Emissions may cause global north-to-south shift in wind power

In the next century, wind resources may decrease in many regions of the Northern Hemisphere and could sharply increase in some hotspot regions down south, according to a study by University of Colorado Boulder researchers. The first-of-its-kind study predicting how global wind power may shift with climate change appears in Nature Geoscience. “There’s been a lot

Younicos upgrades battery storage at Duke Energy’s Notrees wind farm in Texas

Younicos has completed the installation and commissioning of an upgraded 36-MW, battery-based energy storage system at the site of Duke Energy’s 153-MW Notrees Windpower Project in West Texas. The company replaced previously deployed lead-acid technology with advanced Samsung SDI lithium-ion batteries. The Notrees system has been in operation since 2012, actively participating in Texas grid

EIA releases December’s U.S. short-term energy forecast

The U.S. Energy Information Administration (IEA) has released its short-term energy outlook (STEO) for December, and into early 2018. It expects natural gas and coal shares of utility-scale electricity generation  to remain relatively unchanged through 2018. Both natural gas and coal are forecast to hover near 32% and 31%, respectively, in 2018. The IEA anticipates

Vaisala and WindSim complete largest-ever validation of remote sensing in complex terrain

Vaisala, a global provider in environmental and industrial measurement, has collaborated with WindSim, a pioneer in computational fluid dynamics (CFD) modeling, on a study that demonstrates how the effects of complex terrain on wind measurements collected by remote sensing units can be mitigated. The collaboration has included the most extensive complex terrain validation of remote sensing

Energy Department announces $18.5 million for offshore wind research

Today, U.S. Secretary of Energy Rick Perry announced $18.5 million in new Department of Energy (DOE) funding for an offshore wind research and development (R&D) consortium that will conduct U.S.-specific research aimed at reducing the cost of offshore wind in the U.S. This consortium will be a cooperative private-public innovation hub addressing topics, including wind plant technology

Energy-related carbon-dioxide emissions decreased in most states from 2005 to 2015

The United States has a diverse energy landscape that is reflected in differences in state-level emissions profiles. Between 2005 and 2015, energy-related carbon dioxide (CO2) emissions decreased in 43 states (including the District of Columbia) and increased in 8 states. On a per-capita basis, energy-related CO2 emissions decreased in 49 states (including the District of

Fraunhofer researches how to prevent rain erosion on turbine blades

Smalls drops, big impact: Even just minor rain erosion damage on rotor blade surfaces can impair performance and shorten the service life of wind turbines. This is according to research and development institute, Fraunhofer Iwes, which has launched a three-year study into the effect of rain erosion on wind-turbine blades. Fraunhofer has been operating a

Stem to build the first energy storage virtual power plants in Japan

Stem Inc., the global provider of artificial intelligence-driven energy storage services, and Mitsui & Co., Ltd. are partnering to build  one of the first aggregated fleets of industrial customer-sited energy storage operating in Japan. This pilot will help inform Japan’s plans to develop aggregated demand response resources as flexible capacity to manage the variability from

Vestas wins 40 MW U.S. order for 80% PTC qualifying wind-turbine components

  Vestas has received an order for 40 MW of turbine components that qualify for 80% of the PTC value, under the bipartisan PATH act that Congress passed in 2015. The long-term phasedown terms set in the PATH act have resulted in nearly $50 billion of investment in the U.S., including the expansion of factories,

Iowa reduces GHG emissions, thanks to renewables

The Iowa Department of Natural Resources’ (DNR) mandated “2016 Iowa Greenhouse Gas Inventory Report” shows greenhouse gas emissions (GHG) in Iowa have decreased for the second year in a row. This is primarily from a decrease in power plant emissions, but also an increase in renewables. Statewide emissions decreased 2% from 2015 levels and 9% from
