6. Connecticut
> Emission-free power from nuclear: 97%
> Number of nuclear power plants: 1
> Electricity generated by nuclear: 50%
> Energy price per capita: 18.5 cents (2nd highest)
> Population: 3.6 million
> Density Rank: 4th

Only Hawaii has higher residential electricity rates than Connecticut. The Millstone nuclear power station in Waterford produces half of the state’s electric power.

7. Ohio
> Emission-free power from nuclear: 97
> Number of nuclear power plants: 2
> Electricity generated by nuclear: 11%
> Energy price per capita: 11.7 cents (20th highest)
> Population: 11.5 million
> Density Rank: 10th

Coal is king when generating electricity in Ohio. However, nuclear energy accounts for nearly all of its emission-free power. The rest comes from solar and wind energy.

8. South Carolina
> Emission-free power from nuclear: 97%
> Number of nuclear power plants: 4
> Electricity generated by nuclear: 50%
> Energy price per capita: 11.5 cents (22nd highest)
> Population: 4.7 million
> Density Rank: 19th

In a state where electricity use per capita is high, half of the demand is produced by its four nuclear plants.

9. Illinois
> Emission-free power from nuclear: 95%
> Number of nuclear power plants: 6
> Electricity generated by nuclear: 48%
> Energy price per capita: 12.4 cents (17th highest)
> Population: 12.9 million
> Density Rank: 12th

About one tenth of the total nuclear-powered electricity generation in the United States comes from Illinois.

10. Pennsylvania
> Emission-free power from nuclear: 95%
> Number of nuclear power plants: 5
> Electricity generated by nuclear: 34%
> Energy price per capita: 13.6 cents (12th highest)
> Population: 12.7 million
> Density Rank: 9th

In addition to being a major coal producing state, Pennsylvania also ranks second in the nation in nuclear power generating capacity.
