AbstractMarine renewable energy (MRE) is in the early stages of contributing to the energy portfolios of the United States and many other nations around the world. Although many MRE developers are designing devices that will harvest energy to contribute to the electrical grid from waves, tides, and ocean currents, a number of other promising maritime markets could be supplied with MRE power at sea. These maritime markets are often less price sensitive, have fewer options than utility-scale electricity markets, and can handle some degree of intermittency. Some of the promising maritime markets that could benefit from co-located power generation include ocean observation nodes, underwater recharge of autonomous vehicles, desalination of seawater for remote coastal areas, offshore aquaculture, shoreline protection and electricity generation, providing electricity and freshwater following coastal emergencies, providing power to islanded and isolated communities, powering and cooling nearshore underwater data centers, recharging of electric surface vessels, and personal charging of electronics. Pairing of MRE power generation with these and other maritime markets is in the early stages, but the potential for synergy and growth of MRE coupled to these markets is promising.

Power generation through renewable sources is an effective alternative to mitigate climate change as its environmental impact is lower compared to fossil fuels. However, socio-economic problems are constant in sites where power plants are installed, especially in developing countries. In this paper, an innovative methodology was developed to assess the suitability of electricity generation through solar, wind, and biomass energy. Unlike most studies found in scientific literature, this work considers social, environmental, and economic aspects as key to determine the suitability of energy projects. First, we carried out a comprehensive analysis on social acceptance and resilience towards renewable energy and the conditions for communities to benefit from these projects; then, we analyzed the availability and capacity of renewable energy sources in Mexico, as a case study. Next,  a set of indicators related to the three pillars of sustainability was developed to assess the conditions of each place with the best renewable resources in the country. The life cycle and capacity factor of each technology were also considered. Lastly, a mathematical model was developed to determine the most suitable locations and technologies for power generation. The results show a trend towards the states of northern Mexico, especially those bordering the United States, as the most viable for electricity generation. The most appropriate technology is wind energy. Finally, Oaxaca, the state with the best wind resources and current leader in wind power generation in Mexico is, by contrast, the least viable state for wind generation, as has been later confirmed by scientific evidence, as wind facilities are associated with severe socio-cultural and economic damage in host communities in this state.

The use of Hybrid Power Generation Systems through renewable sources has been gaining prominence, since it is a way to reduce the dependence on fossil fuels, contributing to the reduction of pollutant gas emissions to the environment. Due to the higher operational complexity, the multiplicity of options and constant improvement of these units, how to optimize these systems is still a subject of present studies. Considering the attention that this topic has received from the academic community, the challenges for mapping and identifying the relevant literature, this article provides a macroscopic view of the scientific literature on the Optimization of Hybrid Renewable Energy Systems (HRES) for energy generation, through analysis bibliometric. The research was developed using the Web of Science database, obtaining a total of 439 articles between 2010 and 2020, where the results were interpreted through the VOSviewer software. The results showed that the number of related publications is gradually increasing, with India as the leading country. The University of Malaya is the institution with a higher number of registers, with 14 entries. Most publications fit into the “Energy Fuels” category, with the magazines “Renewable Sustainable Energy Reviews” and “Renewable Energy” as the most influential in terms of the number of publications, as well as the United States and China are the countries with most research collaboration. Besides, the most cited articles and the recurrence and distribution of keywords indicate the future directions of research. In short, this study contributes valuable information to researchers on the topic.

This article explains the process of cofiring biomass with coal that could be a relatively inexpensive way to extend energy resources in the United States. While biomass-fired plants have been a part of the scene for some time, they are relatively small, 25–50 MW, and often address specialized local conditions. In California, they are helping to reduce air pollution by replacing the open field burning of agricultural residue. Adapting coal-fired units to cofire biomass requires additions and modifications, but compared to starting a new plant from scratch, it is a relatively low-cost, low-risk method to add renewable energy to the plant fleet. In a cofiring application for a pulverized coal plant, biomass can replace 20% of the coal being used. With cofiring, power generation is not dependent upon biomass, so there is a lower risk of technology entry than with other renewable energy options. Biomass can be used when supplies are available.

Abstract Using fossil fuels as the primary way to generate electricity causes a significant effect on the environment. In 2019 more than 64% of the electricity in the United States of America was generated using fossil fuels resources, while renewable energy (RE) resources contributed to only 17% of the U.S. electricity generation for the same year. Due to the complex terrain distribution of many states in the U.S., a massive opportunity of utilizing RE resources in rural and remote areas can reduce the cost of electrical grid installation for such areas. In this study, a typical residential building with an average energy consumption of 30.25 kWh/day with a peak of 5.34 kW was considered a case study in each state to optimize a hybrid RE system and find the best alternative electrical grid system. This study presents the best configuration between Solar and Wind energy with different types of energy storage. It was found that the photovoltaic (PV) - diesel generator with battery best serves in all states. The daily radiation and diesel prices substantially affect the Levelized Cost of Energy (COE) values in each state.

Abstract Achieving an economy-wide net-zero greenhouse gas emissions goal by mid-century in the United States entails transforming the energy workforce. In this study, we focus on the influence of increased labor compensation and domestic manufacturing shares on (1) renewable energy technology costs, (2) the costs of transitioning the U.S. economy to net-zero emissions, and (3) labor outcomes, including total employment and wage benefits, associated with the deployment of utility-scale solar photovoltaics (PV) and land based and offshore wind power. We find that manufacturing and installation labor cost premiums as well as increases in domestic content shares across wind and utility-scale solar photovoltatic supply chains result in relatively modest increases in total capital and operating costs. These small increases in technology costs may be partially or fully offset by increases in labor productivity. We also show that solar and wind technology cost premiums associated with high road labor policies have a minimal effect on the pace and scale of renewable energy deployment and the total cost of transitioning to a net-zero emissions economy. Public policies such as tax credits, workforce development support, and other instruments can redistribute technology cost premiums associated with high road labor policies to support both firms and workers.

The Impact

A tanulmány arra keresi a választ, hogy a megújuló alapú áramtermelők támogatása csökkentőleg hathat- e a villamos energia nagykereskedelmi és kiskereskedelmi árára. Ez utóbbi tartalmazza a megújulók támogatásának összegét is. Számos elméleti cikk rámutatott arra, hogy nemcsak a nagykereskedelmi árak, hanem a kiskereskedelmi villamosenergia-árak is csökkenhetnek a drágább, megújuló alapú áramtermelők támogatása révén. A tanulmány során egy villamosenergia-piacokat szimuláló modell segítségével modellezi a szerző, hogy a különböző mennyiségű szélerőművi és fotovoltaikus kapacitás támogatása hogyan hat a magyarországi nagykereskedelmi és kiskereskedelmi árakra. _____ Impact of the Hungarian renewable based power generation on electricity price The aim of this paper is to answer the question whether the support of renewable power generation could decrease the wholesale and retail electricity prices. The latter one includes the support of renewables. Several studies point out that not only the wholesale, but the retail electricity prices could decrease when supporting the more expensive, renewable power generation. A model, which simulates the electricity markets, is used in order to analyse the impact of different level of wind and photo voltaic power generator support fee on Hungarian wholesale and retail electricity prices.

AbstractMarine renewable energy (MRE) encompasses the harvest of energy from the movement of ocean waters in the form of either currents or waves, as well as temperature and salinity differentials. To date, most MRE development has focused on utility-scale electrical grid generation, but a growing body of work focuses on non-grid applications in the blue economy where MRE could provide power on-site and at the scale needed for specific maritime sectors. One of the blue economy sectors with promising applications for MRE is ocean observations using both mobile and stationary platforms. This paper documents the steps and results of engaging with experts across the myriad ocean observation platforms and capabilities to inform five use cases. These use cases include descriptions of specific ocean observation applications performing measurements of high societal value (e.g., data for weather forecasting and tsunami detection) that closely resemble specific sensing systems and, in most cases, are placed in a particular area of the ocean. Rapid resource assessments (i.e., first-order estimates) were performed at these locations to determine the suitability of marine and other renewable energy sources. From the information gathered so far, MRE has significant potential to enable improved ocean observation missions, expand ocean observing capacity, and develop as an industry in parallel with the needs of our changing oceans.

Alternative Investment

Native American reservations are among the most economically disadvantaged regions in the United States; lacking access to economic and educational opportunities that are exacerbated by “energy insecurity” due to insufficient connectivity to the electric grid and power outages. Local renewable energy sources such as wind, solar, and biomass offer energy alternatives but their implementation encounters barriers such as lack of financing, infrastructure, and expertise, as well as divergent attitudes among tribal leaders. Biomass, in particular, could be a source of stable base-load power that is abundant and scalable in many rural communities. This case study examines the feasibility of a biomass energy plant on the Cocopah reservation in southwestern Arizona. It considers feedstock availability, cost and energy content, technology options, nameplate capacity, discount and interest rates, construction, operation and maintenance (O&M) costs, and alternative investment options. This study finds that at current electricity prices and based on typical costs for fuel, O&M over 30 years, none of the tested scenarios is presently cost-effective on a net present value (NPV) basis when compared with an alternative investment yielding annual returns of 3% or higher. The technology most likely to be economically viable and suitable for remote, rural contexts—a combustion stoker—resulted in a levelized costs of energy (LCOE) ranging from US$0.056 to 0.147/kWh. The most favorable scenario is a combustion stoker with an estimated NPV of US$4,791,243. The NPV of the corresponding alternative investment is US$7,123,380. However, if the tribes were able to secure a zero-interest loan to finance the plant’s installation cost, the project would be on par with the alternative investment. Even if this were the case, the scenario still relies on some of the most optimistic assumptions for the biomass-to-power plant and excludes abatement costs for air emissions. The study thus concludes that at present small-scale, biomass-to-energy projects require a mix of favorable market and local conditions as well as appropriate policy support to make biomass energy projects a cost-competitive source of stable, alternative energy for remote rural tribal communities that can provide greater tribal sovereignty and economic opportunities.
