The Czech Republic is reducing its dependence on highly polluting low-grade brown coal as a source of energy. Natural gas is procured from Russian Gazprom, roughly three-fourths of domestic consumption, and from Norwegian companies, which make up most of the remaining one-fourth. Russian gas is imported via Ukraine, Norwegian gas is transported through Germany. Gas consumption (approx. 100 TWh in 2003–2005) is almost double electricity consumption. South Moravia has small oil and gas deposits.
