    4. Instability of supply – war, hurricane (refining capacity), global competition Rising Costs – global competition (China, Indonesia, India) Supplies – economic limitations and long-term absolute shortages, nothing imminent, and alternative technologies take decades Climate Change – increasing evidence and support for role of fossil fuels in climate changeInstability of supply – war, hurricane (refining capacity), global competition Rising Costs – global competition (China, Indonesia, India) Supplies – economic limitations and long-term absolute shortages, nothing imminent, and alternative technologies take decades Climate Change – increasing evidence and support for role of fossil fuels in climate change

    42. Lowest hanging fruit is in the HEAT sector. Yellow is from biomass. Why is the US NOT focusing on heat? Lowest hanging fruit is in the HEAT sector. Yellow is from biomass. Why is the US NOT focusing on heat?

    43. Definition of “bio district heat” vs. “district heat” AND “bio-industrial” vs. “industry”? Note the large growth in district heating since the early 1980s. Industry is mostly pulp & paper. Note the RISE in district heating . . . and recent inroads into transportation.Definition of “bio district heat” vs. “district heat” AND “bio-industrial” vs. “industry”?

    44. Example of a small heat-only district plant. Again, heat is the main objective, not electricity. By-products from sawmills, bark, etc. About a $2.5 million investment (not including the grid) Example of a small heat-only district plant. Again, heat is the main objective, not electricity.

    45. Example of a large CHP plant . . . active for over 35 years!!! 20,000 inhabitants Note: Marquette plant 600+ MW, coal, ½ to mines. Entirely city-owned. 90% of UP electricity (incl. pulp & paper mills?) 3 boilers. 1 boiler (winter operated) burns biomass. Source: Wikipedia 44,000-55,000 green tons consumed/year. Heats almost entire city. Powers about half the city. Annual heat & power cost to residences about $3700.

    47. One of the world’s largest pellet plants . . . most is actually export to Europe. Next door is a pulp plant than accepts chips. Buys about 2000 cords/day. Feedstock cost is about 50% of pellet cost. Presses produce about 25 tons/hour. One of the world’s largest pellet plants . . . most is actually export to Europe.
