Everyone loves efficiencies. Combining generation technologies can create a plant that’s more than the sum of its parts, but engineering challenges mean these projects are not for the faint of heart. When you think of “hybrids” these days, your first thought is probably of automobiles. But hybrids—hybrid power plants, that is—are starting to emerge in […]

Worldwide, the U.S. is the largest producer of geothermal power; however, geothermal energy provides less than 0.5% of total generation in the U.S. Given geothermal’s small piece of the U.S. electricity pie

Geothermal resources have important strategic value for New Zealand, as they are able to directly supply both heat and electricity (see “New Zealand Geothermal Industry Is Poised for the Future” in this

Brine, the waste stream of the geothermal power production cycle, is usually considered a nuisance. High in corrosive minerals, even when reinjected, it’s challenging to manage. So when Simbol Inc. showed it had a way to turn this waste stream into a revenue stream by mining it for high-value minerals like lithium, a lot of […]

The U.S. Census Bureau released data on Nov. 18 showing that revenues for electric power generation industries that use renewable energy resources grew 49% from 2007 to 2012, while fossil fuel electric power generation industry revenues decreased 6.7% during the same time period. Fossil fuel revenues continued to dwarf renewable totals, bringing in $79.7 billion […]

This August, in a bid to bolster its latent geothermal energy industry, Indonesia passed new laws that allow geothermal exploration in protected areas such as forests. Located in the Ring of Fire—a string of volcanoes and fault lines around the Pacific Basin—the archipelago has estimated potential geothermal resources of up to 29 GW. State power […]

A new kind of geothermal power being developed by a team of scientists from the Lawrence Livermore National Laboratory (LLNL), the University of Minnesota, and the Ohio State University could sequester carbon

A new report from the National Renewable Energy Laboratory (NREL) suggests wind and solar generation could become cost-effective without federal subsidies if they are sited in the most productive locations. “It is too early to say how strong the post-2025 market for renewables will be or whether it will be primarily market-driven or policy-driven. In […]
