Despite wind power’s going “mainstream,” original equipment manufacturers and end users struggle to pin down quality standards for ever-evolving wind turbine component technologies. As more utilities embrace wind power, the U.S. wind turbine market has expanded tremendously over the years. It has proliferated into numerous facilities that specialize in the roughly 8,000 component parts that […]

Broad, bipartisan energy legislation that would allocate federal funding to grid technology research and demonstration along with a number of other initiatives, including cybersecurity and the energy-water nexus, has cleared the Senate Energy and Natural Resources Committee with an 18–4 vote.  The committee’s chair, Sen. Lisa Murkowski (R-Alaska), and Ranking Member Sen. Maria Cantwell (D-Wash.) […]

With the Environmental Protection Agency (EPA) expected to issue its final rule on power plant greenhouse gas emissions under the administration’s Clean Power Plan (CPP) early next week, reports strongly suggest the revisions will extend compliance deadlines in response to power sector complaints about a too-aggressive schedule in the proposed rule. A July 28 report […]

Renewables giant SunEdison will acquire emerging distributed energy firm Vivint Solar’s 523-MW rooftop solar portfolio in a $2.2 billion acquisition deal that signals momentum for the business model that has challenged the bottom lines of traditional utilities. SunEdison and Vivint Solar signed a definitive merger agreement on July 20. It will involve the acquisition of Vivint […]

Interstate Power and Light (IPL) will be forced to spend $620 million to retire 10 coal-fired units and retire, refuel, or install pollution controls at several others in Iowa under a settlement reached with the federal government.  The Alliant Energy subsidiary has long anticipated the settlement announced on July 15 by the Environmental Protection Agency […]

In a report released this week, M.J. Bradley & Associates found that in 2013 power plant SO2 emissions were 80% lower and NOx emissions were down 74% compared to releases in 1990—the year Congress passed major amendments to the Clean Air Act. The report, Benchmarking Air Emissions of the 100 Largest Electric Power Producers in […]

Many of the dangers existing at conventional power plants also threaten personnel in the wind and solar energy sectors. All workers can benefit by reviewing lessons learned and implementing corrective actions to improve health and safety performance. The expanding wind and solar energy sectors are not immune to industrial hazards affecting all energy generation markets. […]

Five of Germany’s largest lignite power plants will be mothballed to allow the country that is already phasing out nuclear power to meet ambitious climate goals by 2020.  In what it called a “milestone decision,” the government on July 2 agreed to scrap plans to impose a controversial—and by some accounts, illegal—climate tax for conventional […]

A new report from the Government Accountability Office (GAO) reveals surprising aspects about how federal subsidies for electricity have been distributed, how the power generation mix has shifted, and how consumption has transformed since 2001.  The June 29–released report, “Generation Mix has Shifted, and Growth in Consumption has Slowed, Affecting System Operations and Prices,” responds […]

Wind is no longer a niche alternative energy industry, American Wind Energy Association (AWEA) CEO Tom Kiernan told attendees at WINDPOWER 2015.  Despite policy hurdles, the wind sector has seen exponential growth and formidable cost reductions; it has the government’s endorsement for a low-carbon future; and it’s making up an ever-larger share of the nation’s […]
