It’s not just Wind Turbines that kill wildlife, from the Wall Street Journal:
“A giant solar-power project officially opening this week in the California desert is the first of its kind, and may be among the last, in part because of growing evidence that the technology it uses is killing birds.”
“The $2.2 billion solar farm, which spans over five square miles of federal land southwest of Las Vegas, includes three towers as tall as 40-story buildings. Nearly 350,000 mirrors, each the size of a garage door, reflect sunlight onto boilers atop the towers, creating steam that drives power generators.”
“The owners of the project— NRG Energy Inc., NRG, Google Inc. GOOG and BrightSource Energy Inc., the company that developed the “tower power” solar technology—call the plant a major feat of engineering that can light up about 140,000 homes a year.”
“Ivanpah is among the biggest in a spate of power-plant-sized solar projects that have begun operating in the past two years, spurred in part by a hefty investment tax credit that expires at the end of 2016. Most of them are in California, where state law requires utilities to use renewable sources for a third of the electricity they sell by 2020.”
“Utility-scale solar plants have come under fire for their costs–Ivanpah costs about four times as much as a conventional natural gas-fired plant but will produce far less electricity—and also for the amount of land they require.
That makes for expensive power. Experts have estimated that electricity from giant solar projects will cost at least twice as much as electricity from conventional sources. But neither the utilities that have contracted to buy the power nor state regulators have disclosed what the price will be, only that it will be passed on to electricity customers.”
“The BrightSource system appears to be scorching birds that fly through the intense heat surrounding the towers, which can reach 1,000 degrees Fahrenheit.
The company, which is based in Oakland, Calif., reported finding dozens of dead birds at the Ivanpah plant over the past several months, while workers were testing the plant before it started operating in December. Some of the dead birds appeared to have singed or burned feathers, according to federal biologists and documents filed with the state Energy Commission.”
“Regulators said they anticipated that some birds would be killed once the Ivanpah plant started operating, but that they didn’t expect so many to die during the plant’s construction and testing. The dead birds included a peregrine falcon, a grebe, two hawks, four nighthawks and a variety of warblers and sparrows. State and federal regulators are overseeing a two-year study of the facility’s effects on birds.”
“The agency also is investigating the deaths of birds, possibly from colliding with structures, found at two other, unrelated solar farms. One of those projects relies on solar panels and the other one uses mirrored troughs. Biologists think some birds may have mistaken the vast shimmering solar arrays at all three installations for a lake and become trapped on the ground after landing.”
