The U.S. Energy Information Agency has an easy way to find out the energy profiles of the Carolinas. Interesting to see it laid out for a fast reference. Note, though, that while these figures were released in August, 2017, they reflect 2015 numbers. Still, a good reference point.

South Carolina’s energy profile is here. Some of the SC commentary from the EIA:

  • Ranked third in the nation in nuclear generating capacity and annual generation, South Carolina produces almost three-fifths of its net electricity generation from nuclear power.
  • The contribution from natural gas-fired power plants has almost tripled
    Hydropower and biomass … South Carolina’s primary renewable resources.
  • South Carolina generates more electricity than it consumes and sends its surplus to other states.

 

North Carolina’s energy profile is here. Some of the NC commentary from the EIA:

  • North Carolina is one of the nation’s top producers of electricity from nuclear power.
  • North Carolina does not have any natural gas reserves or production. Natural gas supplied about three-tenths of the state’s net generation in 2016, exceeding coal’s contribution for the first time.
  • The largest share of retail electricity sales in the state goes to the residential sector.
  • Hydroelectric dams provide about two-fifths of the electricity generated from renewable resources in North Carolina.

Just recently, on March 20, 2018, the EIA released 2017 nationwide figures about electric generation. The report says (selected comments):

According to EIA’s Electric Power Monthly, total U.S. net electricity generation fell slightly (down 1.5%) in 2017, reflecting lower electricity demand. Natural gas and coal generation fell by 7.7% and 2.5% from 2016, respectively, as generation from several renewable fuels, particularly hydro, wind, and solar, increased from 2016 levels.

Although natural gas continued to be most-used fuel for electricity generation for the third consecutive year, natural gas-fired electricity generation fell by 105 billion kilowatt-hours in 2017, the largest annual decline on record. Coal-fired electricity generation also fell, but to a lesser extent, marking the first year since 2008 that both natural gas- and coal-fired electricity generation fell in the same year.

Electricity from renewable sources, especially wind and solar, continued to increase in 2017. Wind made up 6.3% of total net generation, and utility-scale solar made up 1.3%—record shares for both fuels.
