The Federal Republic of Germany and the United States (US) have adopted different models for energy federalism. Germany allocates more authority to the federal government and the US relies on a decentralized cooperative federalism model that preserves key roles for state actors. This article explores and compares the relevance of federal legal structures for renewable energy expansion in both countries. It sets out the constitutional, statutory, and factual foundations in both Germany and the US, and explores the legal and empirical dimensions of renewable energy expansion at the federal and state levels. The article concludes by drawing several comparative lessons about the significance of federal structures for energy transition processes.

South Africa faces interconnected challenges of developing and diversifying its economy and adapting to and mitigating the impacts of climate change. A green policy tilt is ascendant in the country, manifest in a cascading array of policies and special initiatives. Utilising concepts from the multi-level perspective on socio-technical transitions, we assess Africa's first designated Green Special Economic Zone (SEZ), Atlantis SEZ (ASEZ) in the Western Cape, a niche innovation aimed at transforming the Province's industrial base. This initiative is very ambitious in four respects: (1) it links green SEZ development in a deprived metropolitan area to the broader regional economy; (2) it utilises an innovative governance structure; (3) it promises localization economies and export potential; and (4) it connects SEZ niche experimentation with emergent renewable energy regimes. While elements are in place which might seed a sociotechnical transition, societal and political forces (i.e. landscape features) continue to limit its realisation, highlighting the immanent, structural realities shaping South Africa's economic futures.

Although the need for urgent climate change action is clear, insights about how to make better climate risk management decisions are limited. While significant attention from behavioral researchers has focused on choice architecture, we argue that many of the contexts for addressing climate risks require increased attention to the needs of a deliberative and dynamic choice environment. A key facet of this kind of decision is the need for decision-makers and stakeholders to identify and balance conflicting economic, social and environmental objectives. This recognition of difficult, context-specific trade-offs highlights the need for structuring the decision-making process so that objectives are clearly articulated and prioritized. Equally, policy analyses and deliberations must effectively link priorities with climate risk management options. This restructuring of decision-making about climate change calls for more than a nudge. Scientific and technical efforts must be redirected to help stakeholders and decision-makers better understand the diverse implications of climate change management alternatives and to become better equipped to take actions commensurate with the urgency of the problem.

Innovation is an important part of energy policy, and encouraging clean energy innovation is often an explicit goal of policy makers. For local governments, promoting clean energy innovation is seen not only as a pathway to a cleaner economy but also as a tool for promoting the local economy. But is such optimism warranted? There is a substantial literature examining the relationships between innovation and environmental policy, but few studies focus explicitly on innovation at the state and local level. In this paper, I provide key lessons from research on clean energy innovation, focusing on lessons relevant for state and local governments. I then summarize the results of a recent working paper by Fu et al. (2018) that studied wind energy innovation across individual states in the United States. While state-level policies can promote clean energy innovation, it is overall market size that matters most. Thus, innovation need not occur in those states most actively promoting clean energy. I conclude with lessons for state and local governments drawn from both this work and the broader literature on energy innovation.

In this article, we present a model of the electricity sector where generation technologies are intermittent. The economic value of an electricity generation technology is given by integrating its production profile with the market price of electricity. We use estimates of the consumer's intertemporal elasticity of substitution for electricity consumption while parameterizing the model empirically to numerically calculate the elasticity between renewables and fossil energy. We find that there is a non-constant elasticity of substitution between renewable and fossil energy that depends on prices and intermittency. This suggests that the efficacy and welfare effects of carbon taxes and renewable subsidies vary geographically. Subsidizing research into battery technology and tailoring policy for local energy markets can mitigate these distributional side effects while complementing traditional policies used to promote renewable energy.

Although a growing stream of research investigates the role of government in corporate social responsibility (CSR), little is known about how governmental CSR interventions interact in financial markets. This article addresses this gap through a longitudinal study of the socially responsible investment (SRI) market in France. Building on the “CSR and government” and “regulative capitalism” literatures, we identify three modes of governmental CSR intervention—regulatory steering, delegated rowing, and microsteering—and show how they interact through the two mechanisms of layering (the accumulation of interventions) and catalyzing (the alignment of interventions). Our findings: 1) challenge the notion that, in the neoliberal order, governments are confined to steering market actors—leading and guiding their behavior—while private actors are in charge of rowing—providing products and services; 2) show how governmental CSR interventions interact and are orchestrated; and 3) provide evidence that governments can mobilize financial markets to promote CSR.

There is evidence that the risk of stranded assets in the oil and gas sector is underpriced in financial markets. Publicly traded Western oil and gas companies are starting to write down assets, opening up the possibility that more rationalisation of value is likely to come. To the extent that large oil companies diversify portfolios to include cleaner energy and carbon sequestration technologies, it could reduce the risk of a sudden cascading change in the stock valuation of these firms and related bond and credit markets. Instead, the vast majority of oil and gas assets that will be stranded are in the control of sovereign states whose national budgets are highly dependent on oil and gas revenues. Thus, the problem of stranded asset risk for the oil and gas sector may be most relevant in markets for sovereign credit as well as risks that go beyond financial losses.

This study uses an econometric approach to investigate the role of IPR protection on renewable energy adoption using panel data of 102 countries at five-year intervals over the period 1990–2005. The Ginarte-Park index is used as a measure of the strength of intellectual property protection while the adoption of renewable energy is measured by the share of renewable energy in total final energy use. The results reveal that the level of intellectual property rights protection and reform of the intellectual property rights regime do not have significant impact on renewable energy adoption, suggesting that IPR protection is not a cause for concern in the global quest for clean energy transition. On the contrary, we find that trade openness has a stronger influence in the transition to clean energy. Based on the findings of the study, we conclude that IPR protection does not influence renewable energy adoption except in high R&D countries; rather policy makers should concentrate efforts on economic factors, such as trade openness, that drive the adoption of renewable energy technologies.

Fossil fuel sources are well suited to fulfill the energy needs of human beings. Unfortunately, there are some limitations and disadvantages pertaining to fossil fuels, some of which are drastic. The main issues are: firstly, there is a finite supply of these fuels, eventually this supply will be exhausted; secondly, burning fossil fuels contributes to global warming, leading to disastrous consequences for the environment and the health of humans. Switching to renewable energy sources is the viable solution to the aforementioned issues. Robots bring numerous benefits in a wide variety of applications. Introducing robots to production environments and other applications results in a remarkable improvement in terms of productivity and efficiency. In this paper, the integration between robots and renewable energy sources is discussed. In other words, two main points are investigated: (1) how can renewable energy be a viable source of energy for robots and (2) how can the renewable energy industry benefit from utilizing robots in the execution of renewable energy-related tasks. Some of the recent developments concerning the integration between robots and renewable energy are reviewed. In addition, more opportunities and expected advancements are also discussed.
