A residential labeled dataset for smart meter data analytics
Authors: Pereira, L.; Costa, D.; Ribeiro, M.
Journal: Scientific Data (2022)

AbstractSmart meter data is a cornerstone for the realization of next-generation electrical power grids by enabling the creation of novel energy data-based services like providing recommendations on how to save energy or predictive maintenance of electric appliances. Most of these services are developed on top of advanced machine-learning algorithms, which rely heavily on datasets for training, testing, and validation purposes. A limitation of most existing datasets, however, is the scarcity of

AbstractWe present a new high resolution wind resource and wind power dataset named NORA3-WP. The dataset covers the North Sea, the Baltic Sea and parts of the Norwegian and Barents Seas. The 3-km Norwegian reanalysis (NORA3) forms the basis for the new dataset. NORA3-WP is an open access dataset intended for use in research, governmental management and for stakeholders to attain relevant wind resource and wind power information in the planning phase of a new wind farm project. The variables are
Energy audit and carbon footprint in trawl fisheries
Authors: Sala, A.; Damalas, D.; Labanchi, L.; Martinsohn, J.; Moro, F.
Journal: Scientific Data (2022)

AbstractThe combustion of fossil fuels is considered a major cause of climate change, which is why the reduction of emissions has become a key goal of the Paris climate agreement. Coherent monitoring of the energy profile of fishing vessels through an energy audit can effectively identify sources of inefficiency, allowing for the deployment of well-informed and cost-efficient remedial interventions. We applied energy audits to a test fleet of ten vessels, representing three typical Mediterranean
Historical red-lining is associated with fossil fuel power plant siting and present-day inequalities in air pollutant emissions
Authors: Cushing, L.; Li, S.; Steiger, B.; Casey, J.
Journal: Nature Energy (2022)

AbstractStationary sources of air pollution are disproportionately located in communities of colour, but the causes for this disparity are unclear. Here we assess whether racialized appraisals of investment risk (‘red-lining’) undertaken by the US federal Home Owners’ Loan Corporation in the 1930s influenced the subsequent siting of fossil fuel power plants. Across 8,871 neighbourhoods in 196 US urban areas, we observed a stepwise correlation between risk grade, number of power plants and cumula
High-performing organic electronics using terpene green solvents from renewable feedstocks
Authors: Corzo, D.; Rosas-Villalva, D.; C, A.; Tostado-Blázquez, G.; Alexandre, E.
Journal: Nature Energy (2022)

AbstractAccelerating the shift towards renewable materials and sustainable processes for printed organic electronic devices is crucial for a green circular economy. Currently, the fabrication of organic devices with competitive performances is linked to toxic petrochemical-based solvents with considerable carbon emissions. Here we show that terpene solvents obtained from renewable feedstocks can replace non-renewable environmentally hazardous solvent counterparts in the production of highly effi
Planning sustainable electricity solutions for refugee settlements in sub-Saharan Africa
Authors: Baldi, D.; Moner-Girona, M.; Fumagalli, E.; Fahl, F.
Journal: Nature Energy (2022)

AbstractAn inadequate understanding of the energy needs of forcibly displaced populations is one of the main obstacles in providing sustainable and reliable energy to refugees and their host communities. Here, we provide a first-order assessment of the main factors determining the decision to deploy fully renewable mini-grids in almost 300 refugee settlements in sub-Saharan Africa. Using an energy assessment survey and publicly available traditional and earth observation data, we estimate a tota
Charging infrastructure access and operation to reduce the grid impacts of deep electric vehicle adoption
Authors: Powell, S.; Cezar, G.; Min, L.; Azevedo, I.; Rajagopal, R.
Journal: Nature Energy (2022)

AbstractElectric vehicles will contribute to emissions reductions in the United States, but their charging may challenge electricity grid operations. We present a data-driven, realistic model of charging demand that captures the diverse charging behaviours of future adopters in the US Western Interconnection. We study charging control and infrastructure build-out as critical factors shaping charging load and evaluate grid impact under rapid electric vehicle adoption with a detailed economic disp
Rapid battery cost declines accelerate the prospects of all-electric interregional container shipping
Authors: Kersey, J.; Popovich, N.; Phadke, A.
Journal: Nature Energy (2022)

AbstractInternational maritime shipping—powered by heavy fuel oil—is a major contributor to global CO2, SO2, and NOx emissions. The direct electrification of maritime vessels has been underexplored as a low-emission option despite its considerable efficiency advantage over electrofuels. Past studies on ship electrification have relied on outdated assumptions on battery cost, energy density values and available on-board space. We show that at battery prices of US$100 kWh−1 the electrification of
Anticipating and defusing the role of conspiracy beliefs in shaping opposition to wind farms
Authors: Winter, K.; Hornsey, M.; Pummerer, L.; Sassenberg, K.
Journal: Nature Energy (2022)

AbstractReaching net-zero targets requires massive increases in wind energy production, but efforts to build wind farms can meet stern local opposition. Here, inspired by related work on vaccinations, we examine whether opposition to wind farms is associated with a world view that conspiracies are common (‘conspiracy mentality’). In eight pre-registered studies (collectiveN = 4,170), we found moderate-to-large relationships between various indices of conspiracy beliefs and wind farm opposition.
Understanding India’s low-carbon energy technology startup landscape
Authors: Krishna, H.; Kashyap, Y.; Dutt, D.; Sagar, A.; Malhotra, A.
Journal: Nature Energy (2022)

AbstractLow-carbon energy technology (LCET) startups could play a key role in accelerating India’s decarbonization. Yet, our understanding of the LCET startup landscape and what shapes it remains low. Here we provide an analysis of the Indian LCET startup landscape to fill this gap. Our descriptive analysis of quantitative data on investment and patenting activities of LCET startups from 2010 to 2020 and qualitative data from 25 semi-structured interviews shows a substantial increase in investme
Energy demand reduction options for meeting national zero-emission targets in the United Kingdom
Authors: Barrett, J.; Pye, S.; Betts-Davies, S.; Broad, O.; Price, J.
Journal: Nature Energy (2022)

AbstractIn recent years, global studies have attempted to understand the contribution that energy demand reduction could make to climate mitigation efforts. Here we develop a bottom-up, whole-system framework that comprehensively estimates the potential for energy demand reduction at a country level. Replicable for other countries, our framework is applied to the case of the United Kingdom where we find that reductions in energy demand of 52% by 2050 compared with 2020 levels are possible withou
Re-thinking procurement incentives for electric vehicles to achieve net-zero emissions
Authors: Nunes, A.; Woodley, L.; Rossetti, P.
Journal: Nature Sustainability (2022)

AbstractProcurement incentives are a widely leveraged policy lever to stimulate electric vehicle (EV) sales. However, their effectiveness in reducing transportation emissions depends on the behavioural characteristics of EV adopters. When an EV is used, under what conditions and by whom dictates whether or not these vehicles can deliver emissions reductions. Here, we document that replacing gasoline powered vehicles with EVs may—depending on behavioural characteristics—increase, not decrease, em
Earthquake breakdown energy scaling despite constant fracture energy
Authors: Ke, C.; McLaskey, G.; Kammer, D.
Journal: Nature Communications (2022)

AbstractIn the quest to determine fault weakening processes that govern earthquake mechanics, it is common to infer the earthquake breakdown energy from seismological measurements. Breakdown energy is observed to scale with slip, which is often attributed to enhanced fault weakening with continued slip or at high slip rates, possibly caused by flash heating and thermal pressurization. However, seismologically inferred breakdown energy varies by more than six orders of magnitude and is frequently
Energy requirements and carbon emissions for a low-carbon energy transition
Authors: Slameršak, A.; Kallis, G.; O’Neill, D.
Journal: Nature Communications (2022)

AbstractAchieving the Paris Agreement will require massive deployment of low-carbon energy. However, constructing, operating, and maintaining a low-carbon energy system will itself require energy, with much of it derived from fossil fuels. This raises the concern that the transition may consume much of the energy available to society, and be a source of considerable emissions. Here we calculate the energy requirements and emissions associated with the global energy system in fourteen mitigation
Unveiling hidden energy poverty using the energy equity gap

Abstract
                  
                    Income-based energy poverty metrics ignore people’s behavior patterns, particularly reducing energy consumption to limit financial stress. We investigate energy-limiting behavior in low-income households using a residential electricity consumption dataset. We first determine the outdoor temperature at which households start using cooling systems, the inflection temperature. Our relative energy poverty metric, the

Temperature-dependent dual-mode thermal management device with net zero energy for year-round energy saving
Authors: Zhang, Q.; Lv, Y.; Wang, Y.; Yu, S.; Li, C.
Journal: Nature Communications (2022)

AbstractReducing needs for heating and cooling from fossil energy is one of the biggest challenges, which demand accounts for almost half of global energy consumption, consequently resulting in complicated climatic and environmental issues. Herein, we demonstrate a high-performance, intelligently auto-switched and zero-energy dual-mode radiative thermal management device. By perceiving temperature to spontaneously modulate electromagnetic characteristics itself, the device achieves ~859.8 W m−2
Giant bulk photovoltaic effect driven by the wall-to-wall charge shift in WS2 nanotubes
Authors: Kim, B.; Park, N.; Kim, J.
Journal: Nature Communications (2022)

AbstractThe intrinsic light–matter characteristics of transition-metal dichalcogenides have not only been of great scientific interest but have also provided novel opportunities for the development of advanced optoelectronic devices. Among the family of transition-metal dichalcogenide structures, the one-dimensional nanotube is particularly attractive because it produces a spontaneous photocurrent that is prohibited in its higher-dimensional counterparts. Here, we show that WS2 nanotubes exhibit
Cosmogenic radionuclides reveal an extreme solar particle storm near a solar minimum 9125 years BP
Authors: Paleari, C.; Mekhaldi, F.; Adolphi, F.; Christl, M.; Vockenhuber, C.
Journal: Nature Communications (2022)

AbstractDuring solar storms, the Sun expels large amounts of energetic particles (SEP) that can react with the Earth’s atmospheric constituents and produce cosmogenic radionuclides such as14C,10Be and36Cl. Here we present10Be and36Cl data measured in ice cores from Greenland and Antarctica. The data consistently show one of the largest10Be and36Cl production peaks detected so far, most likely produced by an extreme SEP event that hit Earth 9125 years BP (before present, i.e., before 1950 CE), i.
Decapod-inspired pigment modulation for active building facades
Authors: Kay, R.; Katrycz, C.; Nitièma, K.; Jakubiec, J.; Hatton, B.
Journal: Nature Communications (2022)

AbstractTypical buildings are static structures, unable to adjust to dynamic temperature and daylight fluctuations. Adaptive facades that are responsive to these unsteady solar conditions can substantially reduce operational energy inefficiencies, indoor heating, cooling, and lighting costs, as well as greenhouse-gas emissions. Inspired by marine organisms that disperse pigments within their skin, we propose an adaptive building interface that uses reversible fluid injections to tune optical tra
Resilience of urban public electric vehicle charging infrastructure to flooding
Authors: Raman, G.; Raman, G.; Peng, J.
Journal: Nature Communications (2022)

AbstractAn adequate charging infrastructure is key to enabling high personal electric vehicle (EV) adoption rates. However, urban flooding—whose frequency and intensity are increasing due to climate change—may be an impediment. Here, we study how geographically-correlated outages due to floods impact public EV charging networks in Greater London. While we find no appreciable impact on the ability of battery EVs to serve typical urban driving behaviors, we observe disproportionate stresses on cha

Simulated co-optimization of renewable energy and desalination systems in Neom, Saudi Arabia
Authors: Riera, J.; Lima, R.; Hoteit, I.; Knio, O.
Journal: Nature Communications (2022)

AbstractThe interdependence between the water and power sectors is a growing concern as the need for desalination increases globally. Therefore, co-optimizing interdependent systems is necessary to understand the impact of one sector on another. We propose a framework to identify the optimal investment mix for a co-optimized water-power system and apply it to Neom, Saudi Arabia. Our results show that investment strategies that consider the co-optimization of both systems result in total cost sav
Synchronization in electric power networks with inherent heterogeneity up to 100% inverter-based renewable generation
Authors: Sajadi, A.; Kenyon, R.; Hodge, B.
Journal: Nature Communications (2022)

AbstractThe synchronized operation of power generators is the foundation of electric power network stability and a key to the prevention of undesired power outages and blackouts. Here, we derive the conditions that guarantee synchronization in power networks with inherent generator heterogeneity when subjected to small perturbations, and perform a parametric sensitivity analysis to understand synchronization with varied types of generators. As inverter-based resources, which are the primary inte
Pathway to a land-neutral expansion of Brazilian renewable fuel production
Authors: Ramirez Camargo, L.; Castro, G.; Gruber, K.; Jewell, J.; Klingler, M.
Journal: Nature Communications (2022)

AbstractBiofuels are currently the only available bulk renewable fuel. They have, however, limited expansion potential due to high land requirements and associated risks for biodiversity, food security, and land conflicts. We therefore propose to increase output from ethanol refineries in a land-neutral methanol pathway: surplus CO2-streams from fermentation are combined with H2 from renewably powered electrolysis to synthesize methanol. We illustrate this pathway with the Brazilian sugarcane et
Data-driven load profiles and the dynamics of residential electricity consumption
Authors: Anvari, M.; Proedrou, E.; Schäfer, B.; Beck, C.; Kantz, H.
Journal: Nature Communications (2022)

AbstractThe dynamics of power consumption constitutes an essential building block for planning and operating sustainable energy systems. Whereas variations in the dynamics of renewable energy generation are reasonably well studied, a deeper understanding of the variations in consumption dynamics is still missing. Here, we analyse highly resolved residential electricity consumption data of Austrian, German and UK households and propose a generally applicable data-driven load model. Specifically,
Uncertainty modulates visual maps during noninstrumental information demand
Authors: Li, Y.; Daddaoua, N.; Horan, M.; Foley, N.; Gottlieb, J.
Journal: Nature Communications (2022)

AbstractAnimals are intrinsically motivated to obtain information independently of instrumental incentives. This motivation depends on two factors: a desire to resolve uncertainty by gathering accurate information and a desire to obtain positively-valenced observations, which predict favorable rather than unfavorable outcomes. To understand the neural mechanisms, we recorded parietal cortical activity implicated in prioritizing stimuli for spatial attention and gaze, in a task in which monkeys w
Electrifying passenger road transport in India requires near-term electricity grid decarbonisation
Authors: Abdul-Manan, A.; Gordillo Zavaleta, V.; Agarwal, A.; Kalghatgi, G.; Amer, A.
Journal: Nature Communications (2022)

AbstractBattery-electric vehicles (BEV) have emerged as a favoured technology solution to mitigate transport greenhouse gas (GHG) emissions in many non-Annex 1 countries, including India. GHG mitigation potentials of electric 4-wheelers in India depend critically on when and where they are charged: 40% reduction in the north-eastern states and more than 15% increase in the eastern/western regions today, with higher overall GHGs emitted when charged overnight and in the summer.

Disruption of the grid cell network in a mouse model of early Alzheimer’s disease
Authors: Ying, J.; Keinath, A.; Lavoie, R.; Vigneault, E.; El Mestikawy, S.
Journal: Nature Communications (2022)

Abstract
                  Early-onset familial Alzheimer’s disease (AD) is marked by an aggressive buildup of amyloid beta (Aβ) proteins, yet the neural circuit operations impacted during the initial stages of Aβ pathogenesis remain elusive. Here, we report a coding impairment of the medial entorhinal cortex (MEC) grid cell network in the J20 transgenic mouse model of familial AD that over-expresses Aβ throughout the hippocampus and entorhinal cortex. Grid cells showed reduced spatial periodici
Comparing the levelized cost of electric vehicle charging options in Europe
Authors: Lanz, L.; Noll, B.; Schmidt, T.; Steffen, B.
Journal: Nature Communications (2022)

AbstractWith rapidly decreasing purchase prices of electric vehicles, charging costs are becoming ever more important for the diffusion of electric vehicles as required to decarbonize transport. However, the costs of charging electric vehicles in Europe are largely unknown. Here we develop a systematic classification of charging options, gather extensive market data on equipment cost, and employ a levelized cost approach to model charging costs in 30 European countries (European Union 27, Great
Impacts of shared mobility on vehicle lifetimes and on the carbon footprint of electric vehicles
Authors: Morfeldt, J.; Johansson, D.
Journal: Nature Communications (2022)

Abstract
                  Shared cars will likely have larger annual vehicle driving distances than individually owned cars. This may accelerate passenger car retirement. Here we develop a semi-empirical lifetime-driving intensity model using statistics on Swedish vehicle retirement. This semi-empirical model is integrated with a carbon footprint model, which considers future decarbonization pathways. In this work, we show that the carbon footprint depends on the cumulative driving distance, wh

Authors: Li, X.; Zhu, Q.; Hong, Y.; Zheng, H.; Wang, J.
Journal: Nature Communications (2022)

AbstractMicro/nano electromechanical systems and nanodevices often suffer from degradation under electrical pulse. However, the origin of pulse-induced degradation remains an open question. Herein, we investigate the defect dynamics in Au nanocrystals under pulse conditions. By decoupling the electron wind force via a properly-designed in situ TEM electropulsing experiment, we reveal a non-directional migration of Σ3{112} incoherent twin boundary upon electropulsing, in contrast to the expected
Reversible Power-to-Gas systems for energy conversion and storage
Authors: Glenk, G.; Reichelstein, S.
Journal: Nature Communications (2022)

Abstract
                  In the transition to decarbonized energy systems, Power-to-Gas (PtG) processes have the potential to connect the existing markets for electricity and hydrogen. Specifically, reversible PtG systems can convert electricity to hydrogen at times of ample power supply, yet they can also operate in the reverse direction to deliver electricity during times when power is relatively scarce. Here we develop a model for determining when reversible PtG systems are economically via
