A proposed geothermal project in Iceland will produce electricity that will be transmitted to Britain via a undersea cable. The electricity is expected to be cost competitive.

Geothermal Gradients in New Hampshire
November 9, 2012 | USGS

“The U.S. Geological Survey, in cooperation with the New Hampshire Geological Survey, measured the fluid temperature of groundwater in deep bedrock wells in the State of New Hampshire in order to characterize geothermal gradients in bedrock.” Quoted from the USGS press release.

Is Geothermal Stormproof?
November 7, 2012 | New York Times

An article in the New York Times explains how Hurricane Sandy has some building owners considering geothermal energy as a “stormproof” heating and cooling system.

The Future of Emissions in Australia
October 9, 2012 | National Geographic News

Fossil fuels play an enormous role in Australia’s economy. However, their roles will change significantly with new carbon taxes and a goal of cutting emissions to 80% below 2000 levels by 2050.

Subsidence and Geothermal Development
October 9, 2012 | USGS

“Recently, Hawaiian Volcano Observatory scientists have been asked if Hawaiʻi Island’s geothermal development causes subsidence of the ground surface, as has been observed at U.S. mainland geothermal areas, such as those in California—Coso, Geysers, the Imperial Valley, and Casa Diablo in the Mammoth Lakes area.”

New Geothermal Source in Utah
September 30, 2012 | Utah Geological Survey

“Discovery of a new type of geothermal energy resource in Utah offers hope for significantly more potential across the western U.S., and a boost in geothermal power production. [...] Preliminary results show that near-surface temperature gradients in the basin vary from about 60 degree C/km to 100 degree C/km. This implies temperatures of 150 to 250 degree C at 3 – 4 km depth beneath the basin. An abandoned oil exploration well drilled near Pavant Butte in the central part of the basin in 1981 confirms these exceptionally high temperatures.” Quoted from the Utah Geological Survey press release.
