Studies of fat cells and thyroid cells show that fat cells have fewer mitochondria than thyroid cells. A biologist would most likely infer that fat tissue does not require energy
requires less energy than thyroid tissue
has energy requirements equal to those of thyroid tissue
requires more energy than thyroid tissue

The thyroid plays an important role in regulating the body's metabolism. The hormones it secretes help govern many functions of the body like how the body produces heat, consumes oxygen, and uses energy.

Virtually every tissue in the body is affected or regulated by thyroid hormone. Think where mitochondria are found in the greatest numbers - they are found (for example) in liver cells, kidney cells, muscle cells, etc. These tissues carry out a lot of work and thus require lots of energy. Fat is a storage product that sits there until required but the thyroid does lots of work involved in metabolism and therefore requires plenty of energy.
