Power Plant Fuel Types, Emissions & Pollution Factors

In Delaware, Natural Gas makes up 82.49% of the fuel sources utilized for electricity generation. Coal and Other Gas are also important fuel sources in the state, with 7.26% and 3.98% of total electricity generation being generated from each, respectively. The state is the 45th worst ranked state when it comes to total CO2 pollution, with the state consuming enough electricity to account for 4,567,353,279.75 kilograms of CO2 emissions. More telling of the state's emissions reality is the per resident CO2 totals. Currently that amount stands at 4,484.85 kilograms of CO2 emissions from electricity use, which results in the state ranking as the 25th highest state in the US for CO2 pollution released per capita. Delaware has the 49th highest amount of electricity generation plants of any state in the United States, with 10 plants. This translates to the 29th most plants per person in the United States.

Delaware Net Metering

Delaware has 12 out of 28 electricity providers reporting that they offer net metering to residents with personal solar panels. At the state level, Delaware has favorable regulations for consumers interested in investing in solar.

Energy Loss

There are 6 electricity providers in Delaware that reported energy loss. Together, these 6 providers average a yearly energy loss of 3.94% of electricity generated. The countrywide average is 2.43%, resulting in Delaware receiving a rank of 37th best in the US for energy loss efficiency.

Solar Taxes And Rebates

State governments can help encourage private citizens to consider installing solar panels by promoting tax incentives and rebates to their populace. Delaware currently does not offer a state tax credit for solar panel installation at a private residence. Customers are able to apply for rebates of $500 or less for private solar purchases. Delaware offers no property tax exemptions to homeowners who purchase solar panels. There is currently a 100% sales tax exemption in place for the purchase of private solar panels at a place of residence.

State Level Initiatives

Consumers who are shopping for electricity plans that use renewable sources will have much better luck if there are state level initiatives that encourage green energy usage. Many states require renewable fuels to make up a percentage of the fuel used for electricity generation by electricity companies in the state. These requirements are referred to as Renewable Portfolio Standards (RPS). While further improvements could be made, Delaware makes it necessary for 1-15% of electricity generation to come from renewable fuel sources. In addition, the state does not have any sort of low income solar programs that assist with the installation of solar panels at low income households.
