Earlier sources: Energy
Energy research and engineering concern how power is produced, stored, delivered, and consumed. Follow solar and nuclear power, fusion, geothermal systems, batteries, electricity grids, and changing power demand.
SYMTRI organizes observations from public sources into a living map. Connections reflect shared subject matter; they do not establish causation or endorse a source.
Open in the map ↗665 classified signals in the fourteen-day window. Recent momentum: steady. These counts include signals awaiting readable evidence.
Earlier sources
Up to ten sources with readable evidence, ordered by their feed timestamp. These archive sources can be older than the live fourteen-day window. This list is a sample, not a measure of total activity. Dates distinguish paper publication, repository creation, model/dataset activity, Hacker News posts, and KEV catalog additions. “First archived” records when SYMTRI first stored the signal.

Effects of Structural and Electrical Defects on Vibration Suppression and Energy Harvesting Performance of Piezoelectric Metamaterial Beam ↗
This paper investigates the vibration suppression and energy harvesting performance of a locally resonant piezoelectric metamaterial beam (PMMB) with structural and electrical defects. The unit cell of a PMMB comprises a square aluminum substrate, two rubber plates sandwiching a piezoelectric plate, and a cylindrical stub on top. The structural and electrical defects are introduced by varying the material density of a stub, adjusting the spacing between the two adjacent piezoelectric local resonators (PLRs), and connecting inductors to selected PLRs, respectively. To investigate the theoretica…

Transient Responses of Avian Assemblages to Geothermal Drilling in Costa Rica ↗
Due to their requirements, geothermal projects are often located near volcanic activity that, in the tropics, overlaps with or lies close to conservation areas. It is therefore important to assess the environmental impact of these projects on biodiversity. We evaluated the impacts of well-drilling activities on bird communities at a geothermal field in Costa Rica. We hypothesized that (i) disturbance generated during drilling caused a temporary decline in bird diversity and abundance, followed by recovery once drilling noise ceased, and (ii) responses were species-specific, ranging from a nega…

Two-Fraction Kinetic Modelling of Methane Recovery and Energy Potential During Batch Anaerobic Digestion of Agricultural and Agro-Industrial Substrates ↗
Anaerobic digestion (AD) of agricultural and agro-industrial substrates depends on feedstock properties and degradation rate. Biochemical methane potential (BMP) gives the final methane potential, but it does not show how much methane is recovered within a given digestion time. A two-fraction kinetic model was used to estimate methane recovery and energy potential during batch digestion. The input data included total solids, volatile solids, experimental BMP, the shares of rapidly and slowly biodegradable fractions, their rate constants, and lag time. Ten substrates were assessed using archive…

Machine learning framework for short- and medium-term building energy consumption forecasting ↗
Accurate forecasting of building energy consumption is crucial for increasing energy efficiency, enabling demand-side management, and improving decarbonization efforts. However, building load profiles are highly variable, impacted by operational schedules, tenant behavior, and weather conditions, limiting the accuracy of conventional forecasting systems. This study rigorously compares six forecasting approaches—Long Short-Term Memory (LSTM), Artificial Neural Networks (ANN), k-Nearest Neighbors (KNN), Extreme Gradient Boosting (XGBoost), Autoregressive Integrated Moving Average (ARIMA), and Se…

The impact of financing cost differences on global energy and industry decarbonization ↗
Abstract Integrated assessment models usually neglect differences in financing conditions across countries, sectors and time. This omission could distort outcomes concerning electricity generation and also other sectors. Here we estimate and implement dynamic, country-specific cost of capital (CoC) for eight energy and industry sectors in the IMAGE integrated assessment model. Compared with assuming a uniform low-risk CoC, accounting for developing countries’ investment risks increases global mitigation costs through 2100 for staying well below +2 °C by around 9% and shifts cost-effective miti…

Blazar Variability as a Probe of Ultra-High-Energy Cosmic Rays and Very-High-Energy Gamma Rays: A Multi-Messenger Review Across All Timescales ↗
Blazars are variable at every timescale that has been observed, from minute-scale flares to secular trends spanning decades, and across the whole electromagnetic spectrum from radio to very-high-energy (VHE; Eγ≳100 GeV) γ-rays. This variability is not merely a nuisance to be averaged over: it is a time-resolved record of the physical conditions in the jet, and therefore a diagnostic of whether, and how, these sources accelerate particles to the highest energies. This review takes variability itself as its organizing principle. Rather than asking whether a particular blazar subclass accelerates…

Ultralow-temperature spin kinetics of strongly hybridized electro-nuclear excitations in LiHoF 4 ↗
Recent cavity-magnon-polariton (CMP) spectroscopy of the quantum Ising magnet LiHoF 4 represents a remarkable experimental achievement, providing high-fidelity baseline spectra of electro-nuclear spin transitions. However, the interpretation of these results using a standard single-ion mean-field theory (MFT) predictably falls short in describing many-body dynamic correlations, leaving several pronounced anomalies unexplained: double peaks of dissipation near the quantum critical point (QCP), bell-shaped transition linewidths, and the collectivization of discrete transitions below the critical…

Fault Diagnosis and Control Strategies in Photovoltaic Systems: Recent Advances in Reliability Improvement, Lifetime Extension, and Waste Reduction ↗
The continuous growth of photovoltaic (PV) installations worldwide has increased the need for reliable and sustainable energy conversion systems. Failures occurring in PV modules, power electronic converters, and control units can significantly reduce energy production, accelerate component degradation, and shorten system lifetime. This structured narrative review synthesizes the literature published primarily between 2015 and 2026, with particular emphasis on studies from 2020 to 2026; earlier publications are included selectively when they provide foundational or normative concepts relevant…

How to assess evidence about Energy
Check each original source for its methods, release status, limitations, and supporting data. A repository announcement, a preprint, and a published study provide different kinds of evidence. SYMTRI’s subject classification helps discovery; it does not independently validate the source’s claims.
