Available in PDF, EPUB and Kindle. Book excerpt: In rural Alaskan communities, high economic, social, and ecological costs are associated with fossil fuel use for power generation. Local concerns regarding fuel prices, environmental contamination, and the effects of global climate change have resulted in increased interest in renewable energy sources. In this study we assessed the feasibility of switching from fossil fuels to wood energy in rural Alaskan villages in forested regions of interior Alaska. Modeling results based on recent data on rural energy use, demographics, economics, and forest dynamics indicated that the installation costs of biomass systems would be recouped within 10 years for at least 21 communities in the region. In addition, results showed that all but the largest remote communities in the interior could meet all their electrical demand and some heating needs with a sustainable harvest of biomass within a radius of 10 km of the village. Marketable carbon credits may add an additional incentive for fuel conversion, particularly if U.S. prices eventually rise to match European levels. Biomass conversion also offers potential social benefits of providing local employment, retaining money locally, and reducing the risk of catastrophic wildfire near human habitation. This analysis demonstrated that conversion to biomass fuels is economically viable and socially beneficial for many villages across interior Alaska.

Available in PDF, EPUB and Kindle. Book excerpt: "The study site was a permafrost-free upland site with an east-northeast aspect, west/northwest of Fairbanks at mile 10 on the Cache Creek road in a mixed hardwood/spruce stand of Betula neoalaskana Sarg., Populus tremuloides Michx., Populus balsamifera L., Picea glauca (Moench) Voss, and Picea mariana (Mill.) BSP. In treatments designed to encourage hardwood growth, four different methods were used for removing vegetation (shearblading, masticating head, drum-crusher, and chainsaw thinning), resulting material was then left in place, burned, or chunked and removed. Treatments were evaluated using man/machine hour and dollar cost data and Permanent Sample Plot (PSP) data. PSPs were installed within six different fuels conversion treatments and a control for monitoring purposes. A pilot study revealed that debris pile burning changed soil color (more red) and soil water repellency properties. All treatments that had one full growing season showed hardwood regeneration. Shearblading and leaving material on site was the least labor-intensive treatment and least costly. Burning windrows was the least labor-intensive and least costly method of removing material from the site"--Leaf iii.

Book excerpt: Biomass resources in Alaska are extensive and diverse, comprising millions of acres of standing small-diameter trees, diseased or dead trees, and trees having lowgrade timber. Limited amounts of logging and mill residues, urban wood residues, and waste products are also available. Recent wildfires in interior Alaska have left substantial volumes of burned timber, potentially usable for biomass energy. Motivated, in part, by rising fuel prices, organizations across the state -- including businesses, schools, and government agencies -- have all expressed an interest in wood energy applications. Numerous sites have pursued feasibility studies or engineering design analysis, and others have moved forward with project construction. Recent advances in biomass utilization in Alaska have been enabled by numerous factors, and involve various fuel sources, scales of operation, and end products. Already, thermal wood energy systems are using sawmill residues to heat lumber dry kilns, and a public school heating system is in operation. Management policies on national forests and state forests in Alaska could determine the type and amounts of available biomass from managed forests, from wildland-urban interface regions, and from salvage timber operations. Biomass products in Alaska having potential for development are as diverse as wood pellets, cordwood (firewood), compost, wood-plastic composite products, and liquid fuels. In addition, new technologies are allowing for more efficient use of biomass resources for heating and electrical generation at scales appropriate for community power. This case study review considers successes and lessons learned from current wood energy systems in Alaska, and also considers opportunities for future bioenergy development.

Download or read book Forest Dynamics and Conservation written by Manoj Kumar and published by Springer Nature. This book was released on 2022-05-16 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book unveils forestry science and its policy and management that connect past and present understanding of forests. The aggregated knowledge is presented to cover the approaches adopted in studying forest structure, its growth, functioning, and degradation, especially in the context of the surrounding environment. The application of advance computation, instrumentation, and modelling has been elaborated in various chapters. Forest ecosystems are rapidly changing due to forest fires, deforestation, urbanization, climate change, and other natural and anthropogenic drivers. Understanding the dynamics of forest ecosystems requires contemporary methods and measures, utilizing modern tools and big data for developing effective conservation plans. The book also covers discussion on policies for sustainable forestry, agroforestry, environmental governance, socio-ecology, nature-based solutions, and management implication. It is suitable for a wide range of readers working in the field of scientific forestry, policy making, and forest management. In addition, it is a useful material for postgraduate and research students of forestry sciences.

Download or read book The Potential for Wood Energy and Biomass Fuels in Alaska written by Dmitry S. Halinen and published by Nova Science Publishers. This book was released on 2011-10 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Goal three of the current U.S. Department of Agriculture, Forest Service strategy for improving the use of woody biomass is to help develop and expand markets for woody biomass products. This book explores the existing volumes of renewable wood energy products (RWEP) that are currently used in Alaska and the potential demand of RWEP for residential and community heating projects in the state. Data published by the U.S. Department of Commerce, Bureau of Census and the U.S. Department of Energy have been used to build a profile of residential and commercial energy demand for Alaska census tracts. If fuel oil prices increase to the levels experienced in 2008, there would be a strong economic incentive to convert heating systems to use solid wood fuels.

Download or read book Biomass Estimates for Five Western States written by and published by . This book was released on 1990 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this report is to describe the woody biomass resource within US Department of Energy's Pacific Northwest and Alaska Regional Biomass Program, comprised of southeast Alaska, Idaho, Montana, Oregon, and Washington. In addition to the regional forest biomass assessment, information will be presented for logging residue, which represents current energy conversion opportunities. The information presented in the report is based on data and relationships already published. Regionally applicable biomass equations are generally not available for species occurring in the west. Because of this, a number of assumptions were made to develop whole-tree biomass tables. These assumptions are required to link algorithms from biomass studies to regional timber inventory data published by the Forest Inventory and Analysis Research Units (FIA), of the Pacific Northwest and Intermountain Research Stations, US Forest Service. These sources and assumptions will be identified later in this report. Tabular biomass data will be presented for 11 resource areas, identified in the FS inventory publications. This report does not include information for the vast area encompassing interior Alaska. Total tress biomass as defined in the report refers to the above ground weight of a tree above a 1.0 foot stump, and exclusive of foliage. A glossary is included that defines specific terms as used in the report. Inventory terminology is derived from forest inventory reports from Forest Inventory and Analysis units at the Intermountain and Pacific Northwest Research Stations. 39 refs., 15 figs., 23 tabs.
