Even if we have that much fuel left... That doesnt mean we have that much time left. The ecosystem will only tollerate so much. As temperatures rise, first world nations will spend more energy to cool buildings down, raising demand for more fuel. Additionally, world population is growing, basically doubling every 50 years.

Smart Grid is DESIGNED for intermittent use for varying demand that electric automotive would need. By nature varying power sources such as solar and wind are well suited for this because they cause the main fluctuations in supply, demand can be regulated with technology.

Finally, you state that coal/oil etc are practical and affordable. Sure if you are fine with global warming and all the expenses associated with it. GHG in the atmosphere are already estimated to cause in the hundreds of billions to trillions of dollars of damage.

I do not mean to make any of my points personal, but it seems that your view of what is affordable and practical are too narrow minded and only analyze the costs from the coal mine to your electric bill.
