It's hot on the ground in New Mexico, but it's the heat underneath that's attracting new attention. A former Los Alamos National Laboratory researcher is calling for a new look at a way of doing geothermal that avoids causing seismic activity.
In the past, there have been questions about whether existing geothermal drilling techniques could trigger earthquakes, reports Richard Snodgrass of the Los Alamos Monitor in a story picked up by the Associated Press.
Other forms of renewable energy, including biomass, solar and hydrogen, have attracted more attention from researchers and investors, but this year the U.S. Department of Energy is taking a closer look at "hot dry rock" geothermal potential.
