      someone asked for me to explain the math, so here is a short thread detailing a simple model using publicly known numbers: the current Bitcoin network hashrate is around 50 exahashes/sec the most common mining hardware is still the S9 antminer which churns out ~13 terahashes/sechttps://twitter.com/ofnumbers/status/1032350035701161984 …

      Tim Swanson added,

      Can't simultaneously say that Bitcoin is - as measured by hashrate - the "most secure public chain" and in the same breath say the miners don't consume enormous quantities of energy. The fundamental problem with PoW maximalism is that it wants to have a free energy lunch. https://twitter.com/danheld/status/1032322008854421504 …

      Right.. but what if you're using a renewable energy source that couldn't have been used for something better anyway? Then it is essentially extra security to the network "for free"

      (1) that assumes that all PoW miners will gravitate towards renewable resources and there isn't much evidence that his occurring (yet) (2) the scenario above still doesn't factor in the tremendous e-waste generated from millions of single-use ASIC systems with ~12 month lifecycle

      Renewable is displacement. Renewable used by bitcoin network is still renewable not used by more necessary everyday infrastructure. Since traditional global energy consumption is still going up, that ensures demand for fossil continues to increase.
