[en] Large coal-fired power plants and severe air pollution are some of the most salient features in the Polish energy sector. Over 75% of the energy demand is covered by more than 100 million tonnes of coal per year. Natural gas only contributes 9%. However, it is expected that natural gas consumption will rise from 11.4 billion m³ in 1997 to 27 billion m³ in the year 2010. In addition emission standards will show some effect. At a 6% economic growth rate, emissions from the energy sector have not increased over the last few years
