The Impact

This research considered changes in monthly electricity generation and demand in Japan during the COVID-19 pandemic. Observed network electricity demand and generation type for the January–June 2020 period were compared to forecast values (using a triple exponential smoothing method) based on trends established from 2016 to 2019. Regional level electricity demand data showed little variation from expected trends for domestic energy users, but lower than expected business and industrial network demand, particularly in the 50–2000 kW cohort. Electricity demand was most likely to deviate from existing trends in May 2020, which is in-line with the voluntary lockdown activities. These results are consistent with observed patterns from other international studies into the impact of COVID-19 on electricity demand. Generation was found to be reduced in May and June of 2020, without significant impacts to the generation makeup, largely due to Japan’s positioning within a broader energy transition context. These findings validate previous studies and add to the broader discussions on drivers and the rationale for electricity demand behaviors between user scales. Previous studies examined the electricity demand reductions of full and partial lockdowns. This analysis adds to this discourse by documenting the impacts of a voluntary lockdown.

This study evaluates potential aggregate effects of net-zero energy building (NZEB) implementations on the electrical grid in simulation-based analysis. Many studies have been conducted on how effective NZEB designs can be achieved, however the potential impact of NZEBs have not been explored sufficiently. As significant penetration of NZEBs occurs, the aggregated electricity demand profile of the buildings on the electrical grid would experience dramatic changes. To estimate the impact of NZEBs on the electrical grid, a simulation-based study of an office building with a grid-tied PV power generation system is conducted. This study assumes that net-metering is available for NZEBs such that the excess on-site PV generation can be fed to the electrical grid. The impact of electrical energy storage (EES) within NZEBs on the electrical grid is also considered in this study. Finally, construction weighting factors of the office building type in U.S. climate zones are used to estimate the number of national office buildings. In order to consider the adoption of NZEBs in the future, this study examines scenarios with 20%, 50%, and 100% of the U.S. office building stock are composed of NZEBs. Results show that annual electricity consumption of simulated office buildings in U.S. climate locations includes the range of around 85 kWh/m2-year to 118 kWh/m2-year. Each simulated office building employs around 242 kWp to 387 kWp of maximum power outputs in the installation of on-site PV power systems to enable NZEB balances. On a national scale, the daily on-site PV power generation within NZEBs can cover around 50% to 110% of total daily electricity used in office buildings depending on weather conditions. The peak difference of U.S. electricity demand typically occurs when solar radiation is at its highest. The peak differences from the actual U.S. electricity demand on the representative summer day show 9.8%, 4.9%, and 2.0% at 12 p.m. for 100%, 50%, and 20% of the U.S. NZEB stocks, respectively. Using EES within NZEBs, the peak differences are reduced and shifted from noon to the beginning of the day, including 7.7%, 3.9%, and 1.5% for each percentage U.S. NZEB stock. NZEBs tend to create the significant curtailment of the U.S. electricity demand profile, typically during the middle of the winter day. The percentage differences at a peak point (12 p.m.) are 8.3%, 4.2%, and 1.7% for 100%, 50%, and 20% of the U.S. NZEB stocks, respectively. However, using EES on the representative winter day can flatten curtailed electricity demand curves by shifting the peak difference point to the beginning and the late afternoon of the day. The shifted peak differences show 7.4%, 3.7%, and 1.5% at 9 a.m. for three U.S. NZEB stock scenarios, respectively.

In the early 2020s the worlds transition from carbon-intensive to climate-neutral energy use has already become a discernible and a difficult-to-reverse process. With Joe Bidens election as US president, the United States have returned to the Paris Climate Agreement and have become a key driver of this process (along with the EU and China). As a result, the international community has reached a consensus on the ongoing energy transition. This process will require considerable effort and may take several decades. Nevertheless, the impact of energy transition on traditional approaches to energy security, which emerged largely as a result of the global oil crises of the 1970s and 1980s and are centered around the supply of fossil fuels, is already a relevant research topic. This problem is examined relying on the relevant terminological, theoretical and factual material. The article concludes that energy transition will ultimately undermine the carbon paradigm that has underpinned energy security policies since the 1970s. Rapid development of renewable and other low-carbon energy sources will certainly remove key energy security risks of energy importers and, possibly, allow them to achieve energy independence. However, a post-carbon era may also generate new risks. For countries that rely heavily on oil, gas and coal exports, energy transition will result in the loss of markets and revenues. It may present an energy security threat for them as well as it will require a costly and technologically complex process of the energy sector decarbonization. Some exporters, especially those with high fuel rents and insufficient financial reserves, may face serious economic and social upheavals as a result of energy transition. The EU and the US energy transition policies reflect provisions of all three fundamental international relations theoretical paradigms, including realism. This means that the EU and the US policy, aimed at promoting climate agenda, may be expected to be rather tough and aggressive. China as the third key player in energy transition is still following a liberal course; however, it may change in the future.

Abstract This study focuses on the role of institutional factors as well as financial development in renewable energy transition in Middle East and North Africa (MENA) region over the period 1990-2018 using the ARDL PMG method. The investigation of long-run and short-run analysis confirms that institutional and political factors play a key role in promoting the transition to renewable energy, and shows that improving these factors can lead to decarbonization of the energy sector in the long run. Another important finding is that global financial development does not have a significant effect on the transition process in the long run, implying that the whole financial system needs a fundamental structural change to accelerate the substitution between polluting and clean energies. However, in the short term, the impact appears to be negative and significant, highlighting the inadequacy of financial institutions and financial markets in promoting the region’s sustainable path. Moreover, income drives the transition to renewable energy in both short and long term. The causality results show that both financial development and institutional quality lead to renewable energy transition, while there is a bidirectional link between income and renewable energy.This study can provide a very useful recommendation to promote a clean transition in the MENA region.

The present paper presents an analysis on the role of Natural Gas (NG) in Portugal facing the new requirements. The analyses is based on the economic, societal and environmental aspects, being the major reasons to align the Government strategy, define policies and reproduce the EU directives. The analyses do not reflect on the pandemic and financial crisis because the author considers that these factors are outside of the energy system and have not been steady along the period in study, thereby it can mislead the conclusions. This study relies mostly on non-empirical research, in which the research adopted both inductive and deductive reasoning to theorize logical assumptions about the Portuguese energy market. Building on reflection and personal observation on the field, the researchers carried out this article by gathering relevant data (i.e., statistics) through critical studies, systematic review of literature and meta-analysis on the theme. Therefore, the methodology used is based mainly on qualitative exploration of secondary sources and data, out of which one will pull out insights. The novelty of the study is to take in consider-ation all the above factors and produce results that are more adequate to reality, as all of them are interconnected and by changing one of them it will be changes in the remain. The open literature mainly focusses on the economic, the energetic, the social or the environmental aspects and neglects the others. One can conclude that there is economic advantage on efficiently distributing and consuming NG. Also, the impact of NG on a society welfare is positive. Last, the NG brings flexibility to the grid, which is more and more important in the perspective and ambition to increase the share of intermittent renewable energies.

The Relationship

Russia is the world’s largest gas exporter and Germany is its most important market. Moreover, natural gas is a centerpiece of the Russian economy and the backbone of its energy supply to the Russian population. In terms of its external gas relations, Germany has always kept a special and strategic position, both in terms of volumes, but also in substance. This contribution explores the impact of the energy transition on the bilateral gas relationship. It argues that the bilateral gas relationship has been subjected to various paradigm shifts in the past, but, until recently, the relationship has been seen as in line with the strategic energy triangle of climate change/sustainability, supply security and economic competitiveness. This perception has come into question over two issues: climate change and supply security. Moreover, Germany’s authority over the conduct and the legal framework of bilateral gas relations has been increasingly contested, by Brussels, but also horizontally by other EU member states. At this stage, it is very uncertain whether both sides will manage to maintain and redefine their close energy partnership to address climate change. Decarbonizing the gas value chain would be a centerpiece. This would require a political shift away from securitization to decarbonization, not only in Germany, but even more so in the EU, and in particular, in Russia.

Over Time

While access to reliable electricity can significantly constrain industrial production, little is known as to how unreliability impacts firm level productivity. This is a particularly salient issue for firms in developing countries, where electricity provision is still unreliable and self-generation is costly. This paper analyzes the impact of electricity provision on productivity, instrumenting for electricity demand with district level solar irradiance. Results indicate that firms exhibit decreasing productivity in the initial stages of electricity adoption that decreases over time. Furthermore, I find that unreliability negatively impacts productivity initially and over time, and this effect is larger for smaller firms.

The Impact

In an era of energy transition involving an increase in renewable energy and a reduction in coal-fired power generation and nuclear power generation, the role of combined heat and power (CHP) as a bridging energy is highly emphasized. This article attempts to look empirically into the impact of increasing the share of renewable energy in total electricity generation on CHP share in total electricity generation in a cross-country context. Data from 35 countries during the period 2009–2015 were used, and the least absolute deviations estimator was applied to obtain a more robust parameter estimate. The results showed that a 1%p increase in the share of renewable energy significantly increased the CHP share by 0.87%p. Therefore, the hypothesis that CHP serves as bridge energy in the process of energy transition was established.

The Impact

In this article, we empirically investigate the impact of the population age structure on electricity demand. Our study is motivated by suggestions from existing literature that demographic factors can play an important role in energy demand. Using Korean regional level panel data for 2000 to 2016, we estimate the long-run elasticities through employing cointegration regression and the short-run marginal effects by developing a panel error correction model. It is worth investigating the Korean case, since Korea is aging faster than any other advanced economy, and at the same time is one of the heaviest energy users in the world. To our knowledge, this is the first study analyzing how the population age structure affects residential electricity demand, based on regional data in Korea. Our analysis presents the following results. First, an increase in the youth population raises the residential electricity demand in the short- and long-run. Second, an increase in the population of people aged 65 and over also increases this electricity demand in the short- and long-run. Third, among the group of people aged 65 and over, we further investigate the impact of an older population group, aged 80 and over, but separately, on their residential electricity demand. However, in general there is no strong relationship in the short- and long-run.
