AI adoption induces divergent net energy changes across economic sectors
Wei He, Daoping Wang, Hanqi Yan +2
Energy planning for artificial intelligence focuses on data-centre electricity, missing the induced operational energy change caused by the deployment of AI in commercial buildings…
Cycle-resolved explainability of energy storage impacts on whole-system cost and emissions
Zenghui Zhang, Wei He
Grid-scale storage is not intrinsically cost-reducing or emissions-reducing: whether a storage cycle lowers or raises whole-system cost and CO2 depends on when, where, how long, wh…
Food-Embedded Cold Energy Flows in Decentralised Solar Cold Chains
Hange Lao, Binjian Nie, Wei He
Reliable cold storage is needed to reduce meat loss in informal food systems, but conventional cold-chain expansion is difficult where electricity supply is weak and battery-based…
Compound effects of traffic and climate on electric vehicle HVAC energy consumption: a spatiotemporal framework with city-level attribution
Liang Zhang, Wei He
Real-world electric vehicle (EV) energy consumption can deviate by 20-40% from rated values, driven by ambient temperature, traffic congestion, and route characteristics. Existing…
Assess Space-Based Solar Power in European-Scale Power System Decarbonization
Xinyang Che, Lijun Liu, Wei He
Meeting net-zero targets remains formidable as terrestrial renewables grapple with intermittency and regional variability. Here, we integrate space-based solar power (SBSP) -- a po…
