• Primary energy for combustible fuels (petroleum, natural gas, coal, biomass, biogas) is defined as the higher heating value of the fuel prior to combustion, whereas primary energy for non-combustible fuels (hydroelectric, nuclear, geothermal, solar, wind) is defined as the heat content of net electricity generated.

• Throughout the focus regions, electricity producers rely on energy from a range of primary fuels including nuclear, coal, natural gas, oil water, wind, solar, geothermal, and others.

• In countries where generation systems are based in plants with low emission of greenhouse gases (prevalence of hydro, wind, nuclear, etc), the electrification is an effective way to mitigate the global warming.
