With currently only four drilling rigs active on geothermal projects in the U.S., this doesn´t provide a rosy picture for further geothermal growth in the U.S., despite the large number of projects.
In its monthly oil & gas drilling rig count, Baker Hughes provides an update on drilling rigs active in the North American and international markets. So while 2008 to 2010 saw some growth and stable number of rigs drilling on geothermal projects, the trend of 2011 and continuing into 2012 continues. It is a downward spiral.
No drilling means also no further growth in MW coming online.
