Cadmium telluride (CdTe) photovoltaics or also called Cadmium telluride solar cell is a kind of photovoltaic (PV) technology that can produce electricity from sunlight using a thin-film of compound cadmium telluride to absorb and convert sunlight into electricity. Where are your scientific papers, your verified measurements? Common problematic impurities in glass include plastics, lead, cadmium and antimony.”, Researchers with the Electric Power Research Institute (EPRI) undertook a study for U.S. solar-owning utilities to plan for end-of-life and concluded that solar panel “disposal in “regular landfills [is] not recommended in case modules break and toxic materials leach into the soil” and so “disposal is potentially a major issue.”. “Any modules that were broken into small bits of glass had to be swept from the ground,” Mulvaney explained, “so lots of rocks and dirt got mixed in that would not work in recycling plants that are designed to take modules. The editorial board of the Wall Street Journal? They just want them cheap… There, there is lots of land to install a large amount of panels to make up for their low performance. So if recycling is properly conducted, the toxic materials can be recovered and reused. Cadmium telluride solar cell, also called cadmium telluride photovoltaic or cadmium telluride thin film, a photovoltaic device that produces electricity from light by using a thin film of cadmium telluride (CdTe). Solar panels glimmering in the sun are an icon of all that is green. Portions copyright © Principia Scientific International. A dilute aqueous solution of hydrogen peroxide and sulfuric acid was sufficient to completely leach … Silicon is the same element in sand, and is non-toxic. Additionally, he said cadmium is considered 10 times more hazardous than lead. Low demand for scrap and the high cost of employing workers to disassemble the aluminum frames and other components will make it difficult to create a profitable business unless recycling companies can charge several times more than the target set by [Japan’s environment ministry]. Research paper by Adriana A Ramos-Ruiz, Jean V JV Wilkening, James A JA Field, Reyes R Sierra-Alvarez. Industry often prefers to comply with a single national standard rather than multiple different state standards. My writings have appeared in The New York Times, Washington Post and Wall Street Journal, Scientific American, Nature Energy,…, Michael Shellenberger, President, Environmental Progress. For this reason, the whole solar panel is considered hazardous by many experts and governments, including the state of California , which is trying to prevent the flow of old solar panels to landfills. James McGinn: If so show it — AND STOP SHOUTING ABUSE! Is Sustainable Energy Even Possible Globally? But it is notable that some new forms of electronic waste, namely smartphones like the iPhone, have in many cases replaced things like stereo systems, GPS devices, and alarm clocks and thus reduced their contribution to the e-waste stream. The fact that cadmium can be washed out of solar modules by rainwater is increasingly a concern for local environmentalists like the Concerned Citizens of … While even silicon based solar panels have their own problematic element – lead – Mr. Westgaard says tests have shown lead leaching potential of approximately 4 grams of lead per kilowatt installed compared to approximately 23 grams of cadmium per kilowatt installed for CdTe panels. You are just one of many, many ideologues using the atmosphere as the canvas to express your politics. That claim has been contradicted by the previously-mentioned Stuttgart research scientists who found cadmium from solar panels “can be almost completely washed out…over a period of several months…by rainwater.” With few environmental journalists willing to report on much of anything other than the good news about renewables, it’s been left to environmental scientists and solar industry leaders to raise the alarm. I am a Time Magazine “Hero of the Environment,” Green Book Award Winner, and President of Environmental Progress, a research and policy organization. None of the above. Last July, Washington became the first U.S. state to require manufacturers selling solar panels to have a plan to recycle. Sci. — and at decommissioning is a big concern.”. They are really only good for the end user who is isolated from the grid or wants to use less power from the grid. According to a 2015 United Nations Environment Program (UNEP) report, somewhere between 60 and 90 percent of electronic waste is illegally traded and dumped in poor nations. Meteorological theory has always been a religion based on traditional values, couched in scientific vagueness and self-righteous dimwittedness. What do Christmas trees have in common with aleo solar modules? https ://www.thunderbolts.info/forum/phpBB3/viewtopic.php?f=10&t=16460, Accounting For Lorenz’s Missing Lubrication in the Atmosphere Solar cells, wind bird shredders and biofuels are net energy LOSERS. The International Renewable Energy Agency (IRENA) in 2016 estimated there was about 250,000 metric tonnes of solar panel waste in the world at the end of that year. Such a recycling and waste management fund could help nations address their other e-waste problems while supporting the development of a new, high-tech industry in recycling solar panels. To me you guys are just as lost as all the meteorologists and climatologists are currently — and all of you are shouting loudly that you have the truth. California’s Department of Toxic Substances Control (DTSC), which is implementing the new regulations, held a meeting last August with solar and waste industry representatives to discuss how to deal with the issue of solar waste. Alternate silicon-based solar panels have similar issues with lead leaching, although cadmium is suggested to be 10 times more hazardous than Lead. When growth levels off then PV producers would face rapidly increasing recycling costs as a percentage of revenues. Why Do Jet Streams Exist? But the legislature did not require manufacturers to pay a fee for disposal. If the industry responds with foresight, Mulvaney notes, it could end up sparking clean innovation including “developing PV modules without hazardous inputs and recycled rare metals.” And that’s something everyone can get powered up about. They dare not sue, because to do…, Does this come as any surprise? There is growing concern over the possibility of rainwater washing cadmium out of panels … Photovoltaic panels never produce a fraction of their investment energy. ... First Solar has meanwhile been steadily reducing the amount of cadmium used in its solar cells. Go back to your “Green Peace” (haha .. what a joke .. neither “green” nor “peace”). Leaching of cadmium and tellurium from cadmium telluride (CdTe) thin-film solar panels under simulated landfill conditions. James McGinn: AU - Ramos-Ruiz, Adriana. “If a recycling plant carries out every step by the book,” a Chinese expert told The South China Morning Post, “their products can end up being more expensive than new raw materials.”. ” said EPRI’s Cara Libby. Till you can answer those simple question then you are as lost as the rest of us. The rest of a solar panel is made of the aluminum frame, a glass cover, a couple layers called the encapsulant and backsheet which are made of various plastics, and the wiring. Field Reyes Sierra-Alvarez I could expect a brainwashed school kid to say that but a doctor – incredible. Second, the federal government should encourage citizen enforcement of laws to decommission, store, or recycle solar panels so that they do not end up in landfills. Currently, citizens have the right to file lawsuits against government agencies and corporations to force them to abide by various environmental laws, including ones that protect the public from toxic waste. Perhaps you have the correct course, perhaps you are on the right road, without verified evidence you have nothing! Principia Scientific International (PSI) is a not-for-profit community interest association. “We estimate there are 100,000 pounds of cadmium contained in the 1.8 million panels,” Sean Fogarty of Concerned Citizens of Fawn Lake stated to Shellenberger. “The theory behind the regulations is to make [disposal] less burdensome,” explained Rick Brausch of DTSC. In 2012, First Solar stopped putting a share of its revenues into a fund for long-term waste management. Meteorologists have been getting away wth the same tactics for 170 years and you never noticed. — and at decommissioning is a big concern.” I’m not running a hand holding service. Dangers and hazards of toxins in photovoltaic modules appear particularly large in countries where there are no orderly waste management systems… Especially in less developed countries in the so-called global south, which are particularly predestined for the use of photovoltaics because of the high solar radiation, it seems highly problematic to use modules that contain pollutants. Like all the rest of the pretenders that populate PSI, you only started caring when you saw that your political opponents were getting away with something. “We estimate there are 100,000 pounds of cadmium contained in the 1.8 million panels,” Sean Fogarty of the group told me. The type of solar panels that are by far the most common on homes are made of crystalline silicon (c-Si). ‘COVID-19: The Politics of a Pandemic Moral Panic’ – Book Excerpt, Researchers: people irrationally reject anti-lockdown findings, Israeli Scientists Prove Trump Correct on UV Light Killing COVID19, ‘This Is Not a Vaccine, it Is Irreversible Genetic Modification’ say Doctor, Coronavirus – A perspective from Britain Part 18, Solar flare in 774 AD changed Earth’s atmospheric chemistry, Science That Doesn’t Add Up: A Discussion Paper, Professor Dolores Cahill: People Will Start Dying After COVID Vaccine, Greenhouse Gas?
