Ethereum's proof of work algorithm was different to that of Bitcoin's, so Bitcoin ASICs could not be used to mine Ethereum and vice versa. Ethereum becoming more centralized with PoS is irrelevant to Bitcoin's hashrate.
In general, ASIC miners are only created for certain crypto assets, so if ASIC Miners are Bitcoin they can only mine Bitcoin.
Simply put, an Application-specific Integrated Circuit (ASIC) is an integrated Circuit Chip that has been specifically designed for specific crypto mining purposes.
ASIC chips used in mining crypto assets are becoming more efficient, with the latest generation operating at around 29.5 joules per terahash.
The most popular ASIC Mining Bitcoin is Antminer S9 which was released in 2016.
and for ASIC Mining Bitcoin the best hashrate for now is:
- Antminer S19, which has a hash rate of 95 TH/s (tera hashes per second)
- S19 Pro with 110 TH/s and T19 with 84 TH/s.
Other competitors include WhatsMiner M30S++ (112 TH/s)
- Canaan AvalonMiner 1246 (90 TH/s).

And about the renewable energy used by bitcoin miners today, it will certainly have a good impact on the environment without burdening conventional electricity, because they already have their own renewable energy source. Like El Salvador, which is intensively mining bitcoin, they are determined to use renewable and environmentally friendly energy. Such as the use of hydroelectric power, wind, solar and tidal water.
The Salvadoran government in September began harnessing geothermal energy for bitcoin mining from a factory at the base of the Tecapa volcano, 106 kilometers (66 miles) east of the capital, owned by a company that is part of CEL (Comisión Ejecutiva Hidroeléctrica del Río Lempa)
The plant produces about 102 megawatts, and the government plans to add another five megawatts next year. Currently, 1.5 megawatts are allocated for bitcoin
