Kentucky coal keeps Kentucky electricity cheap

Cheaper than elsewhere anyway. Read the piece in the Tennessean here. The coal doesn't have to be shipped very far. Next month, when rate increases kick in, Tennesseans, reliant on TVA, will pay about 25% more than those in Kentucky who get their power from two private utilities. 62, 28, and 10...

TVA's power sources are 62 percent coal. The largest chunk is mined in
Kentucky, followed by Illinois, Utah and then Colorado. Another 28 percent comes
from nuclear power, which has relatively low fuel costs. About 10
percent is
generated at hydroelectric dams, though drought has cut into
this.

95 and 5, those are the numbers for Kentucky...

To Tennessee's north, Louisville Gas and Electric Company and Kentucky Utilities
Company are owned by the German company E.ON and serve about 1.2 million
customers.
The mix of sources is 95 percent coal, some natural gas and a

Nationally, about 50% of electricity is generated by coal-fired plants and 20% comes from natural gas. Some comparisons in cost from the article...

TVA distributor charges for residential electric service will run about
$106 for 1,000 kilowatt hours as of Oct. 1. The two major Kentucky utilities
will be charging about $80 for that same amount, according to TVA
information.
Residents served by two large Texas utilities that have relied
heavily on natural gas will pay more than double what Kentucky residents
pay.
In California's Sacramento Municipal Utility District, residents will
pay $110, just $4 more than TVA customers, for 1,000 kilowatt hours, according
to SMUD information. Almost half comes from hydroelectric, solar and other
renewable resources, with the rest largely from natural gas.
