Solar energy is extremely abundant, widely distributed and easy to apply, and photovoltaic power generation using solar energy has significant energy, environmental and economic benefits. So how can solar energy and photovoltaics help us improve the environment? In the following section, we will explore the power of solar energy and photovoltaics.
Reducing Air Pollution
Air pollution is another major environmental challenge caused by fossil fuel combustion. The use of fossil fuels for transportation, power generation and heating is essential to our day, but this leads to increased levels of air pollutants such as particulate matter, nitrogen oxides and sulfur dioxide. These pollutants can have harmful effects on human health, including respiratory and cardiovascular disease.
Photovoltaics, on the other hand, can reduce our dependence on fossil fuels by using clean and sustainable solar energy, which over time will reduce air pollution. The electricity generated by solar systems can be used to generate electricity, heating and cooling, and depending on the amount of power installed, can meet all the electricity needs of the average home as well as the needs of a factory.

Improving Climate Change
Climate change is one of the most significant environmental challenges facing the world today, which can lead to a series of impacts such as warming and rising sea levels, which in turn can lead to reduced food production and health hazards. It is caused by the accumulation of greenhouse gases in the atmosphere, mainly carbon dioxide (CO2). Unlike fossil fuels, solar and photovoltaic systems do not emit any harmful pollutants when generating electricity; they use clean, sustainable and renewable solar energy to reduce CO2 emissions.
Carbon Footprint is the "carbon consumption" of a person or group, i.e. the total amount of greenhouse gases emitted during production, use and disposal. The more "carbon" is consumed, the more "carbon dioxide" is produced, and the more "carbon footprint" is created. The larger the "carbon footprint", the smaller the "carbon footprint". Compared to fossil fuels, solar PV has a relatively low carbon footprint. The production of solar panels and other components of a PV system requires energy, but this is offset by the reduction in emissions over the life cycle of the PV.
The carbon footprint of solar PV can be further reduced by using recycled materials in production.
