$this->bbcode_second_pass_quote('TonyPrep', 't')he scale of energy we need to substitute for the energy dense sources of oil, then gas, then coal is almost mind boggling [...] Even if the decline is slow (perhaps an undulating downslope with occasional, but lower, upturns), it is this scale of energy substitution that you never sem to address.
I address it often: If the decline is slow, substitution will start from a small base, but will grow exponentially, and the substitution will be completed over a long period of time. As you know, exponential growth is an amazing thing, and can grow very large, given *time*.
You're falsely exaggerating the seriousness of the immediate problem when you lump oil, gas and coal together.
We don't need to substitute the entire amount of all of them all at the same time. In fact, for quite a long time, gas+coal (among nuclear and other things) will be used to substitute for oil. The immediate task (assuming a slow decline) is to substitute a 1-2% per annum decline in oil production. And we've been accomplishing that task just fine for the last 2.5 years, as the stats show.
Your talk about the scale of oil, gas and coal is just a red herring. Essentially, you are arguing like this:
1) We use mindboggling amounts of oil, gas and coal
2) Therefore we can't divert 1-2% per annum of oil use over to other power sources like electricity (generated by nuclear, wind, solar, coal, NG, tar sands, oilshale etc.)
There's no connection between 1) and 2). Can you please explain to me more clearly why 1) implies 2)?
