Of course it is. If it costs a miner $10k in electricity, rent etc to mine 1 BTC, they will need to sell at least $10k worth of BTC to cover their cost. If they stop mining, they will have less pressure to sell.
Miners hold over 2mm BTC so hard to see how their actions have no direct impact on price.
My point, is that when electricity costs approach zero, more people will mine which will impact prices.
