  • There’s a lot more nuance to this than most people will admit.

    Net metering is 100% unsustainable, when renewables become a big enough chunk of the grid generation mix, they often generate when no one needs the power. Forcing the grid to accept that power and even pay the homeowner a premium for it is a perverse incentive. Effectively what it does is allow solar array owners to avoid paying to maintain a grid they still use, and since the rich trend to go solar first, the poor are left holding the bag to maintain the grid for everyone.


  • Just pointing out that the grid is paid for by your electric bill, roughly half of what you pay is for delivery (paying to maintain the equipment needed to deliver you that energy), the other half is for supply (paying the power plant that generated the energy). So even if you and all your neighbors are energy independent you’ll still be on the hook for at least half your bill, or they’ll have to recoup it in taxes or something.

    Not saying that’s a bad thing, just clarifying a common misconception that going solar should not mean you eliminate your electric bill. In fact many places where solar does offset 100% of your electric bill are ending up with the rich owning solar and the poor paying to maintain the grid for them.


  • Yes and no, the progress of solar array technology continues unabated, with multiple areas of research that are beginning to reach commercial applications. Module conversion efficiencies now are in the 20% range, but heterojunction cells, or Gallium Arsenide, or Perovskites, or any number of other possible advancements could easily put efficiencies up into the 30% range.

    That being said, the price of the solar modules themselves has already shunk to a small piece of the cost to build a solar array, with the bulk of the costs now being the support structures, wiring, electrical equipment, labor, development, etc. And those costs aren’t going to decline, they’d still be there even if the solar panels themselves were free, so they effectively set a floor to the cost reductions we’re seeing.

    I’m going to chime in here to plug the ulefone power armor 18t I just got. I was pretty nervous to get a chinese phone as I’ve only had samsung and lg phones before, but this thing legit blows me away. Not only does it fully support every band that my carrier uses (rare even for phones made for the US market), but it has:

    • Replaceable battery that lasts 3+ days between recharges

    • Extremely rugged, IP69 waterproof and designed for underwater photography (physical shutter button and diving camera app)

    • 3.5mm jack, sd card slot, FM radio (with built in antenna - no headphones need to be plugged in), and an RGB notification led

    • Dimensity 900 chipset that beats a lot of the snapdragon chips on the market.

    • 12 fucking GB of RAM… yes, 12…

    • Wifi 6(ax)

    • Wireless charging and reverse charging

    • A fucking 60x magnification microscope? (Why???)

    • A FLIR thermal camera (Just because, why the fuck not)

    • Runs mostly bloat free stock android

    All that for under $600 (on aliexpress)

    The only thing it’s missing is an IR blaster, otherwise this is the best phone I’ve ever had, bar none. It is a chonky beast though, be warned.

    This has really changed my view on Chinese electronics, especially at a time when phones for the western world are losing features and functionality all the time (including stuff from South Korean). Turns out capitalism isn’t that great for innovation!
