    Above a certain price the energy expenses outweight the wealth that its use can produce. When that happens people will be better off staying at home and doing nothing than trying to be productive. The questions asks what do you think that price is, given the information provided.

    Isn't the highest possible price 0,4$/kWh
    0,4$/kWh = O,29€/kWh?
