If you had electric pokemon farms, you would go from having an energetic crisis to a food crisis, a health crisis (the rooting increases diseases), and a pollution crisis.
The most ecologically sustainable in that world is to have flocks/herds of Magnemite (Magneton and Magnezone are more difficult to control) touring land whipped by electric storms, fattening them and draining the exedent. The problem, these do not occur often, are unpredictable and are not available for all regions.
