The carbon footprint of PV solar systems' was estimated in the range (14–73 g CO 2 -eq/kWh), which is lower than gas (607.6 CO 2 -eq/kWh) oil (742.1 CO 2 -eq/kWh), and coal-fired (975.3 g CO 2 -eq/kWh) power plants. Up to 50% lower GHG emissions can be achieved using new materials and/or recycled silicon material.

Photovoltaic (PV) systems are regarded as clean and sustainable sources of energy. Although the operation of PV systems exhibits minimal pollution during their lifetime, the probable environmental impacts of such systems from manufacturing until disposal cannot be ignored. The production of hazardous contaminates, water resources pollution, and emissions
GDP and nonrenewable energy use, however, have a favorable impact on CO2 emissions in Nigeria (Agboola, 2018). On the contrary, nonrenewable energy usage has a beneficial effect on Angola''s GDP. Furthermore, the impact of harmful greenhouse gas emissions and petroleum usage changes is the same as that of positive changes in Nigeria and Egypt.
By comparison, according to the EPA, the average acre of forest in the United States sequesters 0.84 metric tons of carbon dioxide per year. Thus, an acre of solar panels installed to replace natural gas reduces approximately 208 to 236 times more carbon dioxide per year than an acre of forest.
Photovoltaic development has played a crucial role in mitigating the energy crisis and addressing global climate change. However, it has also had significant impacts on the ecological environment.
LCA studies show that, on average, more than 80% of the environmental impact of solar PV is due to the production process of the included modules. Most works [ 30 - 33 ] focus on the manufacturing of different crystalline modules and explain the impacts of this stage, while other studies evaluate the life cycle impacts of rooftop PV systems
Plastics are essential materials for modern societies, but their production contributes to significant environmental issues. Power-to-X processes could produce plastics from captured CO 2 and hydrogen with renewable electricity, but these technologies may also face challenges from environmental perspective.
