The generation of energy from renewable sources is a fundamental aspect for the sustainable development of society, and several energy sources such as solar, biomass, biogas, and wind must be used to the maximum to meet existing needs. In Chile, there are villages that are off-grid. A real case study is presented in this research. To meet the needs of this village we have proposed a mathematical optimization model using a CPLEX optimizer to generate the necessary energy power while minimizing the cost of energy (COE). In this study, different scenarios have been evaluated with respect to the existing energy availabilities, for example, in different periods of the year, demonstrated in terms of economic costs, the viability of resources such as biomass and biogas, and the viability of the energy production of wind power given the associated high costs. Finally, the effect of the use of renewable energy in consideration of CO2 emissions is studied in our research.

Abstract Beneficiaries prefer renewable energy-based systems over grid-connected electricity. The cost of energy is viewed as the most influential factor while choosing renewable energy systems. Beneficiaries chose to stay linked with renewa­ble energy systems even when they received grid-connected electricity at a lower tariff.Net-metering and feed-in tariff mechanisms, as well as tax cuts and subsidies for renewable energy projects, could be the catalyst for fostering greater uptake of renewables in the electricity generation mix.

Abstract Due to high energy usage and power demand in industrial facilities, demand-side management (DSM) can simultaneously yield substantial energy cost savings for the facility and reduce the load on the power grid. There are many means of DSM, the most common being peak clipping, which is easily done with renewable energy systems and other power-generating devices. In this work, renewable energy systems (RESs) are critically reviewed and compared based on their application to industrial demand-side management (IDSM). Specifically, the RESs reviewed herein include photovoltaics, wind turbines, geothermal, and hybrid renewable energy systems. These devices are introduced, followed by a discussion of their advantages, disadvantages, and feasibility for use in IDSM. Most importantly, the reduction in the carbon footprint of power generation plants resulting from the use of RESs for IDSM is investigated. Comparisons are made based upon rated power, capital costs, O&M costs, levelized cost of energy, and the feasibility for use in industrial facilities. Using the values in the cost comparisons, the levelized cost of energy (LCOE) is derived for each device and used in a techno-economic analysis comparing the cost savings for the different RESs for a hypothetical plant.

AbstractWhile solar photovoltaics are projected to grow, major financial barriers exist that impede installation. Soft costs (human-driven costs) can account for over half of total project costs and are often simplified in typical models. We use the National Renewable Energy Laboratory's “Cost of Renewable Energy Spreadsheet Tool” to quantify uncertainty of three soft cost inputs and their influence on the output cost of energy using variance-based sensitivity indices. We then suggest how the development process and model can be redesigned to represent the complexities of this socio-technical system.
