The Myth of Decarbonized Oil: Technological Fixes, Climate Delay, and the Politics of Low‐Carbon Fossil Fuels

open access: yesSustainable Development, EarlyView.
ABSTRACT The idea of “decarbonized oil” has become increasingly visible in climate, energy, and corporate transition debates as oil and gas actors seek to reconcile continued fossil fuel production with net‐zero commitments. This article offers a critical narrative review of the concept, asking what political work the idea of decarbonized oil performs ...

Investigation of the Evolution Mechanism and Multiphysics Coupling in Tree‐Contact Single‐Phase‐to‐Ground Fault

open access: yesHigh Voltage, EarlyView.
ABSTRACT Tree‐contact single‐phase‐to‐ground fault (TSF) is a common and hazardous type of failure in distribution networks. TSF is likely to occur when overhead conductors contact moist tree branches, potentially leading to insulation breakdown, posing serious threats to grid safety.
