Points about solar – The Recorder

According to the article, solar panels have a 20-year life cycle. What happens to the depleted panels? The solar panels contain chemicals, silicone, circuits and wiring; there is no “green” process to dispose or recycle them.

The article goes on to claim the arrays would “roughly” offset 27 million pounds annually over the 20-year period. Why doesn’t the same article include the tons of CO2 emitted by the extraction of minerals, refining, manufacturing, transportation (land, sea or air) and final installation of the arrays? Compare the total CO2 emitted up to final installation and the offset CO2.

How many years is the CO2 offset delayed to the break-even point? Five, 10, 12 years?

Re: Amherst 100% renewables: Let’s talk about energy efficiency.

Modern solar panels are at most 20% efficient. For a solar panel to obtain this efficiency, the sun must shine all day, every day. We all know New England weather; there are more cloudy than full sun days. During winter when the angle of the sun decreases. Our days around these parts are more cloudy, gloomy and darkish than sunny, rain or snow are more likely, lowering the efficiency rating of the solar panels precipitously.

Compare this to a clean oil furnace that can obtain an 80% plus efficiency rating. Or a modern natural gas furnace that tops out in the low 90s% efficiency — all day every day, no matter what the weather.

Now for my final point.

U.S. EIA, estimates that in 2019, the United States emitted 15% of the global CO2 emissions. If, somehow the U.S. reduced our emissions to zero, it would have a negligible effect to stop the so called climate calamity.
