Advancements in mining hardware have led to greater-energy-efficiency. Newer ASIC miners use less electricity for higher hash rates, reducing the energy consumption/Bitcoin mined.
That's well said but the new devices cost a lot, I've tried to enter the mining setup somehow but after full-time research on the local market and the expenses, I think I cant afford even an entry-level mining ring. Even if somehow I can arrange a mining ring the current electricity costs in my locality are skyrocketing and seem like they are inspired by the Halving cycle of the Bitcoin because every 6 months they boost the taxes and per unit prices.
Hmm, trying to figure out if somehow on the cloud I can rent a few high-end devices where I can get rid of these taxes and energy costs. Still searching for such a platform but until now I haven't discovered any authentic one according to my need and convenience.
