Currently, the energy matrix worldwide relies on fossil fuels and the rate of consumption is increasing, so that the depletion of existing reserves is a reality that concerns everyone. The objective of this work was to propose a photovoltaic system on the roof of the kitchen-dining room building of the University of Moa, on which the energy that it is capable of delivering was determined. A simulation of it was carried out in the PV syst software. The results indicated that the installation generates 351 MWh per year with an installed capacity of 230 kW and the installation is made up of 851 photovoltaic modules occupying a useful area of 1.390 m2 .

Charging Strategy

Inhabited islands depend primarily on fossil fuels for electricity generation and they also present frequently a vehicle fleet, which result in a significant environmental problem. To address this, several governments are investing in the integration of Renewable Energy Sources (RESs) and Electric Vehicles (EVs), but the combined integration of them creates challenges to the operation of these isolated grid systems. Thus, the aim of this paper is to propose an Electric Vehicle charging strategy considering high penetration of RES. The methodology proposes taxing CO2 emissions based on high pricing when the electricity is mostly generated by fossil fuels, and low pricing when there is a RES power excess. The Smart charging methodology for EV optimizes the total costs. Nine scenarios with different installed capacity of solar and wind power generation are evaluated and compared to cases of uncoordinated charging. The methodology was simulated in the Galapagos Islands, which is an archipelago of Ecuador, and recognized by the United Nations Educational, Scientific and Cultural Organization (UNESCO) as both aWorld Heritage site and a biosphere reserve. Simulations results demonstrate that the EV aggregator could reduce costs: 7.9% for a case of 5 MW installed capacity (wind and PV each), and 7% for a case of 10 MW installed (wind and PV each). Moreover, the use of excess of RES power for EV charging will considerably reduce CO2 emissions

The search for energy alternatives from renewable and clean sources has been gaining prominence at the international level, due to the increased demand for energy and the future depletion of fossil fuels, coupled with the concern with environmental issues. The generation of electricity distributed from the use of biomass can contribute to the conservation of the environment, the diversification of the energy matrix, the national economic development, the generation of jobs in the agro-industry and in the distribution of clean energy, as a sustainable alternative. This chapter aims to present information related to the use of different residual biomass as an energy alternative for Brazil, with a focus on electricity generation, based on a bibliographic survey, where it is highlighted as the best sources of biomass for electricity generation in the country, observing the profitability and viability for logistics and national economy.

The increase in costs for electricity consumption has gone up, significantly affecting the economy of users, within the tariffs of residential users is the “DAC” rate (that means high consumption domestic rate). An economic analysis of electricity consumption rates indicates that, as of January 1st, 2019, the cost per kWh used in the “DAC” tariff corresponds to $ 5.121 MXN, which means that a “DAC” user pays more than 200% than a user 1C rate for each kWh consumed. For this purpose, a photovoltaic system has been designed for interconnection to the network, this system allows users to change from “DAC” rate to tariff 1C, and consequently will allow the reduction of these costs about the electric power service, this system can be installed in any yard, besides generating electricity, the photovoltaic products will be 2: a swing and a gazebo, with an installed capacity of 1.1 kWh, which will provide a rest and relaxation service.

Electricity is one of the most important needs of the community electricity shorttages are very disturbing human activities as well as the University of Riau Islands campus is very dependent on electricity supply from PLN, because this campus conducts tearning activities at night, the current energy is mustly fulfilled by fosil fuel energy such as petroleum, coal and natural gas but the supply of this energie is decreasing, PLN which as a supply of electricity is very dependent on fossil fuels so that PLN can at any time turn out blackouts on the campus of the University of Riau Islands very disturbed with the rilling blackout because the campus will be dark.there needs to be alternative energy at least illuminating as long as the electricity from PLN is on, this research and design is to build asolar electricity supply sistem to help temporary lighting in this design. PLTS is utilized as Alternative electrical energy to illuminatethe lobby of the Faculty of engineering Universitas Riau.Byusing50Wp solar cell panel,charge controller to maintain the stability of the sistem and 42 Ah batrtery, by using this sistem Dc lamps as a load of 54 Watt batrei capacitycan be lit during a blackout from the PLN.

The energy sector is an important factor that influences life quality and economic prosperity. Differences in infrastructure, technology and even in culture of each country make it imperative to include their own characteristics into energy analyses, making it necessary to identify the different types of sources of CO2 emissions and their magnitudes. The aim of this paper is to present a foresight analysis of the productive and energy matrices dynamics in Ecuador for the period 2016–2030 and to propose public policy that contributes to sustainable development. In a first stage, the research has an explanatory character, referring to construction of a model, which uses an extended variation of the Kaya Identity where the volume of CO2 emissions may be examined quantifying contributions of productive sectors activity, sectorial energy intensity, energy matrix, and CO2 emission features. Subsequently, the research acquires a predictive-experimental nature, using exploratory scenarios. That allows linking historic and present events with hypothetical futures. In consequence, driving forces of the scenario can be explained and analysed using quantitative modelling based on the Kaya Identity and qualitative narratives. Within this study two scenarios were built. The Business as Usual scenario, without modifying the structure of productive and energy matrices, and the Alternative scenario that seeks to reduce the consumption of oil derivatives in land transport, which consumes 50% of the country’s energy demand. The Alternative scenario, which promotes the use of biofuels, projects to reduce the CO2 emissions from 45.58 to 43.41 Mt of CO2 equivalent for 2030. The policy on biofuels in Ecuador is at an early stage. So, biofuels offer important opportunities: i) diversification of the energy matrix, ii) contribution to energy security, iii) promotion of the growth of the industrial sector, and iv) substitution of fossil fuels and mitigation of the greenhouse gas effects.

In the country and the world, it has become aware about the characteristics of non-renewable fossil fuels, and the high use of transport vehicles that use these fuels, in addition to industries and other sectors; these have boosted global research on alternative fuels, especially those derived from biomass. Peru in the change of its energy matrix has taken actions that allow it to increase the use of renewable energies such as biodiesel and bioethanol. Currently there are other proposals such as biorefineries that allow the greatest use of their natural resources. The investigations that have been carried out since 2010 have allowed us to have a technological contribution for the sustainable production of biodiesel in Peru.

This paper investigates the utilization of photovoltaic (PV) systems in a rural area electricity network. The Rural Area Electricity Company of Oman is planning to install a 304 kW PV system at the powerhouse of the Almazyonah network. Based on the available network data, a power flow model of the system under study was built and the system’s performance was studied. The location and installed capacity of the planned PV system were optimized based on loss reduction.
