What California is learning from solar panels built over irrigation canals

    It seems like it would be more effective to simply put all the solar panels in a field, and construct a cheap shade over the entire canal no? The supports in the picture are massive and don't look cheap. Also I would imagine the solar array uses more copper than a similar capacity array just built in a field. You can't daisy chain multiple miles of solar panels together, so you need an extra power line to run alongside the whole thing.

    Put the solar panels in a field: The solar array uses less copper. The shade supports don't have to hold up solar panels: Shade supports cost less.

    The best reasoning they give is that California has insane permitting requirements, and it takes 1/6 the time to build on developed land compared to undeveloped land.

      Anecdotally speaking, I have heard of a massive California solar farm in an undeveloped area that has serious vandalism problems. Junkies will find ways through the fencing at night, strip copper and other materials from panels, and cause thousands in damages and lost energy just to extract enough scrap for a fix.

      Nothing short of a face-to-face security response will deter these criminals, so there it is a challenging cost-benefit balance. At least panels in parking lots and other developed spaces have the benefit of witnesses. I'm sure a 20 foot climb up a steel beam over running water is a decent deterrent as well.

        I’m willing to bet if we gave them their fix they wouldn’t steal a thing. But because their fix is illegal they have to steal to get their fix.

        Seems to me like the root cause is the illegality of the drugs. I hope you never have to deal with substance abuse problems yourself. You won’t like being on the dehumanizing end of the stick that you’re presently poking with.

          If you're going to give junkies their fix, are you going to buy my alcohol too? What about my gambling debts? What about my escort bill for my sex addiction? Shy are you differentiating addiction to drugs?

            Junkies and meth-heads are a different kind of animal from your average drunk, and the reality of the proposal that you responded to is a simple economic analysis of investing in keeping them placated or paying for the damage they cause. It's far cheaper to prevent rather than react and repair.

            If we ended the War on Drugs we would be doing exactly this thing and saving billions of dollars doing it.

              Ending the war on drugs doesn't mean making all drugs legal. It means removing the stigma and jail time for people who use drugs.

              Some drugs are genuinely dangerous. Many are addictive and will damage the quality of one's life, even if buying and using the drug isn't illegal. Normalizing addiction to drugs as a regular, normal, accepted part of everyday life is not the answer.

                I'm advocating for all drugs to be legal -- regulated and taxed.

                Keeping them illegal does not "protect" anyone and just creates more crime, death, and misery. You've swallowed the propaganda -- it was never about protecting people, it was designed for oppression and it's wildly successful at that.

                Take a look at any video of police busting people for drugs: does it look like they're trying to help those poor innocent victims or are they gleefully enjoying their ability to completely fuck with those people in the name of "protecting" them?

                The fact that drugs are still such a problem despite countless billions of dollars shows that it's never going to work in the way that they promise.

                Drug addiction is a health issue, not a crime. My brother died of a heroin overdose and the law did not help him and the fact that the only resources public money went to were jails and prisons vs clinics shows where the priorities lie.
