    Seems like the 2,601GWh was replaced by
    1,058GWh Gas
    0,662Gwh Imports.
    0,078GWh Rooftop PV
    0,062GWh Diesel and small non-scheduled generation
    0,021GWh Wind

    What should they have replaced the coal with instead?

    I have seen many times the connector run the other way. Exporting power to Vic from SA.

    The coal was shutdown due to it not being able to make money.

    If it is a solar sail then you get to make it orbit the sun and accelerate and decelerate to keep it in-between the sun and the earth.

    And what happens if you get less miners? Well the difficultly drops so it requires less electricity to mine there by making it profitable again to mine..

    Fees by themselves are there to allow miners to make a bit extra.. The miners will pick the transactions with the highest fees first and include in the blocks, so if there are loads of unconfirmed transactions people will choose to pay a higher fee to have their transactions complete faster. But even then, when we had the issue with loads of unconfirmed transactions i still could make payments with low fees, but they took forever before being included (confirmed) in a block.

    If you look far into the future, when all payable blocks have been mined, it will only be transaction-fees that will pay for the miners.

    If bitcoin will survive i think we will have bitcoin-miners in everything where we have a need to generate heat from electricity. Why push electricity thru a resistor to generate heat when we can have a

      CPU/ASIC/FPGA/whatever using the same amount of electricity to do bitcoin-calculations and still generate the same amount of heat, with the benefit of collecting some transaction-fees. Of course the miners will have to drop down quite a bit in price for that to happen.

    Or you use a heat pump and get more heat for the same amount of electricity.
