Fuel costs

Biomass waste fuel costs vary widely but estimates across the USA suggest that the cost in North America is between $25/dry tonne and $60/dry tonne. Sawmill waste used close to the process plant might be obtained even more cheaply, for perhaps $17/dry tonne.

More important from a long-term perspective is the cost of energy crops. Table 15.3 shows some typical costs from around the world, but these figures should be used as a broad guide only, since the methods by which they were evaluated are not all directly comparable. As the table shows, costs can vary between $1/GJ and $5/GJ. Coal costs around $2/GJ.

In the USA, experimental projects suggest that switchgrass might be delivered for as little as $2.1/GJ and wood for $3.3/GJ. On this basis, switchgrass would be almost competitive with coal, but wood does not appear to be competitive yet.

Do we really want the one thing that gives us its resources unconditionally to suffer even more than it is suffering now? Nature, is a part of our being from the earliest human days. We respect Nature and it gives us its bounty, but in the recent past greedy money hungry corporations have made us all so destructive, so wasteful.
