As if gasoline came out of the pump LOL Tesla posted on Facebook that the Model S needs only as much energy as is needed to refine oil to gasoline. The fact we are fighting global wars over oil, the massive environmental impact of drilling oil around the globe. The oil based dependency on countries that we really shouldn't deal with in the first place. The huge amount of money we are giving them. I could go on an on. Everything that happens just to get the oil to where we live and into the gas stations is already so bad that we should be looking for alternatives much faster and harder. Producing your energy local, even if it isn't perfectly clean, is still so much better in so many ways.
It is much more efficient to have one large generator/turbine that is made for high efficiency than trying to fit a small engine into a moving vehicle that requires a large dynamic range of power output. It can never be as efficient. Electricity can be generated from a variety of sources. Many are more environmentally friendly than burning gasoline.
But it's not just the smoke. Think about the noise. Especially here in the USA there is an unbelievable amount of people that think making a lot of noise when they drive is awesome. Living next to a busy road is considered terrible because of the constant noise. Make them all electric and the noise is reduced significantly.
I hate when people point out the EV isn't the perfect solution because it's not 100% eco-friendly. So what's the argument here? Because there is no perfect solution (as if there ever was a 'perfect' one), let's just stick to the 120 year old stone age technology of creating a bunch of little explosions to move? Since when was being better but not perfect an argument to keep a really bad solution in place?
