Wingate, Texas [New York Times] If he could have ever seen the FPL Group’s new wind farm here, Don Quixote would have certainly fallen off his horse. With jagged rows, scores of miles long, of 421 wind turbines scraping the big West Texas sky with blades as long as 132 feet, it is by far the biggest in the world. […]
Gigantic wind turbines could soon be scraping the skies…
For several years, Grant County Public Utility District (PUD) struggled with high temperatures – and subsequent failures – of the thrust bearings of two units at its 907-MW Priest Rapids hydro project.
Today’s topics include why Indian villagers would take hammers to a large-scale solar array; what happens when developers cut corners in order to install solar at the lowest price possible and what are the unintended consequences of the Trade Expansion Act of 1962 which is currently being considered as a reason to impose tariffs on steel and aluminum imported into the United States.
The latest round of solar auctions in Mexico yielded an unheard-of average price of US $20.57 per MW, including a $17.70 per MW bid by Enel, a coup for the government. However, as developers and EPCs scramble to under-bid one another in the current market, the price eventually will erode the quality that is deliverable. Indeed, this auction round may have hit the crossing point suggests Enrique Roig, the director of the Solar Steel business of Gonvarri Steel Services, based in Madrid.
Accurately aligning vertical shafts in hydro turbine-generator units requires precise measurements, skilled personnel, and the ability to make sound engineering judgments.
Back in 1979, President Jimmy Carter put a large solar thermal system on the White House, calling on American businesses and consumers to make solar the future, not a "curiosity" or an "example of a road not taken." Unfortunately, six years later, the panels were ripped down and government support was scaled back. The market collapsed and the solar thermal industry has been scraping by ever since.
The Global Wind Energy Council released its annual market statistics last week in Brussels. The 2017 market remained above 50 GW, with Europe, India and the offshore sector having record years. Chinese installations were down slightly—‘only’ 19.5 GW—but the rest of the world made up for most of that. Total installations in 2017 were 52,573 MW, bringing the global total to 539,581 MW.
PV and ME question #8: Do we really need so many trade fairs for solar? Imagine you are flying, comfy in a windowseat, looking down on the Earth. Magical. Dreamlike. Mind-blowing. Poetic. And so environmentally unfriendly. To watch jet trails from the ground painting crisscrossed geometric patterns in the sky is to watch an art form that is heaven-sent. But […]
Scientists at the Energy Department's National Renewable Energy Laboratory (NREL) have developed an enzyme that could change the economics of biofuel conversion by converting biomass to sugars up to 14 times faster and much cheaper than competing catalysts in enzyme cocktails today.
