The use of solar energy has a significant positive impact on reducing greenhouse gas emissions and air pollution compared to traditional fossil fuels in the production of electricity. This is because solar energy is a clean and renewable source of energy, whereas fossil fuels are non-renewable and release harmful pollutants when burned.1. Greenhouse gas emissions: The primary greenhouse gas emitted by burning fossil fuels is carbon dioxide CO2 . Other greenhouse gases, such as methane CH4 and nitrous oxide N2O , are also released during the extraction, processing, and transportation of fossil fuels. Solar energy, on the other hand, produces electricity through photovoltaic PV panels or solar thermal systems, which do not emit greenhouse gases during operation. While there are some emissions associated with the manufacturing, transportation, and installation of solar panels, these are significantly lower than those associated with fossil fuels.2. Air pollution: Burning fossil fuels releases various air pollutants, including particulate matter PM , sulfur dioxide SO2 , nitrogen oxides NOx , and volatile organic compounds VOCs . These pollutants can cause respiratory problems, heart disease, and other health issues in humans, as well as contribute to smog and acid rain. Solar energy systems do not produce these harmful pollutants during operation. As mentioned earlier, there may be some emissions during the manufacturing and transportation of solar panels, but these are minimal compared to the pollution generated by fossil fuels.In conclusion, the use of solar energy for electricity production significantly reduces greenhouse gas emissions and air pollution compared to traditional fossil fuels. This makes solar energy a more environmentally friendly and sustainable option for meeting our energy needs.
