Delaware's Electricity Fuel Mix shows rising natural gas and renewables
The most recent data published by Delmarva Power and PJM Interconnection shows the historic transition of our fuel supply for electricity in Delaware.
The fuel resource mix data for the state of Delaware's electricity supply shows the proportion of coal used to supply electricity has fallen from 57.4% in 2001 to 46.5% in 2011.
Electricity supplied from oil also declined, from 3.2% in 2001 to 0.4% in 2001. While the proportion of oil and coal used to supply electricity fell during this 11-year period, other fuels increased: natural gas rose from 5.7% in 2001 to 13.6% in 2011; nuclear energy increased from 27.5% in 2001 to 34.2% in 2011; and renewables increased from 3.2% in 2001 to 5.3% in 2011.
In the renewables sector, hydroelectric generation, solid waste and wood or other biomass has declined. Captured methane gas and wind power have increased. In 2011 solar applications were generating power within Delaware, but the quantity, as reported by Delmarva and PJM Interconnection, was les than 0.1% through 2011 (and therefore does not appear on this graph).
