Gen I and Gen II are typically used in high tech and wireless.

But how do they apply to energy?
Gen I Energy uses an energy resource "as is" with no increase to its natural intensity.

Gen I includes all fossil and non-hydro renewables.
Gen II Energy, dammed hydro or nuclear, increases the natural energy intensity.

Gen II technologies are highly disruptive.
Dammed hydro completely eliminated all undammed hydro generation.

Nuclear energy displaced 20% of fossil generation globally.
Gen I DE's such as rooftop solar and wind have high cost and very low intensity.

V 2 has the first low-cost high-intensity Gen II DE.
