New Energy Sources: Possibilities and Prospects

January 18, 2013 by Mark Caine

Energy transition is not just an imperative: it’s a certainty. But while it’s certain that we’ll continue to transition towards a new energy mix, far less certain are the nature of this mix and the speed of our transition. Also uncertain, though certain to be profound, are the impacts of this transition on human societies and the economies and earth systems that sustain them.[read more]

Many different stakeholders have strongly supported the development and expansion of renewable power supply within the U.S. for many years. After 25 years of government and private support how much progress has actually been made towards replacing fossil fuels and nuclear power supply with renewable power sources? The answer may be surprising.[read more]

In a novel combination of carbon sequestration used in conjunction with geothermal power production, a South Dakota geothermal firm will use sequestered carbon dioxide instead of geothermal fluids to produce geothermal power.Rapid City-based Heat Mining Company can use the carbon dioxide captured in carbon capture and...[read more]

Geothermal Steams Forward, Under The Radar

April 16, 2012 by Nino Marchetti

Geothermal has long been touted as the only stable form of renewable energy because it produces constant 24-hour energy from hot rocks deep underneath the ground.Like the energy it produces, the geothermal industry is proving to be strong and steady as well. According to a recent Geothermal Energy Association (GEA) report, the industry...[read more]

Feed-in Tariffs Levy Larger Price Incentive for Clean Energy than European Emissions Trading Scheme

April 4, 2012 by Breakthrough Institute

Carbon-pricing advocates regularly point to European nations for examples of appropriate and effective clean energy deployment policies. Surging growth rates for solar and wind, coupled with regional declines in carbon emissions, are cited as clear vindications of Europe's Emissions Trading Scheme (ETS), the carbon-trading program that...[read more]

The ARPA-E Energy Innovation Summit is a wonderful collection of thinkers, policymakers, and industry leaders all focused on accelerating and spurring clean energy innovation. At the very least, we’re all trying to fundamentally change the U.S. energy sector.[read more]

Apply To The "Enhanced Geothermal Roadmap" Workshops

June 24, 2011 by Chris de Morsella

The Energy Efficiency and Renewable Energy agency (EERE) has announced a roadmap workshop for enhanced geothermal. It is inviting a select — small — group of subject matter experts to take part in this roadmap workshop in order to help develop a plan for how the country can proceed in developing its dry rock geothermal resources and...[read more]

In its latest quarterly financial report, Nevada Geothermal Power (CVX:NGP) states its revenue has increased more than 100%, while its net loss has been reduced by more than 75% compared to the same quarter last year. Currently, Nevada Geothermal Power's entire revenue stream comes from its Blue Mountain geothermal power plant in...[read more]

energyNOW! Video: Does Geothermal Power Cause Earthquakes?

May 9, 2011 by Silvio Marcacci

The Obama Administration betting big on enhanced geothermal systems, a new drilling technique that could boost geothermal power to 10 percent of America’s total portfolio. But it also could increase the risk of earthquakes. Correspondent Dan Goldstein goes to California and Oregon to investigate if this technique is shaky, or if it’s on solid ground.[read more]

A Geothermal Bankruptcy

I just caught up with last week's bankruptcy filing by Raser Technologies, Inc., a small developer of geothermal power plants. Burdened with excessive debt, Raser is filing for Chapter 11 protection to restructure its liabilities and continue operating under new ownership. In the process the current shareholders will see their much-...[read more]

Heating oil in Germany is currently more expensive than ever before at the beginning of a year. In this harsh winter, households that have already switched to renewable heating are in a financial advantage. In addition, heating systems based on renewable energy sources reduce the greenhouse gas emissions per kilowatt hour by up to 95...[read more]

We Don’t Need a Geothermal Portfolio Standard

By Gerard Prins, via Wikimedia Commons

The new Jan./Feb. 2011 issue of the Electricity Journal is now available, and it contains the usual range of interesting things to consider. Take, for instance, the article “Redefining Renewable Portfolio Standards: The Value of Installed Renewable Capacity.” The article observes, reasonably so, that some sources of renewable power can...[read more]

Sorry to nag, but about that geothermal power thing…

November 18, 2010 by Tyler Hamilton

Well, I’m at it again, sounding like a broken record, maybe, but it’s a song I have to play. My latest Clean Break column asks why Canada, and particularly Alberta, is still paying no attention to the potential of its geothermal resources while, south of the border, stimulus money is seeing geothermal power projects sprouting up and...[read more]

Hydrocarbons and Geothermal Energy

November 9, 2010 by Geoffrey Styles

Geothermal power is probably the lowest-profile renewable energy option we have. It doesn't get nearly the attention that wind and solar power do--even from me--although it has been quietly cranking out about 0.4% of the US electricity supply for many years. That roughly matches the expected output of all the wind turbines likely to be...[read more]
