The specialized literature indicates that emissions of greenhouse gases, by their nature variable in time and space, are responsible for the emergence and manifestation of the phenomenon of climate change or global warming. It was found that with the increase in air temperature, wind event...

Lack of access to electricity and modern cooking fuels constitutes energy poverty. Access to modern energy requires improved technologies and financing instruments and sources. The pro-poor public-private partnership model is one useful vehicle for raising capital to finance projects. Five...

A tubular cavity-receiver that uses air as the heat transfer fluid is evaluated numerically using a validated heat transfer model. The receiver is designed for use on a large-span (9m net concentrator aperture width) solar parabolic trough concentrator. Through the combination of a parabolic...

The U.S. national electric grid is facing significant changes due to aggressive federal and state targets to decrease emissions while improving grid efficiency and reliability. Additional challenges include supply/demand imbalances, transmission constraints, and aging infrastructure. A...

The present report aims to generate greater awareness and environmental consciousness amongst our citizens. The objective of the report, therefore, is to generate a national debate among various stakeholders on the key environmental issues and challenges that must be addressed to ensure a rapid...

Using the most comprehensive data file ever compiled on air pollution, water pollution, environmental regulations, and infant mortality from a developing country, the paper examines the effectiveness of India’s environmental regulations. The air pollution regulations were effective at...

The Clean Air Act (CAA) and Clean Water Act (CWA) have been the lynchpins of the U.S. environmental policy for the last half century. Under both acts the federal government sets standards and the states implement, the outcomes of the CAA and CWA have not been the same however. While criteria air...

The Energy Policy Act of 2005 authorized the Department of Energy to guarantee loans for new or significantly improved energy production technologies that avoid, reduce, or sequester air pollutants and other greenhouse gases. As of December 2008, Congress authorized the Department to make $42.5...

This report describes an assessment of the co-benefits for air pollution of recently developed climate mitigation scenarios that inform the European Union policy making. The climate mitigation scenarios were obtained with the POLES equilibrium model for a business-as-usual and greenhouse gas...

Representatives of the Federal Aviation Administration (FAA) and several air carriers under Title 14 of the Code of Federal Regulations (CFR) Part 121 developed a system-engineering model of the functions of air-carrier operations. Their analyses form the foundation or basic architecture upon...

An analysis of the economic implication of judicial activism of the apex court of India in the regulation of automotive air pollution is analysed. It estimates the health damage cost of urban air pollution for 35 major urban agglomerations of India arising from automotive emissions and the...

In this study, an approach to modify and improve of CH4(methane)/air pre-mixed flame in a micro-stepped tube combustor is numerically studied. The effects of wire on flame in micro combustor are calculated using a high order, high accuracy 2D steady state code. The results show that the wire...

This report discusses the potential for solar-powered agricultural irrigation pumps in the San Joaquin Valley and how these applications could improve the region's air This paper presents results from the Wind Deployment Systems Model (WinDS) for several potential energy policy cases. WinDS is a...

Over the past two decades the U.S. Environmental Protection Agency (EPA) has issued a series of Federal guidance documents for the purpose of providing the Federal and State agencies with technical information to assist their implementation of radiation protection programs. Currently recommended...

The first phase of the Hualapai Tribal Utility Development Project (Project) studied the feasibility of establishing a tribally operated utility to provide electric service to tribal customers at Grand Canyon West (see objective 1 below). The project was successful in completing the analysis of...

Despite efforts to mandate and finance local governments' provision of environmental sanitation services, outcomes remain poor in the villages surveyed in the four South Indian states. The analysis indicates some key issues that appear to hinder improvements in sanitation. Local politicians tend...

After a short presentation of the URSUS brewery, including the enlargement of the products scale, the paper presents the study and the management of wastes resulted from the technological process and their environmental impact. The studies of the impact on water, air and soil are pointed out....

In this study, an approach to modification and improvement of CH4/air pre-mixed flame in a micro-stepped tube is numerically studied. The effects of added hydrogen to methane as an additive, entrance mixture velocity and some physical properties such as the micro-stepped tube wall thermal...
