According to a new report, the total carbon dioxide emissions in the United States energy sector rose 2 per cent in 2013.

The federal energy officials reported Monday showed that emissions form the nation's energy sector increased about 2 per cent in 2013 after recording a fall for several years.  The U. S.  Energy Information Administration, the analytical branch of the Department of Energy said that the emissions increased as power plants burned up more coal to generate electricity after several years in which natural gas recorded an increasing share of the nation's electricity.

The agency said in an online report that the report is not finalised yet but analysts expect a 2% increase in carbon emissions over 2012 due to an increase in the consumption of coal in the country.  Power plants are the biggest source of greenhouse gases that cause climate change.  Carbon dioxide emissions from domestic power generation rose to its highest level since 2007 and have declined four out of the six years since.  The fall is partially due to a fall in the demand for energy in the US economy.  The energy administration had earlier warned of the 2013 increase in carbon emissions.
