    Default Resources used to build "green" cars

    The fuel efficiency benefits of green cars are compelling, but has anyone done any research regarding the amount of resources (energy, coal, electricity) etc. required to build one car? I often think that it would be better to just buy a used car to avoid the pollution involved in the manufacture of a new green car.

    A used car is a good alternative but think of its engine efficiency too. It might be emitting more CO2 than newer more efficient cars and in the long run we'll only be adding to more carbon in the atmosphere, more than what it took to create it.

    One of the problem is that we consume too much than is necessary. Why do you think there are all these used cars for sale? Most of the reason is that people change cars too often. Even perhaps have one too many cars than is also necessary.

    a more important question is for what you use your car
    most people do not think about it but they only drive a few miles with their car on a regular basis but they still have big heavy cars or cars which a suited for long trips...the thing is they use a lot of fuel because they are not built for short trips.
    car companies started to catch up with start stop automatics and so on... another thing is that people love to floor the gas padel etc...which burns additionally unnecessary...
    so in general for the overall use new cars are better if used properly and do not forget the safety issues...older cars i mean over 5 years have lower standards and so on...

    Default ours cars must be covered with a plastic at night. Doing so they will last 25 years.

    1- The fuel efficiency benefits of green cars are compelling, but has anyone done any research regarding the amount of resources (energy, coal, electricity) etc. required to build one car?


    excellent.
    you are smart.
    we need so many energy coal and electricity to build a car.
    but worse we need so many employees. Designers, engineers, technicians, marketing employees, and employees.
    Must feed all this employees with food.
    Must transport this food to this employees.
    Must transport this employees to work.
    and so on.
    it’s a long process. So much energy required to build a car.
    Then when we built a car, we must use this car during 25 years. Several owners.first hand owner, second hand owner, and so on.

    It doesn’t mean that the one who buy it new must use it during 25 years.

    And today there is a massacre going on.
    Millions of people buy a car.
    And this idiots don’t know that a car rust under the rain.
    Millions of people let the car outside during the night.
    That’s an ecological massacre.

    A beautifull car, a motorbike, a truck, a train, a subway, an excavator, must not stay under the rain at night.
    if a car is covered every night with a plastic cover, it will not rust.
    If a car stay oustsie at night without plastic cover, it will rust early.
    After 10 years this car will be rusted.


    We must protect our items, we must maintain our items.
    So they will last during long time.
    So we will not extract row materials so often.
    So we will not use so much energy.






    2-a more important question is for what you use your car
    most people do not think about it but they only drive a few miles with their car on a regular basis but they still have big heavy cars or cars which a suited for long trips...the thing is they use a lot of fuel because they are not built for short trips.




    good also.
    the car it’s a one tone machine.
    We use it to move a 70 kilos body in average.
    for short distance, we must use a scooter.
    simple efficient, need so few oil.




    3- A used car is a good alternative but think of its engine efficiency too. It might be emitting more CO2 than newer more efficient cars and in the long run we'll only be adding to more carbon in the atmosphere, more than what it took to create it.


    Interesting. But we should change the engine for a high end one, while keeping the car.
    CO2 is a fashion talk.
    5 years from now we will not talk about it any more.

    frankly the car makers cheated us.
    They force us too buy new models. They produce too many cars. We don’t need so many.

    An engine is just one little part of a car.
    We should be able to remove it easily,
    After 5 years, We should be able to replace the engine easily with a new high end engine, more efficient.
    We must buy a good brand. Reliable.
    We must protect our cars against the rain.
    Doing so it will last 25 years.
    And every 5 years or something like that, we replace the engine with a more efficient one.

    That will be ecofriendly.
    less row materials, less energy used for building cars.

    the amount of resources (energy, coal, electricity) etc. required to build one car?
    We need more enery to built a new car as the energy gas we need to put in it during it's whole live.

    That's so important.
    We must take very good care of our cars.
    When we have one, we must prtected it. We must put it in a parking lot at night,
    It must not sleep under the rain at night. it must be cover with a plastic cover,
    So it will last years and years. So we don't need to built a new one.
    Because it cost so much energy to buit a new one.

    And we must buy a reiliable brand. A good brand. So it will last years.
    If you buy a cheap brand, a bad quality brand, it will break down very quicly.
    You will throw it to the garbage too early. The energy that was being used to built it
    will go to waste. buy a good brand, protected it against the rain at night with a plastic cover my friend.

    There are a lot of people bashing electric cars and the resources that are used to make them. I work with the Martin Hanzalek institute here in Newfoundland and we work first hand with building alternative electric vehicles here in St. John's - everything from electric bikes to trikes to solar powered personal cars. It is true that some of the lithium and battery technologies do produce a considerable amount of waste, especially now in the inception of the industry, but it is nothing compared to the carbon cost of gasoline powered transport. You have to remember that the technology is in it's infancy / inception and is still making leaps and bounds when it comes to improvement. Compare that with the combustion engine that has really not changed at all in the last 50 years and you can see why electric technologies are a winner.

    Default e cars, it doesn't work

    I work for a research institute, people very smart. I know about cars.
    You are from Canada, this country know nothing about building cars at a large scale and cars technology.
    Canada doesn't build any vehicles : Cars, motorbikes, tracks, buses. Canada is not really an Industry country. They don’t produce mobile phones, computers, industry tools machinery high tech
    German people, Japanese, USA, French, sweedish, Koreans, Chinese, Indians are the only one on earth who mass produce vehicles.
    Just people who doesn't anything about electricity believe in Ecars.
    Do you think that the electricity come from a spring in the mountain or something?
    Electricity is made with crude oil or gaz or nuclear plants or coal.
    That kill our resources at first, and it pollutes so much.
    This city electricity plants exhaust so much carbons.
    And the worth things is that only 30 percent of what they produce arrive to your house.
    65 percent get lost during the electricity wire travel.
    So electricity is the worse energy in fact.
    Just it's enable people like you to receive a good paycheck by making the population believe that it's the future.
    In 1920 the first cars were already electric. You invent nothing. Just make people believe of a future things.
    Scientists i know them, they can't see the elephant right in front of them.
    And they think making money at first. Even if they reinvent something that will never take off.
    A car weight one tone. and a human weight 75 kilos.
    Then our vehicles must weight 80 kilos maximum and drive at 50 kilometers an hour.
    In the cities at least.
    Will take 20 years to the scientists to understand that.
    .
    Our cities must be less poluted. The electricity can't just move anything right now.
    An ebike must be reloaded every 4 hours.
    An ecar must be reloaded every five hours.
    Just must not produce this useless things. That's a con, money extorsion. People from the population buy that and can't drive it in fact. They abandon it in the garage after 2 months.
    That's the reality.
    Now we can only use gas scooter. It's uses so few gas. That doesn't produce any carbon compare to a car. Like 5 times less carbon as a car. Ans you can commute with it. Nothing elese works right now.
    And if the popuation use at a large scale this gas scooters with roofs, then we can mass produce biofuels.
    Even if it's more expensive, biofuels will be very affordable for the 5 liters of a gas scooter.
    Stop your research about ecars. You will never be able to move a one tone car during three days, with bateries that last five years. Think weight, must be more light! you blind scientist!. No need anymore of this one tone matal box. I m more smart than you.

    Default Martin Hanzalek Alternative Transport

    In response to your reply, it is true that a lot of electric generation is made from burin ing oil and coal, especially if you live in a pollution stricken country like China. Here in Newfoundland Canada we may not produce a lot of parts, but we make a lot of electricity, and all of it comes from hydro (water power). It's clean, emission free, and powers a place several times the size of England. We also use wind generation, as do a lot of places in the world. For us here electric bikes and electric cars make sense, and definatly help conserve our planet. The Martin Hanzalek foundation is doing a lot when it comes to advancing electric alternative transport technologies here in Newfoundland and Labrador. We don't manufacture our parts here, but we give people viable transport technologies that they can take advantage of. Very easy rider: an electric bike adventure - Arts - Life - The Telegram

    Default Surprisingly, it's not as bad as you think.

    CelloMom went digging into the lifecycle analysis for automobiles, and makes some astonishing discoveries. The "average" car actually takes a lot less energy to build than to drive (over its lifetime). So if you have a gas guzzler:
    From the green perspective: trade it in!
    From the greenback perspective: keep it till it falls apart.
    Check it out here: What is greener: drive your old gas guzzler it till it dies, or trade it for a new gas sipper?

    And here is how to figure total energy use for your specific car:
