We provide a summary of the progress all 53 assessed components describing global alignment with Net Zero Emissions by 2050 Scenario (NZE) International Energy Agency (IEA), an intermediate trajectory scope 2030. The (grouped in eight categories) cover sectors (such as Transport, and Buildings), subsectors Aviation, Building Envelopes), technologies Biofuels, Electrification), infrastructure cross-cutting strategies CO2 Transport Storage, Electrolyzers). For each component, IEA assigned one three qualitative levels; namely “On track”, “More efforts needed”, or “Not on track”. IEA’s assessment results were made publicly available form online web-based report, titled “Tracking Clean Progress”, TCEP, which was published 12/July/2023. Out TCEP’s components, only rated these are (1) Solar Photovoltaic (PV), (2) Electric Vehicles (EV), (3) Lighting. remaining 50 TCEP; 28 22 propose quantitative aggregate numerical score to describe overall clean energy transition reflected TCEP we compute it 2.23/4 (or 55.7%). Finally, present selected historical records (based data) about satisfactory for transition.

The detection of sudden faults in wind turbine generator (WTG) is a complex task, especially bearings. Usually, the evaluation methodologies such as vibration, ultrasound, and bearing temperatures are widely used predictive maintenance, an important aspect for traditional approach, fault detection, limited analysis with single variable or temperature. For instance, these sensors detect 5–20% torsional vibration drivetrain 55% has failure due to lubricant problem, 20% solid contamination 9% incorrect application bearing. Consequently, solve this limitation failures modes, research evaluated limits focused on early generators; it utilized multi-stage approach involving Random Forest, XGBoost, Light XGB, Logistic Regression, followed by probability scores optimal features search grid validation, addition, validated results through finite element modeling, Boroscopy, analysis. Hence, database considers bearings, gearboxes, normal operation; regarding 8,711,808 samples validating process. result study five days before high classification accuracy 99.994%, recall 99.982%, F1 score 98.124%, kappa 99.330%, test set time 22.82 s. This new provides compared bearings gearboxes.
