    Plus methane is a much stronger greenhouse gas than CO2, even with the shorter lifetime. We seem entirely unable to reduce methane leaks or even measure them against natural gas usage.

    But from a consumer perspective.

    • where I live, electricity is much more expensive than natural gas, maybe double the cost per unit of energy
    • and I pay even more for 75% renewables
    • I just got a heat pump installed for my addition. So far temps have gotten just a bit under freezing and it has no problems keeping up

    But that adds up to a reality where the cost threshold is mid-40°F’s. While it may be an argument in favor of solar, I don’t have enough unshaded roof to generate more than half my usage


  • Signing (intermediate) certs have been compromised before. That means a bad actor can issue fake certs that are validated up to your root ca certs

    While you can invalidate that signing cert, without useful and ubiquitous revocation lists, there’s nothing you can do to propagate that.

    A compromised signing certs, effectively means invalidating the ca cert, to limit the damage

    green alone isn’t going to support our society

    Let’s find out. When I started advocating for increased renewables, the expected limit was the grid destabilizing at 30% renewables. Now many places are there. I recently read a piece expecting the limit to be about 95% renewables based on scalability of todays grid storage. Were a long way from that, so let’s work toward it and see what improvements we can make along the way

    Note: one of the more difficult areas to greenify will be the military, but imagine instead shrinking that as we no longer have to defend petrostates or fossil fuel trade routes

    Imagine the savings to society with the energy independence from green energy

    • shut down most of the continent wide natural gas distribution infrastructure
    • shut down most of the continent wide gasoline distribution infrastructure
    • cut way back on the military when we no longer have to protect oil kingdoms
