Fuel mix definitions
Cod generation uses coal as the primary fuel source.
Natural gas generation uses natural gas as the primary
fuel source.
Hydroelectric generation is created when water flows
from a higher elevation to a lower elevation, and the flow
is converted to electricity.
Wind generation is created by movement of air.
Biomass generation is from burning solid organic fuels
from wood, forest or field residue, or dedicated
energy crops.
Geothermal generation comes from thermal energy
naturally produced within the earti.
Solar generation uses the heat from the sun.
