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

Physics Faculty Publications

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 …

Logistic Curves, Extraction Costs And The Effective Size Of Oil Resources, Robert J. Brecha

Physics Faculty Publications

The size of potential fossil fuel resources is an issue of perennial interest and controversy. Fundamentally, there appears to be a conflict in interpretation of available data for both past and future extraction histories. As fossil-fuel prices rose dramatically over the past several years, the question of resources once again became acute. In this paper we concentrate on conventional and non-conventional oil resources and make four main points, with the overarching theme that one can determine an effective oil resource that represents significantly less availability for consumption than usually posited by tallying resources in place.

First, looking at oil production …

Best Management Practices (BMPs): What? How? And Why? (May 26)

The Environmentally Friendly Drilling Systems (EFD) Program, managed by the Houston Advanced Research Center, works to identify, develop and transfer critical, cost effective, new technologies that can provide policy makers and industry with the ability to develop natural gas reserves in a safe and environmentally friendly manner. Funding for the EFD Program is through a grant from the Research Partnership to Secure Energy for America, established under the 2005 Energy Act. Within the EFD Program, some projects focus on technologies for developing energy sources in environmentally sensitive areas; others (like the NRLC’s BMP Project) seek ways to reduce the environmental …

The Green, Blue And Grey Water Footprint Of Crops And Derived Crop Products, Mesfin Mekonnen, Arjen Y. Hoekstra

Daugherty Water for Food Global Institute: Faculty Publications

Abstract. This study quantifies the green, blue and grey water footprint of global crop production in a spatially-explicit way for the period 1996–2005. The assessment improves upon earlier research by taking a high-resolution approach, estimating the water footprint of 126 crops at a 5 by 5 arc minute grid. We have used a grid-based dynamic water balance model to calculate crop water use over time, with a time step of one day. The model takes into account the daily soil water balance and climatic conditions for each grid cell. In addition, the water pollution associated with the use of nitrogen …

National Water Footprint Accounts: The Green, Blue And Grey Water Footprint Of Production And Consumption. Volume 1: Main Report, Mesfin Mekonnen, Arjen Y. Hoekstra

Daugherty Water for Food Global Institute: Faculty Publications

This study quantifies and maps the water footprints of nations from both a production and consumption perspective and estimates international virtual water flows and national and global water savings as a result of trade. The entire estimate includes a breakdown of water footprints, virtual water flows and water savings into their green, blue and grey components. The main finding of the study can be summarized as:

The global water footprint in the period 1996-2005 was 9087 Gm3/yr (74% green, 11% blue, 15% grey). Agricultural production contributes 92% to this total footprint.

About one fifth of the global water footprint relates …

Assessing The Stability, Biological Transfer And Developmental Impact Of Environmentally Relevant Nitrosamines Using A Chicken Egg Model, Nikita Joshi

Environmental Health, Occupational Health, and Toxicology: Dissertations and Student Research

Nitrosamines comprise a large group of potentially toxic compounds occurring in the environment as by-products of various manufacturing, agricultural and natural processes. Nitrosamines are produced from reaction of nitrite with a suitable secondary amine in an acidic matrix; these acidic conditions can occur in environmental media and in the mammalian gastrointestinal (GI) tract. This research focused on the stability, transfer, and impacts of the environmentally relevant nitrosamines, N-nitrosodimethylamine (NDMA), N-nitrosmorpholine (NMOR), and N-nitrosoatrazine (NNAT) (formed from reaction of nitrite with dimethylamine, morpholine, and atrazine), using the chicken egg and embryo model systems. Chicken eggs were used to …
