Biogas and bio-methane that are based on energy crops are renewable energy carriers and therefore potentially contribute to climate protection. However, significant greenhouse gas (GHG) emissions resulting from agricultural production processes must be considered. Among those, the production and use of fertilizer, and the resulting leaching of nitrous oxide (N2O), are crucial factors. This article provides an integrated life cycle assessment (LCA) of biogas (i.e. bio-methane that has been upgraded and injected into the natural gas grid), taking into account the processes of fermentation, upgrading and injection to the grid for two different types of biogas plants. The analysis is based on different feedstocks from...
Whenever a neighborhood or community group objects to a proposed development in their area, someone questions whether the objections are part of a NIMBY , or "Not in My Backyard" pattern of responses. According to past studies, one characteristic of a typical NIMBY syndrome is a lack of trust in project sponsors or experts. Most researchers argue that distrust leads to the NIMBY syndrome. Margolis (1996), however, argues that opposition to a proposed development may cause distrust. In this article, we investigate opposition to offshore oil development in California using focusing groups of local political activists on both sides of the issue. Previous research has largely ignored project supporters when studying...
The Southern Appalachian forest region of the U.S.-a region responsible for 23% of U.S. coal production-has 24 billion metric tons of high quality coal remaining of which mountaintop coal mining (MCM) will be the primary extraction method. Here we consider greenhouse gas emissions associated with MCM terrestrial disturbance in the life-cycle of coal energy production. We estimate disturbed forest carbon, including terrestrial soil and nonsoil carbon using published U.S. Environmental Protection Agency data of the forest floor removed and U.S. Department of Agriculture - Forest Service inventory data. We estimate the amount of previously buried geogenic organic carbon brought to the soil surface during MCM using...
SILMU, which runs from 1990 to 1995, aims at studying climate change and its impacts. It also seeks to provide information to Finnish policy makers on adaptation and mitigation. The topics range from air chemisrty to sociology, and the total number of projects is 74. Interim evaluation of the programme was carded out in 1992. During the second half of SILMU, 10 % of the total budget (total: 14 Million ECU) has been devoted to programme integration.
Coalbed methane development has proliferated across much of the western United States. Campbell County, Wyoming, in the Powder River Basin is one area that has seem some of the highest amounts of this development, most of it occurring on land where the surface use is livestock grazing, resulting in conflicts over resource use. This thesis takes a grounded theory approach to understanding the meaning that the ranchers that operate on this land have attached to this development. In doing so, this paper argues that these ranchers form opinions and attitudes based on how CBM has affected “the ranching way of life” and not simply on the perceived opportunity for economic gain. It also argues that although objections...
This article addresses the important but overlooked socio-cultural dimension of sustainability indicators. We use cultural theory to assess indicators of human-environment interaction in different cultural contexts in a case study of a mining-industrial complex in the Kola Peninsula, North-West Russia. The analysis yields results with implications on two levels. First, the article contributes to indicator theory by illustrating with the use of cultural theory how the choice of indicators on one hand and their value range on the other shape and are shaped by culture. Second, with its analysis of the long-term use of environmental indicators, the article contributes to the development of trans-national environmental...
Rising world prices, the growing demand for energy, and the need to mitigate the greenhouse effect are the driving force behind the renewed interest in the use of biofuels. Among the biofuels, biodiesel is one of the best available resources for diesel fuels in diesel engines. Chemically biodiesel is mono alkyl esters of long chain fatty acids derived from renewable feed stock. This article provides in depth and systematic data (reviews from 1944-2010) on technical aspects of biodiesel which will be useful for research and commercial utilization of such promising fuel in a global scenario. This article focused on identification of biodiesel sources, production processes including, pyrolysis, dilution, microemulsion,...

A combination of remote sensing and ecosystem modeling is used to examine the trends in NEP and net ecosystem carbon balance (NECB) in this region over the 1985 - 2007 period, with particular attention to land ownership since management now differs widely between public and private forestland. In the late 1980s, forestland in both ownership classes was subject to high rates of harvesting, and consequently the land was a carbon source (i.e. had a negative NECB). After the policy driven reduction in the harvest level, public forestland became a large carbon sink driven in part by increasing NEP whereas private forestland was close to carbon neutral.
By replacing fossil fuels bioenergy has the potential to reduce greenhouse gas (GHG) emissions, but indirect effects might partly or even completely eliminate this benefit. Production of bio-energy products, such as biofuels for transport, causes several indirect effects through their interactions with the global economic and physical systems. Indirect land-use change leads to GHG emissions – in some cases in the same order of magnitude as the fossil emissions – and loss of nature, but there are other relevant indirect effects as well. Intensification of agricultural production is another indirect effect and could be stimulated more to minimise the undesirable land conversion. However, intensification through increased...

Noise exposure is known to cause hearing loss and a variety of disturbances, such as annoyance, hypertension and loss of sleep. It is generally accepted that these situations are caused by the acoustical events processed by the auditory system. However, there are acoustical events that are not necessarily processed by the auditory system, but that nevertheless cause harm. Infrasound and low frequency noise (ILFN, <500Hz) are acoustical phenomena that can impact the human body causing irreversible organic damage to the organism, but that do not cause classical hearing impairment. Acoustical environments are normally composed of all types of acoustical events: those that are processed by the auditory system, and those...

The southwest states of Arizona and New Mexico are energy rich, particularly New Mexico. Data is presented establishing the reigions position with respect to coal, oil, gas and uranium resources. Further, this status is reflected in current patterns of energy production, data on which are presented. Additionally, price information is presented which explains, in part, current energy production patterns in the region.
As electricity demand increases, policymakers must make decisions about which energy resources will meet future demands. Much of the recent literature has focused on the contribution of new coal power plants to carbon emissions (Milford et al., 2005; Milford et al., 2007; MIT 2007). However, policymakers and industry are increasingly interested in job creation and economic development analyses to understand the full impacts of new electricity generation projects.1 Additionally, economic development impacts are often a critical piece in building public support for wind power projects. The purpose of this research is to look at the specific factors that drive wind-power-related economic development and to better understand...

Biomass is the first-ever fuel used by humankind and is also the fuel which was the mainstay of the global fuel economy till the middle of the 18th century. Then fossil fuels took over because fossil fuels were not only more abundant and denser in their energy content, but also generated less pollution when burnt, in comparison to biomass. In recent years there is a resurgence of interest in biomass energy because biomass is perceived as a carbon-neutral source of energy unlike net carbon-emitting fossil fuels of which copious use has led to global warming and ocean acidification. The paper takes stock of the various sources of biomass and the possible ways in which it can be utilized for generating energy. It then...
Norway has administered its petroleum resources using three distinct government bodies: a national oil company engaged in commercial hydrocarbon operations; a government ministry to direct policy; and a regulatory body to provide oversight and technical expertise. Norway's relative success in managing its hydrocarbons has prompted development institutions to consider whether this “Norwegian Model” of separated government functions should be recommended to other oil-producing countries. By studying ten countries that have used widely different approaches in administering their hydrocarbon sectors, we conclude that separation of functions is not a prerequisite to successful oil sector development. Countries where...
This paper provides an overview of issues and opportunities associated with the use of biomass for electric power generation. Important physical characteristics of biomass and waste fuels are summarized, including comparisons with conventional fossil fuels, primarily coal. The paper also provides an overview of the current use of biomass and waste fuels for electric power generation. Biomass and waste fuels are currently used for approximately 9800 MW of electric generating capacity, including about 6100 MW of capacity fueled by wood/wood waste and about 2200 MW of capacity fueled with municipal solid waste. Perspectives on the future availability of biomass fuels (including energy crops) are addressed, as well...
