Specific Emission Balance

Table 9.2 shows the commutated energy expense (divided in electricity, fuels, and non-energy consumption) and the CO2-emission of a PV-power plant in Germany. The CO2-balance in Table 9.2 was based on the sectors of energy expenses; for electricity the actual power plant composition was applied.
