  • This is being talked about because it’s a hot topic around the world, with many states and countries introducing or planning to introduce age check based restrictions on social media.

    Honestly based on how Facebook money was traced to the plan to push age checks to the OS instead of the service, I wouldn’t be surprised to find a nice donation to Act behind this too.

    Ultimately I think most people would agree it’s better than the age checks on sites that the government have been suggesting so maybe we have to take our wins when we get them, in whatever form they come.











  • It does make getting a 20+kwh house battery an absolute no brainer though.

    On the face of it, the numbers seem to work. This site says the average grid cost in Australia is 31c/kwh which seems about right I guess. So assuming you could charge and use all 20kwh every day, you could save $6.20 per day or $2263 per year. $15k AUD or so for a 20kwh battery makes a but under 7 years to pay for itself.

    Batteries have a loss of around 10% of the energy during the charge/use cycle, so you’d get about 18kwh of actual use. But that doesn’t matter that much because according to this website the average power usage is 3,900 kWh per year, which is 10.6kwh per day. So it may take you 13+ years to pay it off.

    Yeah that’s pretty worth it. I don’t know the lifespan of the battery but it seems it should be more than 13 years. I calculated the pay back on our battery was about 40 years 😬 (assuming it kept full capacity all that time).

    This may be pretty smart actually. To solve the problem, many places (including NZ to some extent) are doing grid-scale batteries. But this way you can encourage people to get batteries, you get a grid-scale battery spread over millions of houses and you don’t even have to pay for it.
