The application of post-combustion capture (PCC) processes in coal fired power stations can result in large reductions of the CO2-emissions, but the consequential decrease in generation efficiency is an important draw-back The leading PCC technology is based on chemical absorption processes as this technology is the one whose scale-up status is closest to full-scale capture in power plants The energy performance of this process is analysed in this contribution. The analysis shows that the potential for improvement of the energy performance is quite large It is demonstrated that further development of the capture technology and the power plant technology can lead to generation efficiencies for power plants with 90%...
After harvesting energy from the wind for centuries, for a long period in history which started with the industrial revolution, wind power development has lagged behind due to the advent of other types of technologies based on fossil fuels and nuclear fission. It was not until the 20th century that technological developments in other fields revolutionized wind power conversion and ultimately led to modern wind turbine systems. This re-emergence of wind as a significant energy source is now encouraged by the need to meet increasing worldwide electricity demand and reduce the environmental impact caused by the conventional electricity generation technologies. Considerable progress in wind-power technology during the...
This paper uses the Jobs and Economic Development Impacts (JEDI) model to estimate economic impacts from 1398 MW of wind power development in four counties in west Texas. Project-specific impacts are estimated at the local level (i.e., within a 100-mile radius around the wind farms) and at the state level. The primary economic policy question addressed is how investment in wind energy affects the state and local communities where the wind farms are built. During the four-year construction phase approximately 4100 FTE (full time equivalents) jobs were supported with turbine and supply chain impacts accounting for 58% of all jobs generated. Total lifetime economic activity to the state from the projects equated to...

Wind power forecasting is becoming an important tool in electricity markets as the amount of wind power rapidly increases. However, the use of wind power forecasting in market operations and among market participants is still at an early stage. We discuss the current use of wind power forecasting in U.S. ISO/RTO markets, and give recommendations for how to make efficient use of the information in state-of-the-art wind power forecasts.
Policymakers and managers in the U.S. energy sector will face complex multidimensional challenges as they confront potential supply shortfalls, infrastructure constraints, and environmental limitations in the years ahead. Using a technique known as scenario analysis, this paper investigates key energy issues and decisions that could improve or reduce the ability of the United States to deal with the uncertainties that may challenge the U.S. economy during the next fifty years. Four scenarios have been developed representing a diverse range of future worlds to explore the driving forces and critical uncertainties that may shape U.S. energy markets and the economy for the next fifty years. Each scenario has been quantified...

The Wyoming wind turbine data set was developed for the project "Seasonal predictive habitat models for Greater Sage-grouse in Wyoming". This project is aimed at developing spatially-explicit seasonal distribution models for Sage-Grouse in Wyoming, which will provide resource managers tools for conservation planning. These specific data are being used for assessing the impact of disturbance resulting from wind energy development within Wyoming on sage-grouse populations. Additionally, this data will also support the Wyoming Landscape Conservation Initiative (WLCI). WLCI is a long-term, science-based, collaborative effort to ensure that the Southwest Wyoming's wildlife and its habitats are sustained over time with...

To determine if invasive annual grasses increased around energy developments after the construction phase, we calculated an invasives index using Landsat TM and ETM+ imagery for a 34-year time period (1985-2018) and assessed trends for 1,755 wind turbines (from the U.S. Wind Turbine Database) installed between 1988 and 2013 in the southern California desert. The index uses the maximum normalized difference vegetation index (NDVI) for early season greenness (January-June), and mean NDVI (July-October) for the later dry season. We estimated the relative cover of invasive annuals each year at turbine locations and control sites and tested for changes before and after each turbine was installed. These data were used...

This essay develops a way lo think about the aesthetics of wind eneriiy .sy.stems. The inqiiiiy be^iins by consideriti^ an increasini(ly familiar dash between aesthetic responses to wind farms: liie NIMBY appreciator of wind farms who likes their ecological ratiotudity but not their look, and the aesthetic appreciator who sees the wind farm as beautiful in part because of its ecological rationality. 1 raise the following questions: Is one ofihe.se perceptions more objeciive than the other? Is one of the aesthetic judgments uttered more truthful than the other? Or is ihis simply a question of subjective or inlermbjeclive preferences? The essay goes on to explore dialeclically the various ways we can think about the...

Through the North American Bat Monitoring Program, United States Geological Survey (USGS) provided technical and science support to assist in U.S. Fish and Wildlife Services’ Species Status Assessment (“SSA”) for the northern long-eared bat (Myotis septentrionalis), little brown bat (Myotis lucifugus), and tri-colored bat (Perimyotis subflavus). USGS facilitated the SSA data call, provided data archival for repeatable and transparent analyses, provided statistical support to assess the historical, current, and future population status for each of the three species, and developed a demographic projection tool to evaluate future viability of each species under multiple threat scenarios. These data represent the derived...

Knowledge of where energy resources occur and where there is existing development or new development potential, in conjunction with model-predicted golden eagle relative nest site density (Dunk et al. 2019), can be used to identify areas with higher or lower potential resource conflict. Depicted on the map is a 16-class raster that displays the spatial overlap of wind resources (4 classes, low to high) and golden eagle relative nest site density (4 classes, lower to higher). This raster displays the intersection of multi-year mean capacity factors (MCF) for wind turbines and the golden eagle relative nest site density within ecoregion raster. We have divided each probability into equal intervals, and then intersected...
The article discusses a report published by the U.S. Dept. of Energy (DOE) that examined the technical feasibility of using wind energy for electricity generation. The report assessed the costs, impacts and challenges associated with the production of 20% wind energy by 2030. Results have shown that there is a need for an enhanced transmission infrastructure and an increase in turbine installations to achieve 20% wind energy.
The 165-km2 Altamont Pass Wind Resource Area (APWRA) in west-central California includes 5,400 wind turbines, each rated to generate between 40 kW and 400 kW of electric power, or 580 MW total. Many birds residing or passing through the area are killed by collisions with these wind turbines. We searched for bird carcasses within 50 m of 4,074 wind turbines for periods ranging from 6 months to 4.5 years. Using mortality estimates adjusted for searcher detection and scavenger removal rates, we estimated the annual wind turbine–caused bird fatalities to number 67 (80% CI = 25–109) golden eagles (Aquila chrysaetos), 188 (80% CI = 116–259) red-tailed hawks (Buteo jamaicensis), 348 (80% CI = −49 to 749) American kestrels...

Wind energy represents an important alternative to oil and gas extraction to meet increasing energy demands, but it has the potential to disrupt wildlife populations. Because behavioral adjustments, such as altered habitat selection, are a primary way that long-lived species respond to novel disturbances, USGS scientists evaluated effects of wind energy development on pronghorn (Antilocapra americana) space use and habitat selection. Using data from GPS-collared female pronghorn in the Shirley Basin of south-central Wyoming, USA, we tested four potential effects of wind turbines on pronghorn space use during the summer and winter: 1) displacement away from wind turbines, 2) increase in size of home ranges, 3) short-term...
