The Positive Energy District (PED) concept has been pointed out as key for cities' energy system transformation toward carbon neutrality. The PED may be defined as an energy-efficient and flexible urban area with net-zero energy import and greenhouse gas emissions, aiming toward annual local surplus of renewable energy. Most of the studies and practical experiences about PEDs are based on newly built districts, where the planning and integration of innovative solutions are less complex and more cost-effective. However, to achieve Europe Union's 2050 carbon-neutral ambition, we argue that the transformation of the settled districts is essential, including historic districts, which present common challenges across European cities, such as degraded dwellings, low-income families, and gentrification processes due to massive tourism flows. This paper aims to discuss how the PED model can be an opportunity for historic districts to reduce their emissions and mitigate energy poverty. The historic district of Alfama, in the city of Lisbon (Portugal), is used as a case study to show the potential of energy renovation measures and solar PV production in households, cornerstones of a PED. The annual energy needs potential reduction due to building retrofit is 84 and 19% for space heating and cooling, respectively, while the integration of building-integrated PV technologies in rooftops and windows potentially generates up to 60 GWh/year. At the district scale, these two components of the PED concept could require an investment of 60M€ to 81M€ depending on the PV technologies in the rooftops, a sensitive aspect in historical districts. Unlike other mechanisms to tackle energy poverty, like the social tariffs, the adoption of structural measures like building energy efficiency retrofit and renewable energy integration will contribute to solve the energy poverty problem, which is significant in Alfama, in both the winter and summer. The highlighted investments require an innovative financial scheme to support not only buildings' owners but also tenants, as these are among the most vulnerable to energy poverty. However, the social benefits of that investment, on the health system, air quality, climate resilience, labor productivity, and social integration, would be invaluable.

In the past years, Dutch citizens have experimented with various kinds of innovations to organize the collective production of renewable energy, including shared wind power and solar PV installations. Most of these attempts failed mainly due to legal issues and tax rules. Yet, one model for solar PV on collective roofs was implemented more widely, namely the postcode rose (PCR, postcoderoos): a form of cooperative solar PV production within a set of adjacent postcode areas. Set within a broader transition perspective, this article studies the emergence and evolution of the PCR as an example of a successful social innovation in the energy transition, through an innovation biography and mapping of the evolution of the social and institutional network around the innovation. The various attempts for collective solar PV, with different degrees of success and uptake into the regime, present a key aspect of niche development, namely associational work (circulation and mobilization) focused on regime change. In conclusion, the innovation path of the PCR emphasizes the importance of the political and associational in the energy transition and in transition thinking.

Energy Justice

The threats climate change poses require rapid and wide decarbonization efforts in the energy sector. Historically, large-scale energy operations, often instrumental for a scaled and effective approach to meet decarbonization goals, undergird energy-related injustices. Energy poverty is a multi-dimensional form of injustice, with relevance to low-carbon energy transitions. Defined as the condition of being unable to access an adequate level of household energy services, energy poverty persists despite the emergence of affordable renewable energy technologies, such as solar photovoltaics (PV). Historical injustices and the modularity of solar PV combine to offer new possibilities in ownership, production and distribution of cost-competitive, clean and collectively scalable energy. Consequently, emerging policy priorities for positive energy districts call into question the traditional large-scale modality of energy operations. We report from a case study of solar power in Lisbon, a frontrunner in urban energy transitions while also home to high energy poverty incidence. The study focuses on scalar aspects of justice in energy transitions to investigate whether and how solar PV can alleviate urban energy poverty. It features 2 months of fieldwork centered on community and expert perspectives, including semi-structured interviews and field observations. We mobilize a spatial energy justice framework to identify justice aspects of multi-scalar solar PV uptake. By showing how energy justice is shaped in diverse ways at different scales, we demonstrate ways in which scale matters for just urban energy transitions. We argue that small- and medium-scaled approaches to electricity distribution, an integral component of positive energy districts, can address specific justice concerns. However, even as such approaches gain attention and legitimacy, they risk structurally excluding socio-economically vulnerable users, and proceed slowly relative to large-scale solar rollout.

Abstract Energy transitions and decarbonization require rapid changes to a nation’s generation mix. There are a host of possible decarbonization pathways, yet there is vast uncertainty about how different decarbonization pathways will advance or derail the nation’s energy equality goals. We present a framework for investigating how decarbonization pathways, driven by a least cost paradigm, will lead to air pollution inequality across different vulnerabilities (e.g., low-income, energy poverty). If an equitable energy transition is the goal (i.e., one that reaches total equality), using least cost optimization capacity expansion models without strict renewable energy technology mandates will not accomplish this. Thus, it is imperative that decisions regarding national regarding national decarbonization pathways have strict mandates for equality outcomes or be driven by an equality focused paradigm.

The work of the Welfare Warriors Research Collaborative (WWRC), a participatory action research (PAR) project that looks at how low income lesbian, gay, bisexual, transgender, and gender nonconforming (LG-BTGNC) people survive and resist violence and discrimination in New York City, raises the question of what it means to make conscientization, or critical consciousness, a core feature of PAR. Guishard's (2009) reconceptualization of conscientization as “moments of consciousness” provides a new way of looking at what seemed to be missing from WWRC's process and analysis. According to Guishard, rather than a singular awakening, critical consciousness emerges continually through interactions with others and the social context. Analysis of the WWRC's process demonstrates that PAR researchers doing “PAR deep” (Fine, 2008)—research in which community members share in all aspects of design, method, analysis and product development—should have an agenda for developing critical consciousness, just as they would have agendas for participation, for action, and for research.

East African Community

The article analyses the role of renewable energy in the process of the development of the energy market of the East African Community (EAC) . The author underlines the necessity of finding solutions for such challenges as rising wood and charcoal prices, deforestation, lack of affordable and reliable electricity for a large number of consumers. The study reveals that nowadays the percentage of people with access to modern sources of energy is very low, varying from 7 % in Burundi to 36% in Kenya, although the EAC countries made significant progress in 2000s. Most people in rural areas rely on traditional biomass for cooking and heating, which leads to ecological and health problems. The author concludes that renewable energy development is considered by the Community as one of the prospective ways for providing energy to remote regions in view of abundant solar, wind and geothermal resources. Their strategy aims at the construction of micro and mini hydro stations, stand-alone solar PV systems and off-grids for rural population usage. The study shows that the investment in off-grid renewables has been steadily rising in recent times . Analyzing grid-connected power generation electricity, the author elicits that it is also based on renewable electricity, which accounts for 65% of the total amount. Kenya, with the highest installed capacity in this sector, is investing mainly in geothermal, solar and wind sources of energy, while the others are focusing on hydropower and solar. For the purpose of attracting private investment, the EAC partner states adopted different regulations, including Feed-in Tariff, zero-VAT and GET FIT Programme. The author assumes that renewable energy financing is one of the main challenges despite the support of different international financial institutions, such as the World Bank, UNIDO, AfDB and others. Nowadays energy efficiency measures are becoming important instruments for the EAC countries resulted in power savings. The other important trend is increasing cooperation among them due to their grid-connected power systems in the East African Power Pool. In this context, in November 2017, the EAC Partner States adopted Energy Security Policy Framework, in order to ensure the sustainable development of their energy sector.

BACKGROUND The Covid-19 pandemic had turned the world upside down, but not much is known about how people’s empathy might be affected by the pandemic. OBJECTIVE This study examined 1) how empathy towards others might be influenced by the social support people obtained by using social media; and 2) how the individual demographics (e.g., age, income) may affect empathy. METHODS A national survey (N = 943) was conducted in China in February 2020, in which the participants read three real scenarios about low-income urban workers (Scenario I), small business owners in cities (Scenario II), and farmers in rural areas (Scenario III) who underwent hardship due to COVID-19. After exposure to others’ difficulties in the scenarios, the participants’ empathy and anxiety levels were measured. We also measured the social support they had by using social media. RESULTS Results show that social support not only positively impacted empathy, β = .30, P < .001 for Scenario I, β = .30, P < .001 for Scenario II, and β = .29, P < .001 for Scenario III, but also interacted with anxiety in influencing the degree to which participants could maintain empathy towards others, β = .08, P = .010 for Scenario I, and β = .07, P = .033 for scenario II. Age negatively predicted empathy for Scenario I, β = -.08, P = .018 and Scenario III, β = -.08, P = .009, but not for Scenario II, β = -.03, P = .40. Income levels – low, medium, high – positively predicted empathy for Scenario III, F (2, 940) = 8.10, P < .001, but not for Scenario I, F (2, 940) = 2.14, P = .12, or Scenario II, F (2, 940) = 2.93, P = .06. Participants living in big cities expressed greater empathy towards others for Scenario III, F (2, 940) = 4.03, P =.018, but not for Scenario I, F (2, 940) = .81, P = .45, or Scenario II, F (2, 940) = 1.46, P =.23. CONCLUSIONS This study contributes to the literature by discovering the critical role empathy plays in people’s affective response to others during the pandemic. Anxiety did not decrease empathy. However, those gaining more social support on social media showed more empathy for others. Those who resided in cities with higher income levels were more empathetic during the COVID-19 outbreak. This study reveals that the social support people obtained helped maintain empathy to others, making them resilient in challenging times.

Renewable generation sources still have not achieved economic validity in many countries including Korea, and require subsidies to support the transition to a low-carbon economy. An initial Feed-In Tariff (FIT) was adopted to support the deployment of renewable energy in Korea until 2011 and then was switched to the Renewable Portfolio Standard (RPS) to implement more market-oriented mechanisms. However, high volatilities in electricity prices and subsidies under the RPS scheme have weakened investment incentives. In this study we estimate how the multiple price volatilities under the RPS scheme affect the optimal investment decisions of energy storage projects, whose importance is increasing rapidly because they can mitigate the variability and uncertainty of solar and wind generation in the power system. We applied mathematical analysis based on real-option methods to estimate the optimal trigger price for investment in energy-storage projects with and without multiple price volatilities. We found that the optimal trigger price of subsidy called the Renewable Energy Certificate (REC) under multiple price volatilities is 10.5% higher than that under no price volatilities. If the volatility of the REC price gets doubled, the project requires a 26.6% higher optimal investment price to justify the investment against the increased risk. In the end, we propose an auction scheme that has the advantage of both RPS and FIT in order to minimize the financial burden of the subsidy program by eliminating subsidy volatility and find the minimum willingness-to-accept price for investors.
