Why the Time Has Finally Come for Geothermal Energy

4 comments

1. Geothermal energy is essentially carbon-free, it is available at any time of day and in any weather, and it leaves a small footprint on the landscape. New approaches to harnessing it may have us on the cusp of an energy revolution. Rivka Galchen reports on the potential of geothermal energy.

2. I wonder what the effects of mass producing this on a global scale would be.

   Could it start to affect the temperature of the mantle and core?

   One or a hundred wells won’t make a difference, much like 1 or 100 cars won’t make a diffeeence to co2 in the climate.

   But at a global scale, things start to shift.

3. David Roberts with Volts recently had a fascinating interview podcast with the CEO of a geothermal company that is hoping to change everything about how we think about geothermal.

   They want to dig up to 5x (maybe more?) deeper than existing wells using microwave technology as the “drill” and then use superheated water.

   It’s an astonishing idea that hadn’t even been on my radar.

4. Finally come…..? We have been ready for geothermal for decades. Why has it taken so long to get put into wide use?
