Abstract Entrepreneurs are looking for ways to drill deeper, cheaper, and more successfully than before by borrowing methods honed by the oil and gas industry. These startups are bringing enhanced geothermal power systems online that promise sustainable, zero-carbon electricity that is not dependent on the time of day or the local weather. The hope is that by capitalizing on more than a century of petroleum-industry expertise, geothermal wells can operate reliably and relatively inexpensively well into the next century.
