  • Just think about it in terms of the number of people and number of days per year where they need to raise the indoor temperature by a certain amount, compared to the number of people and days needing to lower the temperature.

    If you’re looking at a place where it’s 95°F during the day and 85°F at night, and you like to set the temperature to 75°F, you’re only cooling it 10-20°F by time of day.

    But if you’re looking at a place where it’s 35°F during the day and 15°F at night, and you want to heat things up to 65°F, you’ve gotta change the temperature by 30-50°F throughout the day.

    Even when you’re comparing absurdly hot weather to absurdly cold weather, you’re still comparing something like 110°F to 0°F. You’re still looking at a 70°F swing versus a 35°F swing towards comfort.

    Throw in the fact that combustion of fuels (fossil fuels like heating oil or natural gas, or other fuels like wood in a fireplace) is usually only about 1/3 or 1/4 as energy efficient than the equivalent temperature change by heat pump, and you can see how much more energy intensive the typical indoor heating setup is compared to the typical indoor cooling setup.

    Some of it is obscured by the fact that fossil fuels are much cheaper per unit energy than electricity from the grid, so that heating bills aren’t as expensive in the same ratio, but in terms of actual energy used, it’s a big difference.



  • I was flabbergasted the first time I realized just how far north Europe is, compared to North America.

    Paris is at 48° 51’ N, significantly further north than Toronto (43° N), Montreal (45° N). London is at 51°N 30’, which is further north than Vancouver (49° N), and just slightly further north than Calgary (51°N).

    Even southern European cities like Ibiza (39° N) are at comparable latitudes to northern American cities like Philadelphia (40°N) or even New York (41°N).

    If Europe starts seeing climate comparable to similar latitudes in North America, that would represent a huge change from the recorded history.



  • GFCI doesn’t protect against arcs, so AFCI would be necessary to protect against arcing causing fires.

    The danger with outdoor outlets is short circuiting (like when water drips onto a live wire), so GFCI is almost always required of outdoor outlets. Generally, outdoor outlets also require covers that keep the receptacle dry, at least when not in use (and more modern code generally requires it have an “in-use” cover that can stay on even when something is plugged in).

    But having GFCI isn’t the same as AFCI, so arc fires can still theoretically happen.


  • Also, I’d push back against the subtext that work experience gives skills. Plenty of people work a job for 10 years without having the adjacent job skills to be able to progress in that career or jump to another.

    Critical thinking skills are the most important thing, and it’s possible to get a 4-year degree without actually picking them up or strengthening your skill sets in that area. But it’s also possible to work for 5 years without developing critical thinking skills, either.

    In the end, no matter what you do with your time, only a small percentage of your effort is going into improving yourself. The people at work are trying to get stuff done for their employer, and the people at school are trying to get through the curriculum. It’s possible to do the work while the employer/school or even yourself cheats you out of the real long term benefits of actually learning during that time frame.
