Since the first industrial revolution, Silesia was an important and highly contested territory among the central empires. His wealth of raw materials and deposits of coal could shift the balance of power.

Much time has passed since that period. Today Silesia, a Polish voivodeship, is a region with an uncertain future. Heavy industry has been in decline for decades, coal deposits are running out, unemployment is rampant.

Citizens are still heavily dependent on the coal supply chain and strongly reluctant to convert to more sustainable energy supplies.

During the winter, Silesia records a concentration of dust under the air.
