Social energy supplies require stability, controllability and adjustability," said Xiang Haiping, chief engineer of the National Energy Administration.

According to Pan, the biggest difficulty with aquaculture lies in its unpredictability and lack of controllability.

"New energy such as wind and solar power, although produce low carbon emission in use, are of obvious drawbacks - intermittency, volatility and inconsistency; while social energy supplies require stability, controllability and adjustability," said Xiang Haiping, chief engineer of the National Energy Administration.

China is stepping up efforts in innovation breakthroughs in the medical devices sector in a bid to enhance the independence and controllability of industrial and supply chains.

The directive addressed eight tenets－harmony and friendliness, fairness and justice, inclusiveness and sharing, respect for privacy, security and controllability, shared responsibility, open cooperation and agile governance.

The technology is designed to help staff members at locations with high-density passenger flow, such as train stations, bus stations, metro stations and airports, to rapidly identify people who may have abnormal body temperatures without close physical contact, improving passing efficiency and controllability in open places.

Internal pilot tests have been conducted in locations including Shenzhen, Guangdong province; Suzhou, Jiangsu province; the Xiongan New Area in Hebei province; and Chengdu, Sichuan province to check the theoretical reliability, system stability, convenience, applicability and risk controllability of the digital currency, Yi said.
