Cost of Firewood
See informative article:
Firewood usage is large - about 5 cords per year. Each cord is 2500-5000 lb. That makes 12,500 to 25,000 lbs - or 6-12 tons.
There are 12 million wood stoves in the USA.
Average gallons of fuel use in the USA is 10,000 miles equivalent - or 500 gallons - or 4000 lb of fuel. That is the equivalent of wood house heating usage.
Cost of a cord is $150-$500 - say $300 on avearage.
5 cords is $1500 for a season of wood heating.
Gas heat for the winter is about $700.
One season of firewood gets you 5kW of installed electricity from solar panels at the current price of 30 cents per watt at http://sunelec.com. Makes sense to use electric PV heat and save some trees.
