“…Essentially, per capita electricity demand was estimated by fitting a multiple regression on historical data from 1980 to 2010, using GDP per capita, and industrial and residential price of electricity as predictors of per capita demand. Thus by the year 2030 the total yearly electricity demand is forecast to be 823 TWh, in line with [4].…”

“…33% decrease in current electricity demand by 2030, due to the extensive use of electric vehicles. Following the work outlined in [4], in which the authors forecast the overall aggregated electricity demand in 2030 as a product of the estimated electricity demand per capita and the predicted population around this time. Essentially, per capita electricity demand was estimated by fitting a multiple regression on historical data from 1980 to 2010, using GDP per capita, and industrial and residential price of electricity as predictors of per capita demand.…”

“…To compensate for the offline nuclear reactors a significant amount of fossil fuel power was brought online, which resulted in increases in the imports of natural gas and heavy fuel oil (up by 36% and 121%, respectively) [3]. This has had a significant economic and environmental impact [4], given the rise in fossil fuel imports and the increase in greenhouse gas emissions.…”

“…A number of studies in the past [4,[9][10][11][12][13] have examined future possible energy generation mixes in Japan, though these typically do not evaluate the reliability and actual feasibility of the proposed energy scenarios. Essentially, most authors simplify the analysis to yearly or monthly averages, ignoring daily and hourly supply/demand fluctuations [14,15].…”

100% renewable energy system in Japan: Smoothening and ancillary services

In the aftermath of the Paris Agreements, many countries around the globe have pledged to reduce the amount of greenhouse gas emissions being released into the atmosphere. To do so, it is important that the amount of renewable energy in the electricity grid increases, though there are worries of the capacity of the grid to cope with intermittent energy sources. To assess the feasibility of a 100% renewable energy system in Japan, the authors conducted an hourly simulation of future electricity production based on wind, solar and tidal data in Japan. The system was shown to be stable, and the authors calculated the required capacity of electrical batteries that would be necessary to balance such a system.

“…Vázquez-Rowe et al[28] studied two cases for Peru and Spain analyzing their changing electricity grids to explore the influence of climate-centric policy-making on long-term electricity mix change. Pereira et al [29] designed four scenarios to evaluate the co-benefits implications of alternative electricity generation scenarios in Japan in a post-Fukushima context, providing a reference for policy-maker among various candidate options including fossil fuels, nuclear energy, and renewable energy. After that, Pereira and his colleagues [30] evaluated the impacts of life cycle assessment greenhouse gas (LCA-GHG) emissions in the power supply portfolio and the effectiveness of a carbon tax scheme.…”

The distributed renewable energy system, integrating various renewable energy resources, is a significant energy supply technology within energy internet. It is an effective way to meet increasingly growing demand for energy conservation and environmental damage reduction in energy generation and energy utilization. In this paper, the life cycle assessment (LCA) method and fuzzy rough sets (FRS) theory are combined to build an environmental evaluation model for a distributed renewable energy system. The ReCiPe2016 method is selected to calculate the environmental effect scores of the distributed energy system, and the FRS is utilized to identify the crucial activities and exchanges during its life cycle from cradle to grave. The generalized evaluation method is applied to a real-world case study, a typical distributed energy system located in Yanqing District, Beijing, China, which is composed of wind power, small-scale hydropower, photovoltaic, centralized solar thermal power plant and a biogas power plant. The results show that the environmental effect of per kWh power derived from the distributed renewable energy system is 2.06 × 10−3 species disappeared per year, 9.88 × 10−3 disability-adjusted life years, and 1.75 × 10−3 USD loss on fossil resources extraction, and further in the uncertainty analysis, it is found that the environmental load can be reduced effectively and efficiently by improving life span and annual utilization hour of power generation technologies and technology upgrade for wind turbine and photovoltaic plants. The results show that the proposed evaluation method could fast evaluate the environmental effects of a distributed energy system while the uncertainty analysis with FRS successfully and effectively identifies the key element and link among its life span.
