Working natural gas storage capacity grows 3% year-over-year
EIA estimates that the demonstrated peak working gas capacity for underground storage in the lower 48 states rose 3%, or 136 billion cubic feet (Bcf), to 4,239 Bcf in 2012 compared with 2011. EIA's report compares data from April to April; since April 2012, EIA analysts said 7.5 Bcf has been added to working gas storage capacity cited in the report, and they estimated that another 32 Bcf could potentially be added by year-end.
Demonstrated peak capacity is the aggregate peaks for a rolling five-year period of what storage operators actually put in the ground. It differs from design, or engineered, capacity (a larger volume), which is what the nation's storage facilities could physically hold. The demonstrated peak volume is what typically is considered a proxy for full storage.

Pad drilling and rig mobility lead to more efficient drilling
Note: Three-dimensional representation of oil or natural gas development of a large underground area, from four drilling pads on the surface (depicted within the red ovals).
Developments in drilling methods and technology are leading to efficiency gains for oil and natural gas producers. For example, "pad" drilling techniques allow rig operators to drill groups of wells more efficiently, because improved rig mobility reduces the time it takes to move from one well location to the next, while reducing the overall surface footprint. A drilling pad is a location which houses the wellheads for a number of horizontally drilled wells. The benefit of a drilling pad is that operators can drill multiple wells in a shorter time than they might with just one well per site.

Energy-related carbon dioxide emissions down in 2011
Download CSV Data
Annual energy-related carbon dioxide (CO2) emissions fell 2.4% in 2011 compared to the level in 2010. Several factors combined to produce this drop, including slower economic growth, weather, and changes in the prices of fuels, which played out differently in major economic sectors. Energy-related carbon dioxide emissions have declined in the United States in four out of the last six years.

Natural gas demand at power plants was high in summer 2012
Natural gas use for power generation rose this summer because of hot-weather-driven electricity demand for air conditioning coupled with low natural gas prices. According to Bentek Energy, estimated daily natural gas use to produce electric power (also called power burn) averaged 26.3 billion cubic feet per day (Bcf/d) so far in 2012 (Jan 1 - Aug 15), up 24% compared to the same period for 2011. Bentek Energy, which has been estimating power burn since January 2005, said that 17 of the 25 highest days of power burn since 2005 occurred this summer between June 28 and August 9.

NRG-GenOn acquisition plan would create the largest independent power producer
In late July 2012, the electric power company NRG announced plans to acquire GenOn, another independent power producer with assets in some shared markets, which would create a new company with 47 gigawatts of capacity in 21 states. The combined company would be the largest independent power producer in the United States, although the acquisition is still pending approval.

Strait of Hormuz is chokepoint for 20% of world’s oil
International crude oil and liquefied fuels movements depend on reliable transport through key chokepoints. In 2011, total world crude oil and liquefied fuels consumption amounted to approximately 88 million barrels per day (bbl/d), and more than one-half was moved by tankers on fixed maritime routes. Chokepoints are narrow channels along widely used global sea routes, some so narrow that restrictions are placed on the size of the vessel that can navigate through them. The map shows chokepoints that are critical areas for global energy security because of the high volume of oil that moves through waterways.

Electric grid operators monitoring drought conditions
Note: All data are preliminary and subject to revision. Final data will be published later this fall. Only power plants that reported operational cooling systems that withdrew water for cooling in 2011 are displayed. Cooling systems are aggregated to the plant level.
Prolonged drought can affect power plants that rely on large volumes of fresh water for a variety of reasons. Though there have been few reported problems this year, lower water levels are a potential concern for grid operators and system planners during periods of extended drought.

Drought increases price of corn, reduces profits to ethanol producers
Drought conditions in Midwestern states have reduced expectations for the amount of corn that may be harvested in 2012, and contributed to a 35% rise in the price of corn from June 18 to August 29. During the same time period, the spread between ethanol and corn prices (known as the 'crush spread') declined by $0.22 dollars per gallon.

Drought has significant effect on corn crop condition, projected ethanol production
The U.S. Department of Agriculture (USDA) has reported a significant rise in the proportion of poor and very poor corn crops this summer, due largely to the extreme drought across much of the center of the nation. The corn crop in the affected region is a main feedstock for ethanol, which is blended into gasoline.

Hurricane Isaac affects U.S. Gulf Coast energy infrastructure
Hurricane Isaac is a category one hurricane, significantly less severe than Hurricanes Katrina, Rita, Gustav, and Ike in 2005 and 2008, but it has affected Gulf Coast energy infrastructure. The slow-moving but large hurricane with sustained winds of 80 miles per hour made landfall at 6:45 p.m. Central Time Tuesday along the coastline of southern Louisiana. Federal emergency officials believe that these characteristics of the storm suggest that flooding from rainfall is likely to pose larger risks than wind.
The National Oceanic and Atmospheric Administration (NOAA) predicted a near-normal Atlantic hurricane season this year.
