Well - I've explained the calculation behind the CNG figure - I hope its correct, but I'm not certain about it.
I've also ignored future growth in demand, so from that point of view it may be "unrealistic", in that it assumes that we get more efficient in our transport fuel usage or learn to live with less (which we'll have to do anyway of course).
I'm not sure how much use of oil we make outside of transport - presumably heating oil consumption is small compared to transport usage, but perhaps diesel fired power generation uses a large enough amount to make it worth considering as well.
I too am a little comforted in that your calculations suggest we could potentially make a relatively smooth transition to electrify our personal transport, assuming we don't export too much CNG. Hopefully we will eventually end up with something like green crude to power our trucks and planes.
