Hahaha, finally you post something but it has nothing to do with the coal used to produce solar cells and how building solar period has increased our use of energy.Even with 2008 technology it was well worth it
The carbon/pollution/energy equation favored Solar after 1-3 years.
2008 - Scientific American.
"...In fact, most of their dirty side derived from the INDIRECT emissions of the coal-burning power plants or other fossil fuels used to generate the electricity for PV manufacturing facilities.These four types of solar cells pay back the energy involved in their manufacture in one to three years, according to an earlier analysis by the same team. And even the most energy-intensive to produce—monocrystalline silicate cells with the highest energy conversion efficiency of 14%—emit just 55 grams (1.9 ounces) of globe warming pollution per kilowatt-hour—a fraction of the near one kilogram (2.2 pounds) of greenhouse gases emitted by a coal-fired power plant per kilowatt-hour.Even though thin-film solar PVs employ heavy metals such as cadmium recovered from mining slimes, the overall toxic emissions are "90 to 300 times lower than those from coal power plants," the researchers write in Environmental Science & Technology.The energy benefits of solar photovoltaics will only improve as the technology continues to boost its efficiency at converting sunlight to electricity or proves to last longer than the 30 years anticipated by manufacturers. "There is no reason for this not to last a lot more than 30 years,"Fthenakis says.If solar energy begins to power its own production—a so-called PV breeder cycle, in which PV-generated electricity goes to produce more PV cells—the outlook is even sunnier. "I think 30% of the energy consumption in the [manufacturing] facilities is easily met from the land they have available [on] the roof and in the parking lot," Fthenakis says.(What I said. Solar powering Solar production)And, as Fthenakis and colleagues argued in a recent article in Scientific American, if storage technologies such as compressed air improve, then PV could provide the majority of electricity needs in the U.S. "With storage," Fthenakis says, "it is feasible to go to 100%."- - - - - - - - - -- - - -
Dark Side of Solar Cells Brightens
A life cycle analysis proves that solar cells are cleaner than conventional fossil fuel power generationwww.scientificamerican.com
And we now have that storage too and much nearer ' PV breeder solar.'Battery Technology has Exploded since the above 2008 article.But even then Solar well paid for itself environmentally/financially/pollution-wise after 2-3 Years.You have to get some better non-agenda links.Pull up your pants now BOY.I'm dome with your cheap shot One-sided and way Wrong BS.You Lost AGAIN!
`
Pay back time? We were not talking about pay back time.
I point out how you dodge, you make the outrageous claim that is me dodging, and here we have abo afuk dodging points, facts, and comments the dumbass made claims against.
Dodging, yep, you are Dodging because you can not address fact.
