In Aesop's fable, a swift hare races with a deliberate tortoise. In the end, the tortoise wins by taking a slow and steady approach. The authors argue that, given the economic constraints on US deployment of nuclear power, a "tortoise strategy" is more prudent for US government nuclear R&D efforts.

There is a sharp boundary between basic and applied research in the organizational structure of the US Department of Energy (DOE). In this work, the authors consider a branch of DOE that was designed to operate across this boundary: the Advanced Research Projects Agency — Energy (ARPA-E). They hypothesize that much of energy research cannot be neatly categorized as basic or applied and is more productive outside of the confines of the basic/applied dichotomy; ARPA-E provides an opportunity to test that hypothesis.

Solar photovoltaic (PV) electricity generation can greatly reduce both air pollutant and greenhouse gas emissions compared to fossil fuel electricity generation. The Chinese government plans to greatly scale up solar PV installation between now and 2030. However, different PV development pathways will influence the range of air quality and climate benefits. Benefits depend on how much electricity generated from PV is integrated into power grids and the type of power plant displaced. Using a coal-intensive power sector projection as the base case, the authors estimate the climate, air quality, and related human health benefits of various 2030 PV deployment scenarios.

China’s attempts to protect its access to energy supplies, particularly oil, are a rational strategy to shield itself from energy disruptions, particularly U.S. attempts to coerce China by constricting its oil supply.

Electrification with decarbonized electricity is a central strategy for carbon mitigation. End-use electrification can also reduce air pollutant emissions from the demand sectors, which brings public health co-benefits. In this article, the authors focus on electrification strategies for China, a country committed to both reducing air pollution and peaking carbon emissions before 2030. Considering both coal-intensive and decarbonized power system scenarios for 2030, they assess the air quality, health, and climate co-benefits of various end-use electrification scenarios for the vehicle and residential sectors relative to a non-electrified coal-intensive business-as-usual scenario.

On 21 May 2014, during a state visit by President Vladimir Putin to Beijing, China and Russia signed a $400 billion, 30-year gas deal. Under this agreement, China will import 38 billion cubic metres of natural gas from Russia’s Gazprom, beginning in 2018. Why, after 15 years of stalemated negotiations, did this breakthrough occur in 2014? Why did a natural, symbiotic gas relationship not develop earlier and more gradually? Most studies explain this by looking at Russia’s international isolation post Ukraine. Based on interviews with both Chinese and Russian officials this article argues the following: domestic incentives, rather than foreign-policy pressures, are the real force behind the timing of Sino–Russian energy breakthroughs in 2014.

For decades, fears of energy scarcity drove American energy diplomacy. The dependence of the global economy on oil, and America’s need to secure ever-growing quantities of this commodity, underpinned complex networks of alliances and intensive diplomatic endeavors. An atmosphere of ever-increasing global competition for resources made these labors all the more urgent and highstakes. Today, in an age of energy abundance, many anticipate that the new US energy prowess will render such efforts obsolete and pave the way for US disengagement in the world. Yet a sober look at reality suggests that this should be far from the case.

This study investigates whether, as part of a broader “Asian Energy Pivot,” Russia’s energy giant Gazprom refashioned its export strategy away from Europe, and what impact such a reorientation might have on the EU–Russia gas relationship. It uses four empirical cases to emphasize the domestic movers underlying Russia’s eastward shift in energy trade, developing a constructivist theory rooted in the dynamics of Russia’s dominant public narrative and the contours of domestic politics. It argues that Russia’s national interests changed as a result of how Russian policy-makers interpreted and reacted to the stand-off with Europe, in response to what they perceived as Europe’s attempt to isolate it economically and geopolitically. 

Many economists have long held that carbon pricing—either through a carbon tax or cap-and-trade—is the most cost-effective way to decarbonize energy systems, along with subsidies for basic research and development. Meanwhile, green innovation and industrial policies aimed at fostering low-carbon energy technologies have proliferated widely. Most of these predate direct carbon pricing. Low-carbon leaders such as California and the European Union (EU) have followed a distinct policy sequence that helps overcome some of the political challenges facing low-carbon policy by building economic interest groups in support of decarbonization and reducing the cost of technologies required for emissions reductions. However, while politically effective, this policy pathway faces significant challenges to environmental and cost effectiveness.

Enormous growth in solar photovoltaic (PV) electricity generation in China is planned, with a goal to provide 10 perecnt of total electricity demand by 2030. However, over much of China, aerosol pollution scatters and absorbs sunlight, significantly reducing surface solar radiation suitable for PV electricity generation. The authors evaluate the impact of aerosols on PV generation and find aerosol-related annual average reductions in eastern China to be more than 20 percent. In winter, aerosols have comparable impacts to clouds over eastern provinces. Improving air quality in China would increase efficiency of solar PV generation. As a positive feedback, increased PV efficiency and deployment would further reduce air pollutant emissions as well.
