The laws of thermodynamics don't allow it. Energy usually comes with entropy attached, which can't be destroyed and has to be dumped somewhere. At a colder temperature you need less energy to raise the entropy, which allows for energy and entropy to be split into a cold part (containing most of the entropy and some energy) and a hot part (containing low entropy) at specific ratios. Electricity is low-entropy energy, which is why it's so useful.
