A little insight into the reality of solar energy:
Here in New Mexico, a very solar friendly state, if you are served by a power grid and put up panels on your business or home, you are required by law to feed the power to the grid, not your business or home directly. One solar company I spoke to said that a good electrician could route the power to your home, but it would be a bad idea without storage devices and capacitors to regulate the power flow. If you generate more than you use, then you are ostensibly running on 100% renewable energy.
Solar panels have gotten MUCH better as of lately. Current estimates are for a less than 10% reduction in efficiency over 30 years with many solar companies offering 30 year warranties with efficiency guarantees.
Any time DennisW von Munchausen posts in an Apple thread you can be absolutely certain not a word in it is true.
In this instance, both the article, and the Barron's comments are vying for which one is the most untruthful. As I pointed out, the most efficient way to handle solar power is to connect to the grid, piping your power generated into the grid, selling the generated power to the power company and then buying what you need. This avoids the necessity of having to buy very expensive power accumulations systems such as batteries or capacitors for storage for later use, puts your excess production to immediate use, ameliorates the utility's need to build more power plants, and simultaneously provides YOUR need for clean, steady, guaranteed available power 24/7. That's a win-win that the article author and TruthOut just don't seem to grasp in claiming that Apple was lying when they claim their facilities of now 100% self-sustaining.
As a matter of fact, Apple's solar generation is a profit point for Apple. They make money by selling power to the local utilities around their plants because they generate more power than they use.
I would not trust any of those 30 year (lol) guarantees. I would not trust any of them to actually transfer cash back to me in event of "premature" failure of solar panels.
Just think it through a bit. Sensitive diodes are exposed to harsh sunlight to generate electricity... and they do not degrade??? and a lot more than that bs 10%
Not attacking you. Just the solar propaganda out there
