The world is a lot bigger than the US and they've all followed pretty much the same trajectory the last two decades. A slow long term investment in R&D/manufacturing techniques, followed by increased adoption when it became economically competitive. Combined with varying levels of government incentives and measured regulation, to ease transitions so it doesn't destroy the economy which we still depend on for everything else.

These major shifts always happen slowly then start exponentially growing once it's demonstrated to be practical.
