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.

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.

Remote areas, where renewable energy systems can make their greatest impact, for the most part will not have data on the available resources. This is especially true in developing countries. Often, the designer has to estimate the resources either based on data available at similar or nearby locations or rely on qualitative information, which may be of the form :highly windy, highly variable, calm, mostly cloudy, etc. But, such information is only a snapshot and does not represent long term averages that are needed for planning. In present paper Micro Grid is planned for Makhla village in Amravati district as a rural electrification.

This article focuses on the need to develop alternatives to fossil fuels for present-day and future energy systems. The direction of energy research ought to be toward material science that can extend the life and lower the cost of renewable energy systems, rather than toward highly theoretical analyses that have over-the-horizon payoffs. Additionally, the planning for a smooth transition from fossil based to sustainable energy must include a side-by-side analysis of the economics as well as the energy return on energy investment (EROI) of each potential system. The EROI analysis would ensure the long-term viability of the technology, and the commercial analysis would show how much the system will cost and, thereby, provide an estimate of the money required for the installation in the transition period. The transition from the oil- and coal-based economy to a sustainably based future is not expected to be easy; however, taking advantage of the low-hanging fruit of conservation and energy efficiency will make that transition easier and much less painful.

Malaysia is one of the fastest emerging and developing countries in the world. To drive the economical workhorse, large amounts of power is required. The power demand has risen to 156,003 GWh per year in the year 2016, almost 30,000 GWh more than 5 years prior. Fossil fuels such as natural gas, coal, oil, and diesel have been the driving force powering Malaysia’s grids. However, these resources will not last forever, and they do harm to our environment. To counter this, renewable energy (RE) projects have been constructed all around Malaysia. This paper discusses on available and existing renewable energy systems (single/hybrid) in Malaysia and provides a comparison of their electricity generation capabilities. The renewable energy sources that are covered in this paper include Solar, Hydropower, Biomass, Tidal and Geothermal. At the moment, hydropower is the largest renewable energy producer, contributing to almost 15% of the country’s total energy generation. A lot of resources have been channeled towards the initiative of hydropower and it has definitely borne much fruit. This is followed by Solar Energy. Even though it is not as successful as hydropower, there is still a lot of avenues for it to grow in a tropical country like this. Malaysia is still relatively new in terms of power generation using biomass sources. There has been a gradual increase in the power generation using biofuels through the years and its future does look bright. Energy generation from wind, tidal, and geothermal sources has been rather challenging. Because of Malaysia’s geographical location, it experiences slow winds on average throughout the year. This has led to insufficient output for its financial input. Besides that, Malaysia also has relatively low tide, if compared to other Asian countries such as Indonesia and the Philippines. This contributed to the failure of tidal energy in Malaysia, but there have been signs of locations that can be suitable for this energy generation. Besides that, the country’s first geothermal power plant project failed due to a lack of preparation and discipline during the project’s execution. There is a high initial cost for geothermal projects, and the chances of failure are high if the necessary precautions are not followed. This could be one of the reasons why this branch of renewable energy has not been explored deeply.
