PV carbon emissions 2015 global average of 20 g kWh

Polaris solar PV net news: there is no doubt that PV power generation without carbon emissions. PV module production process requires energy, so PV has carbon emissions. Netherlands UtrechtUniversity scholar Dr WilfriedvanSark 1975-2015 is calculated by global production of photovoltaic modules between energy consumption and carbon emissions, the report published in the journal NatureCommunications. Of course, PV module production process of carbon emissions depends on the photovoltaic production time and place. As China’s energy structure dominated by coal, PV module production in China’s high carbon emissions the European production of PV modules 1 time. But as technology advances and changes in the energy mix, declining emissions of PV module production.


PV carbon emissions: 2015 global average of 20 g/kWh

In considering a PV module production circumstances of time and place, Dr WilfriedvanSark’s team calculated 1975 global PV modules within the full life-cycle (say 30) average 400-500 grams of carbon emissions per kilowatt hour in 2015 and PV modules within the life cycle of the global average of only 20 grams of carbon emissions per kilowatt hour. 1975 each PV module take 20 years of run time to recovery of the energy consumed by the PV modules, 2015 solar components energy payback period of less than 2 years. In General, whenever the global PV installed capacity doubled, PV module power consumption dropped production by some 12%, 17-24% reduction in carbon emissions.
