Germany has vast financial resources at its disposal. They could go on a natural gas plant building binge and link deals to the US on imports for long durations that the US would be thrilled to do. That would help narrow the trade deficit Germany has with the US ($65 billion annually; natural gas trade could solidly knock out half of that), so killing two birds with one stone. With help from the US abundance of natural gas supply, Germany could replace half its coal power in the next ~15 years using natural gas and significantly reduce its CO2 output just from that (and a big chunk of the other half could probably be knocked out by gradual renewable growth from where they're already at).
