In this article, we dive into the world of solar energy and examine the environmental impact of using this renewable energy source.

By collecting solar energy and converting it into electricity for your home or business, you can significantly reduce your carbon footprint and help fight climate change. Before examining the potential impact of solar energy on the environment, let’s better understand how sunlight is turned into electricity.

Sunlight is a clean energy source that is converted into electrical energy through photovoltaics or solar panels. The sun emits packets of energy called photons. Photons are constantly being emitted on Earth, generating enough solar power to meet the world’s energy needs for a year.

A solar panel consists of a large number of solar cells. Made of silicon, these solar cells act as semiconductors. These are made of positive and negative layers containing other materials such as phosphorus and boron to generate an electric field. When sunlight hits a solar cell, photons, or particles of light, knock off free electrons, creating electricity.

Solar Power Advantages And Disadvantages

From a power generation perspective, most electricity comes from fossil fuels such as oil and coal. In 2020, fossil fuels accounted for 79%9 of total US energy consumption6.

Energy derived from fossil fuels comes from the earth’s finite natural resources. To generate energy, manufacturers extract fossil fuels from the ground using methods such as drilling, hydraulic fracturing, and mining.

Sadly, these processes have a negative impact on the surrounding environment. For example, water systems are not only exposed to harmful substances, but the ground is also weakened, making it more susceptible to natural disasters such as earthquakes and floods.

Other issues arise when oil is sourced offshore or from the ocean. Manufacturers are drilling into the ocean floor, which disturbs marine life and increases the risk of oil spills.

What Is The Carbon Footprint Of A Solar Panel? Overview And Emissions

When offshore tankers and pipelines transport oil through the ocean or land, accidental oil leaks and spills can occur and cause environmental damage.

Power companies and utilities burn fossil fuels to create electricity, but in the process they release toxic gases into the atmosphere. This generates large amounts of greenhouse gases such as carbon dioxide, which ultimately causes environmental crises such as global warming and climate change.

Due to the negative impact of fossil fuels on the environment, many countries are switching to renewable energy sources such as solar energy.

Fossil fuels such as 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 generate electricity forever, as long as the sun shines. This is great because sunlight is a renewable energy that never runs out naturally and is constantly replenished. The environmental benefits of solar energy include:

How Can Solar Energy Be Stored For When The Sun Isn’t Shining?

The combustion of fossil fuels such as natural gas, coal, and oil releases billions of tons of carbon dioxide and other harmful gases into the atmosphere.

In the United States, fossil fuel combustion accounted for 73% of greenhouse gas emissions in 2020.7 Emissions of these gases contribute to air pollution, exacerbating environmental problems such as climate change and global warming.

Several studies have been conducted over the years to measure the carbon emissions of the sun and other energy sources. The carbon emission intensity of solar panels and other fuels can be expressed in grams of carbon dioxide equivalent per kilowatt hour (gCO2/Kwh) or tons of carbon dioxide equivalent per megawatt hour (tCO2/Mwh) . Lower carbon emission intensity means a greater positive impact on the environment.

According to a 2014 study by the U.S. Department of Energy’s National Renewable Energy Laboratory, the lifecycle carbon emission intensity of solar power was measured at about 40 gCO2 per kilowatt-hour, compared to that of coal at about 1000 gCO2 per kilowatt-hour. It has decreased. Simply put, coal produces 25 times more carbon dioxide than sunlight while producing the same amount of energy2.

Confronting The Solar Manufacturing…

The sun is the main energy source for solar panels. Harnessing sunlight can reduce the impact of fossil fuel combustion and reduce emissions from energy production.

Water is one of the most important natural resources on earth. Additionally, clean water has become a scarce commodity.

For traditional electricity, water is an essential part of the production process. From mining to transportation to power generation, manufacturers use liters of water to produce energy. The water used in power plants is returned, but some of it evaporates or becomes contaminated.

You can also save water by using solar power. Solar panels require little or no water to generate electricity. This prevents contamination of water sources with harmful chemicals and gases. You can also store clean water.

The quality of the air we breathe can have a major impact on human health and the environment. Electricity from burning fossil fuels produces other harmful gases such as carbon dioxide and methane, causing air pollution and reducing air quality.

These harmful chemicals and gases also cause acid rain, which disrupts entire ecosystems by lowering the pH of water systems and killing aquatic life. Acid rain also contaminates the soil and kills essential nutrients that plants need for proper growth. Furthermore, these gases are a major cause of chronic respiratory diseases.

Switching to solar panel power generation can reduce the need for power plants that emit dangerous air pollutants.

Natural resources such as oil, natural gas, and coal are finite. Because energy is produced by burning fossil fuels, we run the risk of depleting these resources.

Solar energy generates electricity in a more sustainable way. Harnessing sunlight, a free renewable energy source, lowers energy prices, reduces carbon emissions and reduces dependence on finite fossil fuels.

One of the significant effects of burning fossil fuels is climate change and global warming. Sunlight is a renewable energy source with no dangerous carbon emissions.

Harnessing sunlight can help us generate cleaner electricity and protect the environment from climate change. According to the U.S. solar power industry, solar energy significantly reduces global warming emissions, equivalent to planting 2 billion trees.

Solar panels produce clean energy without carbon emissions that affect the environment. But like most things in life, solar power isn’t perfect. There are also environmental downsides to using solar panels to generate electricity.

Solutions For Solar Panel Waste Are Just Beginning To Surface

The amount of chemicals used for cleaning varies greatly depending on the size of the solar panel and the cleaning required. These chemicals include hydrofluoric acid, sulfuric acid, and hydrogen fluoride.

In addition to releasing these chemicals into the atmosphere, solar panel manufacturers also inhale silicone dust, which poses a public health hazard.

However, there are government guidelines that solar companies must follow to ensure proper handling and disposal of these chemicals.

Manufacturing solar panels requires high energy inputs. The mining, manufacturing, and transportation processes require a large amount of energy up front. For example, processing quartz into silicon requires other materials such as aluminum and copper. The heating process also requires high heat. Operating these processes at scale requires manufacturers to use large amounts of energy from traditional fuels such as gas, coal, and other fossil fuels, which releases harmful greenhouse gases and reduces the power of solar cells. Carbon emissions increase.

Solar companies need large tracts of land to install large-scale solar energy systems, and they typically clear everything, including vegetation. Ultimately, this can lead to loss of wildlife habitat.

Water resources diverted for solar projects can also harm wildlife. Additionally, construction of solar power facilities can cause 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, and brownfields.

As mentioned earlier, installing a solar power plant requires a large area of ​​land, which is completely cleared and causes soil erosion. Also, improper disposal of chemicals used during manufacturing can lead to water, air, and soil contamination. The manufacturing, installation, and transportation of solar panels also contributes to significant carbon emissions.

One way to reduce emissions is to replace the use of fossil fuels such as coal in production processes with more sustainable options such as renewable biomass.
