Special Issue Information

Dear Colleagues,

In recent years, the energy issue has been playing a fundamental role in terms of environmental sustainability and the competitiveness of businesses. In fact, the triad of EU objectives to 2030 provides for the 40% reduction of greenhouse gas emissions compared to 1990, the achievement of the target of 32% of penetration of renewable energy sources (RES) in energy consumption, and the 32.5% reduction in consumption as a goal for energy efficiency.

This Special Issue aims to consider, within the energy communities, the optimization of energy systems, passing from the management of the production of electrical and thermal energy, their storage, and their distribution through electricity networks and district heating and cooling networks. The contributions to this Special Issue are expected to usefully integrate the existing scientific literature, highlighting the consequence of these innovations and referring to the new reality of the energy communities, emerging from the provisions of the European Commission. At the same time, the emerging interest of the political administrators for the energy communities is producing a new regulatory context, where the theoretical results of the optimal energy distributed production and allocation can be tested in the real world. Papers dealing with this kind of real applications or presenting projects where full-scale tests are planned for the near future are also welcome.

Abstract
Since the price for residential heat (RH) from district heating system in South Korea is regulated by the government rather than being freely determined in the market, it is difficult to estimate the demand function for RH properly using the distorted market data. [...] Read more.
Since the price for residential heat (RH) from district heating system in South Korea is regulated by the government rather than being freely determined in the market, it is difficult to estimate the demand function for RH properly using the distorted market data. Thus, undistorted data on price and demand are required in obtaining the demand function. This article tries to estimate the demand function for RH by applying the price sensitivity measurement (PSM) technique, with some variation, and then use this to obtain information about the price and income elasticities. To this end, in the PSM survey 1000 households were first asked about their consumption of RH and their expenditure on that consumption and then asked about how much they would lower their demand for RH in response to four hypothetical increases in the price for RH (10%, 20%, 50%, and 100%). Thus, five sets of price and consumption of RH were available for each household. The demand function for RH was estimated using a total of 5000 observations. The price and income elasticities were estimated with statistical significance to be about −0.478 and 0.033, respectively. These values can be utilized in decision-making and/or policy-making related to RH management. Full article
