Energy consumption is much into discussion these days, and the big controversy is now once again getting shattered by Elon Musk. It is also stated that, banks now consume more power than the bitcoin and other cryptocurrencies. With time, efficiency is getting achieved on bitcoin mining equipments. Based on this I don't think energy consumption will set to be a big issue in the future.
Exactly. I don't get what the big deal is about Bitcoin's energy consumption, when existing financial institutions consume more energy than Bitcoin on a daily basis. It's all failed attempt to spread FUD in order to lure people away from Bitcoin and cryptocurrencies in general. Bitcoin can be much greener than what it is right now, if miners rely on alternative energy sources. Imagine how Bitcoin would benefit the environment if most ASIC machines relied on solar or wind energy. With how fast our world is changing, we might see this become a reality sometime in the future. Since PoW is the most secure (and decentralized) consensus algorithm to date, it's hard to believe Bitcoin will switch to PoS anytime soon. On the contrary, Bitcoin will remain as a PoW cryptocurrency while the rest of the altcoins will switch to PoS in order to "tackle" the high energy consumption. Ethereum will switch to PoS, and other PoW-based cryptocurrencies will follow as the PoS hype comes into fruition. I wouldn't worry about Elon Musk abandoning Bitcoin in favor for another altcoin, as long as the pioneer cryptocurrency as some loyal supporters behind it. Just my opinion
