Joseph A. Dammel, Jeffrey M. Bielicki, Melisa F. Pollak, and Elizabeth J. Wilson at the University of Minnesota Center for Science, Technology, and Public Policy have published a feature article titled “A Tale of Two Technologies: Hydraulic Fracturing and Geologic Carbon Sequestration” that appears in the online version of the science journal, Environmental Science & Technology [subscription required]. In comparing, contrasting, and analyzing the regulatory landscape governing the use of hydraulic fracturing and geologic carbon sequestration, they conclude that “A shift toward a 21st Century vision of regulation is required. Hydraulic fracturing and geologic sequestration are both technologies that could reduce...
This paper compares the incentives a carbon dioxide emissions price creates for investment in low carbon dioxide-emitting technologies in the electricity sector. We consider the extent to which operational differences across generation technologies – particularly, nuclear, wind and solar photovoltaic – create differences in the incentives for new investment, which is measured by the operating profits of a potential entrant. First, astylized model of an electricity system demonstrates that the composition of the existing generation system may cause electricity prices to increase by different amounts over time when a carbon dioxide price is imposed. Differences in operation across technologies therefore translate...
This article presents an application of a risk assessment approach in characterising the risks associated with safety violations in underground bituminous mines in Pennsylvania using the Mine Safety and Health Administration (MSHA) citation database. The MSHA database on citations provides an opportunity to assess risks in mines through scrutiny of violations of mandatory safety standards. In this study, quantitative risk assessment is performed, which allows determination of the frequency of occurrence of safety violations (through associated citations) as well as the consequences of them in terms of penalty assessments. Focus is on establishing risk matrices on citation experiences of mines, which can give early...
With increasing levels of wind generation capacity on electricity systems, system operators will need to adapt their system operation policy to facilitate the efficient and cost effective integration of wind power. This paper illustrate the relative merits of adopting different system operational approaches on a system with significant wind power capacity. The impact on conventional generation, reserve levels and emissions are assessed and the implications are discussed. The illustrations show that an operational approach, which incorporates wind forecast information, while considering an increased need for reserve due to wind power, results in a more efficient integration of the wind capacity.

This paper approximates the emissions rebound effects' associated with substituting expensive and GHG emitting natural gas (LNG) power plants, with apparently cheaper and lower emitting nuclear plant. It then evaluates the effect this has on economy wide electricity use as well as net GHG emissions changes. The analysis is undertaken by combining aspects of an input-output model with an optimizing energy systems model. The scope of the case study is limited to the effects of the electricity sector (and its emissions) on the Korean economy from 2005 to 2030. Its primary basis (in terms of data and assumptions) is the recent national Basic Plan for Long-Term Electricity Supply and Demand (KPX, 2006).(2) The cases...

Wind power is widely expected to expand rapidly in Britain over the next decade. Large amounts of variable wind power on the system will increase market risks, with prices more volatile and load factors for conventional thermal plant lower and more uncertain. This extra market risk may discourage investment in generation capacity. Financial viability for thermal plant will be increasingly dependent on price spikes during periods of low wind. Increased price risk will also make investment in other forms of low-carbon generation (e.g. nuclear power) more challenging. A number of policies can reduce the extent to which generators are exposed to market risks and encourage investment. However, market risks play a fundamental...
A system dynamic model is presented, which considers the feedback between supply and demand and oil revenue of the existing system in Iran considering different sectors of the economy. Also the export of the oil surplus and the injection of the gas surplus into the oil reservoirs are seen in the model by establishing a balance between supply and demand. In this model the counter-effects and existing system feedbacks between supply and demand and oil revenue can be seen considering different sectors of the economy. As a result, the effects of oil and gas policies in different scenarios for different sectors of Iran's economy together with the counter-effects of energy consumption and oil revenue are examined. Three...

In this study, we simulate global CO2 emissions and their reduction potentials in the industrial sector up to the year 2030. Future industrial CO2 emissions depend on changes in both technology and industrial activity. However, earlier bottom-up analyses mainly focused on technology change. In this study, we estimate changes in both technology and industrial activity. We developed a three-part simulation system. The first part is a macro economic model that simulates macro economic indicators, such as GDP and value added by sector. The second part consists of industrial production models that simulate future steel and cement production. The third part is a bottom-up type technology model that estimates future CO2...

As technical efficiency improvement in energy use remains a touchstone measure to curb greenhouse gas (GHG) emissions, there is substantial concern about whether this approach can offset the large and expanding impacts of human actions. Critics contend that without adjustments to the prevailing consumptive lifestyle, energy efficiency improvement will generate only token reductions in GHG emissions. I address this concern by examining the extent to which technical efficiency improvement in energy use offsets the impacts of housing-related lifestyle on GHG emissions. I build from two perspectives, the physical-technical-economic models that consider energy efficiency improvement as a potent strategy to curb residential...

On the question of whether natural resources are a curse for growth, the jury is still out. While waiting for a decision, we study whether resource intensity has any effect on social development over and above the effect it might have on income or growth. We measure social development by a combination of health and education outcomes and resource intensity by the share of primary commodities in total merchandise exports. We find that, after controlling for per-capita income and other macroeconomic and institutional factors, a higher dependence on primary commodity exports is negative for social development. The transmission mechanism seems to operate via income inequality and macroeconomic volatility.
