  • Yes we should use petrol for cars

    It will be necessary for some time to continue to use petrol as the fuel for our autos. Our infrastructure is set up for this and to change will be a huge financial issue. I do agree that we need to supplement petrol with other alternatives such as hybrids and electronic vehicles while developing that infrastructure, too, but petrol is here to stay for some time.

  • Petrol Should Be Used For Cars

    I think that we should use petrol for gas. It has been done for a while now and seems to be very reliable and sufficient. Although I do think that society needs to be creative and think of some alternatives to petrol because it has a ridiculously high price these days.

  • Its time to move on

    What we have to remember is that burning petrol is hugely inefficient, a good engine will at the very most give you around 28% efficiency, the rest is wasted as heat compared with an electric motor of which some modern ones crack 98%. Even if you burn coal to produce the electricity its far far better for the environment. Just think how much energy it takes to drill, refine, pump, and store petrol, maybe 7.5 kwh of electric to refine a gallon of petrol, that would run an electric car for 30 miles. So why not just use the electric in the first place? Oh and dont forget that most the electric for the oil refining is done by burning huge amounts of coal.

  • No, we should not. But we will for some time to come.

    The limited resources required to fuel our ever growing transportation fleets demand that we find alternative and renewable energy solutions. There are many alternatives on the road now with mixed results (natural gas, electricity, bio diesel, hybrids, etc). There are of course many obstacles keeping us from moving to these solutions such as storage (batteries), infrastructure, and range (mainly in the US). It's possible that a ten dollar gallon of gas in the US might speed up the transition to new fuels in the US.

  • It depends on your perspective.

    Petrol was has been used for a pretty obvious reason, with the technology that was present when cars became popular petrol was the best combination of efficiency and availability. Times have changed however and so has technology.

    As the market stands now, petrol is still the most economical option, but that is quickly become less and less true. As engineers continue to make advances in storage technologies and solar/wind/hydro become more and more common sources of electricity, electrically driven cars are going to be the best option.

    Currently the Nissan Leaf will, in a week (estimating 10 trips of less than 30 miles) save a consumer roughly $6 in spending when compared to a car that runs on petrol (this is using a fuel cost of $3.45/gal)
