Why it accelerated
The power market is not new, yet cost, policy, and demand aligned in one window. A repeated driver is validating small steps before promotion, because fitting daily use matters more than being cutting edge for its own sake and optics.

A practical lens Judge any direction by maturity, local resource match, cost-standards fit, and daily impact. Keep patience with real constraints and favor maturity over slogans, because the market rewards those who deliver steadily more than those who merely announce loudly.
