What You'll Learn
Solar energy reduces air pollution by lowering emissions
Solar energy achieves this reduction in emissions by harnessing the power of the sun through photovoltaic (PV) panels or solar thermal systems. PV panels, commonly installed on rooftops or in solar farms, capture sunlight and convert it into electricity using semiconductor materials. Solar thermal systems, on the other hand, concentrate sunlight using mirrors or lenses to heat a fluid that generates steam to drive a turbine and produce electricity.
The use of solar energy reduces the combustion of fossil fuels like coal, oil, and natural gas, which are major sources of air pollution. This shift not only curtails greenhouse gas emissions but also diminishes the release of harmful pollutants that degrade air quality. Solar energy systems have minimal environmental impact during their operation, producing no noise or air pollution, making them pivotal in the transition to a cleaner and more sustainable energy future.
In addition to reducing emissions, solar energy installations, particularly rooftop solar panels, can have immediate positive effects on local air quality. Urban areas, which often suffer from high levels of air pollution due to dense populations and traffic, can significantly benefit from localized solar energy systems. These installations reduce the need for fossil fuel-based power plants, which are often located near urban centers, thereby lowering urban air pollution levels.
Furthermore, as solar energy becomes more prevalent, reliance on coal and natural gas power plants decreases. These power plants are among the largest sources of air pollutants. By reducing the need for their operation, solar energy indirectly contributes to a substantial decrease in air pollution.
Solar energy, with its ability to reduce emissions and lower air pollution, is a crucial component in the global effort to create a sustainable future and improve public health.

It helps to conserve water
Solar power helps to conserve water in several ways. Firstly, solar panels do not require water to generate electricity, unlike traditional power plants that use water for cooling. This distinction makes solar panels a more sustainable option, as power plants can use more than 10,000 gallons of water per megawatt of electricity generated.
The only time solar panels use water is during manufacturing and maintenance, and even then, the water requirements are generally much lower than those of conventional power generation methods. For example, solar panels do not require water for cooling, unlike nuclear power plants, which use 600-800 gallons per megawatt-hour of energy generated.
Solar panels also conserve water by reducing the need for water extraction from natural sources. Power plants typically extract water from rivers, lakes, and groundwater sources for cooling, which can negatively impact aquatic ecosystems and biodiversity.
Additionally, solar power can help minimize evaporation with floating photovoltaics (FPV) or floating solar installations. These installations float on large bodies of water, such as reservoirs, lakes, or the ocean, and provide the dual benefit of generating clean power and reducing evaporation.
Furthermore, solar power can indirectly contribute to water conservation by reducing the need for water-intensive processes such as fracking and mining for fossil fuels. By utilizing solar energy, we can move towards a more sustainable and water-efficient future.
