There are however many useful places yet to be explored. I can only imagine how much power could be generated from correctly-designed turbines in the Columbia Gorge, or along the Straits of Juan de Fuca.

Yes, 7 BILLION TONS!
That's like ~2,000lbs of coal being burned every year for every human on the planet...
And it blows my mind that humans can even create a reason to oppose something, anything, that can help to reduce this.
What harm can you possibly make a rational argument for to be greater than burning 7 BILLION TONS of coal every damn year.
To put that in perspective, if Mount Rainer that I know we both fondly look upon when it's not covered by clouds were entirely made of coal, from my estimations, the entire mountain would be burned and put into the air in 5.2 years...
Yes, if the mountain were entirely made of coal (I used a density of 2100kg per M^3 for my estimation), it would be all burned and put into the air in 5.2 years. That's the scale we mine, transport, and burn coal.





The most notable opponent of Cape Wind was the late Sen. Ted Kennedy, a champion of green energy who, to the dismay of environmentalists, fought against the wind farm. The Kennedy compound will have a view of the wind turbines.


You are unusually intelligent and well informed (on some topics). If someone isn't as well informed as you are it doesn't mean they are dumb. Also not every site is suitable for large wind turbines.liveforphysics wrote:I can't tell if you're being serious or not, and my apologies if you are. This has to be one of the dumbest posts on ES.
liveforphysics wrote:So, when you DON'T put a 1MW wind turbine up, but you do use the same amount of energy you used before, does anyone want to know how much coal it requires to produce that same 1MW of energy?
~645lbs of coal per hour...
That's 5.6 MILLION pounds of coal per year to generate 1MW of power. Now, how many animals and damage do you think is caused by mining, transporting by trains and trucks, processing and burning 5.6MILLION pounds of coal over the course of a year?

Talk about Canaries in a Coal Mine. We are killing entire forests (it's worse in Europe)!Take a drive along the backroads of western North Carolina, especially through Ashe, Watauga, and Avery Counties, and you will find the birthplace of all those Christmas trees that show up in roadside stands the week before Thanksgiving. To many people, the neat rows of carefully pruned Fraser fir, Abies fraseri, trees create a picturesque scene, but for raw, natural scenic beauty, you need to climb a little higher in the mountains and visit the true origin of all those trees. The natural Fraser fir forests that blanket our highest peaks are cool, dark, hauntingly beautiful places.
Or, at least, they used to be.
Only a few decades ago, the Fraser fir natural community—generally found above 6,000 feet in elevation—was a seemingly healthy ecosystem, with a tight canopy of fir trees, an understory of American ash and a few shrubs, and a thick ground cover of moss, ferns, and herbs. Today, that ecosystem no longer exists. In its place is a jungle of skeletons, with dead gray boles lying scattered about like so many pick-up sticks. Many of the dead trees still stand as sentinels to something gone wrong. The resultant opened canopy has completely altered the ecosystem, allowing plants that don't belong here to become established. Where you once needed snowshoes to walk over the luxuriant moss without sinking in, today you need leather chaps to wade through the thick blackberries and other weeds....
...In the mid 1980s, Dr. Robert Bruck of N.C. State University studied the forests on Mount Mitchell, and although he suspected that air pollution was a contributing factor to the forest decline, he had no hard evidence. But one day in 1987 "serendipity struck" as Bruck recalls. "We were up on the mountain on a beautiful June day taking pictures of bud break. That night, a heavy cloud came in and sat on top of the mountain. It stayed there for the next 15 hours, through the next day...We sampled continuously and found the cloud had an average pH of 2.71. That's 940 times more acidic than clear rain water-almost the acidity of vinegar. The next afternoon, the sun came out again, and these young needles all over the mountain started to turn brown."
Dr. Bruck collected bushel baskets of the needles and took them to the EPA lab in Raleigh, where tests showed the brown areas had 17 times more sulfur than the healthy areas. The sulfur was in the form of sulfate, for which there are only two airborne sources: volcanic eruption and the combustion of fossil fuels. "And there weren't any volcanoes erupting", Bruck recollects....
But for those of us who have or had Mercury fillings (aka "silver" fillings - 55% Mercury) environmental exposure is the least of our worries in terms of our own health.Fish and shellfish contain relatively high levels of mercury and arsenic. It is recommended that you omit fish and shellfish from your diet for one week prior to collecting the urine specimen.
