Not sure if I believe the statistics here to be honest, not really sure if bitcoin transactions take up that much electricity, seems quite a bit exaggerated to be honest.

Also, it's not just BTC. A lot of the world produces energy via the burning of fossil fuels, which is easy and fairly cheap to do, but of course, is impactful to the enviroment.

The first step here is for the big companies to stop with their huge carbon footprints, and need to swap to renewable energy sources like wind (windmills), or water (Hydroelectric) - and this technology needs to be applied towards bitcoin mining.
