Answer 1

Heat is just energy, and heating/cooling things is just a transfer of energy.

When you heat something, you’re adding energy, but to cool something you need to create an environment where the target object has more energy than something else, so that it transfers that energy. Creating that environment uses a lot more energy than simply imparting the energy directly.
