The California Energy Commission (CEC) awarded $7.8 to two lithium recovery projects. Uniquely high concentrations of the dissolved soft metal are found in the brine produced by the state’s geothermal hotspots. The Salton Sea Known Geothermal Area contains an estimated six million tons of recoverable lithium within presently available geothermal... Read more →

The US Department of Energy (DOE) announced up to $5.5 million for 10 new projects to apply machine learning techniques to geothermal exploration and production. Machine learning—the use of advanced algorithms to identify patterns in and make inferences from data—could assist in finding and developing new geothermal resources. If applied... Read more →

The cost of generating power from renewable energy sources has reached parity or dropped below the cost of fossil fuels for many technologies in many parts of the world, according to a new report released by the International Renewable Energy Agency (IRENA). The report, “Renewable Power Generation Costs in 2014”,... Read more →

The California Energy Commission approved nearly $18 million to fund projects that will help the state meet its climate and energy goals. Twelve million dollars will go toward three alternative fuel projects, $4 million will help fund two geothermal projects and $3.5 million will help fund local energy efficiency projects....
