  • Meanwhile, let’s also face that EV’s have to carry around large batteries. One advantage that ICE cars do have is the power density [J/kg] of petroleum fuel is leaps and bounds better than that if a lithium battery. This means that EV’s are likely to produce more road noise from rolling, the dominant source of noise above 50 km/h, as well as more wear to the roads, since wear is a function of vehicle mass to some pretty high power. (I thought it was m^(4), but I’m not sure)

    On top of that, while EV’s don’t have any tailpipe emissions, the power that they need still needs to come from somewhere. Thus the carbon emissions for use are a function of the national power grid of the place where you’re charging your car.

    Thus, A) if cars are already a fairly small part of the transportation mix, B) steps are taken to further improve the quality and availability of alternatives to cars, and C) the power grid is dominated by nuclear power and/or renewables, then EV’s could be better for the environment.


  • The cynical take is that EV’s don’t exist to save the world, they exist to save the car industry.

    The more neutral take is that between an EV and an ICE car, the former is preferable.

    Fact of the matter is that in order for many people to use a private car to go from anywhere to anywhere, you need a shocking amount of space and resources to make that work, especially if you compare that to expecting most people take those journeys by mass means, by bicycle or by foot.
    So if you propose electric cars as the silver bullet solution for climate change, in a place where walking, cycling and transit are systemically kneecapped and held back, and nothing is done to solve the latter part, then the environmental impact of EV’s is a drop on a hot plate.


  • That. And usually the stick is a very metaphoric one. As long as mechanisms of power exist, someone will have some kind of upper hand in any and all situations with other people.

    For instance, if you’re rich, you can throw more money at a situation and buy good results. If you have a big army, you can threaten someone into doing something for you and they know you have the manpower to back the threat up with actual force. And if you have a lot of connections, you can get stuff done via good will.

    Ultimately, you need a government that, as a unit, has the authority to say “WE are the top dogs and there is nothing you can do about it.” Ideally that system is malleable enough by its subjects to always act for the betterment of its subjects, and to hold its members to account.
    In the absence of a formal government, that position is filled up by someone else. Either whomever shouts the loudest, has the most friend in the best places, has the biggest pile of money, has the biggest group of bullies, or some combination of those. In fact, that is how most kings’ dynasties in history probably got established.

    Just like nature abhors a vacuum, society abhors a power vacuum, and the moment you get rid of a king and do nothing to follow up on his removal, someone else is gonna take the throne and the crown and make himself king.

    And before you start the republic spiel or the representative democracy spiel, a republic and a house of representatives are basically a royal court with more checks and balances, where the people on the outside as a whole get a say in who’s in that court. It’s basically regularly emptying and refilling thrones and having rules on how to do so.
