There are basically two types of energy or fuel resources available for powering society, including our cars. The first is the type which has been dominant for a few centuries: the carbon-based fossil fuels Coal, Oil, and Natural Gas and their derivatives which are all long time frame solar resources. Nuclear Wikipedia:Nuclear Fission is also an even longer time frame solar byproduct, though because the materials aren't strictly terrestrial, having been produced in the hearts of long dead stars, it's generally tends to fall into the clean category as it is not carbon based. The other forms of energy which we will eventually be forced to transition to are short time frame solar resources or near-term solar resources such as PV electric and direct heat Solar, Wind, Hydro, and even forms of bio-fuels. All of these near and long term solar forms are the result of Wikipedia:Nuclear Fusion occurring in stars.
PHEVs are classified as green vehicles because of their potential to be free of fossil fuel when using biofuel and clean electricity from solar and wind power. PHEVs are also able to drive without range limitation or range anxiety. Most PHEV drivers will be able to fuel most of their short distance driving close to home with electricity, but the liquid fuel option (gasoline or biofuel) also makes PHEVs practical for long distance driving away from urban areas whenever needed. See: PHEV Vehicles of the Future. In contrast, all-electric vehicles are mostly limited to urban areas and high traffic corridors because the expensive rapid charging stations and/or battery swapping stations won't be available at every rural crossroads for the foreseeable future.

Here is just ONE comparison between Two very top-of-the-line Luxury Sedans. A Tesla-S and a Porsche Panamera.
The TESLA-S with a safe highway range of roughly .. 260 miles. (85 kw pack) And then compare how many gallons of High TEST to send an Audi A-8, or a BMW 7 Series, or a comparable Porsche Panamera the same 260 miles.
So at 9 cents a kwh, filling up a Tesla S to travel 260 miles =
 approx. $7.65 Agreed ??
A Porsche Panamera gets 19 mpg combined city/highway. To travel 260 miles that is 13.68 gallons, and at $3.90 a gallon that's
 $53 dollars and 36 cents !
Now THAT is a comparison worth mentioning. Two comparable Luxury Cars.
