From about 1973, electricity usage was roughly evenly split between residential, commercial and industrial. The annual, seasonal, high-low demand cycles (winter-summer) can be readily seen in residential and commercial demand, both widening with teh advance of time and increased usage of airconditioning and or heating. There is also some more limited annual cyclicity in industrial demand.
The impact of recessions in 1975 and 1982, on industrial demand, can be seen followed by a return to growth. However upon the 2000 ‘Tech crash’ industrial demand dropped but thereafter growth did not resume. Was the industrial growth effectively ‘exported’ or outsourced to other countries? A similar effect is seen upon the 2008/09 ‘global financial crisis’.
It also appears that since early 2017, that USA industrial demand on electricity may be declining further.
The USA is an advanced economy, with about 70% of GDP reliant on consumer spending, and services industries making up a significant part of GDP. We have also noted that USA’s direct consumption of raw materials has, over time, since about the 1980’s declined from circa 20% of global commodities to roughly 5-7% today, as it tends to import finished goods, more than manufacture them domestically, i.e. exporting the manufacturing function to lower cost jurisdictions.
Matau will be watching the apparent new trend from early 2017.
