Enabling a Significant Nuclear Role in China’s Decarbonization

| Dec. 02, 2021

While China is building nuclear reactors faster than any other country in the world, major constraints may limit nuclear energy’s ability to grow to the scale of hundreds of gigawatts that would be required for it to play a major part in decarbonizing China’s energy system. This chapter explores the major constraints on, and risks of, large-scale nuclear energy growth in China, and how both new policies and new technologies might address them. It focuses particularly on the two biggest constraints – economics and siting. Substantial government policies to support nuclear power and advanced reactor systems designed to address some of the key constraints are both likely to be needed for nuclear to have a chance of playing a major role in decarbonizing China’s energy system; nuclear energy’s role may be bigger in the second half of this century than in the first half.

Avoiding a Plastic Pandemic: The Future of Sustainability in a Post COVID-19 World

| January 2021

The ongoing COVID-19 pandemic is upending our lives and the global economy in ways unimaginable until recently. While the overall impacts are still difficult to quantify, ramifications are sure to be felt for decades to come. Providing secure, reliable, and affordable resources for all without causing devastating environmental consequences is perhaps the greatest challenge of the 21st century. But the pandemic has significantly altered dynamics and changed priorities. How is this impacting the quest for sustainability?

In this paper we analyze these challenges by focusing on the plastic industry. There is no doubt that plastic has molded society in many ways that make our lives easier and safer, but it has also created a global environmental and sustainability crisis. In order to curb our addiction to plastic, the world had been waging a war against virgin plastic, but the pandemic has turned an enemy into a much-needed ally. How can we leverage the advantages of plastic without contributing to the world’s environmental crisis? This dilemma poses a significant challenge, but also opens an opportunity to address sustainability at a systemic level through circularity and the transition to low-carbon alternatives to petroleum-based plastics.

A History of the Energy We Have Consumed

| June 18, 2018

Early in Richard Rhodes’s new book, “Energy: A Human History,” we hear of a prominent citizen using colorful language to lament the state of his polluted city and urge his government to shut down industry or move it elsewhere: “If there be a resemblance of hell upon earth, it is in this volcano [on] a foggy day.” Though this could easily apply to modern-day Beijing, the speaker here is John Evelyn, a wealthy horticulturalist and one of the founders of the scientific Royal Society of London — and he’s complaining about London in 1659.

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.

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."

The Experts on Nuclear Power and Climate Change

| December 17, 2015

"Chinese President Xi Jinping reaffirmed at the global climate change conference in Paris that China pledged to achieve peak carbon dioxide emissions by around 2030, and to get around 20 percent of its primary energy from non-fossil sources by 2030. In 2014, China’s non-fossil energy consumption accounted for 11.2 percent of total energy use—hydro power was 8 percent, nuclear power was about 1 percent, and non-hydro renewable energy was around 2 percent—which is very close to the target of 11.4 percent set for 2015. Still, coal supplied the majority (66 percent) of China's total energy consumption in 2014, and oil accounted for about 18 percent of the energy mix. Natural gas, at 5 percent, still accounted for a relatively small share. To double the share of non-fossil sources by 2030, what role can nuclear power play?"
