When reading forecasts tied to percent rates of this and that, it’s well to keep in mind that extending them too far into the future – no matter that they have been valid for several years past – is to presume a continuity of circumstances that never holds for any great length of time. How about the not-so-long-ago projections for the continuing growth of utilities? Or natural gas, gasoline and oil consumption? Forecasts that run way out are invariably way off.
