Environmental Effects of Solar Farms

Solar energy is touted to be one of the greenest, cleanest sources of electricity. But you might be surprised to know that it is a potential threat to the environment. Well, no doubt, solar energy offers significant benefits compared to conventional forms of electricity production, but solar farms tend to have a deep environmental impact, from land degradation to habitat destruction and ecological imbalance. Let’s look at some of the issues that solar farms present to decide whether “green energy is clean energy.”

All Is Not Well With Solar Energy: The Risk of Emissions

Well, we all know that solar energy is one of the cleanest sources of energy, with no risk of global warming emissions. However, you might be surprised to learn that there are emissions associated with different stages of the solar lifecycle. To begin with, it is important to understand the solar panel production process. It all begins with the mining and processing of the raw material. Quartz, silver, copper, and aluminum are involved in the mining process. Quartz then undergoes further processing with hazardous chemicals in high-temperature furnaces to produce electronic grade silicon.

The major point of concern in the production process of silicon is the leftover silver content, which is considered a potential environmental hazard. The large-scale production of solar modules could amount to the depletion of silver resources.

The Risk of Solar Waste Disposal

Not much has been done on this front. The disposal of the chemicals involved in the production depends on the manufacturer, raising serious questions about the environmental safety. While there are responsible solar manufacturers that choose to safely dispose of solar waste, there are others that aren’t too concerned about environmental safety and don’t hesitate to cut corners to save money. Such irresponsible acts by solar manufacturers can cause more environmental harm than good.

Negative Effects Solar Energy Consumption

The production of solar modules consumes a high amount of energy. Additionally, the resultant water and hazardous byproducts are released into the environment during the manufacturing process.

The initial stages of the solar panel manufacturing process consume more energy compared to any other form of electricity production. The manufacturing process involves the transformation of raw mineral into usable photovoltaics. The different components involved in the processing, mining, production and cleaning of raw material may come from different facilities unlike conventional sources of energy production, where everything takes place at a single spot.

Besides, during the manufacturing process, the heating of quartz requires a lot of upfront energy. This can quickly amount to energy loss.

The Dark Side: Water Wastage

Like other conventional energy generation plants, some solar plants may require large amounts of water for cooling turbines and cleaning solar collectors. Increase in water demand could strain the available water resources. This may amount to the loss of large volumes of groundwater in arid locations, which may further impact the local wildlife that depends on these water resources. Besides, the use of chemicals, such as dust suppressants and dielectric fluids, may cause surface contamination or degradation of groundwater.

Environmental Impact: Habitat Degradation

The installation of solar panel farms requires clearing vast tracts of land, which could affect existing land uses, including agriculture, grazing, and mineral production. Clearing and grading of land may amount to habitat destruction and pose a risk of soil erosion and compaction. This may further interfere with the existing use of land and alteration of drainage channels.

Unfortunately, habitat destruction for the wildlife could result in a large-scale displacement of wild species. There have been reports of numerous bird deaths in California’s Ivanpah Solar Generating System. Reports blame the deaths on the solar farm’s mirrors, claiming that heat reflected from them burned off the bird’s wings.

The impact on one wildlife species can destroy the entire ecosystem since one species is dependent on another. When one is removed, the entire ecosystem of that species, comprised of plants, animals, birds, and marine life, can starve to death. The reason is that the habitat becomes less livable for the species that are dependent on each other for survival.

The conservation of wildlife habitat and diversity is a major cause for concern among environmentalists.

Recycling Is A Headache

One area that needs greater attention is recycling of solar waste. Recycling is likely to become a major issue in the coming times, as solar waste can prove to be a big burden on the environment. Recycling technology for reusing silicon from solar cells is not in place yet, though research has been underway to prove that the manufacturing of a solar panel from recycled components consumes significantly less amount of energy than solar module production from scratch.

Solar panel manufacturers need to delve deeper into the issue to mitigate the problem and focus on recycling.

The Hidden Aspect: Climate Change

While the world sees a climate change fix in solar energy, there is a debate among environmentalists whether this form of energy is worth it. There are concerns about the rampant development of solar panel farms and its impact on the broader environment. A report published in the Journal of Environmental Research Letters, titled “Solar Park Microclimate and Vegetation Management Effects on Grassland Carbon Cycling”, claims that there could be severe temperature reductions beneath solar installations by as much as 5 degrees Celsius in the hot season. This could affect plant growth in the surrounding areas.

However, a deeper understanding of the environmental impact of solar installations could enlighten farmers on microclimate changes and how to better utilize the vacant land under panels. Farmers may need to think deeper about choosing crops that can survive in low temperatures created by the shade of the solar panels.

The Bottom Line: Is Solar Good Or Bad

No doubt, although the large-scale development of solar panel farms can pose a danger to the local environment, the benefits of using solar power far outweigh the bad effects. Solar energy systems offer numerous environmental benefits compared to all other sources of energy, thus contributing to sustainable development. Solar power is still the cleanest energy source and is beneficial to the environment in more ways than one.

A renewable energy resource system, such as solar energy, reduces the need for fossil fuels to fuel electricity generation, helping us watch our carbon footprint. The need of the hour is to focus on proper planning and maintenance practices to minimize the adverse environmental effects associated with solar panel farms. After all, green energy is clean energy!

    Thanks the sol at farms are just so so ugly. I can’t imagine seeing them daily in My rural farm community. And will I get a benefit. Beside tax subsidising them and then paying a fee on my electric bill like we do for windmills. I’d rather see a windmill than a solar conglomerate of up to 3000 acres. Our farm community is rural but also populated. I prefer to see it remain rural not commercial. That’s why I moved out here.

    Back in 1983,scientists at the University of California had created this genetically-engineered ice-minus bacteria called Frostban.It was designed to protect
    crops from frost damage.When they were getting ready to field test it,Jeremy Rifkin filed a lawsuit to stop it.His main complaint was the National Institute of
    Health,in approving the test,violated the National Enviormental policy act of 1969 because it didn’t require an Enviormental Impact Statement,concerning the bacteria’s impact on the enviorment.So HOW come Rifkin’s not doing the same thing with these solar farms?He was all worried about Frostban’s
    impact on the enviorment.He should be doing the same thing with these solar farms.

    Exeter Rhode Island is a rural area being threatened by solar field development. Forests are clearcut and large fields obliterated for solar panels. Alternate sources of energy is a good thing but not at the expense of natural fields and woods. Profit is the primary motivation not environmental improvement. Alternate sources of energy can be developed in an environmentally responsible manner.

    Your right Christopher….not good for our environments…fire risk too!
    Local Electric companies can’t handle it…transformers blow due to “duck curves”! ….Local “County Managers, Planners and Commissioners” are like kids playing with matches…..these are “door to door” salesmen and women selling these panels…..Our Grandchildren will be stuck with the waste and cleanup….uhhh make that our Children…its going “south” that quick!.
    Just more carbon waste and trash from Asia!

    Hello, I know this is an older article (thank you, so very much for writing it, by the way!), but I was wondering if you had ever interviewed anyone that lived near a solar panel farm, or had leased their land for use of a solar panel farm. I was interested to read what their experiences were… the good, the bad, and the ugly.
