Carbon Dioxide

Carbon Dioxide (CO₂), a colorless and odorless gas, plays a central role in climate discussions. As the main greenhouse gas, it is a key contributor to human-caused climate change. In the context of energy generation, and especially photovoltaics (PV), CO₂ also offers avenues for solutions.

CO₂ Emissions in PV Manufacturing

Although solar power does not produce direct CO₂ emissions during operation, greenhouse gases are emitted during the manufacturing of solar panels. These emissions are mainly due to the energy required for producing the necessary materials and components. However, the CO₂ balance of PV production has significantly improved in recent years due to technological advancements and a more sustainable energy supply for production facilities.

CO₂ Reduction through Photovoltaics

The greatest strength of photovoltaics lies in its ability to avoid CO₂ emissions. By utilizing solar energy as a nearly inexhaustible and emission-free energy source, PV makes a significant contribution to reducing CO₂ emissions.

  • Power Generation: Every kilowatt-hour of electricity generated by a PV system replaces an equivalent amount of electricity from fossil fuels, which release CO₂ when burned.
  • Decentralized Energy Supply: PV systems enable decentralized power generation, reducing the need for long-distance electricity transmission and minimizing associated losses.

CO₂-Negative Cycle

In combination with other technologies, photovoltaics can even contribute to a negative CO₂ balance. For instance, hydrogen produced with solar power can be used to capture CO₂ from the atmosphere and convert it into synthetic fuels.

Conclusion

Carbon dioxide and photovoltaics are closely linked. While PV production leaves a certain CO₂ footprint, the positive effect of CO₂ savings through electricity generation far outweighs it. Through continuous technological advancement and the use of solar power to decarbonize other sectors, photovoltaics is becoming an increasingly important component in the fight against climate change.
