The global energy industry is transforming as governments invest in clean energy technologies to address climate change, enhance energy security, and strengthen national competitiveness. Comparative research on clean energy transitions highlights the domestic drivers and constraints of clean energy transitions. This article contends that we need to understand the effects of global interdependence on clean energy transitions. Shifts in forms of interdependence between firms—influenced by the rise of global supply chains—have new implications for policy choices made by governments. Governments face more complex demands from domestic industries facing global economic competition, and act strategically in response to the actions of other governments, including sub-national actors, and firms in the global economy. We suggest that research on interdependence in clean energy transitions benefits from an analytical focus on mechanisms of transnational change such as cross-national and multi-level policy feedback and cross-national policy sequencing. Global interdependence has important implications for economic and environmental outcomes, affecting the durability of competitive advantage, and influencing the pace of the diffusion of clean energy technologies.

Technology costs and deployment rates, represented in experience curves, are typically seen as the main factors in the global clean energy transition from fossil fuels towards low-carbon energy sources. We argue that politics is the hidden dimension of technology experience curves, as it affects both costs and deployment. We draw from empirical analyses of diverse North American and European cases to describe patterns of political conflict surrounding clean energy adoption across a variety of technologies. Our analysis highlights that different political logics shape costs and deployment at different stages along the experience curve. The political institutions and conditions that nurture new technologies into economic winners are not always the same conditions that let incumbent technologies become economic losers. Thus, as the scale of technology adoption moves from niches towards systems, new political coalitions are necessary to push complementary system-wide technology. Since the cost curve is integrated globally, different countries can contribute to different steps in the transition as a function of their individual comparative political advantages.

Climate change mitigation relies increasingly on clean technologies such as renewable energy. Despite widespread success, further deployment of renewables has been met with resistance from voters and governments in several countries. How resilient is the renewable energy industry to adverse political events? I use the unexpected election of Donald Trump in the 2016 U.S. presidential race to study this question. As a vocal critic of renewables and a supporter of fossil fuels, his election is a plausible negative shock to the renewable energy sector. I examine stock market data to gauge the reaction of investors. I find that renewable energy stocks were adversely affected by the election. Overall, they experienced a cumulative abnormal loss in share values of about 6 percent on average over the twenty days that followed the election. However, I find that the negative effect is concentrated among non-U.S. firms. U.S. firms, on average, emerged unscathed. Non-U.S. companies, on the other hand, lost over 14 percent of their value in the aftermath of the election. This suggests that markets are more concerned by increasing obstacles to international business than a decrease of federal support for renewables.

As renewable energy supply chains have grown increasingly globalized, national clean energy transitions have become highly influenced by international dynamics. However, these dynamics are themselves collectively shaped by domestic policy that drives the deployment of renewables. While spatial spillovers of domestic renewable energy policies have been studied on an aggregate level regarding policy diffusion or the flows of technology across countries, implications on an actor-level have been largely neglected. This article addresses this gap by analyzing global patterns of market openings for wind, solar PV, and biomass, focusing on the role of private project developers in developing countries. We use a mixed method design, based on a newly merged dataset encompassing eighty countries, and on interviews with pioneering project developers. Results highlight how patterns in market openings are shaped considerably by technology characteristics. Further, empirical results show international private developers are a key first mover in many developing countries. We explore drivers for this internationalization trend, including the impact of international developers' home country policies and the accumulation of tacit knowledge from home country markets for market openings abroad. Finally, we discuss implications for industrial policy and argue for further research on global spillovers of national policies on the actor-level.

Governments support clean technologies to advance both environmental goals and national competitiveness. By adopting environmental policies early on, governments are argued to create durable competitive advantages for domestic companies that develop clean technologies for export to late adopters. This paper argues that policy competition between lead and follower markets conditions the ability of governments to create durable competitive advantages in low-carbon technologies. Depending on the complexity of the technology, we observe two patterns of green industrial policy competition. In low-complexity technologies, such as solar photovoltaics, follower markets are likely to adopt policies that support manufacturing capacity to rapidly achieve price advantages from economies of scale, with global supply chains intensifying this competition (“scaling up”). In high-complexity technologies, such as electric vehicles, follower markets are likely to adopt policies that support research and development to develop differentiated high-tech products for export (“innovating up”). We also suggest that new forms of interdependence in policy competition can affect the political sustainability of lead market policies. Competition in scaling-up is more likely to undermine political coalitions in favor of government support for low-carbon technologies, while innovating-up dynamics embed political coalitions that support lead market policies for low-carbon technologies.

When can complex multi-round environmental policymaking like that seen in climate be successful? An emerging branch of literature examines how sequencing matters to success and under what circumstances path dependent dynamics can lead to increasingly stringent climate and environmental policy. Here, I propose an industry typology that divides industry into four categories based on their relationship and likely response to early regulatory policy moves. I use a series of case studies that compare the application of this typology across issue areas internationally, looking comparatively at ozone and climate change policymaking; and subnationally across U.S. states in the climate change issue area. Using these case studies, I show how this model for understanding different mixes of industry type can help us understand and predict the likelihood of policy-industry feedback that leads to increasing environmental and renewable energy policy success over time, both at the international level and comparatively across national and sub-national jurisdictions.

In the field of business and politics, research on the role of business actors in individual fossil fuel industries that contribute to climate change has been sparse. At the same time theorising the role of ad hoc coalitions has been limited even though they appear to be an important vehicle for business actors seeking to shape contemporary policy contests. This paper attempts to address these understudied areas by drawing on a rich empirical dataset to examine the role of three ad hoc coalitions in the U.S. energy sector. In doing so, it builds on the existing literature to establish a theoretical basis for identifying the defining elements of ad hoc coalitions and the conditions under which business actors decide to establish them. Further, it sheds light on how business actors use ad hoc coalitions in three key fossil fuel industries—gas, oil, and coal—to shape policy outcomes, and in turn shape the path to a clean energy transition.
