C02 emissions to produce small solar panels.

By scott cramer although the use of solar panels is green many solar panel manufacturing processes are not. The team found that for every doubling of the world s solar capacity the energy required to make a panel fell by around 12 and associated carbon dioxide emissions by 17 24. 0 0053 metric tons co 2 therm x 10 37 therms mcf 0 0549 metric tons co 2 mcf. This equaled about 0 99 pounds of co2 emissions per kwh.

In general it has been estimated that around six months are needed for a solar panel to produce the energy required to clear the carbon dioxide emitted to produce it. In fact half of the world production of photovoltaic panels takes place in china. The researchers gathered air pollution emissions data from 13 manufacturers of four major commercial types of solar cells in europe and the united states from 2004 to 2006. For example increasingly less energy will be required to produce solar modules due to technological progress and a shift towards less energy intensive technology variants.

Solar panel manufacturers need electricity and thermal energy and carbon emissions from their generation can vary widely. For instance concentrated solar power csp has a footprint of 20 grams of carbon dioxide co2 per kilowatt hour kwh of electricity produced in addition to consuming vast amounts of. Carbon dioxide emissions per therm can be converted to carbon dioxide emissions per thousand cubic feet mcf using the average heat content of natural gas in 2017 10 37 therms mcf eia 2019. At the same time the global climate change mitigation effort will reduce the co2 emissions per unit of electricity and steel inputs further limiting life cycle greenhouse.

However this aspect depends mostly on the place of production. To create a solar panel caustic materials will emit greenhouse gases. Argonne national laboratory fengqi you et al. Electricity generation by the electric power industry of 4 17 trillion kilowatthours kwh from all energy sources resulted in the emission of 1 87 billion metric tons 2 06 billion short tons of carbon dioxide co2.

How do solar panels reduce your carbon emissions.
