  • I worry about what this legislation could mean for medium-sized cities like where I live that are only now starting to put in bike infrastructure. It is underutilized at this point, but that’s because it is still incomplete.

    You have, for example, a wonderful off-road trail that is 90% complete connecting the suburbs to downtown, but there is one section where you have to cross a bridge with no bike lanes or anything. Until that part gets done, few people will use the rest of it. But if they decide to take a lane away from cars on the bridge, the province could argue that no one uses the trail in the first place and shoot it down. Uuugh!

    I was recently in Montreal and omg it’s cycling heaven! Bikes outnumber cars in many places and vehicle congestion seems less in spite of this. Also, drivers seem more cautious in general in the downtown core, even on roads where there are no cycle tracks. It’s a bit like the college campus effect I guess? When you have a high density of non-automotive road usage, the cars tend to slow down and be more patient. They’re moving slower but there is still a steady flow of traffic. Not a lot of gridlock.

    But the mining, milling, and production of nuclear fuel, as well as the construction and decommissioning of nuclear plants, emit greenhouse gases at levels ranging from 10 to 130 grams of carbon dioxide per kilowatt hour of power — lower than fossil fuels but higher than wind and hydroelectricity (and roughly on par with solar).

    That’s interesting. The article they link gives a bit more detail:

    These energy intensities translate into greenhouse gas intensities for LWR and HWR of between 10 and 130 g CO2-e/kWhel, with an average of 65 g CO2-e/kWhel.

    While these greenhouse gases are expectedly lower than those of fossil technologies (typically 600–1200 g CO2-e/kWhel), they are higher than reported figures for wind turbines and hydroelectricity (around 15–25 g CO2-e/kWhel) and in the order of, or slightly lower than, solar photovoltaic or solar thermal power (around 90 g CO2-e/kWhel).

    The wide range for nuclear apparently comes from difficulties in estimating the carbon footprint of mining/processing the uranium, but that nuclear is sort of in the middle of the pack in carbon footprint relative to renewables in spite of the fueling costs is good to know.

    I suppose these sort of numbers may change dramatically in years to come. Take solar. A lot of focus seems to be on the efficiency of panels, which would almost certainly lower the carbon cost per unit of energy as it improves, but a breakthrough in panel longevity would also do that in an amortized emissions sort of way.









  • I guess the central premise of capitalism is that while every society has its haves and have nots, capitalism is supposed to encourage the haves to invest in the economy rather than hoarding their wealth. In return, they stand to get even wealthier, but a stronger economy ought to generate more employment and generally improve the lives of commoners as well.

    Unfortunately, in a never-ending quest to make wealth-generation more efficient and streamlined, employment is being eliminated through automation, outsourcing, etc. and the system is eating itself out from the inside. I doubt it can persist much longer, but what will replace it remains unclear. I pray that it will be something sensible that ensures everyone has their basic needs met and can still find rewarding pursuits in life. But there are so many ways it could go very wrong, and that includes staying on the current course.
