Germany has passed a series of laws over the past ~30 years under the umbrella of the Renewable Energy Act (EEG), and decade by decade, that's resulted in strong renewable energy growth in Germany: https://en.wikipedia.org/wiki/German_Renewable_Energy_Sources_Act https://en.wikipedia.org/wiki/German_Renewable_Energy_Source... Big energy projects of all kinds generally have at least a decade of preparation going into them before they come on-line. For solar and wind, this means everything from building more factories for solar PV and wind turbines, to devising and building better grid distribution systems, to incorporating large-scale storage into the system to account for intermittency.
