Europe's deep winter freeze, partly due to the El Nino weather phenomenon, this year drove heating gas demand to a record high in Britain, and virtually disrupted gas supplies to Britain when needed the most.
As yet, the current winter in Britain is one of the coldest in the last 30 years.
However, the Meteorological office expects the winters to become increasingly warm and wet as a result of climate change.
Most climate scientists also say that the increase in carbon dioxide emissions, which began with the industrialisation of Europe in the 18th century, has had a warming effect on the world's climate.
According to some long-term forecasts, if current greenhouse gas emissions trends continue, global temperatures may be 4 degrees Celsius higher by the mid-2050s.
