There is much loose talk in the vertical-gardening world about using renewable energy sources to power their grow-lights. That discussion spirals into some interesting circular logic: that we would use solar arrays and wind farms to convert sunlight’s energy into electric current that would feed lamps that would convert a portion of the electrical energy into artificial sunlight to shine on plants so they can convert that light energy into food. At each of those conversion points, there are big losses of energy and heavy infrastructure costs. It’s about as wasteful as a system can be. Better to let crop plants do what they do best: capture cost-free, emissions-free sunlight for themselves, directly. The roots of urban food insecurity are as economic and political as those out here in farm country. Sun-fed urban gardening, fruit and vegetable cultivation close to cities, and people’s food initiatives all are important and need to keep expanding, but a still more profound economic transformation is needed.
