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 […]

The New York State Public Service Commission (PSC) approved New York’s Clean Energy Standard on August 1, likely saving three upstate nuclear power plants, while requiring 50% of the state’s electricity to come from renewable energy sources by 2030. Gov. Andrew Cuomo (D) praised the action in a statement following the announcement. “New York has […]

Dutch power grid operator TenneT on June 10 unveiled plans for a large-scale island transmission hub in the North Sea that could connect numerous offshore wind farms and transmit their generated power to the Netherlands, the UK, Belgium, Norway, Germany, and Denmark via direct current (DC) cables. Those cables, or “spokes” could also serve as […]

Poland, a country where hard coal and lignite power plants currently generate about 85% of the power, has passed a law that stymies a wind power expansion and is now mulling draft legislation that will help boost investments in new coal capacity. The eastern European country has bucked the trend toward renewable power that many […]

After years of planning and sluggish development, 2016 may be the year that offshore wind power development takes off in China. Once it does, the market will be large. Offshore wind power has a very important role to play in easing power shortages in coastal areas of China and in responding to climate change effectively. […]

Lawmakers in Germany have voted to replace subsidies for wind and solar with competitively priced electricity prices. The country’s upper (Bundesrat) and lower (Bundestag) legislative chambers on July 8 voted to adopt an amendment to the Renewable Energy Sources Act (EEG 2016) introduced by Minister of Economics and Energy Sigmar Gabriel. The legislation aims to […]

Siemens on July 5 entered the competition for the largest wind turbine in the world with an upgrade of its SWT-7.0-154 model. The new SWT-8.0-154 turbine boosts power output over the earlier model through upgraded magnet technology. Other components remain largely the same over the earlier model and the smaller SWT-6.0-154 turbine, Siemens said. The […]

Renewable generation is usually characterized as more environmentally friendly than fossil fuels, and in many respects, that’s true. But there is a growing recognition that solar and wind generation have their own impacts, and an increasing number of manufacturers and generators are looking for ways to minimize them. Iceland might be about the last place […]

Courtesy: Ad Meskens/Wikimedia Commons Europe has been in the forefront of renewable energy development, and though the scientific research on wildlife impacts is limited, European environmentalists and developers are beginning to create baseline frameworks and guidelines. Developers around the world can learn from their experience. As more renewable energy systems come online, providers hope to […]

Plans are under way to install a pilot 1-MWh lithium battery–based storage system in 2018 at the world’s first floating wind farm in Aberdeenshire, Scotland. The “Batwind” system, to be installed at

High penetration of grid-connected utility solar increases market demand for accurate regional solar forecasting tools to manage energy scheduling and trading    VAISALA CORPORATION                         PRESS RELEASE                                  APRIL 28, 2016   Recent analysis from Vaisala, a global leader in environmental and industrial measurement, reveals that in 2015 energy from grid-connected, utility-scale solar plants surpassed wind for […]

The U.S. Senate passed an amendment on April 26 that would restore funding for wind energy research and development (R&D) in fiscal year 2017 to $96.4 million—the same amount funded this fiscal year. The amendment passed by a vote of 54–42 as part of Senate consideration of the Energy and Water Development and Related Agencies […]

China has edged past the European Union (EU) in terms of total installed wind capacity, with 145.1 GW to the EU’s 141.6 GW. This means that China, which erected a stunning 30.5 GW in 2015—nearly half of

Vattenfall has dismantled five offshore wind turbines—with a total capacity of 10 MW—at the Yttre Stengrund wind farm in Kalmar Sound, Sweden. The month-long decommissioning project was the first in the

New reports released this week see big growth in renewables from the recently extended federal tax credits, but big uncertainty due to the possible end of the Clean Power Plan (CPP). New York-based consulting firm Rhodium Group says investment plans in the power sector will be radically different if the Clean Power Plan doesn’t happen. […]

In its recently released Energy Technology Perspectives 2015, the International Energy Agency (IEA) noted that innovation in the energy sector differs from progress in other sectors in that it tends to move

Nearly five years after the world’s first large-scale floating deepwater wind turbine was erected 11 kilometers (km) offshore Karmøy, southeast Norway, Norwegian energy firm Statoil has made a final

In a major boost to the wind and solar industries, Congressional leaders agreed on a multiyear extension of renewable energy tax credits, which could provide several years of predictable policies, encouraging investment in new projects. The tax credits are part of a 2,009-page omnibus-spending bill unveiled by the House Appropriations Committee on Dec. 15. The […]

In the UK this August, two massive offshore wind developments were thrown into tumult. A consortium that secured the UK government’s approval in early August to build an array of offshore wind farms in the Dogger Bank development off the east coast of Yorkshire said it would proceed with only four projects instead of the […]

Replacing blades on a wind turbine is not a simple task. Blades range from 40 to 60 meters in length and can weigh 16 tons or more. Combined with hub heights that can exceed 100 meters and locations that are, by definition, subject to prevailing winds, replacing blades becomes challenging. Add in the cost of […]

A new policy approved by India’s cabinet will simplify its foray into offshore wind power, says a key stakeholder.  The National Offshore Wind Energy Policy approved by the Prime Minister Narendra Modi’s Union Cabinet on Sept. 9 designates the Ministry of New & Renewable Energy (MNRE) as the nodal ministry for use of offshore areas […]
