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.

Sovereign Wealth Funds in Small Open Economies

| Apr. 24, 2018

The small open economies of the Gulf and Southeast Asia are pioneers in the establishment of

Sovereign Wealth Funds (SWFs). The SWFs of countries like Qatar and Singapore are among the

world’s largest in terms of total asset size relative to Gross Domestic Product. This article looks

at the different compulsions behind the setting up of SWFs by small open economies.

Towards Sustainability in Water-energy Nexus: Ocean Energy for Seawater Desalination

In this article, the authors review the state of the art of ocean energy in desalination. It explores different sources of energy from the ocean that include electricity generation, as well as mechanical force and thermal energy and salinity gradients that can also be directly harnessed for powering the desalination processes. They also examine recent advances in scaling up for commercial deployment and discuss relevant cost, environmental, and social concerns.

U.S. Ambassador To India Richard Verma Leaves A Lasting Legacy To Follow

| Feb. 03, 2017

Richard Verma’s two-year tenure as U.S. Ambassador to India concluded last month with the new incoming presidential administration. During his time in New Delhi, Verma established himself as one of the most consequential envoys to ever occupy the prestigious post once held by such foreign policy legends as John Kenneth Galbraith and Frank Wisner. The first Indian American to serve in the role, Verma leaves behind a far-reaching legacy. He raised the U.S-India strategic partnership to unparalleled heights in virtually every arena of bilateral cooperation while serving as a skilled and talented public diplomat.

Using Inclusive Wealth for Policy Evaluation: Application to Electricity Infrastructure Planning in Oil-Exporting Countries

| 2017

Decision-makers often seek to design policies that support sustainable development. Prospective evaluations of how effectively such policies are likely to meet sustainability goals have nonetheless remained relatively challenging. Evaluating policies against sustainability goals can be facilitated through the inclusive wealth framework, which characterizes development in terms of the value to society of its underlying capital assets, and defines development to be potentially sustainable if that value does not decline over time.

A Few Thoughts on Engineering Peaceful and Inclusive Societies

| November 3, 2016

"The rise of nations such as South Korea, Singapore and China as global economic players illustrated the importance of expanding and deepening human competence. A key starting point in the growth process is recognising that building engineering capabilities offered the best opportunity for technological leapfrogging and catch-up in a variety of industries."

Energy decisions reframed as justice and ethical concerns

| 6 May 2016

Many energy consumers, and even analysts and policymakers, confront and frame energy and climate risks in a moral vacuum, rarely incorporating broader social justice concerns. Here, to remedy this gap, we investigate how concepts from justice and ethics can inform energy decision-making by reframing five energy problems — nuclear waste, involuntary resettlement, energy pollution, energy poverty and climate change — as pressing justice concerns.

Steps to China's Carbon Peak

| June 18, 2015

China is the world's largest emitter of carbon dioxide, accounting for one-quarter of the global total in 2013. Although the country has successfully lowered the rate of emissions from industry in some cities through improved technology and energy-efficiency measures, rapid economic growth means that more emissions are being added than removed. Without mitigation, China's CO2 emissions will rise by more than 50% in the next 15 years.
