ALLETE Clean Energy has brought online the 106-megawatt Glen Ullin Energy Center in North Dakota, which will supply electricity to Xcel Energy. "North Dakota's 'all-of-the-above' energy policy strengthens local economies through projects like Glen Ullin and has made the state a national energy leader," said company President Allan Rudeck.
Researchers from the National Renewable Energy Laboratory have published a book that addresses one of three "grand challenges" for optimizing wind, with a focus on improving wind farm modeling by improving atmospheric flow calculations. "With exascale computing capabilities on the horizon, we are starting to see new possibilities for combining scales and phenomena," said NREL's Paul Veers.
The Public Service Co. of Oklahoma has arranged an agreement with the Public Utility Division of the Oklahoma Corporation Commission, the Oklahoma Attorney General's Office and other stakeholders to acquire an interest in three wind farms with a combined capacity of 675 megawatts, pending regulatory approval. The projects would use existing transmission infrastructure.
H&R Salvage has secured a conditional use permit from the Davison County Commission in South Dakota to accept and dispose of 12 turbines per day at a state landfill. The site will only accept in-state turbines and will cut them into pieces and bury them.
EDP Renewables says it will "pursue all legal courses of action in response" to Ontario's decision to withdraw approval for the 100-megawatt Nation Rise wind farm, which EDPR has nearly finished building. "Decisions of this nature should be based on science and law, yet there was no expert testimony or evidence presented at the tribunal or to the minister that would provide a reasonable rationale for the minister's decision," EDPR said.
Shipping company Norden and Kvasir Technologies, a Technical University of Denmark spinout focused on converting lignin to biofuel, have reached a partnership to develop and test plant-based biofuel as part of the Danish joint industry initiative ShippingLab. The three-and-a-half-year collaboration aims to gather knowledge on biofuel and prove that it is suitable for future shipping use.
Algae and cyanobacteria have a strong potential for synthetic biology applications --- they can survive nearly any ecosystem, can provide food and can become carbon fiber --- but knowledge and expertise about them are lacking, making their use limited, writes Kostas Vavitsas, senior research associate at the University of Athens. "The successful use of photosynthetic microbes needs different business models and unique niche areas," writes Vavitsas.
Manufacturers such as TE Connectivity and Blue Planet have found simple ways to pursue sustainability, including holding "treasure hunts" to find inefficiencies and using carbon capture technology to reduce emissions. Electronics manufacturer Morey uses data analytics to monitor product quality, leading to fewer faulty items being thrown away.
Congress should extend the wind energy Production Tax Credit and Investment Tax Credit because they're effective tools for curbing carbon emissions, plus they drive job creation and enjoy strong public support, writes Julie Tighe, president of the New York League of Conservation Voters. "It would also help achieve the emissions-reduction goals of the Paris agreement and be a significant step toward meeting [New York's] goal of 100% clean energy by 2040," she writes.
Solar-powered kiosks that pump water, smart sensors that track water usage and 3D printing are among technologies that governments and water utilities can use to increase access to clean, potable water, attendees said during a summit in Senegal this week. Countries in Africa should stop trying to fix outdated infrastructure with old solutions and should instead "take advantage of a new generation of available technology," said Senegalese President Macky Sall.
