Geothermal exploration permits on offer in Nothern Territory  

The ABC has a report on an upcoming Northern Territory geothermal energy permit offering (noting that as the Territory isn't connected to the national grid, initial scope for large scale production is limited) - Geothermal exploration permits on offer.

A geothermal energy analyst expects the Northern Territory's hot rocks will attract a lot of interest from resources companies. Applications for geothermal energy exploration permits open today when the Geothermal Energy Act comes into effect.

Research suggests at least two thirds of the Territory has higher than average heat flow below the surface.

Geothermal analyst Greame Beardsmore says that means there is potential for renewable power production from hot rocks. "I know certainly of two companies and I've heard rumours of several more that do intend to lodge applications," Mr Beardsmore said.

Internet search giant Google Inc. (GOOG) plans to invest directly in one or more renewable energy projects as part of a broader move to expand investment in clean -energy technology, a company executive said Monday. "It's a logical step from technology investing," said Dan Reicher, director of climate and energy initiatives.

Google issued a 20-year energy proposal last year that encourages greater use of conservation and renewable energy to combat climate change, and earlier this year the company released online software called Google PowerMeter that helps consumers track their home energy use.

Google.org, the company's venture capital and "philanthropic" arm, has invested in two next-generation geothermal power startups. But aside from those investments, an internal energy-efficiency initiative and hints it is eyeing the nascent U.S. smart-grid market, Google has generally stayed on the sidelines of the energy markets.
