Iowa Nuclear Profile 2010 Iowa profile

Iowa total electric power industry, summer capacity and net generation, by energy
source, 2010
Primary energy source	Summer capacity (mw)	Share of State total (percent)	Net generation (thousand mwh)	Share of State total (percent)
Nuclear	601	4.1	4,451	7.7
Coal	6,956	47.7	41,283	71.8
Hydro and Pumped Storage	144	1.0	948	1.6
Natural Gas	2,299	15.8	1,312	2.3
Other Renewable¹	3,584	24.6	9,360	16.3
Petroleum	1,007	6.9	154	.0.3
Total	14,592	100.0	57,509	100
¹Municipal Solid Waste net generation is allocated according to the biogenic and non-biogenic components of the fuel; however, all Municipal Solid Waste summer capacity is classified as Renewable. Notes: Totals may not equal sum of components due to independent rounding. Other Renewable: Wood, black liquor, other wood waste, biogenic municipal solid waste, landfill gas, sludge waste, agriculture byproducts, other biomass, geothermal, solar thermal, photovoltaic energy, and wind.
