As two indispensable resources for human development, energy and water are closely related. China, as the world's largest consumer of electricity, is also experiencing very serious water shortages. Understanding the water consumption intensity in various types of electric power production technologies according to China's national conditions is a prerequisite for understanding the potential impact of electrical power production on water resources. Therefore, following the steps of a meta-analysis, this paper provides a literature review on operational water withdrawal and consumption factors for electricity generation technology in China. We observed that 50% of water consumption for electricity generation was for coal power, whereas there was no research on the water consumption intensity of natural gas power generation, and a shortage of studies on water intake during electrical power production. The average water consumption intensity of hydropower is the largest. The results indicate that compared with other fuel types, hydropower is not a sustainable energy with respect to water conservation, and the study of hydropower applications should be improved in China.
To improve conference management and realize self-served control by users, this paper proposes a specific design of tablet-based control software on video conference, incorporating demands of video conference systems in State Grid Corporation of China (SGCC). The software has been designed and implemented with studies on the system structure and key technologies as the bedrock. With in-depth analysis on various operations’ frequencies, streamlined interface, and exquisite designs, the software enables users to independently control regular conferences without on-site professional technicians. Moreover, it meets different demands for different scenarios, such as for public conference room and normalized management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
