The End of Cyber-Anarchy?

| January/February 2022

Joseph Nye argues that prudence results from the fear of creating unintended consequences in unpredictable systems and can develop into a norm of nonuse or limited use of certain weapons or a norm of limiting targets. Something like this happened with nuclear weapons when the superpowers came close to the brink of nuclear war in 1962, during the Cuban missile crisis. The Limited Test Ban Treaty followed a year later.

Multi-objective Optimization of Energy and Greenhouse Gas Emissions in Water Pumping and Treatment

    Authors:

| 2020

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.

Deep Decarbonization Roadmap for the Cement and Concrete Industries in California

| September 2019

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.

Thirty-three Years Since the Catastrophe at Chernobyl: A Universal Lesson for the Global Nuclear Power Industry

| Apr. 25, 2019

The world will soberly commemorate the 33rd anniversary of the Chernobyl nuclear power plant catastrophic accident on Friday, April 26, 2019.  Some may wonder why bother with a gone-by historical event that happened in a distant land — a country that no longer exists — the former Soviet Union (now Ukraine).  On the contrary, Chernobyl and its legacy, with its specters of lingering human toll, radiation contamination, and the massive new shelter ("New Safe Confinement") installed over the old sarcophagus encasing the reactor, will be with us for a long time.
