Natural gas is used mainly in Russia, which accounts for about 98% of our total use of natural gas. Natural gas is used in small quantities also in Finland, the Baltic countries and Poland. The world's natural gas reserves are big, and there is enough natural gas for energy production demand for several decades.
Natural gas is the cleanest of the fossil fuels in terms of greenhouse gases and other flue-gas missions with relations to produced energy, therefore it doesn't contain sulphur and generates only minimal particle emissions. Nitrogen oxide emissions can be decreased with combustion technology. Potential leaks from gas pipelines have an impact on the climate because natural gas is almost 100% methane, which is a greenhouse gas worse than carbon dioxide.
Coal accounts for about 10% of Fortum's energy sources. About half of this is used in Russia and the other half in Finland and Poland. Coal's availability and storability make it an economical source for reserve and peak-lead power; in some situations, it is the only viable alternative.
