Aliaksei Patonia writes: As one of the world’s least energy self-sufficient countries, Belarus has always been extremely reliant on the import of Russian oil and gas, which constitute around 90 percent of the nation’s primary energy supply. While oil is currently mostly refined for later export to the EU, natural gas serves as the main source of energy for Belarus’s electricity generation, household heating, and industries. Though the dependence on Russian gas has never been comfortable, its transit to Europe via the Yamal-Europe pipeline used to annually generate around $300 million for the national budget. Starting this year, however, the situation is likely to dramatically change. For the worse.
