The carbon dioxide intensity of U.S. energy supply (CO2 per unit of energy) in 2009 also dropped as a result of lower natural gas prices relative to coal.
There was also a slight increase in the CO2 intensity of U.S. energy supply (CO2 per unit of energy) in 2010, which is in contrast to a drop of 2.4% in 2009.

Given the lower per unit energy of natural gas, this expense would be recouped relatively quickly.
Currently, natural gas is about one-third the price of crude oil on a per unit energy basis.
Proponents point to the enormous energy density of the fuel (the amount of energy contained per unit).
It means that the only number consumers would have to compare between suppliers would be the unit energy charge.
Also, burning wood releases three times more carbon into the atmosphere than burning natural gas, per unit energy generated, said Booth.

Randall Jones, an economist at the OECD, notes that South Korea uses 1.5 times as much energy for every unit of GDP as does Japan.
In 2006 China set a target of a 20% cut by 2010 of its energy intensity (the amount of energy consumed per unit of GDP).
In 2006, the first year of the plan, the country's reduction in energy intensity, which measures energy consumption per unit of economic output, was a mere 1.23%.
In addition, according to the U.S. Energy Information Agency, the U.S. has reduced its energy consumption per unit of GDP by nearly 50% since 1980 and 20% since 1999.
Paul Tuohy is a researcher at Strathclyde University's Energy Systems Research Unit and he has made some calculations about how much we'd all save if politicians decided to act.
By roughly 2008, carbon microfilament capacitive storage devices were able to match the amount of energy stored per unit volume and per unit weight that chemical batteries were capable of.
Competitor GE Wind Energy, a unit of General Electric, ranked number one in wind turbines sales in the U.S. in 2009, according to a recent report from the American Wind Energy Association.
"They have little incentive to over-report use of energy, including electricity, as Beijing imposes increasingly restrictive regulations on energy use per unit of GDP on local governments, " said Bank of America Merrill-Lynch economist Lu Ting in a note.
WSJ: Some Economists Say China's Growth Has Slowed More than Data Suggest
That's partly due to the development of the capital markets over the past decade in places like India and Latin America, making it easier for a company to make long-term investments in those areas, says Colleen Harkness, a managing director with GE's Energy Financial Services unit.
Notable additions include natural gas company Spectra Energy, ranked 734, which was a former unit of Duke Energy, ranked 233.
But Prof David Elliott, co-director of the Energy and Environment Research Unit at the Open University, said a single barrage was "pretty hopeless" in energy provision terms as it would only produce power in two bursts during a 24-hour period.
To turn the ratio around: If you want to displace a unit of petroleum energy, you have to burn four-fifths of a unit in fossil fuels.
