If btc required switzerland's worth of energy to mine a block - how on earth did satoshi mine blocks in 2009 all alone by himself?
the answer is that bitcoin doesn't require any amount of energy beyond a single computer to churn out blocks. all the energy usually attributed to being "used" by bitcoin is in fact energy purchased by users to acquire and/or maintain certain level of security of their financial assets.
bitcoin is simply an instrument through which security of financial assets can be expressed in form of pure energy, which is completely transparent and can't be faked. that security comes for a price and as long as users are willing to pay this much money for that amount of security - miners will continue producing it, consuming energy in the process.
