If we were to turn on EVERY single miner ever built - 100% of the time, we get a much higher energy consumption figure than is actually the case.
   All makes and models of ASIC equipment have been listed (many thanks to "anonymous otter"). I added the estimated quantity of ASICs produced & multiplied it by the estimated up time the mines are in operation then matched it to the current total hash rate. This  can then be used to approximate the average hash efficiency.
   New mining gear will be driven hard, then sold when less profitable to amateurs, home miners, hobbyist & home / business heating. A brand new mine in an industrial mining unit would have much more up time say 98% than an amateur using a 5 year old ASIC for heating say 30%.

   Mining equipment varies in performance-

• amazing performance yet to be released may be being "tested" by the manufactures
• Newly released
• Older less profitable
• Obsolete
• Hashing for non Bitcoin networks.

This simple changing of incentives could rewire the human psyche. People become incentivised by thrift rather than consumption. The benefit of de-growth to the climate cause could be immeasurable.

   The closer you are to the money printing press the richer you are likely to be. Why is it that we can buy beans grown in Africa, picked - put in a plastic package - ship round the world, cheaper than growing in our own gardens in the US/UK ? Or minerals mined cheaper than in our own countries?
Simple 

   Bitcoins power consumption serves three purposes 

• Mining new coins           96%  (Like mining gold out of the ground)
• Performing transactions   4%  (Like melting, verifying /distributing gold bars and coins)
• Blockchain nodes almost 0%  (Like an accounting ledger)

    By 2028 over 98% coins will be mined and in circulation, by 2140 virtually all Bitcoin will be mined. Subsequent Halvening's coupled with Tech advances will make it much easier to simply buy rather than mine, the power consumption should drop as the block reward drops & the tech entry level increases. Miners will then be mostly hashing for increasing transaction fees + a increasingly tiny block reward, the "Gold Rush" will be over considerably reducing hashing. Leaving the world with a much more slim-lined incorruptible economic backbone of world money.
    No more bailouts ! The real cost of Banks.

   In the future Technological improvements will increase the hash rate, and not so much brute Wattage.

   Roughly 39,000 tonnes of ASIC mining machines have been manufactured in total. Approximately half of that mass is still in use. If these replace heating units, much of this could be offset by not manufacturing boilers, storage heaters etc.

   Giving a very useful outlet for excess wind, solar (see Sunexchange) and hydro power. In the UK and Germany people are actually PAID TO CONSUME excess wind power, imagine getting paid twice to use power!
   In the UK Octopus Energy Agile tariff can go to -3p /kWh. The mining equipment does not need to run 24/7 and can be quite happily turned off when little renewable energy is available. Load switching/ balancing is hugely advantageous to renewables.

   Emissions are also entirely dependent on electrical carbon intensity. The average UK carbon intensity for 2020 was 181gCO2 /kWh.

   As the price rises will Bitcoins energy consumption rise ?

   I think we may actually be at peak mining energy consumption for the following reasons. 

• Mining equipment has got really expensive - $11,620 for Bitmain S19 xp
• Typically Bitcoins value increases roughly 140% every year ! Compound interest rates on steroids !
• Instead of investing in mining equipment, wages, electricity over the next few years, with a rapidly rising price it may simply be much better investment to simply buy BTC IMMEDIATELY .
• Research & development for the next generation of ASIC's is even more expensive than mining.

   In the early days the mining reward was much greater ( 50BTC ) so was worth the investment, but now if you are a company like Bitmain looking to invest in Research & Development to bring the next generation of ASIC to market, would you employ staff, buy machinery costing millions$ or simply buy & hold and go on holiday and make FAR MORE money?
​
   I do not see a huge increase in mining energy consumption and quite possibly a reduction. ASIC mining gear is fetching highly inflated prices at the moment. Some people may actually sell there gear to invest in the coin its self. Hash rate may increase as old slow ASICs are replaced for new ones. Major innovations from Bitmain or anyone else seem a long way off at the moment.

This survey by University Of Cambridge shows Bitcoin is powered by 39% renewables but rather confusingly talks about Bitmain Antminer S5 & S7 (2015 out of date mining hardware)
