To answer your first question. All of the above. It really is a small operation when you compare it to the cash crop farms and large dairies around here. I have been cash cropping for over 20 years and despite our little windfall with high prices and big yields the last couple of years. Inputs keep going up. Looking to simplify and maintain profits without making the fertilizer company rich.
As far as energy goes, I'm looking to conserve more on the farm but to be off grid is realistic. The house is a different story we look on doing this in a couple years. Starting by determining how much electricity we are consuming and trying to conserve more now. I'm hesitant to install solar panels now because you always hear about the breakthrough in technology is coming and it will cost less in the future. At some point you have to bite the bullet, I don't know when we will be there.
