If the goal is to reduce demand for Russian natural gas, the most cost-effective way is to do much more of what Germany and, to a lesser extent, the rest of the EU is already doing: promote conservation and mass transit and further subsidize the cost of installing solar and wind energy. That might not sound as hard-nosed as drilling everywhere, polluting groundwater and exposing people to the dangers of transporting a highly explosive fuel, but it is the solution that makes the most economic sense.
