An analysis of extinction coefficients of particles and water moisture in the stack after flue gas desulfurization at a coal-fired power plant
Two important factors that affect in-stack opacity—light extinction by emitted particles and that by water moisture after a flue gas desulfurization (FGD) unit—are investigated. The mass light extinction coefficients for particles and ...

Biodiesel versus diesel: a pilot study comparing exhaust exposures for employees at a rural municipal facility
Many organizations interested in renewable, domestic energy have switched from petroleum diesel to biodiesel blends for use in transportation and heavy-duty equipment. Although considerable evidence exists on the negative health effects of petroleum ...

Wind power status, barriers, and opportunities
In the wake of the oil crisis in the early 1970s, governments around the world were anxious to diversify energy supply away from fossil sources, and so harnessing the wind was seen as an important component of this policy initiative. A decade of ...

EPA`s proposed underground injection control regulations
As the drivers for global climate change become better understood by scientists, politicians, industry, and the public, there is growing consensus that action should be taken to limit atmospheric emissions of carbon dioxide (CO2) and other ...

Biodiesel fuel for transportation: Status and issues in the United States
The United States consumed 3.39 billion barrels of gasoline, 1.54 billion barrels of diesel fuel, and 0.59 billion barrels of jet fuel in 2007. And it currently imports 3.66 billion barrels of oil and petroleum products per year, 65% of US ...

Feasibility of landfill gas as a liquefied natural gas fuel source for refuse trucks
The purpose of this paper is to develop a methodology to evaluate the feasibility of using landfill gas (LFG) as a liquefied natural gas (LNG) fuel source for heavy-duty refuse trucks operating on landfills. Using LFG as a vehicle fuel can make the ...

Diversifying power generation in a carbon-constrained future
The US electricity industry faces operational and environmental challenges of unprecedented scope and complexity. Demand for electric power is increasing even as much of the generation fleet ages and capacity stagnates. Climate research and policy ...

Key Questions for Analysts of Energy Balances and Other Policy Analyses
Untitled Document The United States imports approximately one third of its energy sources, mostly in the form of petroleum. 1 Heightened interest in finding alternative fuels, and thus reducing the U.S. reliance on ...

Methylmercury, Fish Consumption, and the Precautionary Principle
This paper considers several broad issues in the context of probabilistic assessment of the benefits of curtailing mercury (Hg) emissions from U.S. coal fired power plants, based on information developed from recent literature and epidemiology ...

A Pilot Study of Mercury Liberation and Capture from Coal-Fired Power Plant Fly Ash
The coal-fired electric utility generation industry has been identified as the largest anthropogenic source of mercury (Hg) emissions in the United States. One of the promising techniques for Hg removal from flue gas is activated carbon ...

When vapors intrude...
Vapor intrusion (VI) is the migration of gas-phase chemicals from the subsurface into buildings or other structures. It is one of the exposure pathways that should be considered when performing a site human health risk assessment and can be an ...

An Introduction to the Topic: Controlling Mercury Emissions from Coal-Fired Power Plants
Untitled Document Mercury is a hazardous air pollutant (HAP) that circulates around the globe for a year before depositing back to earth. Mercury emissions from electric power generation sources were estimated by the ...
