In this traditional state of Bavaria where election banners offering defense of “Heimat” (Homeland) seized the day in the last election, the posters wedged between ancient church domes on cobblestone streets now tout pictures of wind farms and slogans like “New Energy,” “For a clean environment and honest politics,” and “Economics and climate without crisis.” And that’s not just the placards from the pro-environment Green party. The conservative Christian Social Union (CSU), which has ruled the state uninterrupted since 1957, is now making affordable climate neutrality and renewables expansion a key part of its election platform.
