This study considered three aspects of residential wood energy use in Alaska: current conditions and fuel consumption, knowledge and attitudes, and future use and conditions. We found that heating oil was the primary fuel for home heating in southeast and interior Alaska, whereas natural gas was used most often in south-central Alaska (Anchorage). Firewood heating played a much more important role as a secondary (vs. primary) heating source in all regions of Alaska. In interior Alaska, there was a somewhat greater interest in the use of wood energy compared to other regions. Likewise, consumption of fossil fuels was considerably greater in interior Alaska. Cost was a primary factor influencing motivation to convert to wood energy. Most respondents were at least somewhat familiar with residential wood-burning systems, however relatively few were familiar with Environmental Protection Agency certified woodstoves. Firewood/cordwood was by far the preferred wood fuel choice, whereas wood briquettes were least preferred. Similarly, firewood was the type of wood fuel that respondents were most familiar with. Variations were observed between Alaska's primary regions (southeast, south-central, and interior).

Variations were observed between Alaska's primary regions (southeast, south-central, and interior). This could be attributed to a number of factors including colder climates in interior Alaska, and overall low use of wood energy in south-central Alaska because of preferences for natural gas. Fuel oil prices of $4.00 to $5.00 per gallon would be needed for most homeowners to convert to wood heating. There was a broad range of willingness to pay for new wood energy systems (from about $1,000 to $3,000). However, this survey was not random and results may not be representative of the populations at each sampling location.

The inadequate transportation infrastructure and undeveloped markets for sawmill residues in southeast Alaska are among the factors that limit the use of this forest resource. This study considers the potential use of sawmill residues to supply two bioenergy systems that would produce thermal energy for (1) community heating and (2) a lumber dry kiln in Hoonah, Alaska. The proposed community heating system would be a direct combustion system, burning approximately 1,450 green tons (1.315 green metric kilotons) of wood fuel per year to provide heating for seven centrally located buildings in Hoonah. Additional sawmill residues would be used in another system to provide process heat for a proposed 25,000 board foot (41.3 m3) dry kiln. The Hoonah sawmill typically produces as much as 5 million board feet (8,255 m3) of lumber per year, primarily from western hemlock and Sitka spruce. The processing of this amount of lumber would result in an adequate volume of residue to provide a fuel source for the heating requirements of the proposed projects. Wood residue from the sawmill is assumed to be available at no cost other than for transportation. Use of wood fuel for community heating would save an estimated 65,000 gallons (2.47 kL) of heating oil per year. Avoided fuel costs would be approximately $91,500 per year based on No. 2 fuel oil at a market price of $1.40 per gallon ($0.37 per liter). Based on a project life of 25 years and a contingency rate of 25%, the expected after-tax internal rate of return (IRR) for the community heating portion of the project is 29.6%. Total installed costs for the 1,195,000 Btu/h (350 kWthermal) community heating system, including distribution piping and its installation and backup oil systems, are estimated to be $631,000. For the lumber dry kiln, in the second heat-generating system, economic results were less favorable, with expected energy savings of $82,900 per year and an after-tax IRR of 24.1% (also assuming 25% contingency). Estimated installed cost of the 1,536,000 Btu/h (450 kWthermal) dry kiln system with a backup oil system is $513,800.

This report is concerned with the existing volumes of renewable wood energy products (RWEP) currently used in Alaska and the potential demand for RWEP for residential and community heating projects in the state. By using peak prices from the fall of 2008, the potential value of a British thermal unit (Btu) from various fuels has been calculated to identify those situations where wood-based fuels are economically competitive or advantageous when compared with alternative fuel sources. 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. Charts and tables. This is a print on demand edition of an important, hard-to-find report.

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 report is concerned with the existing volumes of renewable wood energy products (RWEP) that are currently used in Alaska and the potential demand for RWEP for residential and community heating projects in the state. In this report, data published by the U.S. Department of Commerce, Bureau of Census and the U.S. Department of Energy, Energy Information Agency have been used to build a profile of residential and commercial energy demand for Alaska census tracts. By using peak prices from the fall of 2008, the potential value of a British thermal unit (Btu) from various fuels has been calculated to identify those situations where wood-based fuels are economically competitive or advantageous when compared with alternative fuel sources. Where these situations are identified, the Btu usage has been converted to equivalent volumes of wood energy products. Data have been presented so potential demand is available by census tract. No attempt has been made to define the rate of conversion or the time that it will take for total conversion to renewable wood energy. The ultimate rate of conversion is a function of government policies that encourage conversion, costs associated with converting, and price of alternative fuels. 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. If all of the liquid fuels used by the residential and commercial sectors in Alaska were converted to solid wood energy, it is estimated that 1.3 million cords of material would be required annually.

This Intergovernmental Panel on Climate Change Special Report (IPCC-SRREN) assesses the potential role of renewable energy in the mitigation of climate change. It covers the six most important renewable energy sources - bioenergy, solar, geothermal, hydropower, ocean and wind energy - as well as their integration into present and future energy systems. It considers the environmental and social consequences associated with the deployment of these technologies and presents strategies to overcome technical as well as non-technical obstacles to their application and diffusion. SRREN brings a broad spectrum of technology-specific experts together with scientists studying energy systems as a whole. Prepared following strict IPCC procedures, it presents an impartial assessment of the current state of knowledge: it is policy relevant but not policy prescriptive. SRREN is an invaluable assessment of the potential role of renewable energy for the mitigation of climate change for policymakers, the private sector and academic researchers.

The goals of the second volume of the AHDR – Arctic Human Development Report: Regional Processes and Global Linkages – are to provide an update to the first AHDR (2004) in terms of an assessment of the state of Arctic human development; to highlight the major trends and changes unfolding related to the various issues and thematic areas of human development in the Arctic over the past decade; and, based on this assessment, to identify policy relevant conclusions and key gaps in knowledge, new and emerging Arctic success stories. The production of AHDR-II on the tenth anniversary of the first AHDR makes it possible to move beyond the baseline assessment to make valuable comparisons and contrasts across a decade of persistent and rapid change in the North. It addresses critical issues and emerging challenges in Arctic living conditions, quality of life in the North, global change impacts and adaptation, and Indigenous livelihoods. The assessment contributes to our understanding of the interplay and consequences of physical and social change processes affecting Arctic residents’ quality of life, at both the regional and global scales. It shows that the Arctic is not a homogenous region. Impacts of globalization and environmental change differ within and between regions, between Indigenous and non-Indigenous northerners, between genders and along other axes.

In the United States, some populations suffer from far greater disparities in health than others. Those disparities are caused not only by fundamental differences in health status across segments of the population, but also because of inequities in factors that impact health status, so-called determinants of health. Only part of an individual's health status depends on his or her behavior and choice; community-wide problems like poverty, unemployment, poor education, inadequate housing, poor public transportation, interpersonal violence, and decaying neighborhoods also contribute to health inequities, as well as the historic and ongoing interplay of structures, policies, and norms that shape lives. When these factors are not optimal in a community, it does not mean they are intractable: such inequities can be mitigated by social policies that can shape health in powerful ways. Communities in Action: Pathways to Health Equity seeks to delineate the causes of and the solutions to health inequities in the United States. This report focuses on what communities can do to promote health equity, what actions are needed by the many and varied stakeholders that are part of communities or support them, as well as the root causes and structural barriers that need to be overcome.
