profit-oriented management strategy of the heat pump is assumed, and dynamic simulations are performed. The results indicate that at current electricity prices, the heat pump operation is profitable both when supplying the heat to meet the building’s requirements and when producing surplus heat for sale to the thermal network. In addition, it is revealed that the penalties applied to the electricity purchasing price are effective in encouraging changes in the heat pump operation strategy, reducing its average production (the building increasingly relying on buying heat from the network) and the associated electricity consumption by 46.0% and 79.7% in the “light” and “severe” local power deficit scenarios, respectively.
