Our Energy System

Our Energy System "This interactive diagram is based on the energy flow diagram produced by Lawrence Livermore National Laboratory in 2009. The data are from the Energy Information Administration of the U.S. Department of Energy (DOE/EIA-0384(2008), June 2009). Hydro, wind, and solar electricity inputs are expressed using fossil-fuel plants’ heat rate to more easily account for differences between the conversion efficiency of renewables and the fuel utilization for combustion- and nuclear-driven systems."
