Russia's 2022 invasion of Ukraine illuminated the long profound shadow of nuclear weapons over international security. Russia's nuclear threats have rightfully garnered significant attention because of the unfathomable lethality of nuclear weapons. However, the use of such weapons in Ukraine is only one way—albeit the gravest— that Russia could challenge the global nuclear order. Russia's influence extends deep into the very fabric of this order—a system to which it is inextricably bound by Moscow's position in cornerstone institutions such as the Nuclear Non-Proliferation Treaty (NPT) and the International Atomic Energy Agency (IAEA). From withdrawing from key treaties to stymieing resolutions critical of misconduct, Moscow has demonstrated its ability to challenge the legitimacy, relevance, and interpretations of numerous standards and principles espoused by the West.

How can electricity sector policymakers in developing countries ensure financial viability of utilities while also extending electricity access and minimizing the environmental impact of electricity supply? This study uses a mixed-method approach to analyze synergies and trade-offs between policies for financial reform of utilities, extending electricity access, and solar PV deployment in the case of Uttar Pradesh in India.

The world has grown more dangerous but also less open to arms control measures that could limit some of the dangers. What can be done? Steven E. Miller offers a tour de force overview of both dismal and hopeful trends within arms control over the past decades, in this first paper of a new HCSS series on Arms Control.

How can China make good on its pledge to reach carbon neutrality by 2060? In Foundations for a Low-Carbon Energy System in China, a team of experts from China and the United States explains how China's near-term climate and energy policies can affect long-term decarbonization pathways beyond 2030, building the foundations for a smoother and less costly national energy transformation.

This article examines both the premise and prescription of the argument to integrate renewable electricity in developing countries through elements of the standard model (such as a wholesale spot market, or an independent system operator for dispatch). This is done by highlighting the differences between power sector reform experiences in the developing and developed worlds, and the causal mechanisms underlying these differences.

In the authors' view, neither formal NATO membership nor nuclear weapons are fitting security options for Ukraine in the face of Russian aggression. To secure its borders and achieve sustainable peace and stability in Europe, Ukraine should forge a treaty-based strategic alliance directly with the United States.

Daniel Schrag argues that in order to reestablish the United States as a serious partner in addressing global climate change, the president must make good on the original standards of the Paris Agreement.

In recent years, NATO has begun to incorporate some innovative new cyberwarfare games and exercises into its annual wargames. But there is something missing. If NATO wants to see what nation-state hacking is like in the chaotic multiactor online world, it needs to practice fending off some actual hackers.

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.

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.
