Alternatives to Propane or Electric stoves/ovens

We are very interested in "The Living Building Challenge" as we are building a home that is very close to meeting the prerequisites. Since we will be producing all of our own electricity we are not keen to have an electric cooking stove. Propane was going to be the other option to fuel the cooking stove but this would eliminate our status of "Net Zero". Does anyone out there have another option for our main inside cooking stove and oven? We do have and use a cob oven outside (wood fired of course) and plan on a solar cooker but we still require a stove and oven inside.
