I have heard several things today through various media, including this blog post: http://www.nofrackingway.us/2014/04/22/kerrys-shale-gas-bluff/ about the situation with Ukraine in regards to the dangers of losing access to Russian methane.
If the US really wants to help Ukraine and other European countries get out from under the thumb of Russian fossil fuel threats, it should help them quickly implement alternate energy sources, especially renewable ones. Help fund a transition to geothermal heat pumps for heating and cooling. Find appropriate sites for solar and wind electrical production. Local, distributed energy systems will increase economic well-being and alleviate the fear of Russia cutting off Ukraine and, by extension, much of the rest of Europe from methane for heating during the winter.
Earth Day bonus: It would be a huge help to the climate as we urgently need to stop burning fossil fuels as soon as possible.
