Construction activity on wind projects across the U.S. surged to a record level of more than 20 GW in the third quarter of 2018, and about 35.1 GW of new wind capacity was under construction or in advanced development at the end of 2018, according to the American Wind Energy Association (AWEA).  In 2018, the […]

Cybersecurity firm FireEye has uncovered and is responding to a new intrusion at an unnamed critical infrastructure facility that it suggests in an April 10 blog post was perpetrated by the group behind the TRITON attack, which prompted a process shutdown at a Middle Eastern facility in 2017. But while details of the new attack are sparse, […]

Despite years of escalating natural disasters and dozens of reports examining the science and economic cost of climate change, the Green New Deal framework now languishes as a result of political backlash and its outsize ambition to remake the American economy. But dismissing the issue, and this opportunity, is unnecessary and dangerous.

Vogtle Electric Generating Plant’s Unit 2 in Georgia.  Nuclear giant Framatome delivered four GAIA lead fuel assemblies containing enhanced ATF (EATF), including both pellets and cladding, to the plant owned by Georgia Power in […]

RWE Generation’s Eemshaven power plant is the largest coal and biomass power plant in the Netherlands. Covered conveyor belts ensure dust-free transport of the coal from ships to the power plant or the storage yard. This process was always accompanied by jerks and jolts due to frequent belt mistracking. The constant downtime of the conveyor […]

Coal combustion was responsible for more than 0.3 degrees C of the 1-degree C surge in global average annual surface temperatures above pre-industrial levels—and that makes coal the single largest source of the global temperature increase, the International Energy Agency (IEA) says in a new report.  The finding, outlined in the IEA’s Global Energy & […]

The Department of Energy (DOE) unveiled a slate of measures to help U.S. hydropower thrive as costs for wind and solar plummet. Measures will include a roadmap to identify hydro’s value in a future grid, and a first-of-its-kind prize designed to encourage innovative and faster pumped storage construction techniques. In her opening speech at Waterpower […]

Florida Power & Light Co. (FPL) has been building new solar farms and bringing gigawatts of new natural gas-fired generation capacity online in recent years.
