US Energy Production Outpacing Consumption

Print Friendly
[Editor's notes at the end.]
The US Energy Information Administration has just released its “Annual Energy Outlook 2013
” report with projections for US energy markets through to 2040. The report shows that growth in the country’s energy production is outpacing the growth of consumption.
Specifically, the report found that the growth of renewable energy is much faster than the use of fossil fuel.

“EIA’s updated Reference case shows how evolving consumer preferences, improved technology, and economic changes are pushing the nation toward more domestic energy production, greater vehicle efficiency, greater use of clean energy and reduced energy imports,” said EIA Administrator Adam Sieminski. “This combination has markedly reduced projected energy-related carbon dioxide emissions.”
Some key findings:

Crude oil production, particularly from tight oil plays, rises sharply over the next decade. The advent and continuing improvement of advanced crude oil production technologies continues to increase projected domestic supply. Domestic production of crude oil increases sharply in AEO2013, with an annual growth averaging 234 thousand barrels per day (bpd) from 2011 through 2019, when production reaches 7.5 million bpd (Figure 1). The growth results largely from a significant increase in onshore crude oil production, particularly from shale and other tight formations. After about 2020, production begins declining gradually to 6.1 million bpd in 2040 as producers develop sweet spots first and then move to less productive or less profitable drilling areas.Motor gasoline consumption is lower in the AEO2013 relative to the level in AEO2012, reflecting the introduction of more stringent corporate average fuel economy (CAFE) standards; growth in diesel fuel consumption is moderated by increased use of natural gas in heavy-duty vehicles. AEO2013 incorporates the greenhouse gas (GHG) and CAFE standards for light-duty vehicles (LDVs) through the 2025 model year, which raise the new vehicle fuel economy requirement from 32.6 miles per gallon (mpg) in 2011 to 47.3 mpg in 2025. The increase in vehicle efficiency reduces gasoline use in the transportation sector by 0.5 million bpd in 2025 and by 1.0 million bpd in 2035 in AEO2013 compared to the AEO2012 Reference case (Figure 2). Furthermore, the improved economics of natural gas results in an increase in the use of liquefied natural gas (LNG) in heavy-duty vehicles that offsets a portion of diesel fuel consumption. The use of petroleum-based diesel fuel is also reduced by the increased use of diesel produced using gas-to-liquids (GTL) technology. Natural gas use in vehicles reaches 1.7 trillion cubic feet (including GTL) by 2040, displacing 0.7 million bpd of other motor fuels. 

The United States becomes a larger exporter of natural gas than projected in the AEO2012 Reference case. US natural gas production increases throughout the projection period (Figure 3), outpacing domestic consumption by 2020 and spurring net exports of natural gas. Higher volumes of shale gas production in AEO2013 are central to higher production volumes and an earlier transition to net exports than was projected in the AEO2012 Reference case. US exports of LNG from domestic sources rise to approximately 1.6 trillion cubic feet in 2027, double the 0.8 trillion cubic feet projected in AEO2012; the United States becomes a net exporter of LNG in 2016

Renewable fuel use grows at a much faster rate than fossil fuel use. The share of electricity generation from renewables grows from 13 percent in 2011 to 16 percent in 2040. Electricity generation from solar and, to a lesser degree, wind energy sources grows as recent cost declines make them more economical. However, the AEO2013 projection is less optimistic about the ability of advanced biofuels to capture a rapidly growing share of the liquid fuels market than AEO2012. As a result, biomass use in AEO2013 totals 4.2 quadrillion Btu by 2035 (compared to 5.4 quadrillion Btu in AEO2012) and 4.9 quadrillion Btu in 2040, up from 2.7 quadrillion Btu in 2011.With improved efficiency of energy use and a shift away from the most carbon-intensive fuels US energy-related carbon dioxide (CO2) emissions remain more than 5 percent below their 2005 level through 2040 [Editor's note: recall, from our post moments ago, that "energy-related carbon dioxide (CO2) emissions" is a very deceiving term that hides simultaneous growth in CO2 emissions from natural gas flaring, among other things].

The projected growth rate for US energy-related CO2 emissions has declined successively in each Annual Energy Outlook since AEO2005, reflecting both market and policy drivers (Figure 4). Emissions from motor gasoline demand in AEO2013 are lower than in AEO2012 as a result of the adoption of fuel economy standards, biofuel mandates, and shifts in consumer behavior. Emissions from coal use in the generation of electricity are lower as power generation shifts from coal to lower-carbon fuels, including natural gas and renewables. The story is somewhat more complex for natural gas. Emissions from natural gas use are higher in the industrial and electric power sectors in AEO2013 than in AEO2012 as a result of increased consumption; however, the increase is partially offset by lower emissions from natural gas use in the residential and commercial sectors in AEO2013 as a result of the implementation of efficiency standards for energy-using equipment and other changes that affect demand.

Other AEO2013
 Reference case highlights:The Brent spot crude oil price declines from $111 per barrel (in 2011 dollars) in 2011 to $96 per barrel in 2015. After 2015, the Brent price increases, reaching $163 per barrel in 2040, as growing demand leads to the development of more costly resources. World liquids consumption grows from 88 million bpd in 2011 to 113 million bpd in 2040, driven by demand in China, India, Brazil, and other developing economies.Total US primary energy consumption grows by 7 percent in the AEO2013 Reference case, from 98 quadrillion Btu in 2011 to 108 quadrillion Btu in 2040. The fossil fuel share of primary energy consumption falls from 82 percent in 2011 to 78 percent in 2040 as consumption of petroleum-based liquid fuels falls, largely because of the incorporation of new fuel efficiency standards for LDVs.In the AEO2013 Reference case, energy use per capita declines by 15 percent from 2011 through 2040 as a result of improving energy efficiency (e.g., new appliance standards and CAFE) and changes in the way energy is used in the US economy. Energy use per 2005 dollar of gross domestic product (GDP) declines by 46 percent from 2011 to 2040 in AEO2013 as a result of a continued shift from manufacturing to services (and, even within manufacturing, to less energy-intensive manufacturing industries), rising energy prices, and the adoption of policies that promote energy efficiency. CO2 emissions per 2005 dollar of GDP have historically tracked closely with energy use per dollar of GDP. In the AEO2013 Reference case, however, as lower-carbon fuels account for a bigger share of total energy use, CO2 emissions per 2005 dollar of GDP decline more rapidly than energy use per 2005 dollar of GDP, falling by 56 percent from 2005 to 2040, at an annual rate of 2.3 percent.Net imports of energy decline both in absolute terms and as a share of total US energy consumption. The decline in energy imports reflects increased domestic petroleum and natural gas production, increased use of biofuels, and lower demand resulting from rising energy prices and the adoption of new efficiency standards for vehicles. The net import share of total US energy consumption is 9 percent in 2040, compared with 19 percent in 2011. (The share was 29 percent in 2007.)

[Editor's notes: There's a lot of data above, and I'm sure much of it is confusing to the average reader. So, I'm just going to pull out a few underlying points and add some of my own:

It's pretty clear that the EIA is predicting a huge natural gas boom, not just in the coming years, but the coming decades. Whether or not this will come about is unclear, but that's the track we are currently on. The EIA is quite 'biased' in its energy projections because it gives a lot of credence to what has been happening in the past year, what is happening at the moment, and not so much what is likely to happen as wind and solar policies and innovation make them more and more attractive from a financial perspective.Natural gas is arguably much better than coal or oil. However, several researchers have also put up huge red flags regarding methane leaks and the true result of natural gas flaring, red flags which imply natural gas may not be so much better after all, and may not be better at all in a worst case scenario.The projected increase of renewable electricity from 13 percent in 2011 to 16 percent in 2040 seems like a joke. If we had that small of an increase in that time, I'd be shocked. I'd bet all my savings that projection is way off. And, again, it's a result of the EIA's narrow approach to making these projections. However, it is based on something -- a US Congress that has been completely horrid at doing what the public wants, which is climate action and a strong promotion of renewable energy production. Let's hope we don't stick in a grid-locked Congress and society on this matter for long... and certainly not as long as the EIA is projecting!
Those are my main thought chime in with your own if you have them.]

Smart phones power consumption cut by more than 70 percent

ScienceDaily (Nov. 25, 2011) — Researchers at Aalto University in Finland have designed a network proxy that can cut the power consumption of 3G smart phones up to 74 percent. This device enhances performance and significantly reduces power usage by serving as a middleman for mobile devices to connect to the Internet and handling the majority of the data transfer for the smart phone. Historically, the high energy requirements of mobile phones have slowed the adoption of mobile Internet services in developing countries.


-- This new solution is particularly valuable in developing countries because it provides significantly more effective Internet access to a much larger number of people. At the moment, only a small percent can access the Internet from a wired connection, but 90 percent of the African population lives in areas with mobile phone network coverage. Mobile phone usage is increasing rapidly, however the use of mobile Internet services is hindered by users not having access to the power grid to recharge their phones," says Professor Jukka Manner from Aalto University.


The case study conducted at Aalto University examined Internet usage in three East African countries: Tanzania, Uganda and Kenya. Researchers developed energy-saving solutions for smart phones that could be easily deployed across a mobile network and in particular in areas without reliable sources of electricity. In addition to the new, optimized proxy solution, the researchers found that the power consumption of smart phones could also be significantly reduced by mobile optimized websites, HTTP compression and more efficient use of data caching.


The study was published at the scientific conference Africomm 2011. The research began in the Future Internet research program of TIVIT and funded by Tekes -- the Finnish Funding Agency for Technology and Innovation. The work has been continued in the ECEWA project funded by Tekes, with partners from European Communications Engineering Ltd, Efore Plc, Ericsson, Aalto University and Tampere University of Technology.

Reduce consumption electric Intelligy

The advantages of the technological progress in the world of energy mean that many of these implementations revolve around an energy saving, which is not only an economic advantage, but a matter of State, that benefited long-term in alleviating the energy deficit that has a particular population, if the intakes are lower.

On this occasion, we have encountered with the presentation of a named device as Intelligy, that as his name is indicating, it is pointed to an intelligent consumption of energy power, easy to use and that will allow us to manage the spending power of a home, Office or any environment.

Of course, this requires an entire infrastructure, with electronic devices that connect wirelessly with this invention, which has the mission to simply monitor how much consumed in periodically, weekly or monthly, and assess a proposal for the user to consume less electricity.


It is easily controllable with a touch screen and a simple, intuitive GUI also scheduled to give an alert when we forget a device is switched on or when we're doing an unnecessary expense.

Malaga: Consumption energy controlled from home

A group of researchers from the Foundation Habitec (Parque Tecnológico de Andalucía) in Malaga, are working in the European project EnergyTIC. This is to develop a System of communication that allow each household to know--and thus take away a better control - your energy consumption. To do this they are launching a pilot test in 700 housing where users through internet or TDT will receive information on the amount of electricity and water use.

Not only you can see own electricity and water consumption , also can compare with the values of other individual or communities. Also provide other information that will enable known parameters that we are not doing a proper use of resources, and advice to do so in a way more efficient. An example: how much of the amount of our invoice for the electrical service corresponds to appliances left in standby (may be 12% of our total expenditure).


The initial phase will begin in March and April and will have a duration of three years. There will also be another similar experience in France and - probably - in the Netherlands.
