The U.S. Fish and Wildlife Service (FWS) on December 14 finalized the latest version of its rule governing permitted levels of eagle deaths at wind turbine farms. The rule, first issued in 2009, governs the FWS’s administration of the Bald and Golden Eagle Protection Act, which makes it a criminal offense to kill or injure […]

In a finding that is likely to boost controversy over the future of U.S. energy policy, a comprehensive study of the full levelized cost of energy (LCOE) from various sources of electricity conducted by the University of Texas (UT) at Austin’s Energy Institute found that wind turbines and natural gas combined cycle power plants (CCPPs) […]

The entire state of South Australia suffered a blackout on the afternoon of September 28. The cause of the event has been disputed, but it has left Australians in a raging debate about the state of the country’s electricity system and policies that will shape its future power mix. The so-called “Black System” event that […]

Owner/operator: Pattern Energy Just as Seattle’s Amazon.com jumpstarted the online shopping trend, it’s now part of another trend that has major corporations owning or contracting for sizable grid-connected renewable power facilities. A new wind farm in rural Indiana is part of that story. Cloud computing is big business, and it’s growing as fast as cumulous […]

The world’s first wind farms are reaching the end of their expected lifetimes. As they become outdated, or just inefficient, many developers are considering repowering. Here’s a look at where repowering activity is happening the most and why. Since the world’s first wind turbine used to convert wind energy into electricity was built by Professor […]

The push for clean energy notwithstanding, no silver bullet can cure the challenges that our continued use of carbon engenders. Every form of energy production, green or black, clean or dirty, presents downsides. Siting an energy facility—whether clean energy, hydro, natural gas, coal or nuclear—inherently imposes some form of environmental harm. For renewables, one of […]

Global resources of variable renewable energy—primarily wind and solar—despite breakneck growth over the past two decades, are beginning to run up against technological and policy limitations on further deployment, and future growth will depend on significant changes in policy and grid design, according to a new report. Released on September 20, Variable Renewable Energy Sources […]

A strategy rolled out by the Department of Energy (DOE) and Department of the Interior (DOI) to enable 86 GW of offshore wind capacity in the U.S. by 2050 highlights a number of key hurdles, including those related to technology, regulations, the environment, and markets. The DOE’s and DOI’s September 9–released joint document, “National Offshore […]

If wind and solar photovoltaic (PV) penetrations in the Eastern Interconnection were amped up to 30%, they would decrease coal, combined cycle, and combustion turbine capacity factors by 30% to 50%, a new study from the National Renewable Energy Laboratory (NREL) suggests. The study, NREL’s Eastern Renewable Generation Integration Study (ERGIS), was released on August […]

It’s only 30 MW, but it’s a start. The Block Island Wind Farm, the first offshore wind farm in the U.S., completed installation of its five wind turbines in the waters off Rhode Island on Aug. 18 (Figure), setting the stage for full operations in a few weeks, owner Deepwater Wind said.     The […]
