If you are in the Pacific N.W. I'm assuming that your winters are pretty mild.
If you build your own structure, you will not need a furnace.
There are a lot of good books and publications around that show how to 
construct affordable and sustainable greenhouse operations.
Burning fossis feuls might be needed if you wish to provide artificial 
lighting to plants during the winter.

The Growing Edge published an article (Spring 94) about a lady on
Martha's Vinyard who operates a greenhouse all year-round without the 
aid of a furnace.  She developed this system after her wood-stove 
heated greenhouse and house burnt down.
The winters on the East coast are absolutely brutal, yet she is thriving.
She uses chickens to provide heat CO2 and eggs, hence no cost to
the ecosystem or her pocket book.

>From  the introduction:"...all greenhouses are in fact solar.  However,
traditionally designed greenhouses have rarely been concerned with the
most effective use of the sun's energy.
   basic elements in the design and operation of each of our
   greenhouses:
      The most efficient collection of solar energy.
      The storage of solar energy.
      The reduction of heat loss during and following colleciton periods.
   benefits:
      Surplus thermal energy produced in winter can be used immediatly in
      an adjoining structure or stored for later use.
      Independence from mechanical heating and cooling devices powered
      by fossil feuls.
