It seems that the United States is shifting away from coal energy and moving towards sustainable, more rational energy sources.
Utilizing more clean energy into our energy mix while moving away from fossil fuels is a commonsensical energy policy, because fossil fuels are nonrenewable, exhaustible, and unsustainable; contribute to climate change; contribute to rising public health costs; pollute the environment; and are subject to volatility. As a result, an energy policy based largely on fossil fuels is imprudent and a national security nightmare. Furthermore, solar energy is the only energy source that can keep up with human consumption. More via The Huffington Post:
The report, released this week by the U.S. Energy Information Administration (EIA), had even more bad news for big polluters. Electricity generation from coal may drop another 14 percent this year. The EIA also believes coal production will decline 10 percent in 2012.
Meanwhile, wind energy is thriving. In the first quarter of 2012, the U.S. installed 1,695 megawatts of wind, one of the industry’s best quarters ever, up 53 percent from the same time last year, according to the American Wind Energy Association (AWEA). Wind projects are creating jobs and economic opportunity across the country, with 32 new projects installed in 17 states in the first quarter alone.
Gasland, a documentary that tackles the environmental side effects associated with drilling for natural gas, is up for an Oscar for the best documentary feature at the Academy Awards ceremony tomorrow. Not surprisingly, the fossil-fuel industry attacked the claims that are made in the documentary. However, given the history of environmental litigation that’s associated with fossil-fuel companies and their wrongdoings, the efforts of fossil-fuel companies to circumvent and stifle environmental regulations, and the known environmental crimes that have been committed against the human environment by the fossil-fuel industry, I believe that claims made by the fossil-fuel industry should be taken with a grain of salt. Here is a review of Gasland via Scientific American (a comprehensive review of claims made in Gasland can be found at Greenwire):
Scientific American got its hands on a pre-release copy of the film months before it aired on HBO, and the movie convinced me to write a feature article investigating the claims of fracking critics and promoters. After doing my own research and interviews, it became apparent that, like most documentaries, Gasland revealed surprising facts, amplified a few, and chose to gloss over a couple others. What writer and producer Josh Fox did achieve, regardless, was to blow the lid off the secrecy that kept most local residents, not to mention scientists and regulators, in the dark about the chemicals used in fracking and their possible effects. And he certainly put me on the reporting trail.
[Josh Fox] spends a lot of time on three Colorado households who can all set their water on fire. All three cases were investigated by Colorado’s Department of Natural Resources, and while one was indeed traced to fracking, the other two apparently have nothing to do with it. One homeowner had inadvertently drilled his well through four coal beds, which contained natural gas.
Regardless of the arguments, will Gasland take home the Oscar? It seems unlikely that arguments about its accuracy will sway the Academy much. But for the record, my money’s on Banksy.
“Gasland” is up for best documentary at Sunday’s Academy Awards ceremony. Director Josh Fox’s dark portrayal of greedy energy companies, sickened homeowners and oblivious regulators has stirred heated debate among the various stakeholders in a natural gas boom that is sweeping parts of the U.S. The film has galvanized anti-drilling activists while drawing complaints about its accuracy and objectivity.
In a letter to the academy, Lee Fuller, the executive director of an industry-sponsored group named Energy In Depth, called “Gasland” an “expression of stylized fiction” with “errors, inconsistencies and outright falsehoods.”
He asked the academy to consider “remedial actions” against the film.
Davis, the executive director, wrote to Fuller that if the academy were to act on every complaint made about a nominated film, “it would not be possible even to have a documentary category.” He said the academy must “trust the intelligence of our members” to sort out fact from fiction.
. . .
Fox said the industry’s campaign against “Gasland” has backfired.
“What they’re doing is calling more attention to the film, so I think it works against them,” the director said from Los Angeles. “But I think it shows how aggressive they are, how bullying they are, and how willing they are to lie to promote the falsehood that it’s OK to live in a gas drilling area.”
The documentary category is no stranger to controversy. Michael Moore films like “Bowling for Columbine” and “Sicko,” as well as Al Gore’s 2006 global-warming tale, “An Inconvenient Truth,” have likewise been attacked as biased and inaccurate.
When the article was published on Friday night, it was the first time an industry spokesperson deployed a shift in strategy from the industry’s standard denials and repeated assertions that fracking is safe, despite the numerous reports of problems, such as flammable water, contamination of drinking water, trucks leaking toxic and radioactive waste-water on public highways, the pollution of streams, as well as fires, and explosions in which people have been injured.
“We have to stop blaming documentaries and take a look in the mirror,” Matt Pitzarella, a spokesman for gas producer Range Resources Corp., was quoted as saying in WSJ.
However, if you go to the article, you won’t find Pitzarella’s statement because within the hour the quote disappeared, say citizen journalists, who screen captured it and posted it on Twitter. Gasland director Fox, in Los Angeles, awaiting Sunday night’s Oscar ceremony, has the screen shot of the original version. He also has questions:
“Why did this key quote disappear from the article? Why did the WSJ censor its own piece ? Does the Gas industry get to edit the Wall Street Journal?” Fox wondered. “Who pulled the quote?”
It’s more innocuous replacement from Tom Price, a Chesapeake Vice-President reads, “We need to be able to respond objectively and accurately.”
. . .
Although it’s unknown who ordered the yanking of the quote published in the Wall Street Journal, the appearance of censorship, whatever its source, does little to restore public confidence in either the industry reported on, or the media outlet doing the reporting.
Meanwhile citizens are rooting for Gasland to win the Oscar Sunday night at nationwide Gasland parties, and by writing letters to President Obama, asking for a nation-wide moratorium on fracking and safety studies. To learn more and participate, go here.
Given the large amount of water that must be used and transported during the hydrofracking process (“fracing a typical Chesapeake horizontal deep shale gas well requires an average of 4.5 million gallons per well“), the large amounts of chemicals that must be produced and used in hydrofracking, and the large amount of diesel fuel that is used in hydrofracking, I’m interested in seeing data that compares the energy input that’s required to extract natural gas during the hydrofracking process against the actual energy that’s extracted from the ground in the form of natural gas. Considering the likely high costs to the human environment and to human health, it seems to me, that if the energy return is slight or even in the negative, then why do politicians allow natural-gas drilling in such an extreme and gross negligent manner without reasonable precautions to protect the environment. Of course, the answer is money in the form of profits and subsidies. However, the price paid to land owners and the price paid for natural gas by consumers vastly undervalues and ignores the human and environmental impacts that occur during and after the drilling process.
Another problem with hydrofracking is wastewater treatment. Wastewater contains carcinogens and radioactive elements, and since “radioactivity in drilling waste cannot be fully diluted in rivers and other waterways,” it appears that wastewater from hydrofracking is a threat to drinking water supplies and to public health. Via the New York Times (emphasis added):
With hydrofracking, a well can produce over a million gallons of wastewater that is often laced with highly corrosive salts, carcinogens like benzene and radioactive elements like radium, all of which can occur naturally thousands of feet underground. Other carcinogenic materials can be added to the wastewater by the chemicals used in the hydrofracking itself.
While the existence of the toxic wastes has been reported, thousands of internal documents obtained by The New York Times from the Environmental Protection Agency, state regulators and drillers show that the dangers to the environment and health are greater than previously understood.
The documents reveal that the wastewater, which is sometimes hauled to sewage plants not designed to treat it and then discharged into rivers that supply drinking water, contains radioactivity at levels higher than previously known, and far higher than the level that federal regulators say is safe for these treatment plants to handle.
Other documents and interviews show that many E.P.A. scientists are alarmed, warning that the drilling waste is a threat to drinking water in Pennsylvania. Their concern is based partly on a 2009 study, never made public, written by an E.P.A. consultant who concluded that some sewage treatment plants were incapable of removing certain drilling waste contaminants and were probably violating the law.
The Times also found never-reported studies by the E.P.A. and a confidential study by the drilling industry that all concluded that radioactivity in drilling waste cannot be fully diluted in rivers and other waterways.
But the E.P.A. has not intervened. In fact, federal and state regulators are allowing most sewage treatment plants that accept drilling waste not to test for radioactivity. And most drinking-water intake plants downstream from those sewage treatment plants in Pennsylvania, with the blessing of regulators, have not tested for radioactivity since before 2006, even though the drilling boom began in 2008.
In other words, there is no way of guaranteeing that the drinking water taken in by all these plants is safe.
That has experts worried.
“We’re burning the furniture to heat the house,” said John H. Quigley, who left last month as secretary of Pennsylvania’s Department of Conservation and Natural Resources. “In shifting away from coal and toward natural gas, we’re trying for cleaner air, but we’re producing massive amounts of toxic wastewater with salts and naturally occurring radioactive materials, and it’s not clear we have a plan for properly handling this waste.”

There is no such thing as unlimited growth, so the U.S. government and other governments must understand the connection between energy availability and population growth by integrating sustainability into energy policy and into energy law. The current business-as-usual scenario will not meet the future energy needs of a rapidly growing world.
Also, exponential population growth and increasing energy demands will impact efforts to mitigate climate change. As a result, large amounts of renewable, clean energy will be required to sustain the energy needs of a growing world. However, not even nuclear power can keep up with escalating population growth and the future energy needs of a business-as-usual world in 2050. Solar energy, however, is the only natural energy resource that can keep up with human consumption.
Nathan Lewis provides a gloomy but sobering assessment of the challenges humanity will face in meeting its future energy needs (emphasis added):
Energy is the single most important technological challenge facing humanity today. Nothing else in science or technology comes close in comparison. If we don’t invent the next nano-widget, if we don’t cure cancer in 20 years, like it or not the world will stay the same. But with energy, we are in the middle of doing the biggest experiment that humans will have ever done, and we get to do that experiment exactly once. And there is no tomorrow, because in 20 years that experiment will be cast in stone. If we don’t get this right, we can say as students of physics and chemistry that we know that the world will, on a timescale comparable to modern human history, never be the same.
The currency of the world is not the dollar, it’s the joule.
. . .
Humanity’s current energy consumption rate is 13 trillion thermal watts, or 13 terawatts.
. . .
The United States consumes a quarter of the world’s energy, at a rate of about 3.3 terawatts[.]
. . .
With population and GDP growth conspiring together, we would then obtain a tripling of energy demand by 2050. This is partly mitigated, however, by the fact that we’re using energy more efficiently per unit of GDP. The ratio of energy consumption to GDP has been declining at about 1 percent, globally averaged, per year. The United States actually saves energy at a faster rate, about 2 percent per year. Because we have such a high per-capita energy baseline consumption, it is easier for us to save off that base, whereas the developing countries save less. The “business as usual” scenario assumes that this will continue, and if we project that down, we will achieve an average energy consumption of two kilowatts per person within our lifetimes. (The United States now uses 10 kilowatts per person.) But factor in population growth and conservative economic growth, and we’ll still need twice as much energy as we need now.
In terms of average thermal load, a person on a 2,000-calorie-per-day diet is basically a hundred-watt lightbulb. And in our highly mechanized western agricultural system, the energy embedded in food—to run the farm and grow the food and transport it to the supermarket and put it in the refrigerator—is 10 to 20 times the energy content of the food itself. And the farther you live from the food source, the more embedded energy you consume. If we are 100-watt lightbulbs, this means that just keeping us fed requires one to two kilowatts.
. . .
Ice cores taken near Vostok Station, Antarctica, show that the CO2 level has been in a narrow band between 200 and 300 parts per million by volume (ppmv) for the last 425,000 years; data from other cores have extended this back to 670,000 years. Current CO2 levels are about 380 ppmv. “Business as usual” will require 10 trillion watts, 10 terawatts, of carbon-free power, and it never stabilizes CO2 levels—they just keep going up. So even on that track, we are betting against data that goes back for almost a million straight years, and hoping that this time, we get lucky.
. . .
[U]nfortunately, there is no natural destruction mechanism for carbon dioxide in our atmosphere. Unlike ozone depletion, it will not heal by itself through chemical processes. In our highly oxidizing atmosphere, CO2 is an end product. The lifetimes of CO2 in the atmosphere are well known, and the time for 500 to 600 ppmv of CO2 to decay back to 300 ppmv is between 500 and 5,000 years. Which means that the CO2 we produce over the next 40 years, and its associated effects, will last for a timescale comparable to modern human history. This is why, within the next 20 years, we either solve this problem or the world will never be the same. How different that world will be, we won’t know until we get there.
If we want to hold CO2 even to 550 ppmv, even with aggressive energy efficiency we will need as much clean, carbon-free energy within the next 40 years, online, as the entire oil, natural gas, coal, and nuclear industries today combined—10 to 15 terawatts. This is not changing a few lightbulbs in Fresno, this is building an industry comparable to 50 Exxon Mobils. Furthermore, if we wait 30 years, the amount of carbon-free energy we’ll need will be even greater, and needed even faster, because in the meantime we will have put out 30 years of accumulated CO2 emissions that will not go away for centuries to millennia. So stabilizing at 550 ppmv will then require about 15 to 20 terawatts of carbon-free power in 2050.
. . .
So let’s look at carbon-neutral energy sources. We could go nuclear, which is the only proven technology that we have that could scale to these numbers. We have about 400 nuclear power plants in the world today. To get the 10 terawatts we need to stay on the “business-as-usual” curve, we’d need 10,000 of our current one-gigawatt reactors, and that means we’d have to build one every other day somewhere in the world for the next 50 straight years. I’ve been giving this talk in one version or another for five years—we should have already built on the order of 1,000 new reactors, or double what’s ever been built, just to stay on track. So we’re really behind.
There isn’t enough terrestrial uranium on the planet to build them as once-through reactors. We could get enough uranium from seawater, if we processed the equivalent of 3,000 Niagara Falls 24/7 to do the extraction. Which means that the only credible nuclear-energy source today involves plutonium. That’s never talked about by the politicians, but it’s a fact. Forgive my facetiousness, but on some level we should be thanking North Korea and Iran for doing their part to mitigate global warming. We’d need about 10,000 fast-breeder reactors and, by the way, their commissioned lifetime is only 50 years. That means that after we choose this route, we’re building one of them every other day, or more rapidly, forever.
We don’t have time for the physicists to figure out how to make nuclear fusion reactors—they’ve been saying it will be demonstrated (although not economical) in 35 years, and they’ve been saying that for the last 50. If we assume they’re right this time, then ITER, a multinational demonstration fusion reactor being built in the south of France, will demonstrate break even—that is, it will put out as much energy as it takes to run it—in 35 years, and it will run for all of one week before the entire machine will, by design, disintegrate in the presence of that high-neutron radiation and temperature flux. And in the meantime we would have to build a commercial fission reactor every day for the next 30 years. It’s not going to happen.
. . .
One hundred twenty thousand terawatts of solar power hits the earth . . . It is the only natural energy resource that can keep up with human consumption. Everything else will run up against the stops, soon. In fact, more solar energy hits the earth in one hour than all the energy the world consumes in a year.
Between 2005 and 2009, oil and gas service companies injected more than 30 million gallons of diesel fuel or hydraulic fracturing fluids containing diesel fuel in wells in 19 states, according to an investigation released by House Energy and Commerce Committee Democrats.
The fossil-fuel industry doesn’t make or produce coal, natural gas, petroleum, or any other type of fossil fuel. The industry merely extracts materials that have been made by natural processes within the Earth.
However, the fossil-fuel industry reaps huge profits by polluting the human environment and natural landscapes. Although, the fossil-fuel industry has a well-documented history of making profits at the expense of the environment and human health, the industry has received billions in subsidies from governments and taxpayers. The entire process is deplorable and immoral. More via the Dallas Morning News (emphasis added):
Drilling companies violated federal law by injecting 16 million gallons of diesel fuel underground in Texas to extract natural gas, senior House Democrats said Monday.
In a letter to the Environmental Protection Agency , the lawmakers said the companies failed to obtain necessary permits when they used diesel fuel in their hydraulic fracturing mixtures. The fracturing process, which is widely used in North Texas’ Barnett Shale, has come under scrutiny as environmental groups and some residents allege it has contaminated drinking water supplies.
The congressional inquiry, which began in early 2010 when Democrats controlled the House, did not conclude that the use of diesel polluted any drinking-water sources. The Democrats said the firms they questioned couldn’t provide data on the proximity of drilling operations to underground sources of drinking water.
. . .
Nationwide, over 32 million gallons of diesel fuel or fluids containing diesel were injected underground, the lawmakers wrote. The drilling firms used 10.2 million gallons of “straight diesel fuel” and 21.8 million gallons of products containing at least 30 percent diesel, the letter states
The ugly truth of the natural gas boom via the post-gazette.com:
The natural gas boom gripping parts of the United States has a nasty byproduct: wastewater so salty, and so polluted with metals like barium and strontium, that most states require drillers to get rid of the stuff by injecting it down shafts thousands of feet deep.
But not in Pennsylvania, one of the states at the center of the gas rush. In Pennsylvania, the liquid that gushes from gas wells is only partially treated for substances that could be environmentally harmful, then dumped into rivers and streams from which communities get their drinking water.
In the two years since the frenzy of activity began in the vast underground rock formation known as the Marcellus Shale, Pennsylvania has been the only state letting its waterways serve as the primary disposal place for huge amounts of wastewater produced by a drilling technique called hydraulic fracturing, or fracking. State regulators, initially caught flat-footed, tightened the rules this year for any new water treatment plants, but let existing operations continue discharging water into rivers.
At least 3.6 million barrels of the waste were sent to treatment plants that empty into rivers during the 12 months ending June 30, state records show. That’s enough to cover a square mile with more than 8 1/2 inches of brine.
Halliburton is among twelve companies that were cited in the House probe. Via Reuters:
The probe of diesel use in hydraulic fracturing, a practice that has allowed drillers to tap abundant shale gas, found that oil services firms such as Halliburton (HAL.N: Quote) and BJ Services, which was bought by Baker Hughes Inc (BHI.N: Quote), injected millions of gallons of fluids containing the fuel into wells between 2005 and 2009. A total of 12 companies were cited in the probe for using diesel without proper permits.
Critics say the chemicals used in the process, called “fracking,” can contaminate drinking water.
In 2003, the Environmental Protection Agency entered into a voluntary agreement with Halliburton, BJ Services and Schlumberger (SLB.N: Quote) to eliminate the use of diesel fuel in hydraulic fracturing fluids injected into coalbed methane wells.
In addition, a 2005 energy law exempted hydraulic fracturing, or fracking, from regulation under the Safe Drinking Water Act, except when diesel is used.
Still, the probe found that no oil and gas service companies sought or were issued permits for the use of diesel fuel in fracking between 2005 and 2009.
Democrats who sponsored the probe in the House of Representatives urged the EPA to look into this matter.
Competing interests and litigation kept the Cape Wind Project from being permitted and constructed for almost a decade. Now, fishers are concerned with a proposal by Deepwater Wind to construct a large offshore wind farm in federal waters between Rhode Island and Massachusetts.
“We understand the value of this thing,” said Chris Brown, president of the Rhode Island Commercial Fishermen’s Association. “But we don’t want to become collateral damage.”
Brown said that Deepwater had reached out to fishing groups and tried to work with them in determining a location for the 1,000-megawatt wind farm, but they couldn’t find a site that wouldn’t affect the fishing industry.
“It’s all critical habitat,” he said. “There’s someone making a living on every square inch.”
Deepwater said it purposely designed the wind farm to accommodate commercial and recreational boaters. The project, called the Deepwater Wind Energy Center, is divided into two main arrays, one of about 50 turbines and another of 150 turbines. The company would space the machines 0.7 miles apart to allow fishing boats to more easily travel through the groupings. Corridors 1.5 miles long would also cut through parts of the project for boat navigation.
But Brown and Lanny Dellinger, president of the Rhode Island Lobstermen’s Association, said it may not be Deepwater’s decision whether boats would be allowed to travel into the wind farm. Dellinger said he knows of insurers in Europe who won’t allow it for fear of a vessel hitting a turbine.
“Commercial fishing and wind farms are not compatible,” he said.
State officials, however, said that the two industries can indeed coexist.
“Our goal here is not only to achieve a renewable-energy future for Rhode Island,” said Keith Stokes, executive director of the state Economic Development Corporation. “We’re not going to supplant the fishing and boating industries in Rhode Island. We know how important they are to the state.”
It seems that the United States is shifting away from coal energy and moving towards sustainable, more rational energy sources.
