so using renewable energies will not give you an additional advantage or more profits.
Because renewable energy can be cheaper.
Electricity is expensive to store. Imagine a giant wind farm. During the day, it churns out electricity which homes and business use to power lighting, AC, computers, TVs, kitchen appliances, etc. During the night, it churns out just as much electricity, but the demand is now tiny. They spend lots of money to build batteries to store some of this excess, but it's not enough. A lot goes to waste. Along comes a bitcoin miner and says "I'll move a bunch of my mining equipment here if you sell me your excess electricity cheaply." This is electricity which is being wasted and earning the renewable energy company nothing, so selling it at any price is good for them.
Why do some miners leave or use solar energy?
Because it is very easy to run your own solar panels. Buy some panels, hook them up to your mining equipment, off you go. No ongoing raw material requirement, no moving parts, very little maintenance or upkeep, very little ongoing costs.
