How Much Would a CO2 Tax Raise Gasoline and Electricity Price

It looks from this article like a $100/ton CO2 tax would raise a gallon of gasoline by $.80 and raise electricity cost by about 36%. Seems to me that this should not be such a big deal and I think at $100/ton it might be enough to remove CO2 from the air.

People would not end up paying that much as electric Companies would produce more not CO2 producing methods and Petroleum prices would be lower than they'd otherwise be and people would tend to buy vehicles that get higher mileage.
