Lower electricity-related CO2 emissions reflect lower carbon intensity and electricity use

U.S. energy-related carbon dioxide emissions (CO2) have declined in five of the past eight years. This trend has been led by emissions reductions in the electric power sector. Electricity demand growth has been lower than in the past and at the same time the power sector has become less carbon intensive (measured as CO2 emitted per kilowatthour of generation). Total emissions from the electric power sector in 2013 totaled 2,053 million metric tons (MMmt), about 15% below their 2005 level.

Weather-driven energy intensity increase led to higher energy-related emissions in 2013

Note: Growth rates reflect annual changes.

U.S. energy-related carbon dioxide (CO2) emissions increased in 2013 by 129 million metric tons (2.5%), the largest increase since 2010 and the fourth-largest increase since 1990. Emissions trends reflect a combination of economic factors (population multiplied by per capita output [GDP/population]), energy intensity (energy use per dollar of GDP), and carbon intensity (carbon emissions per unit of energy consumed).

Consumer energy expenditures are roughly 5% of disposable income, below long-term average

graph of consumer energy expenditures' share of disposable income, as explained in the article text
Source: U.S. Energy Information Administration, based on Bureau of Economic Analysis

Total U.S. household energy consumption expenditures have generally declined relative to disposable income since 1960, although during periods of high energy prices, consumers devote increasing shares of their income to energy. Energy expenditures ranged between 4% and 8% of disposable income since 1960. Consumer energy expenditures today are a lower percentage of disposable income than the average from 1960 to present (5.5% average).

North Dakota aims to reduce natural gas flaring

Source: U.S. Energy Information Administration, based on North Dakota Industrial Commission

About one-third of the natural gas North Dakota has produced in recent years has been flared rather than sold to customers or consumed on-site. The rapid growth in North Dakota oil production, which rose from more than 230,000 barrels per day (bbl/d) in January 2010 to more than 1,130,000 bbl/d in August 2014, has led to increased volumes of associated gas, or natural gas that comes from oil reservoirs. These increased volumes require additional infrastructure to gather, process, and transport gas volumes instead of flaring them. These additions can take time to build, and well operators are often reluctant to delay production. In an effort to reduce the amount of natural gas flared, North Dakota's Industrial Commission (NDIC) established targets that decrease the amount of flared gas over the next several years.

Energy for growing and harvesting crops is a large component of farm operating costs

graph of operating expense for various crops, as explained in the article text

The U.S. agriculture industry used nearly 800 trillion British thermal units (Btu) of energy in 2012, or about as much primary energy as the entire state of Utah. Agricultural energy consumption includes energy needed to grow and harvest crops and energy needed to grow livestock. Crop operations consume much more energy than livestock operations, and energy expenditures for crops account for a higher percentage of farm operating costs.

EIA launches expanded winter heating fuels data program for winter 2014-15

Note: Weekly heating oil prices are collected in the states shown in dark blue and in the District of Columbia, but not in Missouri, North Dakota, and South Dakota.

EIA is expanding the State Heating Oil and Propane Program (SHOPP) this winter heating season. SHOPP is a joint effort between EIA and participating states to collect weekly residential heating oil and propane price data. The SHOPP program has traditionally included 24 states in the Northeast and Midwest regions, but the program was expanded after many other states expressed interest in the program following the winter of 2013-14.

Some Appalachian natural gas spot prices are well below the Henry Hub national benchmark

Some natural gas prices at trading hubs in the Appalachian Basin's Marcellus Shale play are trading well below the national benchmark spot price at the Henry Hub in Louisiana. Over the past month, spot prices at many Appalachian hubs have dropped below $2 per million British thermal units (MMBtu) on days of low demand, while spot prices at Henry Hub and throughout much of the United States have traded near $4/MMBtu. However, prices at one Appalachian hub, the TCO Pool, which has the ability to back out deliveries from Gulf Coast sources and has pipeline connections that provide access to multiple markets, has maintained close parity to Henry Hub prices.

Newly released heat content data allow for state-to-state natural gas comparisons

The heat content of natural gas, or the amount of energy released when a volume of gas is burned, varies according to the extent that gases with higher heat content than methane are included in delivered gas. EIA is now publishing the heat content of end-use natural gas by state in the Natural Gas Monthly.

Net energy imports as share of consumption at lowest level in 29 years

Source: U.S. Energy Information Administration, Monthly Energy Review

Total U.S. net imports of energy as a share of energy consumption fell to their lowest level in 29 years for the first six months of 2014. Total energy consumption in the first six months of 2014 was 3% above consumption during the first six months of 2013, but consumption growth was outpaced by increases in total energy production. These changes led to a 17% reduction in net imports compared with the first six months of 2013.

Lower petrochemical use of propane driven by wider price spread between propane and ethane

Propane demand (measured as product supplied) is expected to be 100,000 barrels per day (bbl/d) lower on average in 2014 compared to 2013 because of reduced demand from petrochemical plants, according to EIA's Short-Term Energy Outlook. In contrast to propane used as a heating fuel in buildings during colder months and as a crop-drying fuel during the harvest season, both of which are highly seasonal and weather dependent, petrochemical consumption of propane has relatively little seasonality.
