I wouldn't call it a misunderstanding; at most, it's an over-generalization:
"The bill would require all utilities serving Wyoming by 2019 to obtain their electricity from sources other than commercial-scale wind or solar operations. Utilities would be fined $10 per renewable energy megawatt hour used in a year, the amount of energy it takes to power 82 Wyoming homes."
There's an awkward unit to use--dollar per megawatt-hour per year?
Perhaps it would be clearer to say $0.01 per kilowatt-hour, though it is unclear whether the fine is levied annually, or only for energy used over a duration of one specific year.
That bit about powering 82 homes just does not compute. Homes are powered with watts. American homes average 1.25 kW. One MW powers 800 homes. One MW-h spread out over the span of one year (8760 h) is 114 W, which is enough to power about 9% of one home. So if your Wyoming home uses 9% grid-tied renewables for its power, you would probably pay $10 extra per year for this fine.
