This week in International Geothermal Opinion: Rethinking the investment risk

Giles Parkinson of the Australian, says that while geothermal energy is now characterized as unproven and thus “an over-the-horizon base-load technology,” by 2020, it might not just be cheaper than oil and gas and other competing base-loads such as carbon capture and nuclear, geothermal will also carry significantly less investment risk. “And if that’s not obvious now, taking into account the 10,000MW of geothermal energy currently produced across the globe, it will be crystal clear within the next two years.” You’ll need to go deep into the article – which begins with cows – to find this discussion. And look for a bit on heat exchanger technology that we are following up on.
