2023 SEP 15 (NewsRx) -- By a News Reporter-Staff News Editor at Ecology Daily News -- Investigators discuss new findings in Energy - Wind Energy. According to news reporting out of Harbin, People’s Republic of China, by NewsRx editors, research stated, “Intermittent renewable energy sources have been transformed from supplementary energy to dominant incre-mental alternative energy sources in the context of carbon neutrality target worldwide. For coastal countries, it is urgent to integrate abundant offshore energy into regional onshore renewable power sources economically and reliably considering the scarcity of land resources and negative environmental impacts.”
Financial supporters for this research include Natural Science Foundation of Zhejiang Province, Donghai Academy of Ningbo University, Second Tibetan Plateau Scientific Expedition and Research, project of philosophy and social science planning in Zhejiang Province.
Our news journalists obtained a quote from the research from the Heilongjiang University of Science & Technology, “However, limited knowledge on the complex spatiotemporally synergy relationships between energy potential (onshore and offshore) is a barrier in making reasonable policies to promote collaborative development of onshore and offshore energies. This study presents a spatiotemporally explicit modelling framework for assessing the synergy potential characteristics of onshore and offshore renewable energy sources. The framework firstly estimates the technical potential of solar PV and wind energy across the country by using 40 years of hourly meteorological reanalysis data (1980-2020), and then investigates the long-term changes trend, stability, and complementarity of solar-wind energy potential spatiotemporally at both onshore and offshore sub-regions. We find that a considerable amount of solar PV and wind energy sources could be harnessed in China, and onshore potential across the country (178 PWh/yr) is approximate 20 times higher than offshore energy potential (8.9 PWh/yr). Overall, onshore solar-wind energy potentials exhibit statistically insignificant but slightly increasing trend over the past 40 years, while offshore wind potentials observe an opposite change trend for solar PV and wind energy production. Complementarity assessment showed the northeast and offshore parts of China present high complementarity effects for hourly and daily power production of solar-wind systems. Furthermore, inter-regional combination between offshore and onshore northwest regions also exhibits promising synergy effect for renewable energy power output. The results on resources dynamic and complementarity highlight the advantage of interregional resources cooperative configuration and electric power grid interconnections.”
According to the news editors, the research concluded: “The analysis performed in this paper could provide a global picture for the integration planning and collaborative development strategies formulation of on-/offshore renewable energy across the country.”
