Cities in eastern and central China have begun rationing power resources following a period of extreme cold that has led to a strong increase in energy demand.

Many of the nation’s manufacturing and farming areas have experienced snow, sleet and unusual cold, which has led authorities to begin rationing power for industry and urging residents to limit gas use.

According to reports the extreme weather conditions have seen energy demand escalate, while weakened transport networks have slowed coal supplies.

It is feared that if conditions worsen, power cuts could occur and production in economic provinces could be affected.
