  • In much of California, it’s not the electric energy costs that are high, it’s the delivery/grid fees. Not that it matters as far as the electricity bill goes, but it’s worth noting.

    On my recent bill I paid 16¢/kWh for on-peak electric generation and 49¢/kWh for electric delivery. (There’s a small baseline credit for delivery so it’s a little more complicated, but you get the idea.)

    So if someone tries to tell you electricity is expensive because CA is a hippie state with lots of solar, I would be a little skeptical.



  • Yeah I’ve been very happy with them.

    No experience with their software, but the service is great — I have an ARM SBC with WireGuard handling my tunnels, and my router does the rest (so my TV/guest SSID/personal SSID/whatever can get routed over Mullvad with no client setup). My DNS forwarders are each routed through a different Mullvad interface too.

    High frequency is generally bad for transmission line losses, so getting power from A to B is better at lower frequency — DC is a great option here.

    If we switched to DC, many things would still flicker though as they would presumably use switching power supplies, but those could be relatively high frequency like you said.

    Interestingly, airplanes use 400Hz, as transmission over distance doesn’t matter, and transformers can be made much smaller/lighter.
