Top-freezer refrigerators feature a freezer shelf at the uppermost part of the unit, contrary to bottom-freezer refrigerators. However, aside from freezer placement, they also differ in energy consumption.
Top-freezer refrigerators use 10% to 25% LESS ENERGY, making them energy-efficient choices and cheaper to operate. But, if you're looking for more freezer space, bottom-freezer fridges are the one to go for.
