Time-Variant Pricing in NY’s REV

Author(s): Beia Spiller

Throughout most of the country, residential electricity customers pay the same price for electricity regardless of when it is consumed. Such flat rates mask the fact that true system costs vary over time according to electricity demand. Prices that better reflect the time-varying costs of producing and delivering electricity can lead to a number of economic and environmental gains, such as reduced wholesale prices, increased investment in clean distributed energy resources, and lower overall carbon emissions. Time-variant electricity pricing gives customers greater control over their electricity bills, since they can use electricity when it is cheaper and cut back when… [more]

Full Title: Optimization of Carbon-Capture-Enabled Coal-Gas-Solar Power Generation Author(s): Philip G. Brodrick, Charles A. Kang, Adam R. Brandt, Louis J. Durlofsky Publisher(s): Elsevier Publication Date: Full Text: ->DOWNLOAD DOCUMENT<- Description (excerpt): 12/2014 Computational optimization is used to determine the optimal design and time-varying operations of a carbon dioxide capture retrofit to a coal-fired power plant. The retrofit consists of an amine-based temperature-swing absorption system, to which process steam is supplied from an auxiliary unit. Two candidate auxiliary heat sources are explored: natural gas and solar thermal. The NPV (net present value) of the retrofitted facility is maximized to determine which auxiliary… [more]

Climate Engineering: Solution or Problem?

Author(s): Simon Nicholson
Assistant Professor
American University
Date: March 18, 2015 at 9:00 AM

On February 10, the National Academy of Sciences (NAS) released two major new reports on climate engineering (or “geoengineering”). The reports set out to summarize the scientific basis for what the authors chose to call “climate intervention,” identify governance and ethical challenges, and chart a new research agenda. While the authors were careful to state that climate intervention is no substitute for reduction in carbon dioxide emissions, the reports indicate support for further investigation into large-scale technological responses. The paired studies assess two specific groups of strategies: (1) carbon dioxide removal and (2) reflecting sunlight, or albedo modification. While the… [more]

Full Title: Evolution of the Grid Edge: Pathways to Transformation Author(s): A GTM Research Whitepaper Publisher(s): GTM Research Publication Date: 2015 Full Text: ->DOWNLOAD DOCUMENT<- Description (excerpt): ​​The three GTM Research-identified pathways: ​”​The Advanced Energy Consumer,​”​ ​”​The Innovative Regulator,​”​ and ​”​The Proactive Energy Provider”​ offer some milestones as to when various grid edge technology decisions are likely to be made. Though some of these may appear on the surface to have similar tendencies, it can be used as a framework for solution providers to plan where their offerings could offer the most value to utilities and energy providers undergoing this transformation.

Full Title: Oil Medium-Term Market Report: Market Analysis and Forecasts to 2019 Author(s): International Energy Agency Publisher(s): International Energy Agency Publication Date: 2014 Full Text: ->DOWNLOAD DOCUMENT<- Description (excerpt): While the non-conventional supply revolution that is reshaping the oil market and industry has been widely recognised as a game changer, this transformation is playing out in unexpected ways and against an evolving backdrop. How long will the rise in US tight oil and Canadian oil sands last and where will it leave North American oil production at the end of the decade? Will other countries have managed to replicate the US success… [more]

Full Title: Forecasting the limits to the availability and diversity of global conventional oil supply: Validation Author(s): John L. Hallock Jr., Wei Wu, Charles A.S. Hall, Michael Jefferson Publisher(s): Elsevier, Energy Policy Publication Date: 2014 Full Text: ->DOWNLOAD DOCUMENT<- Description (excerpt): Oil and related products continue to be prime enablers of the maintenance and growth of nearly all of the world’s economies. The dramatic increase in the price of oil through mid-2008, along with the coincident (and possibly resultant) global recession, highlight our continued vulnerability to future limitations in the supply of cheap oil. The very large differences between the various… [more]

Full Title: EROI of different fuels and the implications for society Author(s): Charles A.S. Hall, Jessica G. Lambert, Stephen B. Balogh Publisher(s): Elsevier, Energy Policy Publication Date: 2014 Full Text: ->DOWNLOAD DOCUMENT<- Description (excerpt): All forms of economic production and exchange involve the use of energy directly and in the transformation of materials. Until recently, cheap and seemingly limitless fossil energy has allowed most of society to ignore the importance of contributions to the economic process from the biophysical world as well as the potential limits to growth. This paper centers on assessing the energy costs of modern day society and its relation… [more]

Full Title: Energy, EROI and Quality of Life Author(s): Jessica G. Lambert, Charles A.S. Hall, Stephen Balogh, Ajay Gupta, Michelle Arnold Publisher(s): Elsevier: Energy Policy Publication Date: 2014 Full Text: ->DOWNLOAD DOCUMENT<- Description (excerpt): The near- and long-term societal effects of declining Energy Return on Investment (EROI) are uncertain, but probably adverse. A major obstacle to examining social implications of declining EROI is that we do not have adequate empirical understanding of how EROI is linked, directly or indirectly, to an average citizen′s ability to achieve well- being. To evaluate the possible linkages between societal well-being and net energy availability, we compare… [more]

EPA’s Methane Rule Comes Up Short

Author(s): Dr. Robert Howarth

Date: March 10, 2015 at 9:15 AM

The EPA recently announced new regulations for methane emissions, taking an important first step in reducing the impact of this highly potent greenhouse gas (GHG). But the rule falls short, in part because EPA has systematically underestimated methane emissions from the oil and gas industry. Emissions from conventional natural gas are likely to be at least 2- to 3-fold greater than the EPA estimates, according to several recent studies. Recent literature also suggests emissions from shale gas may be twice as much greater still, based on an observed large increase in methane in the atmosphere over recent years, with the… [more]

What’s the Most Likely Outcome of the Keystone XL Saga?

On February 24th, President Obama vetoed legislation that would have authorized construction of the Keystone XL Pipeline as it “conflicts with established executive branch procedures and cuts short thorough consideration of issues that could bear on our national interest.” It is still possible that President Obama will approve construction of the highly controversial pipeline. In fact, a number of outcomes for the executive review are still possible and a district court judge in York County, Nebraska, just granted local landowners a preliminary injunction against TransCanada’s use of eminent domain for the proposed pipeline in a move that further complicates the… [more]
