The energy consumption in Bitcoin mining is not due to the consumption of the computing equipment that solves the puzzles, but rather to the cooling equipment and the heat dissipated by the computing equipment.

Miners are looking for solutions that not only represent an economic improvement, but also an ecological one. Among them is the use of renewable energy and moving mining complexes to cold places on the planet and using the energy in the form of dissipated heat to heat those who are nearby.

Bitcoin does not pollute, it cooperates.
