Let say carbon tax of $200/ton, or 20c/kg. US co2 generation on the grid is about 0.5kg per kwH, so would add 10c/kWh. That means that your PS5, using 200 Watts, costs an extra 2c per hour to play -- on top of the existing 15c/hr for normal electric costs. A single bitcoin transaction of 780kWh would cost $78 and a transatlantic flight about $300, or $1.20 to a gallon of gas. Make the tax $2k/ton, it raises your PS5 cost from 15c/hr to 25c/hr and a bitcoin transaction to $780 and take transatlantic flights back to the cost of the 70s That sounds fine to me. The energy used by a PS5 is insignificant. > You see how this reasonning can go? Yes I do, it sounds really exciting. The money raised would be spent on carbon reduction (which gives a financial incentive to Brazil to not chop down rainforest, or pays for other forms of carbon capture), and disincentivises carbon usage. Brilliant.
