Emerging solar plants scorch birds in mid-air

Quote:IVANPAH DRY LAKE, Calif. (AP) -- Workers at a state-of-the-art solar plant in the Mojave Desert have a name for birds that fly through the plant's concentrated sun rays -- "streamers," for the smoke plume that comes from birds that ignite in midair Federal wildlife investigators who visited the BrightSource Energy plant last year and watched as birds burned and fell, reporting an average of one "streamer" every two minutes, are urging California officials to halt the operator's application to build a still-bigger version. The investigators want the halt until the full extent of the deaths can be assessed. Estimates per year now range from a low of about a thousand by BrightSource to 28,000 by an expert for the Center for Biological Diversity environmental group. The deaths are "alarming. It's hard to say whether that's the location or the technology," said Garry George, renewable-energy director for the California chapter of the Audubon Society. "There needs to be some caution." The bird kills mark the latest instance in which the quest for clean energy sometimes has inadvertent environmental harm. Solar farms have been criticized for their impacts on desert tortoises, and wind farms have killed birds, including numerous raptors. "We take this issue very seriously," said Jeff Holland, a spokesman for NRG Solar of Carlsbad, California, the second of the three companies behind the plant. The third, Google, deferred comment to its partners. The $2.2 billion plant, which launched in February, is at Ivanpah Dry Lake near the California-Nevada border. The operator says it is the world's biggest plant to employ so-called power towers. More than 300,000 mirrors, each the size of a garage door, reflect solar rays onto three boiler towers each looming up to 40 stories high. The water inside is heated to produce steam, which turns turbines that generate enough electricity for 140,000 homes. Sun rays sent up by the field of mirrors are bright enough to dazzle pilots flying in and out of Las Vegas and Los Angeles. Federal wildlife officials said Ivanpah might act as a "mega-trap" for wildlife, with the bright light of the plant attracting insects, which in turn attract insect-eating birds that fly to their death in the intensely focused light rays. Federal and state biologists call the number of deaths significant, based on sightings of birds getting singed and falling, and on retrieval of carcasses with feathers charred too severely for flight.

Humans are omnivores. Like our ancestors before us. What does eating meat have to do w/ the 100% senseless loss of life via wind turbines and solar collectors have to do w/ anything ?

All buildings should be geared towards efficient heating and cooling - using ambient air and sunlight if possible. Time for a complete change in how we do our infrastructure. And I say this not because of global warming, or population growth, but just out of common sense. It's far less expensive to maintain buildings with these specifications.

Quote:Originally posted by ElvisChrist: So riddle me this, raptard: Are animals ever killed in oil spills? When an oil refinery explodes, are there ever any animals killed? When fracking fluid leeches into the groundwater, has it ever been harmful to any wildlife, anywhere, ever? If a coal mine explodes, is it remotely possible that some birds, bats, insects, or other life forms (besides humans, of course) are killed in the ensuing disaster? Help me out; I'm just trying to establish a baseline for what you think constitutes "sensible" loss of life as opposed to what you claim is "senseless loss of life". I'll bet you money you won't give me a straightforward, honest answer to the question. How many lives does it take to become "senseless"? What's the magic number, so we all know not to come back and bother you until that number is reached?

Quote:Originally posted by AURaptor: You understood my point, so the 'try English ' crap is yet just another mindless distraction. First, oil spills are not the 'norm'. Spinning blades of a turbine and extremely high heat from solar collectors are normal operating procedures for the green energy alternatives.
Quote: And just because x number of animals may die from one form of energy collection, doesn't mean other forms of energy collection get a free pass to kill even MORE critters. Sorry, it don't work that way. You're only adding to the way animals die, and that's not helping.
Quote: And since you're a troll, and refuse to discuss civilly, go frak yourself.
Quote: btw - You keep making these asinine bets that I won't answer, and then when I do answer, which is always, you never pay off.

Goodbye, kind world (George Monbiot) - In common with all those generations which have contemplated catastrophe, we appear to be incapable of understanding what confronts us.

(I hope you realize I'm paraphrasing, You DO know what that word means, right?) So, do you think you can answer the question? Hint: the answer is a number.

Quote:If you have trees shading your home, or are in an apartment building, the up to $50,000 cost of a solar system http://michaelbluejay.com/electricity/solar.html might not work for you.
Quote:Assumes you got a stream in your yard
Quote:Upfront costs are in the $25,000 range, and look like they'd require 20 years or so (compared to natural gas, which I use) to recoup the initial cost, even on geothermal heating sites.
Quote:If you're building a brand new community, this'd be a good idea. Unfortunately, a lot of residences, especially in cities, are really difficult to retrofit. [...] It is. But its very expensive to tear down all the buildings folks currently live in and build new, efficient, buildings. Its going to take a while.
