A detailed study is presented of the availability and use of wood as an energy resource for the State of Maine. Although there are no good data on the total resources of Maine's forests, the best estimates indicate that one could obtain about 1/2 quad (10/sup 15/ Btu) per year from thinning overstocked stands and harvesting dead trees; current logging operations could produce about the same amount of energy in the form of logging residues and thinnings, an amount that could be increased manyfold by intensive forest management. The costs of wood for fuel can be estimated on the basis of current logging and transportation costs. The corresponding energy prices, while high, are competitive with current fossil fuel prices. Using any energy source requires not only the fuel but also a furnace. The total energy costs are thus not only the cost of current fuel use but also those of the capital investment in the furnace. We have estimated these for systems of two sizes, one for a small house, the other for an apartment building or small commercial establishment. In both cases, our estimated indicate, that woodfueled systems can be economically competitive. Wood is currently used as a fuel on a large scale in the pulp and paper industry. With some increase in wood harvesting efforts and some alterations of furnaces that industry could achieve energy self sufficiency. Other large-scale uses are still speculative but deserve further investigation. A state-owned energy corporation could serve to provide a market for currently wasted wood and to investigate the conversion of wood to other forms of energy. The combustion of wood is not associated with environmental effects that are different kind in magnitude from those associated with the combustion of fossil fuel.
This publication highlights the use of wood for energy and includes the most recent statistics on wood energy markets across the UNECE region. It aims to communicate the relevance of wood energy in the region and help bridge information about the forest and energy sectors. It also intends to offer some of the best-available information on the role that wood energy can play in various sectors to support environmental, energy, and socio-economic strategies toward a greener economy. It focuses on commercial wood energy uses in the UNECE including energy generated for cooking, heating and electricity generation.
Wood as an Energy Resource analyzes how wood is seen as a possible source of alternative energy and evaluates the extent of its use. The book covers the trends of wood as fuel in different countries, including its current use, value as fuel, comparison with other fuels, supply, delivery, and transportation. Wood conversion to other forms of fuel and the deployment of advanced wood combustion and conversion systems are also discussed. The text also explains wood resource bases and supplies, as well as the future of wood as fuel. The monograph is highly recommended for experts and researchers in energy conservation as well as renewable and alternative energy sources, especially for those who want to make studies regarding this topic. The book will also be helpful for advocates and environmentalists who want to be educated and educate others about wood as source of energy and fuel.
