- mapt 2y agoYeah, this highly optimized passive solar design is one of those things that seems very obvious when energy is too expensive to waste on international transportation or excessive heating in a cold climate. Citrus production in 40 below zero. By pursuing artificially inexpensive energy we are doubling down on a great number of wasteful practices that are largely avoidable.
