Iberdrola’s global strategy to close its remaining coal-fired power plants has met with government opposition in its home country of Spain. Days after Iberdrola, the country’s largest utility, said it

In the next 25 years, the world will turn increasingly to renewables and natural gas to meet energy demand, turning away from coal, according to the International Energy Agency’s (IEA’s) World Energy

Moving toward sustainable manufacture of photovoltaics, Dr. Manuela Schiek’s research group in Oldenburg, Germany, has discovered how the latest technology in confocal laser scanning microscopy is enhancing both accuracy and efficiency of their research into organic semiconductors and transparent electrodes. Harvesting energy directly from the sun in order to generate electricity, solar cells appear to […]

A Michigan utility will build a $500 million natural gas-fired power plant on the site of an existing coal-fired plant in Lansing, and plans to retire the coal plant and another coal-fired facility in the town in the next few years. Lansing’s Board of Water & Light (BWL) announced the project December 18. The city-owned […]

A utility group on December 18 agreed to keep a coal-fired power plant in Colorado Springs, Colorado, open for at least a few more years, and its members said they are prepared to move forward with distributed generation and could import power to make up for the eventual retirement of the Martin Drake Power Plant. […]

Aquila Capital has acquired Project Valhalla, one of the largest wind farm projects in Europe. The project will consist of 85 of the latest V136 4.2 MW Vestas turbines and thus have an installed capacity of 357 MW with an energy output of more than 1.1 TW when it is completed. It is located on […]

In Gaildorf, the first part of the pilot project for natural-energy storage supplies green energy with immediate effect. It starts with four wind turbines, which will produce wind power with a total nominal output of 13.6 MW. Another 16 MW from the integrated pumped storage power plant will be added at the end of 2018. […]

Oman recently began operating a Wärtsilä-built power plant in the northern part of the country, part of more than $1 billion in power and energy projects being developed in the Arab nation. The Musandam Independent Power Project (IPP) is a 120-MW natural gas-fired plant (Figure 1) that can use light fuel oil as a secondary […]

A report released December 14 by the North American Electric Reliability Corp. (NERC) says power generation from natural gas-fired units and renewable sources such as solar and wind will provide enough electricity to offset the closures of U.S. coal-fired and nuclear power plants in the next decade. The agency’s 10-year outlook, part of its 2017 […]

Supercritical carbon dioxide (sCO2) cycles—which are inching closer to commercial applications for waste heat recovery, concentrating solar power, nuclear, and fossil energy—offer higher thermal efficiencies and power density than conventional steam Rankine and Air Brayton cycles in use today for power generation. But to realize these potentially game-changing cycles, common challenges associated with turbomachinery must […]
