Recently, due to the growing energy crisis and extremely expensive electricity in Pakistan, especially in Karachi, solar systems are rapidly becoming popular as an alternative to traditional power plants. However, there is little understanding of whether this alternative is truly environmentally friendly.
Generally, it can be said that during the production of electricity in traditional power plants, harmful gases such as carbon dioxide, sulfur dioxide, and nitrogen oxides, which significantly contribute to global warming, are emitted. Solar systems play an important role in reducing the emission of these harmful gases.
Additionally, they eliminate the need for fuel, benefiting both human populations and ecosystems. They improve air quality and conserve water resources. In short, solar systems emerge as an excellent alternative to promote environmental benefits and reduce climate change while fostering environmental sustainability. However, it is also important to acknowledge their potential drawbacks and negative impacts on the environment.
First and foremost, it is essential to mention the manufacturing of solar panels. Extracting and processing raw materials used in solar panels, such as silicon, cadmium, and gallium, can cause environmental degradation. Mining activities, especially in regions with weak environmental regulations, like Pakistan, can lead to habitat destruction, soil erosion, water pollution, and loss of biodiversity.
Experts state that the operational life of solar panels is about 20 years, after which they are no longer efficient. As a result, solar system users will face several challenges in the future related to disposing of them as scrap, leading to a new form of environmental pollution.
On the other hand, considering Pakistan’s changing climate and the intense heat in Karachi, local experts say that solar plates used in solar systems possess a specific gravitational or magnetic force that attracts sunlight. In simpler terms, the larger the solar plate, the greater its gravitational force, which undoubtedly increases energy production. However, this also raises concerns about increased solar heat.
As we move towards environmentally friendly energy production methods, it is crucial to recognize the interconnection of environmental, social, and economic factors in shaping our energy systems. We must develop comprehensive policies for managing solar panels and fully harness the potential of solar energy. Otherwise, we may face a new and dangerous form of environmental pollution.
