Market changes contribute to growing Marcellus area spot natural gas trading (12/15/2011)
Marcellus-area spot natural gas trading (InterContinentalExchange day—ahead transactions) has more than doubled from under 1 billion cubic feet per day (Bcfd) to almost 2 Bcfd on average since 2005. Key factors likely contributing to increased natural gas spot trading in the Marcellus area include: rapid increases in Marcellus shale gas production; deliveries of Wyoming gas to the Ohio/Pennsylvania border through the Rockies Express Pipeline; and increased use of natural gas for power generation.

Wholesale Market Data (12/15/2011)
This site contains spreadsheets with wholesale electricity price data from ICE (IntercontinentalExchange) through December 9, 2011 (latest website update: December 15, 2011). The files contain peak prices, volumes, and the number of transactions at five electricity trading hubs covering most regions of the United States.

Congo (Brazzaville) Country Analysis Brief (12/14/2011)
Congo's (Brazzaville) oil production declined steadily for nearly a decade until 2008 when the country's first deepwater field came online. In 2010, output reached its highest level at 302,000 bbl/d, surpassing its previous peak in 2000 (292,000 bbl/d).

Electricity storage technologies can be used for energy management and power quality (12/14/2011)
Grid-scale energy storage technologies are currently limited in use but may see increased adoption in the future. A wide variety of technologies can serve an array of functions around the electric power system.

Energy & Financial Markets - What Drives Crude Oil Prices? (12/14/2011)
EIA has updated the "What drives oil prices?" website. This website assesses both physical and financial factors that could influence oil price movements.

Malaysia Country Analysis Brief (12/14/2011)
Malaysia is a significant oil and natural gas producer and is strategically located amid important routes for the seaborne energy trade. The countrys oil reserves are the third highest in the Asia-Pacific region after China and India. It was the worlds third largest exporter of liquefied natural gas after Qatar and Indonesia in 2010.

Most generator retirements over the past decade were older natural gas-fired units (12/13/2011)
The majority of total electric generator retirements (64%) from 2000 to 2010 were older, less efficient natural gas-fired units. Most retirements of natural gas capacity were steam turbines, which are considerably less efficient than the combined-cycle natural gas units that made up the majority of new capacity additions during the decade. Volatile commodity prices coupled with an excess supply of generation in the early part of the decade contributed to significant retirements in the fleet of natural gas-fired generators.

Smart Grid Legislative and Regulatory Policies and Case Studies (12/12/2011)
In recent years, a number of U.S. states have adopted or are considering smart grid related laws, regulations, and voluntary or mandatory requirements. At the same time, the number of smart grid pilot projects has been increasing rapidly. EIA commissioned SAIC to research the development of smart grid in the United States and abroad. The research produced several documents that will help guide EIA as it considers how best to track smart grid developments.

Electricity tends to flow south in North America (12/12/2011)
The map shows that electricity tends to flow south in North America. The numbers on the map reflect average net power flows (metered hourly) between electric systems aggregated by regions for the year 2010. Most electric power demand is served by local generators. Net interregional trade accounted for less than 1% of delivered power in 2010. However, excess, low-cost power, primarily from hydroelectric generators in the Pacific Northwest, Manitoba and Quebec, supplied higher-cost markets to the south.

Residual fuel consumption in the U.S. continues to decline (12/09/2011)
After reaching a high point of over three million barrels per day (bbl/d) in the late 1970s, demand for residual fuel oil in the United States has steadily declined (product supplied as seen in the chart below is a proxy for demand). Between 2000 and 2010, average annual residual fuel use fell from approximately 900,000 bbl/d to 500,000 bbl/d.

Natural Gas Year-in-Review (12/09/2011)
Natural gas production grew in 2010, with large gains in onshore production offsetting continuing declines in the Gulf of Mexico. Even as consumption grew year over year, particularly in the electric power and industrial sectors, strength in domestic production and abundant storage reduced the need for imports. Prices remained relatively low through the year.

What are renewable portfolio standards (RPS) and how do they affect renewable electricity generation? (12/08/2011)
Energy in Brief article discussing Renewable Portfolio Standards (RPS) and their impact on renewable electricity generation.

Gasoline with higher ethanol content getting closer to U.S. drivers' fuel tanks (12/08/2011)
U.S. gasoline blended with up to 15% ethanol by volume, known as E15, was approved as safe for use in all model year 2001 and newer vehicles by the Environmental Protection Agency at the beginning of 2011, but E15 gasoline still has several hurdles to clear before it can be sold at your local service station.
