Air conditioning accounts for about 12% of U.S. home energy expenditures

(Mon, 23 Jul 2018) Air-conditioning equipment is used in 87% of homes in the United States and, according to the latest EIA Residential Energy Consumption Survey (RECS), home air-conditioning costs averaged $265 in 2015, or 12% of total home energy expenditures. Air-conditioning costs ranged from an average of $525 in the hot-humid region in the Southeast to about $60 in the temperate marine region along the West Coast. The more moderate mixed-humid region, where home air-conditioning costs averaged $262, was closest to the national average.

Major utilities continue to increase spending on U.S. electric distribution systems

(Fri, 20 Jul 2018) Spending on electricity distribution systems by major U.S. electric utilities—representing about 70% of total U.S. electric load—has risen 54% over the past two decades, from $31 billion to $51 billion annually. This increase has been largely driven by increases in capital investment. From 1996 to 2017, annual capital investment by these utilities for electric distribution systems nearly doubled, which was similar to increases in transmission investment over the same time period.

Crossover utility vehicles overtake cars as the most popular light-duty vehicle type

(Thu, 19 Jul 2018) Trends in the sales shares of new light-duty vehicles by vehicle type have continued as the crossover utility vehicle (CUV) share of light-duty vehicles has increased, largely at the expense of cars, despite increases in gasoline prices over the previous two years. In each month since September 2017, sales of CUVs have exceeded those of cars, a class that includes sedans, hatchbacks, and sports cars.

Permian region natural gas prices fall as production continues to grow

(Wed, 18 Jul 2018) The natural gas spot price spread between the Permian Basin, as priced at the Waha Hub in western Texas, and the U.S. national benchmark Henry Hub in Louisiana has grown considerably in the past year. Natural gas prices at Waha are nearly a dollar per million British thermal units (MMBtu) lower than Henry Hub prices. This spread widened as the ability to transport the increased natural gas production in the Permian Basin in western Texas and southeastern New Mexico was constrained by existing pipeline capacity.

Volcanic lava flows continue to affect geothermal power generation on Hawaii’s Big Island

(Tue, 17 Jul 2018) Lava flows from the Kilauea volcano on the island of Hawaii led to the shutdown of the Puna Geothermal Venture (PGV) power plant on May 3, 2018. The 38-megawatt (MW) facility is the only geothermal plant on the island, and it produced about 29% of the island’s electricity generation in 2017. The plant voluntarily ceased operations ahead of the approaching lava flow.

U.S. refinery capacity virtually unchanged between 2017 and 2018

(Mon, 16 Jul 2018) As of January 1, 2018, U.S. operable atmospheric crude distillation capacity totaled 18.6 million barrels per calendar day (b/cd), a slight decrease of 0.1% since the beginning of 2017 according to EIA’s annual <em>Refinery Capacity Report</em>. Annual operable crude oil distillation unit (CDU) capacity had increased slightly in each of the five years before 2018.

South Korea Country Analysis Brief

(Mon, 16 Jul 2018) South Korea, which lacks domestic energy reserves, ranks among the world’s top five importers of liquefied natural gas, coal, and petroleum and other liquids. Despite its lack of resources, South Korea has some of the most advanced oil refineries in the world, and its companies have investments in overseas oil and natural gas assets.

The United States continues to export MTBE, mainly to Mexico, Chile, and Venezuela

(Fri, 13 Jul 2018) U.S. exports of methyl tert-butyl ether (MTBE), a motor gasoline additive, totaled 38,000 barrels per day (b/d) in 2017, primarily to Mexico, Chile, and Venezuela. MTBE was once commonly used in the United States but was phased out in the late 2000s as a result of water contamination concerns. Since then, fuel ethanol has replaced MTBE as a gasoline additive.

Wind generators’ cost declines reflect technology improvements and siting decisions

(Thu, 12 Jul 2018) Between 2010 and 2016, the capacity-weighted average cost (real 2016$) of U.S. wind installations declined by one-third, from $2,361 per kilowatt (kW) to $1,587/kW, based on analysis in the U.S. Department of Energy, Office of Energy Efficiency and Renewable Energy’s (DOE/EERE) <em>Wind Technology Market Report</em>. The reasons for this decline include improving technology and manufacturing capability and an increasing concentration of builds in the regions of the United States with the lowest installation costs.

Natural gas-fired electricity generation this summer expected to be near record high

(Wed, 11 Jul 2018) EIA’s July 2018 <em>Short-Term Energy Outlook</em> (STEO) expects natural gas-fired power plants to supply 37% of U.S. electricity generation this summer (June, July, and August), near the record-high natural gas-fired generation share in summer 2016. EIA forecasts the share of generation from coal-fired power plants will drop slightly to 30% in summer 2018, continuing a multi-year trend of lower coal-fired electricity generation.
