When it comes to electricity generation, South Carolina's top fuel is Nuclear, accounting for 54,926,627 megawatt hours, or 53.48% of production in the state. Natural Gas and Coal are the second and third most often used fuel types for electricity generation. Natural Gas makes up 22,465,012.53 megawatt hours (21.87%) of electricity production and Coal makes up 18,401,044.49 megawatt hours (17.92%) of total generation in the state. Approximately 23,822,664,668.91 kilograms of CO2 emissions are released in the state from electricity use. Averaging 4,509.62 kilograms of CO2 emissions per citizen, the state ranks 24th highest for emissions per capita. South Carolina has 46 power plants, which is the 21st most in the US and 33rd most when counting facilities per citizen.

Roughly 75.00% of the electricity providers in South Carolina offer net metering to their consumers. South Carolina has good regulations in place for consumers who are interested in taking advantage of net metering with solar panels.

South Carolina has 25 electricity providers who report energy loss during transmission activities. The average energy loss for these suppliers is 2.44%. With a nationwide average of 2.43%, South Carolina is the 16th best state in the country.

When it comes to stimulating personal solar, one of the government's easiest methods is tax and rebate related incentives. With over $2000 or 20% in tax credits for solar purchases, South Carolina has decent options for state solar tax credits. Offering no rebates for solar panel installs, the state currently is dropping the ball for its citizens who want to install private solar panels. The state of South Carolina offers no property tax exemptions to homeowners who install solar panels, making it less attractive for residents to do so. Homeowners in the state do not have access to a sales tax exemption when purchasing solar panels.

Whether a consumer is able to easily find electricity options with renewable fuel sources is at least somewhat determined by initiatives at the state level. Many states require green fuel sources to be a percentage of the fuel used for electricity production by providers in the state. These guidelines are referred to as Renewable Portfolio Standards (RPS). The state of South Carolina does not currently have any standards set up that providers have to adhere to. Furthermore, there are currently no low income solar programs to assist low income families to install solar panels.
