OK, I like your thoughts, BUT....
.... a lot of previous recessions had nothing to do with the price of oil or energy. In fact, 19th century recessions were generally triggered by other things -- oil wasn't a thing yet, and they *weren't* triggered by coal shortages.
There are different types of recessions. Most of them are triggered by a shortage of money, as John Maynard Keynes explained. Most of these are simply high-interest-rate recessions. But some of these are more severe, "creditworthiness" recessions. This category includes 2008 and 1929, both of which featured critical events in which stuff which people thought of as "money" ("call money" in 1929, "money market funds" in 2008) were suddenly not thought of as "money" any more.
Some are triggered by shortage of a real good, such as oil -- this includes the 1970s stagflation.
A cleantech boom should be very similar to a 19th century industrial-revolution boom. The growth rates in these booms were generally limited by availability of labor. Or more rarely by availability of skilled labor. The latter might be the case again now. Each industry's boom would generally end with market saturation (i.e. everyone's got a washing machine), at which point the industry would become what we now consider a "cyclical" industry
The 19th century recessions were generally caused by a shortage of money; due to the Free Banking system, this happened a *lot*. (It happens less with the Federal Reserve.)
