The average family will save about 22 gallons of gasoline per year by having a compost tumblers .   This comes from adding up all of the energy used by the heavy equipment needed to mine or dig up the raw materials for industrial fertilizers, energy used for processing these materials, energy used for transporting them to warehouses and for packaging and shipping, whether in bags or in bulk, energy used for turning nitrogen and natural gas into ammonia, and finally, the energy used by all the garbage trucks that eventually haul most of this stuff to the landfill once it is discarded.  The compost tumbler circumvents all of this, by keeping all of the organic in a local area.  Next I plan to calculate how much total energy could be saved if everyone did composting.
