Network Constrained Wind Integration: An Optimal Cost Approach 31
Maddaloni, Jesse D.; Rowe, Andrew M.; van Kooten, G. Cornelis.
Planning electricity supply is important because power demand continues to increase while there is a concomitant desire to increase reliance on renewable sources. Extant research pays particular attention to highly variable, low-carbon energy sources such as wind and small-scale hydroelectric power. Models generally employ only a simple load levelling technique, ensuring that generation meets demand in every period. The current research considers the power transmission system as well as load levelling. A network model is developed to simulate the integration of highly variable non-dispatchable power into an electrical grid that relies on traditional generation sources, while remaining within the network’s operating constraints. The model minimizes a...

The Induced Innovation Hypothesis and Energy-Saving Technological Change 31
Newell, Richard G.; Jaffe, Adam B.; Stavins, Robert N..
We develop a methodology for testing Hick's induced innovation hypothesis by estimating a product-characteristics model of energy-using consumer durables, augmenting the hypothesis to allow for the influence of government regulations. For the products we explored, the evidence suggests: (i) the rate of overall innovation was independent of energy prices and regulations, (ii) the direction of innovation was responsive to energy price changes for some products but not for others, (iii) energy price changes induced changes in the subset of technically feasible models that were offered for sale, (iv) this responsiveness increased substantially during the period after energy-efficiency product labeling was required, and (v) nonetheless, a sizeable portion of...

Strategic Resource Dependence 31
Gerlagh, Reyer; Liski, Matti.
We consider a situation where an exhaustible-resource seller faces demand from a buyer who has a perfect substitute but there is a time-to-build delay for the substitute. We that find in this simple framework the basic implications of the Hotelling model (1931) are reversed: over time the stock declines but supplies increase up to the point where the buyer decides to switch. Under such a threat of demand change, the supply does not reflect the true current resource scarcity but leads to increased future scarcity, felt during the transition to the substitute supplies. The analysis suggests a perspective on costs of oil dependence.

The Economics of Wind Power with Energy Storage 31
Benitez, Pablo C.; Dragulescu, Lilianna; van Kooten, G. Cornelis.
We develop a nonlinear mathematical optimization program for investigating the economic and environmental implications of wind penetration in electrical grids and evaluating how hydropower storage could be used to offset wind power intermittence. When wind power is added to an electrical grid consisting of thermal and hydropower plants, it increases system variability and results in a need for additional peak-load, gas-fired generators. Our empirical application using load data for Alberta’s electrical grid shows that 32% wind penetration (normalized to peak demand) results in a net cost increase of $C5.20/ MWh, while 64% wind penetration could result in an increase of $12.50/MWh. Costs of reducing CO2 emissions are estimated to be $41-$56 per t CO2 . When...

Economic Effects of Biofuel Production on States and Rural Communities 31
Parcell, Joseph L.; Westhoff, Patrick C..
This study summarizes research on farm-, local-, regional-, and macro-level economic effects of ethanol production. Given current production levels, the ethanol production industry annually employees approximately 3,500 workers, pays out nearly $132 million in worker salaries, generates over $110 million in local taxes, and takes in some $2 billion in government incentive payments. Projections for a 60 million gallon per year ethanol plant indicate an annual increase in corn usage of 21 million bushels, a one-time capitalization of $75 million, an increase in local corn prices between $0.06/bushel and $0.12/bushel, a 54 direct and 210 indirect jobs created, and increase in local tax revenues of $1.2 million, a decrease in federal commodity program...

The Linkages between Energy Efficiency and Security of Energy Supply in Europe 31
Bigano, Andrea; Arigoni Ortiz, Ramon; Markandya, Anil; Menichetti, Emanuela; Pierfederici, Roberta.
It can be argued that one way to reduce the dependence from external energy sources, is simply to reduce the demand for energy. Energy savings may thus be considered a policy priority when concerns for energy security are particularly strong. Drawing on an original econometric approach, we check whether policies and measures that affect indicators of energy efficiency performance have an analogous effect on security of supply indicators, both at the whole economy level and within the main sectors of energy use in the EU 15 countries and Norway. Our analyses show that the indicators studied are affected by a number of policies and measures; however very few of them seem able to tackle effectively and simultaneously, energy efficiency, carbon efficiency and...

Factors Affecting Direct and Indirect Energy Use in U.S. Corn Production 31
Musser, Wesley N.; Lambert, Dayton M.; Daberkow, Stan G..
The recent volatility of energy prices has numerous policy implications for agriculture. A better understanding of the factors associated with energy consumption as related to crop production management decisions and technology use may provide insight about how producers might respond to program or market incentives targeting energy use in particular, and soil and water conservation in general. Adoption of minimum tillage could reduce erosion and improved fertilizer management practices could reduce nitrogen runoff. Energy costs may be reduced with adoption of reduced tillage technology, improved drying and irrigation systems, or more careful attention to the application and timing of fertilizers.

Social and Ethical Considerations of Nuclear Power Development 31
Parkins, John R.; Haluza-DeLay, Randolph.
A new urgency is emerging around nuclear power development and this urgency is accentuated by the post-tsunami events at the Fukushima Daiichi nuclear power plant in Japan. This urgency extends beyond these dramatic events in Japan, however, to many other regions of the world and situations where nuclear power development is receiving renewed attention as an alternative to carbon-based energy sources. As a contribution to the growing public debate about nuclear power development, this paper offers a set of insights into the social and ethical aspects of nuclear power development by drawing from published literature in the humanities and social sciences. We offer insights into public risk perception of nuclear power at individual and national levels, the...

Economics of Natural Resource Scarcity: The State of the Debate 31
Krautkraemer, Jeffrey A..
Whether economic growth can be sustained in a finite natural world is one of the earliest and most enduring questions in economic literature. Even with unprecedented growth in human population and resource consumption, humans have been quite adept at finding solutions to the problem of scarce natural resources, particularly in response to signals of increased scarcity. Because environmental resources generally are not generally traded on markets, however, scarcity signals for these resources may be inadequate, and appropriate policy responses are difficult to implement and manage. In the debate over the economic scarcity of natural resources, one significant change in recent years has been a greater focus on the ecosystem services and the resource...

Effects of Carbon Policies and Technology Change 31
MacAuley, Molly K.; Shih, Jhih-Shyang.
We develop and estimate an index-based measure of expected consumer welfare under various carbon emissions control policies in the electricity generation sector. This approach estimates welfare effects by a somewhat less data intensive methodology than econometric approaches or more complex modeling. We include anticipated technological change in the production of renewable and nonrenewable power generation during the next two decades. We estimate welfare improvements from 2000 to 2020 as renewable energy technologies continue to be improved and gradually adopted, compared with a counterfactual scenario allowing for continual improvement of nonrenewable generation technology. We formally incorporate uncertainty. We evaluate the model under alternative...

The Potential for Wind Energy Meeting Electricity Needs on Vancouver Island 31
Prescott, Ryan; van Kooten, G. Cornelis; Zhu, Hui.
In this paper, an in-depth analysis of power supply and demand on Vancouver Island is used to provide information about the optimal allocation of power across ‘generating’ sources and to investigate the economics of wind generation and penetrability into the Island grid. The methodology developed can be extended to a region much larger than Vancouver Island. Results from the model indicate that Vancouver Island could experience blackouts in the near future unless greater name-plate capacity is developed. While wind-generated energy has the ability to contribute to the Island’s power needs, the problem with wind power is its intermittency. The results indicate that wind power may not be able to prevent shortfalls, regardless of the overall name-plate...

Carbon Dioxide Capture and Storage (CCS) - Liability for Non-Permanence under the UNFCCC 31
Bode, Sven; Jung, Martina.
Prior to CoP 10, our discussion paper "On the Integration of Carbon Capture and Storage into the International Climate Regime" argued that carbon capture and storage (CCS) was similar to carbon sequestration in the area of Land Use, Land-Use Change and Forestry (LULUCF). This was criticized by several readers who observed that treating CCS as a removal activity (sink) would not be compatible with the UNFCCC sink definition, what we already had mentioned in the paper. The present paper is based on the UNFCCC definition and analyses how CCS could be integrated into the climate regime. As CO2 may re-enter the atmosphere after injection into geological reservoirs, the question of long-term liability has to be considered. Apart from this aspect, additional...

Interfuel Substitution: A Meta-Analysis 31
Stern, David I..
Interfuel substitutability has been of longstanding interest to energy economists and policy makers. However, there has been no quantitative meta-analysis of this literature. This research report fills this gap by analysing a broad sample of studies of interfuel substitution in the industrial sector, manufacturing industry or sub-industries, and macro-economy of a variety of developed and developing economies. The primary study sample size has been included in the meta-regression to control for publication bias. At the industrial level, results for the shadow elasticities of substitution between coal, oil, gas, and electricity for forty-six primary studies show that, except for gas-electricity and coal-electricity, there are easy substitution...

Technological Change, Fuel Efficiency and Carbon Intensity in Electricity Generation: A Cross-Country Empirical Study 31
Verdolini, Elena; Johnstone, Nick; Hascic, Ivan.
This paper provides an empirical analysis of the determinants of energy efficiency in fossil fuel electricity generation across 28 OECD countries over the period 1981-2006, with particular attention to the role played by technological development and the availability of energy efficient technologies in the market. This contribution is novel in three respects: first, empirically assess the effects of different determinants of energy efficiency, which include the input mix in electricity generation, the capacity ratio at which power plants are run, as well as the characteristics of the production technology. Second, we focus on the role of technological availability: using patent data for carefully selected innovations in fossil-fuel technologies, we build...

On the Evolving Relationship between Corn and Oil Prices 31
Elmarzougui, Eskandar; Larue, Bruno.
The relationship between corn and oil prices is not a stable one. We identified three breaks in the relationship between corn and oil prices. The first break coincides with the second oil crisis. The second break marks the end of the agricultural export subsidy war between the EU and the US in the mid 1980s while the third one occurred at the beginning of the ethanol boom at the very end of the 1990s. The relationship between corn and oil prices tends to be stronger when oil prices are highly volatile and when agricultural policies create less distortion. The ethanol boom strengthened the relation between corn and oil prices which are (were not) cointegrated in the fourth regime (first three) regime(s). Impulse response functions confirm that corn prices...

CO2-Abscheidung und Ablagerung (CAA): Ordnungsrechtliche Aspekte und okonomische Implikationen im Rahmen des EU - Emissionshandels 31
Dietrich, Lars; Bode, Sven.
Die Abscheidung von Kohlendioxid in großen, immobilen Industrieanlagen mit anschließender Ablagerung in geologischen Formationen gewinnt in jüngster Zeit in der Diskussion um Maßnahmen zur Reduktion von Treibhausgasen zunehmend an Bedeutung. Der Bau von Pilotanlagen ist inzwischen auch für Deutschland angekündigt worden. Diese neue Technik birgt dabei grundsätzlich die Gefahr von Wiederaustritten des abgeschiedenen und verpressten CO2 in die Atmosphäre. Vor diesem Hintergrund untersucht das vorliegende Papier ausgewählte ordnungsrechtliche Aspekte sowie ökonomische Implikationen im Rahmen des EU-Emissionshandels. Die Analyse zeigt, dass derartige Anlagen mit einer Ausnahme zur Zeit keinem dem Gefahrenpotential entsprechenden Genehmigungsverfahren...

Utility-scale Wind Power: Impacts of Increased Penetration 31
Pitt, Lawrence; van Kooten, G. Cornelis; Love, Murray; Djilali, Ned.
Intermittent renewable energy sources such as wind, solar, run-of-river hydro, tidal streams and wave fluxes present interesting challenges when exploited in the production of electricity, which is then integrated into existing and future grids. We focus on wind energy systems because they have an emerging presence, with new installed capacity approaching 8 GW annually. We survey many studies and compile estimates of regulation, load following and unit commitment impacts on utility generating assets with increasing wind penetration. Reliability (system reserve), observed capacity factors and the effective capacity (ability to displace existing generation assets) of wind energy systems are discussed. A simple energy balance model and some results from...

A Robust Multivariate Long Run Analysis of European Electricity Prices 31
Bosco, Bruno; Parisio, Lucia; Pelagatti, Matteo; Baldi, Fabio.
This paper analyses the interdependencies existing in wholesale European electricity prices. The results of a multivariate long run dynamic analysis of weekly median prices reveal the presence of a strong although not perfect integration among some neighboring markets considered in the sample and the existence of common long-term dynamics of electricity prices and gas prices but not oil prices. The existence of long-term dynamics among gas prices and electricity prices may prove to be important for long-term hedging operations to be conducted even in markets where there are no electricity derivatives.
