How to Globalize Clean Energy

| June 20, 2020

The authors argue that more determined efforts to globalize renewable energy transmission can confer significantly higher economic and environmental benefits from renewables on billions of people. This can be done by exploiting spatial differences between electricity loads and net renewable generation across time zones (temporal arbitrage) and latitude (seasonal arbitrage). Using very long distance, ultra-high voltage (UHV) transmission infrastructure, temporal and spatial arbitrage can move low-cost clean electricity from areas with excess capacity to high demand zones in other countries and even continents.

Urban Waste to Energy Recovery Assessment Simulations for Developing Countries

In this paper, a quantitative Waste to Energy Recovery Assessment (WERA) framework is used to stochastically analyze the feasibility of waste-to-energy systems in selected cities in Asia.

Deploying coal-bioenergy gasification systems with carbon capture and storage (CBECCS) provides a promising opportunity for China to realize its carbon mitigation and air pollution abatement goals simultaneously. The authors conducted a comprehensive assessment of CBECCS technology for China, with a focus on plant and fuel configurations (e.g., biomass ratios) and economics, as well as CO2 and greenhouse gas emissions and cobenefits for air quality.

China's Calculus After the INF Treaty

| May 08, 2019

It seems that the Intermediate-Range Nuclear Forces (INF) Treaty is coming to an end. The Treaty prohibits the United States and Russia from possessing, producing or testing land-based ballistic and cruise missiles with ranges of 500–5500 kilometres, including both conventional and nuclear-armed missiles. On 1 February 2019, US President Trump said that he would suspend obligations under the INF Treaty and initiate the withdrawal procedure. After withdrawing, the United States might deploy conventional and nuclear missiles to the West Pacific against China. How would the potential deployment of each missile type impact China’s security?

Stochastic Cost-benefit Analysis of Urban Waste-to-Energy Systems

Municipal solid waste generation is a rapidly increasing challenge that is leading to severe pollution and environmental degradation in many urban areas of developing countries. This study presents the Waste to Energy Recovery Assessment (WERA) framework, a new quantitative decision support model for initial evaluation and alternative comparisons of different thermochemical treatments of municipal wastes. The framework is used to study waste-to-energy (WtE) systems for Abu Dhabi, Riyadh, Tokyo, and New York. The results show that WtE systems can fulfill only 1.4–3.6% of 2014 electricity demand in the analyzed cases.

The Future of the Nuclear Order

| April 2019

Foreign policy pundits have bemoaned the unraveling of the post-World War II international order in recent years, describing threats to the multilateralism and liberalism enshrined in postwar institutions. An often overlooked component of that structure is the global nuclear order, which, like other parts of the postwar system, was created for magnanimous and selfish aims: reducing the dangers of nuclear weapons for all and serving the interests of the world’s most powerful states.

Dim Hope for Disarmament and Approaching Risk of Build-Up

| March 2019

Further nuclear reduction under the current regimes seems unlikely. The US argues that Russia has violated the INF Treaty by developing and deploying a land-based cruise missile. Russia also makes the accusation that the Aegis Ashore missile defense system in Europe, capable of launching cruise missiles, has violated the INF. Furthermore, President Trump has repeatedly expressed his unwillingness to extend the New START Treaty for five more years after it expires in February 2021. The US-Russia bilateral disarmament process seems to have terminated. There have been some signs of nuclear build-up. The new US Nuclear Posture Review emphasizes the role of nuclear weapons while de-emphasizing strategic stability, reduces the threshold for nuclear use and calls for developing new low-yield SLBM and sea-launched cruise missiles. America’s nuclear policy might stimulate Russia and China to build new nuclear capabilities. North Korea’s advances in nuclear and long-range missile programs justify Washington’s investment in homeland missile defense, which in turn undermines China and Russia’s nuclear retaliatory capability and might result in a defense-offense arms race.

Can This New Approach to Nuclear Disarmament Work?

| Jan. 23, 2019

An estimated 14,485 nuclear weapons exist on earth today — most are far more powerful than those that twisted railway ties, leveled buildings, and crushed, poisoned, and burned human beings in Hiroshima and Nagasaki. The majority of these weapons belong to the United States and Russia. For some in the U.S. government, including Chris Ford, assistant secretary at the State Department’s Bureau of International Security and Nonproliferation, this number represents significant disarmament progress since Cold War highs of over 70,000 nuclear weapons. They argue the current security environment means that further reductions are not possible at this time. In contrast, for many disarmament advocates and officials from non-nuclear weapons states, this number is still far too high. They are now clamoring to ban all nuclear weapons. Because of this divide, according to Ford, we currently face a “disarmament crisis.”

Electric Vehicle Recycling in China: Economic and Environmental Benefits

    Authors:

| January 2019

With the rapid growth of electric vehicles in China, their benefits should be scientifically identified to support the industry development. Although the life cycle benefits of electric vehicles have been analyzed worldwide, the recycling phase has not been fully studied yet, especially in China. Therefore, this study focuses on the economic and environmental benefits of electric vehicle recycling in China. Based on the technology adopted by leading enterprises, the gross income and reduction of energy consumption and greenhouse gas emissions are calculated to reveal the benefits.

BTS, the "Atomic Bomb Shirt," and South Korean Attitudes Toward Nuclear Weapons

| Nov. 19, 2018

Over the past few weeks, BTS members have found themselves entangled in a bizarre scandal over an “atomic bomb shirt” that led to the cancellation of their appearance on a popular TV Asahi music show in Japan, which has been the main foreign source of revenues for K-pop groups since the 1990s. The 23-year-old singer, Jimin, was caught on the street wearing a white t-shirt bearing the slogan “Patriotism Our History Liberation Korea” repeated in numerous lines and overlapped by a black-and-white picture of the mushroom cloud from the atomic bomb that the United States detonated over Nagasaki, Japan on August 9, 1945.
