Drilling techniques originally developed to unlock oil and gas from shale formations are increasingly being adapted to access and extract heat from deep underground rock formations, enabling the generation of electricity from geothermal sources. And while geothermal’s share of total U.S. electricity generation remains quite small, it may be poised to accelerate, opening up new opportunities for companies in the oil and gas sector. In today’s RBN blog, we explain the basics of geothermal energy, its main advantages and drawbacks, and how U.S. expertise in oil and gas comes into play.
