Increase in Frequency of Nuclear Power Outages Due to Changing Climate

| July 05, 2021

Climate-related changes have already affected operating conditions for different types of energy system, in particular power plants. With more than three decades of data on changing climate, we are now in a position to empirically assess the impact of climate change on power plant operations. Such empirical assessments can provide an additional measure of the resilience of power plants going forward. Here I analyse climate-linked outages in nuclear power plants over the past three decades. My assessment shows that the average frequency of climate-induced disruptions has dramatically increased from 0.2 outage per reactor-year in the 1990s to 1.5 in the past decade. Based on the projections for adopted climate scenarios, the average annual energy loss of the global nuclear fleet is estimated to range between 0.8% and 1.4% in the mid-term (2046–2065) and 1.4% and 2.4% in the long term (2081–2100).

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.

Nuclear Disarmament, Nuclear Energy, and Climate Change

| March 2019

Preventing nuclear war and avoiding catastrophic climate change are two of the most basic challenges facing human civilization in the twenty-first century. While these are separate issues, these challenges are linked in several ways, and both may be affected by the future of nuclear energy. For nuclear energy to provide any substantial part of the low-carbon energy needed in the second half of the twenty-first century would require dramatic growth. This chapter provides an overview of the constraints and risks of nuclear energy growth on that scale, and the necessary steps to address them. In particular, use of nuclear energy at that scale would place unprecedented demands on global systems for verification, control, and security for weapons-usable nuclear materials. Deep reductions in nuclear arms and their eventual prohibition will also require new approaches to managing the vast global stocks of weapons-usable nuclear materials. Politically, nuclear energy may not be able to grow on the scale required unless governments and publics are confident that it will not contribute to the spread of nuclear weapons, creating another link between climate mitigation and nuclear nonproliferation and disarmament.

US Nuclear Power: The Vanishing Low-carbon Wedge

Nuclear power holds the potential to make a significant contribution to decarbonizing the US energy system. Whether it could do so in its current form is a critical question: Existing large light water reactors in the United States are under economic pressure from low natural gas prices, and some have already closed. Moreover, because of their great cost and complexity, it appears most unlikely that any new large plants will be built over the next several decades. While advanced reactor designs are sometimes held up as a potential solution to nuclear power's challenges, the authors' assessment of the advanced fission enterprise suggests that no US design will be commercialized before midcentury. That leaves factory-manufactured, light water small modular reactors (SMRs) as the only option that might be deployed at significant scale in the climate-critical period of the next several decades.

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.
