Abstract The electric energy matrix in Brazil mostly comprises energy from hydroelectric power plants, approximately 60.8%. This large participation presents some vulnerability in periods of drought and often the country's electric energy matrix is complemented by the use of other energy sources, such as thermoelectric. Even though it is currently among the largest onshore wind power producers in the world, Brazil has not yet started developing this energy source in the offshore segment. However, this study shows that offshore wind energy can be a complementary energy source for the country's electric energy matrix, and thus replace other energy sources which have more impact on the environment. Therefore, this study sought to develop a methodology that can be easily replicated using free access tools, aiming to contribute to the development of offshore wind technology and future research in the country. The results show a large production of offshore wind energy in the southeastern region of Brazil. The "Cabo Frio 2" data collection point presented the highest annual production of offshore wind energy. However the study opted for the "Arraial do Cabo-A606" collection point located in the state of Rio de Janeiro and at ocean depths that can be reached by fixed foundations.

Thermal Power plants are the major source of generation of electricity for any developing country. The thermal power plant has serious impacts on land, soil, air and various social impacts the thermal power plant are also said to emit large amount of mercury and generate large quantity of fly ash which destroys the surrounding environment. These plants also consume a large amount of water. Due to these problems they require a proper Environmental impact assessment before commencement of the proj...

The operation of hydroelectric plants in Brazil depends on the hydrological regime, which is subject to significant seasonal fluctuations and faces critical levels of storage in certain periods. Hydropower accounts for 66% of the country׳s generation and poses a challenge for the stabilization of the grid in the mid and long terms. Usually, such fluctuations are complemented by conventional sources (thermo power). Studies have shown, however, that wind power can assist hydroelectric power genera...

It has been globally recognized that the harvesting of renewable energy is of considerable importance for the achievement of sustainable development. As for Hong Kong, one of the most densely populated cities, the shortage of indigenous fossil sources has inevitably resulted in excessive dependence on external energy sources. Nevertheless, in consideration of the reduction of fossil fuel reserves, as well as the impact on the environment of fossil fuel uses, the exploration of usable renewable e...

The Itamaraca island close to the state of Pernambuco in Brazil receives thousands of visitors during the period of long summer vacations (3 months), increasing the peak demand by a factor of almost 200%. The purpose of this work is to demonstrate that the offshore wind turbines can meet peak energy demand and at the same time reduce impact on conventional energy generation during other months as well. The method involves a nautical wind map at a height of 10 m, and extrapolating it for the desi...

In this paper, along with the progress of modern wind energy technology, the trends of wind energy technology and potential challenges have been studied thoroughly. It is estimated that within the next 2–3 decades, the Vertical Axis Wind Turbine (VAWT) can dominate the wind-energy technology. The VAWT requires less land space and using the same space; it is capable of producing more wind energy than that of its counterpart. By implying the Fish Schooling Concept effectively and successfully, it ...

An overview of the availability and affordability of energy sources and generation potential in Brazil is given in the present manuscript. Most of the information given here up-to-now was only accessible to Portuguese speakers, such as found in governmental plans for the energy sector. Brazilian public strategy for the following years concentrates on the promotion of more efficient energy utilization in different sectors of the society and also on diversifying its energy matrix. A perspective of...

Wind power has been the fastest growing form of renewable energy for the last few years. According to Intergovernmental Panel on Climate Change (IPCC) report, 80% of the world's energy supply could come from renewable sources by 2050 and wind energy will play a major role in electricity generation in 2050. In the growing market for wind energy and the limited available space onshore, the development of offshore wind farms become more and more important. With a rapid development of technology, th...

Offshore wind energy continues to be a potential candidate for meeting the electricity consumption needs of the Chilean population for decades to come. However, the Chilean energy market is skeptical about exploiting offshore marine energy. At present, there are no offshore marine energy farms. This is probably attributable to the current legal framework, payback period, initial costs of inversions, and future wind speed trends. This work aims to break this paradigm by advancing knowledge regard...

Abstract In this study, based on the Japanese 55-year Reanalysis (JRA-55) dataset, the spatio-temporal variations of wind resources were analyzed in the South China Sea. An approach to determine suitable locations of offshore wind energy extraction was proposed and applied to the south and southeast coasts of China. The approach took into account various criteria, including long-term change and wave condition, with different weights. The results showed that Luzon Strait and Taiwan Strait have hi...

Since energy is one of the basic inputs for development, emerging economies should make an effort to investigate the environmental impacts of their fast economic growth. However, large emerging economies present significant regional heterogeneity that is usually uncounted for. This study uses the Stochastic Impacts by Regression on Population, Affluence and Technology (STIRPAT) model and regional data on the 27 Brazilian states to investigate the growth-CO2 nexus under distinct development stage...

Offshore wind technology in a global context is developing with extraordinary speed, and technical constraints are gradually decreasing. However, in Turkey, offshore applications are yet to be established despite the installation of a significant number of onshore wind power plants over the last ten years.

Abstract The paper presents an assessment of the technical potential of the offshore wind resources of the Southeast and South regions along the Brazilian coastline using atmospheric reanalysis databases. At first, three atmospheric reanalysis databases, CFSv2, ERA5 and MERRA2, are validated using measured data provided by the PNBOIA program. Afterwards, to estimate the technical potential, two approaches are considered for calculating the usable area on the sea surface. The first approach consi...
