Emissions Scenarios In The Face Of Fossil-Fuel Peaking, Robert Brecha Feb 2016

Emissions Scenarios In The Face Of Fossil-Fuel Peaking, Robert Brecha

Robert J. Brecha

Emissions scenarios used by the Intergovernmental Panel on Climate Change (IPCC) are based on detailed energy system models in which demographics, technology and economics are used to generate projections of future world energy consumption, and therefore, of greenhouse gas emissions. We propose in this paper that it is useful to look at a qualitative model of the energy system, backed by data from short- and medium-term trends, to gain a sense of carbon emission bounds. Here we look at what may be considered a lower bound for 21st century emissions given two assumptions: first, that extractable fossil-fuel resources follow the …


The Carbon Rent Economics Of Climate Policy, Matthias Kalkuhl, Robert Brecha Jan 2016

The Carbon Rent Economics Of Climate Policy, Matthias Kalkuhl, Robert Brecha

Robert J. Brecha

By reducing the demand for fossil fuels, climate policy can reduce scarcity rents for fossil resource owners. As mitigation policies ultimately aim to limit emissions, a new scarcity for “space” in the atmosphere to deposit emissions is created. The associated scarcity rent, or climate rent (that is, for example, directly visible in permit prices under an emission trading scheme) can be higher or lower than the original fossil resource rent. In this paper, we analyze analytically and numerically the impact of mitigation targets, resource availability, backstop costs, discount rates and demand parameters on fossil resource rents and the climate rent. …


Logistic Curves, Extraction Costs And Peak Oil, Robert Brecha Jan 2016

Logistic Curves, Extraction Costs And Peak Oil, Robert Brecha

Robert J. Brecha

Debates about the possibility of a near-term maximum in world oil production have become increasingly prominent over the past decade, with the focus often being on the quantification of geologically available and technologically recoverable amounts of oil in the ground. Economically, the important parameter is not a physical limit to resources in the ground, but whether market price signals and costs of extraction will indicate the efficiency of extracting conventional or nonconventional resources as opposed to making substitutions over time for other fuels and technologies. We present a hybrid approach to the peak-oil question with two models in which the …


Economic And Environmental Impacts Of Community-Based Residential Building Energy Efficiency Investment, Jun-Ki Choi, Drew Morrison, Kevin Hallinan, Robert Brecha Jan 2016

Economic And Environmental Impacts Of Community-Based Residential Building Energy Efficiency Investment, Jun-Ki Choi, Drew Morrison, Kevin Hallinan, Robert Brecha

Robert J. Brecha

A systematic framework for evaluating the local economic and environmental impacts of investment in building energy efficiency is developed. Historical residential building energy data, community-wide economic input-output data, and emission intensity data are utilized. The aim of this study is to show the comprehensive insights and connection among achieving variable target reductions for a residential building energy use, economic and environmental impacts. Central to this approach for the building energy reduction goal is the creation of individual energy models for each building based upon historical energy data and available building data. From these models, savings estimates and cost implications can …


Development Without Energy? Assessing Future Scenarios Of Energy Consumption In Developing Countries, Jan Steckel, Robert Brecha, Michael Jakob, Jessica Strefler, Gunnar Luderer Jan 2016

Development Without Energy? Assessing Future Scenarios Of Energy Consumption In Developing Countries, Jan Steckel, Robert Brecha, Michael Jakob, Jessica Strefler, Gunnar Luderer

Robert J. Brecha

We analyze the relationship between economic development and energy consumption in the context of greenhouse gas mitigation. The main contribution of this work is to compare estimates of energy thresholds in the form of minimum energy requirements to reach high levels of development with output projections of per capita final energy supply from a group of integrated assessment models (IAMs). Scenarios project that reductions of carbon emissions in developing countries will be achieved not only by means of decreasing the carbon intensity, but also by making a significant break with the historically observed relationship between energy use and economic growth. …

Variable Renewable Energy In Modeling Climate Change Mitigation Scenarios, Falko Ueckerdt, Robert J. Brecha, Gunnar Luderer, Patrick Sullivan, Eva Schmid, Nico Bauer, Diana Böttger Jun 2015

Variable Renewable Energy In Modeling Climate Change Mitigation Scenarios, Falko Ueckerdt, Robert J. Brecha, Gunnar Luderer, Patrick Sullivan, Eva Schmid, Nico Bauer, Diana Böttger

Robert J. Brecha

This paper addresses the issue of how to account for short‐term temporal variability of renewable energy sources and power demand in long‐term climate change mitigation scenarios in energy‐economic models. An approach that captures in a stylized way the major challenges to the integration of variable renewable energy sources into power systems has been developed. As a first application this approach has been introduced to REMIND‐D, a hybrid energy‐economy model of Germany. An approximation of the residual load duration curve is implemented. The approximating function endogenously changes depending on the penetration and mix of variable renewable power. The approach can thus …

Robert J. Brecha

An energy reduction program for commercial buildings is implemented for a SW Ohio natural gas utility. The aim of this study is to demonstrate that historical utility data for individual building customers, along with knowledge of pertinent building information (square footage, year built, number of floors, height of floors, wall construction type, and use type) available in county auditor databases, could be used to identify the best candidate buildings for recommissioning in terms of energy savings and simple payback. A study is completed for all natural gas customers of a utility in Montgomery and Clinton counties in Ohio. A total …

EXECUTIVE SUMMARY Exploring energy demand and supply uncertainty: An exploration of uncertainty on drivers of energy demand and supply is indispensable for better understanding the prospects of long-tern climate stabilization. The RoSE study is the first of its kind to systematically explore the impact of economic growth, population and fossil fuel scarcity, in scenarios with and without climate policy, using a model ensemble. A feature of RoSE is the participation of five established integrated assessment modelling teams from three important regions in international climate policy negotiations: the EU, the USA and China. Economic growth: Neither slow nor rapid economic growth …


Economics Of Nuclear Power And Climate Change Mitigation Policies, Nico Bauer, Robert Brecha, Gunnar Luderer Jun 2015

Economics Of Nuclear Power And Climate Change Mitigation Policies, Nico Bauer, Robert Brecha, Gunnar Luderer

Robert J. Brecha

The events of March 2011 at the nuclear power complex in Fukushima, Japan, raised questions about the safe operation of nuclear power plants, with early retirement of existing nuclear power plants being debated in the policy arena and considered by regulators. Also, the future of building new nuclear power plants is highly uncertain. Should nuclear power policies become more restrictive, one potential option for climate change mitigation will be less available. However, a systematic analysis of nuclear power policies, including early retirement, has been missing in the climate change mitigation literature. We apply an energy economy model framework to derive …

Historically, economic development has been strongly correlated with increasing energy use and growth of greenhouse gas (GHG) emissions. Renewable energy (RE) can help decouple that correlation, contributing to sustainable development (SD). In addition, RE offers the opportunity to improve access to modern energy services for the poorest members of society, which is crucial for the achievement of any single of the eight Millennium Development Goals. Theoretical concepts of SD can provide useful frameworks to assess the interactions between SD and RE. SD addresses concerns about relationships between human society and nature. Traditionally, SD has been framed in the three-pillar model—Economy, …


Ten Reasons To Take Peak Oil Seriously, Robert Brecha Jun 2015

Ten Reasons To Take Peak Oil Seriously, Robert Brecha

Robert J. Brecha

Forty years ago, the results of modeling, as presented in The Limits to Growth, reinvigorated a discussion about exponentially growing consumption of natural resources, ranging from metals to fossil fuels to atmospheric capacity, and how such consumption could not continue far into the future. Fifteen years earlier, M. King Hubbert had made the projection that petroleum production in the continental United States would likely reach a maximum around 1970, followed by a world production maximum a few decades later. The debate about “peak oil," as it has come to be called, is accompanied by some of the same vociferous denials, …


The Gold Coast Transformed : From Wilderness To Urban Ecosystem, Tor Hundloe, Bridgette Mcdougall, Craig Page Apr 2015

The Gold Coast Transformed : From Wilderness To Urban Ecosystem, Tor Hundloe, Bridgette Mcdougall, Craig Page

Tor Hundloe

Extract: This is the story of a unique city, Australia’s premier tourist city, a city cut out of coastal vegetation, including paperbark swamps, mangroves and rainforests of worldwide significance. The city has a relatively short history as until half a century ago (two human generations) it was but several relatively small villages, each with its own natural and social features. Two generations is a very short time for a city to grow to be the sixth-largest in population in Australia and to have global recognition as the country’s beach playground. The Gold Coast ranks with Honolulu in Hawaii, with Palm …


Feral Deer In The Suburbs: An Emerging Issue For Australia?, Shelley Burgin, Mariama Mattila, Daryl Mcphee, Tor Hundloe Jan 2015

Feral Deer In The Suburbs: An Emerging Issue For Australia?, Shelley Burgin, Mariama Mattila, Daryl Mcphee, Tor Hundloe

Tor Hundloe

Deer are not endemic to Australia, but were introduced for game and aesthetics between the early 18th and 20th centuries. Until recent decades, most deer descended from these introductions. Before the 1970s when deer numbers and distribution expanded dramatically, farming was a modest enterprise. With the collapse of farming in the 1990s, large numbers of deer were deliberately released and translocated. Feral numbers and herds have subsequently expanded, and are increasingly encroaching on urban areas. As a new issue in Australia, views toward feral deer are polarized and span “welcome guest” to “major pest.” The emerging urban deer issues need …

Towards Measuring Interventions In Rainfed Areas, Hippu Salk Kristle Nathan, Rajendra, Srijit Mishra Jan 2015

Towards Measuring Interventions In Rainfed Areas, Hippu Salk Kristle Nathan, Rajendra, Srijit Mishra

Srijit Mishra

This paper underlines the process through which we have arrived at the indicators for various thematic nodes to measure and evaluate interventions or comprehensive pilots in rainfed areas. We conceptualize a simple four stage process, i.e., ‘objective or goal formulation’, 'means finding', 'targets settings' and 'indicator identification', which we refer to as OMTI (Objective-Means-Target-Indicators) framework. In indicator literature, this kind of framework can be categorized under "thematic framework" or "goal oriented framework". The operationalization of OMTI framework highlights its nuances and brings forth its limitations. In order to overcome some of these limitations, we validate the OMTI framework using the …

Designing Carbon Taxation Schemes For Automobiles: A Simulation Exercise For Germany, Adamos Adamou, Sofronis Clerides, Theodoros Zachariadis Dec 2011

Designing Carbon Taxation Schemes For Automobiles: A Simulation Exercise For Germany, Adamos Adamou, Sofronis Clerides, Theodoros Zachariadis

Theodoros Zachariadis

Vehicle taxation based on CO2 emissions is increasingly being adopted worldwide in order to shift consumer purchases to low-carbon cars, yet little is known about the effectiveness and overall economic impact of these schemes. We focus on feebate schemes, which impose a fee on high-carbon vehicles and give a rebate to purchasers of low-carbon automobiles. We estimate a discrete choice model of demand for automobiles in Germany and simulate the impact of alternative feebate schemes on emissions, consumer welfare, public revenues and firm profits. The analysis shows that a well-designed scheme can lead to emission reductions without reducing overall welfare.
