In this article, we will delve into the world of solar energy and examine the environmental impact of using this greener energy source,
Collecting the sun’s energy and converting it to create electricity for domestic and commercial use can significantly reduce carbon emissions and help combat climate change. Before we look at the potential environmental impacts of solar energy, let’s better understand how sunlight turns into electricity.
Sunlight is a clean energy source that converts into electrical energy through photovoltaic or solar panels. The sun releases packets of energy called photons. Photons are constantly emitted on our planet, generating enough solar energy to satisfy energy needs for an entire year around the world.
A solar panel consists of many solar cells. These solar cells made of silicon act as semiconductors. They are made with a positive and negative layer with other materials like phosphorus and boron to create an electric field. When sunlight hits solar cells, photons or particles of light eliminate free electrons, generating electricity.
Does Solar Power Impact The Environment?
From an energy production point of view, most electricity comes from fossil fuels such as oil and coal. In 2020, fossil fuels represented 79%9 of total energy consumption in the United States6.
Energy derived from fossil fuels comes from the Earth’s natural, finite resources. To generate energy, manufacturers extract fossil fuels from the ground using methods such as drilling, hydraulic fracturing and mining.
Unfortunately, these processes have a detrimental effect on the surrounding environment. For one, it exposes our water systems to hazardous materials and weakens the soil, making it prone to natural disasters like earthquakes and floods.
Other issues arise when obtaining oil offshore or in the ocean. Manufacturers drill into the seabed, which disrupts marine life and increases the risk of an oil spill.
What Is Passive And Active Solar Energy?
As tankers or pipelines transport oil across seas and lands, accidental oil leaks and spills can occur, harming our environment.
Energy companies and utilities burn fossil fuels to produce electricity, which releases toxic gases into the atmosphere. This contributes to the emission of enormous amounts of greenhouse gases, such as carbon dioxide, which ultimately leads to environmental crises such as global warming and climate change.
Due to the harmful effects of fossil fuels on the environment, many countries are switching to renewable energy sources such as solar energy.
Fossil fuels like natural gas, coal and oil are finite resources that cannot be replaced once they are burned. Solar panels use photons from the sun to capture enough energy to effectively and perpetually produce electricity as long as the sun shines. This is great because solar energy is a renewable source that replenishes itself naturally and constantly, without running out. Here are some environmental benefits of solar energy:
Off Grid Solar Pros And Cons
By burning fossil fuels such as natural gas, coal and oil, billions of tons of carbon dioxide and other harmful gases are released into the air.
In the United States, the burning of fossil fuels was responsible for 73% of greenhouse gas emissions in 20207. The emission of these gases contributes to atmospheric pollution and intensifies environmental issues such as climate change and global warming.
Several studies have been carried out over the years to measure carbon emissions from solar energy and other energy sources. Carbon emission intensity for solar panels and other fuels can be expressed in grams of carbon dioxide equivalent per kilowatt-hour (gCO2/Kwh) or tonnes of carbon dioxide equivalent per megawatt-hour (tCO2/Mwh). Lower carbon emission intensity means more positive environmental impacts.
According to studies by the US Department of Energy’s National Renewable Energy Laboratory in 2014, the life cycle carbon emission intensity of solar energy was measured at approximately 40gCO2 per kilowatt-hour, while that of coal fell at approximately 1000gCO2 per kilowatt-hour. In simpler terms, coal produces 25 times more carbon dioxide than solar energy to create the same amount of energy2.
What Are The Health Risks Living Near Solar Farm?
The sun is the main source of energy for solar panels. With solar energy, we can reduce the effect of burning fossil fuels and reduce emissions from energy production.
Water is one of the most essential natural resources on our planet. Furthermore, drinking water has become a scarce commodity.
For conventional electricity, water is an essential part of the manufacturing process. From extraction to transportation and power generation, manufacturers use liters of water to produce energy. Although the water used in power plants is returned, some evaporates or becomes contaminated.
With solar energy, water conservation is possible. Solar panels need little or no water to produce electricity. This prevents dangerous chemicals and gases from polluting our water sources. It also preserves clean water.
The Advantages & Disadvantages Of Solar Energy
The quality of the air we breathe can significantly impact human health and the environment. Electricity from burning fossil fuels generates carbon dioxide and other harmful gases such as methane, which causes air pollution and reduces air quality.
Additionally, these harmful chemicals and gases contribute to acid rain, which disrupts our entire ecosystem, lowering the pH of water systems and killing aquatic life. Acid rain also poisons the soil and kills nutrients essential for plant growth. Furthermore, these gases contribute significantly to chronic respiratory diseases.
As we move to generating electricity from solar panels, we can reduce the need for power plants that release dangerous air pollutants.
We have a finite amount of natural resources such as oil, natural gas and coal. With energy generated from burning fossil fuels, we run the risk of running out of these resources.
Advantages & Disadvantages Of Solar Energy
Solar energy produces electricity in a more sustainable way. It takes advantage of a free renewable energy source, sunlight, reducing energy prices, reducing carbon emissions and relying less on finite fossil fuels.
One of the significant effects of burning fossil fuels is climate change and global warming. Solar is a renewable energy source free of dangerous carbon emissions.
Solar energy can create cleaner energy and protect the environment from climate change. According to the US solar industry, solar energy has significantly reduced global warming emissions, to the equivalent of planting 2 billion trees.
Solar panels create clean energy, free from carbon emissions that affect the environment. However, as with most things in life, solar energy is not perfect. Using solar panels to generate electricity also has environmental disadvantages.
The Pros And Cons Of Using Solar Energy
The amount of chemicals used for cleaning largely depends on the size of the solar panels and the cleaning required. These chemicals include hydrofluoric acid, sulfuric acid, hydrogen fluoride, etc.
In addition to releasing these chemicals into the atmosphere, solar panel manufacturers run the risk of inhaling silicon dust, threatening public health.
However, there are government guidelines that solar companies need to follow to ensure proper handling and disposal of these chemicals.
Solar panels require high energy consumption to be produced. Mining, manufacturing and transportation require a substantial amount of energy initially and throughout the development of solar energy. For example, processing quartz into silicon requires other materials such as aluminum and copper. The heating process also requires high heat.
Solar Roadways: An Engineering Failure Of Epic Proportions
For these processes to work at scale, manufacturers need to use a lot of energy from traditional fuels like gas, coal and other fossil fuels, which release harmful greenhouse gases and increase the carbon footprint of solar cells.
For solar companies to establish large-scale solar power systems, they require a large tract of land, from which they typically clear everything, including vegetation. Ultimately, this could lead to the loss of wildlife habitats.
Water resources diverted to solar projects can also harm wildlife. Additionally, the construction of solar installations can result in soil compaction and erosion. One way to reduce wildlife habitat loss is to build solar panel systems on existing infrastructure such as parking lots, commercial buildings, brownfields, etc.
As we mentioned previously, installing a solar plant requires a large area of land, which is completely deforested, leading to soil erosion. Additionally, improper disposal of chemicals used during manufacturing can cause water, air, and soil pollution. The manufacturing, installation and transportation of solar panels also contribute significantly to carbon emissions.
Disadvantages Of Solar Energy To Consider Before You Install
One way to reduce emissions is to replace fossil fuels like coal during production processes with more sustainable options like renewable biomass.
Solar is clean energy that undeniably plays a significant role in saving the planet. However, solar panel manufacturing processes may involve more environmental sacrifices than we think. How do companies make solar panels? What are the environmental impacts involved?
Solar panels consist of solar cells, a frame, a backsheet, conductors, a tempered glass cover and other materials. Most of the raw materials used need to be extracted and processed.
For example, manufacturers process quartz into silicon. Materials such as copper, aluminum and copper are also mined. The manufacturing process also involves heating and treating various chemicals, which can be dangerous to humans and the environment.
