Nuclear Is Still the Lowest Cost Option, says IEA/NEA Report

Nuclear costs aren’t on the rise globally as has been widely thought, says a new report from the International Energy Agency (IEA) and Nuclear Energy Agency (NEA) surveying the levelized cost of generating electricity (LCOE).  The eighth edition of the report, “Projected Costs of Generating Electricity” compiles data for 181 plants in 19 OECD and […]

In order to achieve its goals for the future, the power sector in Turkey will need to leave the past behind. Download a pdf of this sponsored report by Global Business Reports. Power in Turkey (Global Business Reports, 2015)

Kenya Banks on Geothermal for Majority of Its Power

After adding a 280-MW geothermal power complex to its grid last year, Kenya is producing most of its power from geothermal sources, says the state-owned Kenya Electricity Generating Co. (KenGen). This February, the East African country formally inaugurated the last phase of the Olkaria geothermal power complex, which comprised the 140-MW Olkaria IV plant and […]

Leveraging Generation Synergies with Hybrid Plants

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 […]

Mining for Lithium in Geothermal Brine: Promising but Pricey

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

Mining for Lithium in Geothermal Brine: Promising but Pricey

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 […]

Power Sector Fossil Fuel Revenues Decrease While Renewable Energy Grows Rapidly

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 […]

Indonesia Law Seeks to Allow Development of Volcano Power

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 […]
