It's probably no surprise, but the water footprint of bioenergy is the largest of any energy generation, due to the amount needed to cultivate crops. However bioenergy is still twice as water-efficient as the production of biofuel.

Methane reductions of up to 18 percent have been recorded across 15 dairy farms in Vermont trialling a grain seed mix including plants such as alfalfa and flaxseed - plants which, unlike corn and soy, mimic the spring grasses that animals evolved to eat.
