Wu said that Satoshi Action Fund co-founder Dennis Porter tweeted that after a Norwegian town banned Bitcoin mining, electricity bills per household rose by $300, an increase of more than 25%. After the ban was implemented, the decline in electricity demand in the area caused the remaining users to bear higher electricity costs to make up for the loss of income caused by the withdrawal of mining companies. Users pay not only for electricity, but also for the use of power infrastructure. This change has raised concerns about the cost sharing of power infrastructure.
