A large part of operating costs in urban water supply networks is usually due to energy use, mostly in the form of electricity consumption. There is growing pressure to reduce energy use to help save operational costs and reduce carbon emissions. This study shows how a hybrid linear and multi-objective optimization approach can be used to identify key energy consumption elements in a water supply system, and then evaluate the amount of investment needed to achieve significant operational gains at those points in the supply network.

This paper argues that these potential vulnerabilities deserve rigorous, urgent, and thorough investigation. First, it draws from cybersecurity literature, and reviews general sources of vulnerability in digital systems. Next, with these sources of vulnerability in mind, it reviews the health intelligence systems used in the US as well as in a current Public Health Emergency of International Concern (PHEIC), the Ebola outbreak in the Democratic Republic of the Congo (DRC). It then It then reviews the possible motives state actors have to attack health intelligence systems, drawing on recent examples of state-led efforts to manipulate, conceal, or undermine health information. It then speculates about what an attack on a health intelligence system might look like. It concludes by proposing a research and education agenda to thoroughly interrogate these issues and generate policy recommendations needed to address them.

In this report, the authors conduct a benchmarking analysis for energy and CO2 emissions intensity of the steel industry among the largest steel-producing countries.

Cement production is one of the most energy-intensive and highest carbon dioxide (CO2) emitting manufacturing processes. The goal of this study is to develop a roadmap for decarbonization of California's cement and concrete production. In this study, the authors look at the current status of cement and concrete production in California and develop scenarios up to 2040 to analyze different decarbonization levers that can help to reduce CO2 emissions of cement and concrete production in California.

The authors explain how the risks of computer systems are transferring to biological systems. The difference is that biological systems have the potential to cause a greater degree of damage than computer systems. Stringent biocontainment helps, but no containment system provides zero risk.
