Renewable energy is a wide topic in environmental engineering and management science. Photovoltaic (PV) power has had great interest and growth in recent years. The energy produced by the PV system is intermittent and it depends on the weather conditions, presenting lower levels of production than other renewable resources (RESs). The economic feasibility of PV systems is linked typically to the share of self-consumption in a developed market and consequently, energy storage system (ESS) can be a solution to increase this share. This paper proposes an economic feasibility of residential lead-acid ESS combined with PV panels and the assumptions at which these systems become economically viable. The profitability analysis is conducted on the base of the Discounted Cash Flow (DCF) method and the index used is Net Present Value (NPV). The analysis evaluates several scenarios concerning a 3-kW plant located in a residential building in a PV developed market (Italy). It is determined by combinations of the following critical variables: levels of insolation, electricity purchase prices, electricity sales prices, investment costs of PV systems, specific tax deduction of PV systems, size of batteries, investment costs of ESS, lifetime of a battery, increases of self-consumption following the adoption of an ESS, and subsidies of ESS. Results show that the increase of the share of self-consumption is the main critical variable and consequently, the break-even point (BEP) analysis defines the case-studies in which the profitability is verified.

“…Also, developing an integrated model and assess the level of sustainable development of hard coal mining industry has been suggested [20,21]. Abandoned mine areas using renewable energy systems at the tailings dam of the abandoned Sangdong Mine of Korea is an example of a sustainable development project [22]. In general, mining operations cannot proceed with mining as in the past, since global expectations have changed the role of the business.…”

The Status of the Local Community in Mining Sustainable Development beyond the Triple Bottom Line

Abstract:Mineral products provide essential fuels and raw materials for industrialization and our daily life, but their influences on other aspects of life need to be taken into consideration. While the whole world benefits from mining's contributions, most of the resulting detrimental impacts on the environment and society fall on the local communities. The participation of the local community is one solution to decrease the risks from community-related problems. Subsequently, the requirements of mining sustainable development can be met. A literature review was conducted on mining sustainability and stakeholder participation, and the shortcomings of existing research and difficulties of further study were discussed in detail. This study covers a broad understanding of mining sustainability from a mining community's perspective. In addition, it offers a new mining sustainability scope based on the literature review. Besides the balance of economic, environmental, and social aspects, the mine owner and local community have to be engaged in the new mining sustainability scope. This literature review could improve community engagement and help mining companies to better understand local mining communities.

Abstract:Hourly irradiance values are essential data to reasonably estimate the electric power production (EPP) from a photovoltaic (PV) system. Worldwide monthly irradiance data are available from meteorological observation satellites; however, adequate hourly data are not widely available in developing countries or rural areas where PV systems are needed most. Aiming to supply such data, this study compared three different methods (i.e., sunshine hours mean, the SOLPOS algorithm, and the Duffie and Beckman algorithm) to convert the monthly accumulated irradiance data into hourly irradiance data. The monthly accumulated irradiance data at 11 sites in the United States and Korea, acquired from the National Renewable Energy Laboratory, were converted into hourly irradiance data by employing the three methods. The converted hourly data were entered into the System Advisor Model to estimate the monthly total EPP values (henceforth, EPPs) from the PV systems. Each estimated EPP value was compared with those analyzed from the measured hourly data (regarded as the reference values in this study). After considering the errors between the EPPs estimated from the converted hourly irradiance data and measured using the hourly irradiance data, the simulation results with identical PV capacities indicated that the SOLPOS algorithm was the most appropriate conversion method.
