TRL 3: Experimental Proof of Concept

This dimension marks how mature a specific energy technology actually is, experimental, emerging or fully commercial. Wikipedia notes that "in some geographic localities, photovoltaic solar or onshore wind is the cheapest new-build electricity," a sign of just how mature those particular technologies have become. Browsing by maturity separates technologies still emerging from those already fully commercial.
