The Clean Energy Dilemma in Asia: Is There a Way Out?

A prominent American geographer and specialist on energy and environmental policies in developing countries assesses the challenge to sustainable development posed by Asia's rapid economic growth and the concurrent need to reduce the environmental impacts of energy production and use. A particular focus is on China and India, as rapidly growing energy consumers and greenhouse gas emitters, and on Russia as a potentially important supplier of natural gas and liquid alternatives to coal use. The author suggests some elements of a strategy to resolve the dilemma of reducing global environmental impacts without penalizing Asia's economic development, although a significant energy transition over the next several decades appears quite difficult.     

India's Energy Security: Challenges and Opportunities

A noted specialist on India's energy security reviews the range of energy-related issues that will have a bearing on that country's ability to sustain the high current rates of economic growth and development into the future. The author explores the multiple challenges India confronts in securing (through domestic production and external sources) an adequate mix of energy supplies (hydrocarbon fuels, nuclear power, renewable energy sources) and describes as well as analyzes a broad front of actions (both government programs and the activities of private companies) taken to address them. The analysis illuminates India's important role in the production and consumption of several forms of energy.

Renewable Energy Politics: Policy Typologies,Policy Tools,and State Deployment of Renewables

This paper investigates the competing forces driving the development of renewable energy in the American states. We formulate a framework of state renewable energy politics and develop a set of hypotheses regarding the role of politics, policies, and prices in renewable energy development. We test these hypotheses with a fixed effect vector decomposition model using a panel data set for the U.S. states from 1990 to 2008. The results indicate that renewable energy development is influenced by regulatory institutions, the party affiliations of the governor and legislators, and the professionalism of the legislature, accompanied by the effects of various policy instruments.     

The Implications of Policy Stability for Renewable Energy Innovation in the United States, 1974–2009

Government support and commitment are of particular importance for renewable energy technology innovation activities, which are highly contingent on policy and market uncertainty. The research focus of this article is to examine the relationship between policy stability in public resource allocation and policy outcomes in renewable energy technologies. With time‐series cross‐sectional analyses, we test effects of both the stability and magnitude of federal R&D expenditures on patent applications in five renewable energy sectors (i.e., solar, wind, hydropower, geothermal, and bioenergy) from 1974 to 2009. The findings show that technology innovation is affected by both the magnitude and stability of government financial commitment. Nevertheless, when industries perceive government support over longer time frames, the magnitude effect loses explanatory power to the stability effect. In addition to federal R&D expenditures, policies pertaining to technology commercialization and marketization are a critical determinant of innovation activities. This study demonstrates that incremental, predictable, and credible expenditures facilitate renewable energy technology development. Conversely, a boom‐bust cycle of resource support fails to translate policy goals into intended results.     

Thermodynamic study of capillary pressure curves based on free energy minimization

This paper presents a new method for pore level network simulation of the distribution of two immiscible phases in a permeable medium. The method requires that the Helmholtz free energy of the system — the medium and the two phases contained within the pore space — be a minimum at all saturation states. We describe the method here and show some typical results from a computer algorithm that implements it. The results include (i) an explanation of the ‘scanning’ behaviour of capillary pressure curves based wholly on the free energy minimization, (ii) predictions of capillary pressure at arbitrary wetting states, including negative capillary pressures, and (iii) illustrations of how the minimized free energy changes along the scanning curves. The method also predicts the known dependency of the capillary pressure on the pore size distribution and interfacial tension. The current work is restricted to two‐dimensional networks, but the free energy minimization appears to be generalizable to three dimensions and to more than two fluid phases. Moreover, functions generated through the minimization, specifically contact areas between the medium surface and the phases, appear to have applications predicting other multiphase petrophysical properties.

Explaining Advocacy Coalition Change with Policy Feedback

Despite the prominence of exogenous factors in theories of policy change, the precise mechanisms that link such factors to policy change remain elusive: The effects of exogenous factors on the politics underlying policy change are not sufficiently conceptualized and empirically analyzed. To address this gap, we propose to distinguish between truly exogenous factors and policy outcomes to better understand policy change. Specifically, we combine the Advocacy Coalition Framework with policy feedback theory to conceptualize a complete feedback loop among policy, policy outcomes, and subsequent politics. Aiming at theory-building, we use policy feedback mechanisms to explain why advocacy coalitions change over time. Empirically, we conduct a longitudinal single case study on policy-induced technological change in the German energy subsystem, an extreme case of policy outcomes, from 1983 to 2013. First, using discourse network analysis, we identify four patterns of actor movements, explaining coalition decline and growth. Second, using process tracing, we detect four policy feedback mechanisms explaining these four actor movements. With this inductive mixed-methods approach, we build a conceptual framework in which policy outcomes affect subsequent politics through feedback mechanisms. We develop propositions on how coalition change and feedback mechanisms explain four ideal-typical trajectories of policy change.
