54.5 mpg will fuel a national renewal

By ROLAND HWANG  | 8/22/12 4:30 AM EDT  As reported in Politico

With the darkest days of the recession behind us, Americans are looking to  better economic times. They also are looking forward to their politicians  working together to find solutions.

While there are many areas where different sides are far apart, there is a  very good news story expected from Washington this week. It’s an issue that  almost all Americans can get behind: higher fuel efficiency.

An agreement set to be finalized by the Obama Administration as  soon as this week promises that by 2025, new vehicles will get an average of  54.5 miles per gallon. This builds on standards already in place, which by 2016  will raise the average fuel efficiency of the new passenger vehicle fleet to  35.5 mpg.

The standards will be introduced incrementally. For consumers, this means  that in less than 15 years, everything from compact cars to pickup trucks will,  on average, burn about half as much gas as vehicles driven today. This saves  about $8,000 in costs over the life of a new vehicle.

This is Washington at its best, working to move America forward.

Republicans and Democrats, automakers and environmental groups supported the  stronger standard because it redirects hard-earned cash away from the gas pump  and back into your wallet. They also understood that the standard fortifies  national security and protects the environment.

And this agreement puts Americans back to work.

Thousands of new jobs are being created in the automotive industry, the  largest manufacturing employer in the U.S. According to the Bureau of Labor  Statistics, the auto industry has added more than 230,000 jobs since June 2009,  when the industry scraped bottom. Most of these jobs are in the manufacturing  sector, but U.S. auto dealerships are beefing up their payrolls as well.

Stronger standards give automakers a long-term roadmap to improve vehicle  efficiency.

By greening the Rust Belt, the U.S. can seize global leadership in  innovative, fuel-efficient technologies – a market historically dominated by  Europe and Asia.

The jobs that accompany this domestic expansion aren’t outsourced; they  remain at home.

In Saginaw, Mich., for example, a century-old auto supplier called Nexteer  Automotive recently added 650 employees to help manufacture electric power  steering components for pickup trucks. These components replace more  energy-intensive hydraulic systems. Electric power steering is a fast-growing  segment of Nexteer’s business, and automakers who want to squeeze more  efficiency from their fleet are driving the increased demand.

Outside the auto industry, job growth will expand even further – by more than  half a million jobs, many in discretionary sectors like services and retail – because money saved at the pump will be spent on things like tuition, new  clothes, or a vacation.

The benefits don’t stop there. Cutting energy use while driving also reduces  our dependence on oil. By 2030, the 54.5 mpg standard will slash oil imports by  one-third. This enhances national security and strengthens the economy by  investing money in the Midwest – not in the volatile Middle East.

Fuel efficiency standards also protect the environment by reducing carbon  pollution equal to taking 85 million cars off the road. This helps fight climate  change that leads to costly droughts and dangerous heat waves. Less pollution  also means a healthier populace and lower medical bills.

Washington responded to America’s demand for more fuel efficient cars. By  implementing a smart, tough standard, Washington showed that it is committed to  creating good jobs and continuing our economic recovery.

54.5 mpg is a standard that works for America.

Oil Prices Spike Exacerbated By Wall Street Speculation, Federal Reserve Study Finds

As reported by Zach Carter for Huffington Post

WASHINGTON — Two economists at the St. Louis Federal Reserve have published findings that indicate that Wall Street speculation is responsible for 15 percent of the increase in oil prices over the past decade, a finding with significant implications for the recent sharp rise in gas prices.

While politicians have little ability to alter the price swings of commodities like oil, regulators have both the authority and policy tools to do so. The Commodity Futures Trading Commission is responsible for overseeing the financial market for oil. The 2010 Wall Street reform bill gave the CFTC new power to limit excessive speculation, but the rule will not go into effect until later this year.

According to St. Louis Fed economists Luciana Juvenal and Ivan Petrella, speculation in oil markets was the second-biggest factor behind the past decade’s price run-up, behind increased global demand for oil, which accounted for 40 percent of the increase.

“Speculation was the second-largest contributor to oil prices and accounted for about 15 percent of the rise,” the economists wrote. “The effect that speculation had on oil prices over this period coincides closely with the dramatic rise in commodity index trading — resulting in concerns voiced by policymakers.”

Commodity indexes allow speculators to bet on the price of several commodities at once, and have become very popular investment tools for both Wall Street investment companies and pension funds. Between 2004 and 2008, the total volume of trading activity in commodity indexes jumped from $13 billion to about $260 billion, according to research by Michael Masters, founder of Masters Capital Markets and the financial reform nonprofit Better Markets.

Masters and others have noted that speculation can exaggerate price swings otherwise dictated by fundamental supply-and-demand dynamics, and can also force prices to move contrary to supply-and-demand predictions. During 2008, when oil prices soared to their highest level on record, they did so during a period in which global demand was low and global supply was high — what should have been a recipe for lower prices.

The most recent Fed study concludes that economic fundamentals are still the primary determinant, saying only that speculation can “exacerbate” price swings.

“Global demand remained the primary driver of oil prices from 2000 to 2009,” Juvenal and Petrella wrote. “That said, one cannot completely dismiss a role for speculation in the run-up of oil prices of the past decade. Speculative demand can and did exacerbate the boom-bust cycle in commodity prices. Ultimately, however, fundamentals continue to account for the long-run trend in oil prices.”

Fuel prices are currently at the highest level on record for the month of March, a phenomenon upon which presidential candidates are seizing to attack President Barack Obama on the issue at campaign stops. The financial reform bill Obama signed into law in 2010 allowed the CFTC to write its new rule, designed to curb price movements influenced by excessive speculation. The rule limits the size of the bets that individual traders can make on any given commodity.

Solar makes sense

As reported in Philadelphia Inquire May 30, 2011

With Pennsylvania
boasting the nation’s second largest number of solar-industry jobs, state
officials would be foolish to let the sun set on such a nascent but promising
industry. But that could happen due to a temporary mismatch between solar-energy
financing and market demand.

The construction of more than 4,000 solar projects has been a roaring
success, responsible for generating several thousand jobs at 600 solar
businesses. Growing that industry from scratch, with state and federal aid, also
boosted the use of nonpolluting and renewable energy. That will be particularly
helpful in meeting summer’s peak demand.

Yet, the boom in solar projects has outpaced the amount of solar energy
utilities are required to buy under the state’s alternative-energy rules. That
has depressed the value of solar-energy credits needed to provide a return on
photovoltaic solar systems, which have a steep, up-front price tag.

The best way for state officials to spur solar to new heights would be to
boost the modest solar-energy standard – now far lower than neighboring states,
at only 0.5 percent – by 2021. But last year, that idea ran into strong
opposition from Exelon and other utilities, coal producers, and business groups
– and a certain Republican candidate for governor.

Fortunately, a fellow Republican, State Rep. Chris Ross from Chester County,
unveiled a legislative proposal Tuesday that should be more to Gov. Corbett’s
liking. Ross would accelerate the amount of solar energy utilities are required
to purchase for the next few years, but leave the overall standard at just 0.5
percent. He would also follow other states by barring out-of-state solar
producers contributing to the solar glut in Pennsylvania.

The Ross proposal amounts to a tweak, but one that could be critical to
maintaining the state’s foothold in solar energy. Corbett and Republican
legislative leaders could fall back on tea-party ideological antagonism toward
so-called government mandates – or they could prove themselves progressive
enough to embrace a modest plan that makes sense for the state’s 21st-century
economy.

What Obama Should Say About the Deficit

Economic View

 

By CHRISTINA D. ROMER

 

Published: January 15, 2011

BY the time President Obama gave his State of the Union address last year, the speech felt like an old friend. It had been part of my life — from the brainstorming sessions in late November 2009 to the last minute fact-checking. I knew when all of my favorite lines were coming. That led to an awkward moment during the address when I sprang to my feet, applauding the president’s tacit endorsement of the free-trade agreement with South Korea, before noticing that the only other person cheering seemed to be Ron Kirk, the special trade representative.

This year, instead of being on the floor of Congress with the rest of the cabinet, I will be watching on television with the rest of the country. Instead of knowing what is coming, I can write about what I hope the president will say. My hope is that the centerpiece of the speech will be a comprehensive plan for dealing with the long-run budget deficit.

I am not talking about two paragraphs lamenting the problem and vowing to fix it. I am looking for pages and pages of concrete proposals that the administration is ready to fight for. The recommendations of the bipartisan National Commission on Fiscal Responsibility and Reform that the president created are a very good place to start.

The need for such a bold plan is urgent — both politically and economically. Voters made it clear last November that they were fed up with red ink. President Obama should embrace the reality that his re-election may depend on facing up to the budget problem.

The economic need is also pressing. The extreme deficits of the last few years are largely a consequence of the terrible state of the economy and the actions needed to stem the downturn. But even with a strong recovery, under current policy the deficit is projected to be more than 6 percent of gross domestic product in 2020. By 2035, if the twin tsunami of rising health care costs and the retirement of the baby boomers hits with full force, we will be looking at deficits of at least 15 percent of G.D.P.

Such deficits are not sustainable. At some point — likely well before 2035 — investors would revolt and the United States would be unable to borrow. We would become the Argentina of the 21st century.

So what should the president say and do? First, he should make clear that the issue is spending and taxes over the coming decades, not spending in 2011. Republicans in Congress have pledged to cut nonmilitary, non-entitlement spending in 2011 by $100 billion (less if recent reports are correct). Such a step would do nothing to address the fundamental drivers of the budget problem, and would weaken the economy when we are only beginning to recover.

Instead, the president should outline major cuts in spending that would go into effect over the next few decades, and that he wants to sign into law in 2011.

Respected analysts across the ideological spectrum agree that rising health care spending is the biggest source of the frightening long-run deficit projections. That is why the president made cost control central to health reform legislation. He should vow not just to veto a repeal of the legislation, but to fight to strengthen its cost-containment mechanisms.

One important provision of the law was the creation of the Independent Payment Advisory Board, which must propose reforms if Medicare spending exceeds the target rate of growth. But the legislation exempted some providers and much government health spending from the board’s purview. The president should work to give the board a broader mandate for cost control.

The fiscal commission recommended that military spending — which has risen by more than 50 percent in real terms since 2001 — grow much more slowly in the future. It also proposed thoughtful ways to slow the growth of Social Security spending while protecting the disabled and the poor. And it recommended caps on nonmilitary, non-entitlement spending.

President Obama needs to explain that while these cuts will be painful, there is no way to solve our budget problem without shared sacrifice. At the same time, he should give a ringing endorsement of government investment in infrastructure, research and education, which increases productivity and thus improves both our standard of living and the budget situation over time. And, following the fiscal commission, he should ensure that spending cuts not fall on the disadvantaged.

Finally, the president has to be frank about the need for more tax revenue. Even with bold spending cuts, there will still be a large deficit. The only realistic way to close the gap is by raising revenue. Some of it can and should come from higher taxes on the rich. But because there are far more middle-class families than wealthy ones, much of the additional money will have to come from ordinary people. Since any agreement will have to be bipartisan, Congressional Republicans will have to come to terms with this fact as well.

AGAIN, the fiscal commission has made sensible proposals. It recommended broad tax reform that lowers marginal tax rates and cuts tax expenditures — deductions and exemptions for mortgage interest, employer-provided benefits, charitable giving, and so on. Such tax reform cannot be revenue-neutral — it needs to increase tax receipts. But it can make the system simpler, fairer and more efficient while doing so.

Limiting the exemption of employer-provided health benefits would have the further advantage of making companies and workers more cost-conscious about health care.

Another revenue measure should be a tax on polluting energy. Basic economics says that something that has widespread adverse effects should be taxed. A gradual increase in the gasoline tax would raise revenue and encourage the development of cleaner energy sources. A broader carbon tax would be even better.

None of these changes should be immediate. With unemployment at 9.4 percent and the economy constrained by lack of demand, it would be heartless and counterproductive to move to fiscal austerity in 2011. Indeed, the additional fiscal stimulus passed in the lame-duck session — particularly the payroll tax cut and the unemployment insurance extension — is the right policy for now. But legislation that gradually and persistently trims the deficit would not harm the economy today. Indeed, it could increase demand by raising confidence and certainty.

The president has a monumental task. It’s extremely hard to build consensus around a deficit reduction plan that will be painful and unpopular with powerful interest groups. The only way to do so is to marshal the good sense and patriotism of the American people. That process should start with the State of the Union.

What is shale gas and why is it important?

As reported by

Shale gas refers to natural gas that is trapped within shale formations. Shales are fine-grained sedimentary rocks that can be rich sources of petroleum and natural gas. Over the past decade, the combination of horizontal drilling and hydraulic fracturing has allowed access to large volumes of shale gas that were previously uneconomical to produce. The production of natural gas from shale formations has rejuvenated the natural gas industry in the United States.

Did You Know?

Sedimentary rocks are rocks formed by the accumulation of sediments at the Earth’s surface and within bodies of water. Common sedimentary rocks include sandstone, limestone, and shale.

U.S. Natural Gas Supply, 1990-2035

Did You Know?

Shale gas in 2009 made up 14% of total U.S. natural gas supply. Production of shale gas is expected to continue to increase, and constitute 45% of U.S. total natural gas supply in 2035, as projected in the EIA Annual Energy Outlook 2011.

Does the U.S. Have Abundant Shale Gas Resources?

Of the natural gas consumed in the United States in 2009, 87% was produced domestically; thus, the supply of natural gas is not as dependent on foreign producers as is the supply of crude oil, and the delivery system is less subject to interruption. The availability of large quantities of shale gas will further allow the United States to consume a predominantly domestic supply of gas.

According to the EIA Annual Energy Outlook 2011, the United States possesses 2,552 trillion cubic feet (Tcf) of potential natural gas resources. Natural gas from shale resources, considered uneconomical just a few years ago, accounts for 827 Tcf of this resource estimate, more than double the estimate published last year. At the 2009 rate of U.S. consumption (about 22.8 Tcf per year), 2,552 Tcf of natural gas is enough to supply approximately 110 years of use. Shale gas resource and production estimates increased significantly between the 2010 and 2011 Outlook reports and are likely to increase further in the future.

Where is Shale Gas Found?

Shale gas is found in shale “plays,” which are shale formations containing significant accumulations of natural gas and which share similar geologic and geographic properties. A decade of production has come from the Barnett Shale play in Texas. Experience and information gained from developing the Barnett Shale have improved the efficiency of shale gas development around the country. Another important play is the Marcellus Shale in the eastern United States. Surveyors and geologists identify suitable well locations in areas with potential for economical gas production by using both surface-level observation techniques and computer-generated maps of the subsurface.

How is Shale Gas Produced?

Two major drilling techniques are used to produce shale gas. Horizontal drilling is used to provide greater access to the gas trapped deep in the producing formation. First, a vertical well is drilled to the targeted rock formation. At the desired depth, the drill bit is turned to bore a well that stretches through the reservoir horizontally, exposing the well to more of the producing shale.

Hydraulic fracturing (commonly called “fracking” or “hydrofracking”) is a technique in which water, chemicals, and sand are pumped into the well to unlock the hydrocarbons trapped in shale formations by opening cracks (fractures) in the rock and allowing natural gas to flow from the shale into the well. When used in conjunction with horizontal drilling, hydraulic fracturing enables gas producers to extract shale gas at reasonable cost. Without these techniques, natural gas does not flow to the well rapidly, and commercial quantities cannot be produced from shale.

How is Shale Gas Production Different from Conventional Gas Production?

Conventional gas reservoirs are created when natural gas migrates toward the Earth’s surface from an organic-rich source formation into highly permeable reservoir rock, where it is trapped by an overlying layer of impermeable rock. In contrast, shale gas resources form within the organic-rich shale source rock. The low permeability of the shale greatly inhibits the gas from migrating to more permeable reservoir rocks. Without horizontal drilling and hydraulic fracturing, shale gas production would not be economically feasible because the natural gas would not flow from the formation at high enough rates to justify the cost of drilling.

What Are the Environmental Issues Associated with Shale Gas?

Natural gas is cleaner-burning than coal or oil. The combustion of natural gas emits significantly lower levels of key pollutants, including carbon dioxide (CO₂), nitrogen oxides, and sulfur dioxide, than does the combustion of coal or oil. When used in efficient combined-cycle power plants, natural gas combustion can emit less than half as much CO₂ as coal combustion, per unit of energy released.

However, there are some potential environmental issues that are also associated with the production of shale gas. Shale gas drilling has significant water supply issues. The drilling and fracturing of wells requires large amounts of water. In some areas of the country, significant use of water for shale gas production may affect the availability of water for other uses, and can affect aquatic habitats.

Drilling and fracturing also produce large amounts of wastewater, which may contain dissolved chemicals and other contaminants that require treatment before disposal or reuse. Because of the quantities of water used, and the complexities inherent in treating some of the chemicals used, wastewater treatment and disposal is an important and challenging issue. If mismanaged, the hydraulic fracturing fluid can be released by spills, leaks, or various other exposure pathways. The use of potentially hazardous chemicals in the fracturing fluid means that any release of this fluid can result in the contamination of surrounding areas, including sources of drinking water, and can negatively impact natural habitats.

Solar-Powered Plane Flies for 26 Hours

Solar Impulse, piloted by André Borschberg, flew for 26 hours and reached a height of 28,543 feet, setting a record for the longest and highest flight ever made by a solar plane.

By ALAN COWELL

Published: July 8, 2010

PARIS — Slender as a stick insect, a solar-powered experimental airplane with a huge wingspan completed its first test flight of more than 24 hours on Thursday, powered overnight by energy collected from the sun during a day aloft over Switzerland.

The organizers said the flight was the longest and highest by a piloted solar-powered craft, reaching an altitude of just over 28,000 feet above sea level at an average speed of 23 knots, or about 26 miles per hour.

The plane, Solar Impulse, landed where it had taken off 26 hours and 9 minutes earlier, at Payerne, 30 miles southwest of the capital, Bern, after gliding and looping over the Jura Mountains, its 12,000 solar panels absorbing energy to keep its batteries charged when the sun went down.

The pilot, André Borschberg, 57, a former Swiss Air Force fighter pilot, flew the plane from a cramped, single-seat cockpit, buffeted by low-level turbulence after takeoff and chilled by low temperatures overnight.

“I’ve been a pilot for 40 years now, but this flight has been the most incredible one of my flying career,” Mr. Borschberg said as he landed, according to a statement from the organizers of the project. “Just sitting there and watching the battery charge level rise and rise, thanks to the sun.” He added that he had flown the entire trip without using any fuel or causing pollution. The project’s co-founder, Dr. Bertrand Piccard, who achieved fame by completing the first nonstop, round-the-world flight by hot air balloon in 1999, embraced the pilot after he landed the plane to the cheers of hundreds of supporters.

“When you took off, it was another era,” The Associated Press quoted Dr. Piccard as saying. “You land in a new era where people understand that with renewable energy you can do impossible things.”

The project’s designers had set out to prove that — theoretically at least — the plane, with its airliner-size, 208-foot wingspan, could stay aloft indefinitely, recharging batteries during the day and using the stored power overnight. “We are on the verge of the perpetual flight,” Dr. Piccard said.

The project’s founders say their ambition is for one of their craft to fly around the world using solar power. The propeller-driven Solar Impulse, made of carbon fiber, is powered by four small electric motors and weighs around 3,500 pounds. During its 26-hour flight, the plane reached a maximum speed of 68 knots, or 78 miles per hour, the organizers said.

The seven-year-old project is not intended to replace jet transportation — or its comforts.

Just 17 hours after takeoff, a blog on the project’s Web site reported, “André says he’s feeling great up there.”

It continued: “His only complaints involve little things like a slightly sore back as well as a 10-hour period during which it was minus 20 degrees Celsius in the cockpit.”

That made his drinking water system freeze, the post said and, worst of all, caused his iPod batteries to die.

Bill Gates: We need global ‘energy miracles’

By John D. Sutter, CNN //

Long Beach, California (CNN) — Microsoft Corp. founder and philanthropist Bill Gates on Friday called on the world’s tech community to find a way to turn spent nuclear fuel into cheap, clean energy.

“What we’re going to have to do at a global scale is create a new system,” Gates said in a speech at the TED Conference in Long Beach, California. “So we need energy miracles.”

Gates called climate change the world’s most vexing problem, and added that finding a cheap and clean energy source is more important than creating new vaccines and improving farming techniques, causes into which he has invested billion of dollars.

The Bill & Melinda Gates Foundation last month pledged $10 billion to help deploy and develop vaccines for children in the developing world.

The world must eliminate all of its carbon emissions and cut energy costs in half in order to prevent a climate catastrophe, which will hit the world’s poor hardest, he said.

“We have to drive full speed and get a miracle in a pretty tight timeline,” he said.

Gates said the deadline for the world to cut all of its carbon emissions is 2050. He suggested that researchers spend the next 20 years inventing and perfecting clean-energy technologies, and then the next 20 years implementing them.

The world’s energy portfolio should not include coal or natural gas, he said, and must include carbon capture and storage technology as well as nuclear, wind and both solar photovoltaics and solar thermal power.

“We’re going to have to work on each of these five [areas] and we can’t give up on any of them because they look daunting,” he said. “They all have significant challenges.”

Gates spent a significant portion of his speech highlighting nuclear technology that would turn spent uranium — the 99 percent of uranium rods that aren’t burned in current nuclear power plants — into electricity.

That technology could power the world indefinitely; spent uranium supplies in the U.S. alone could power the country for 100 years, he said.

A “traveling wave reactor” would burn uranium waste slowly, meaning a 60-year supply could be added to a reactor at once and then not touched for decades, he said.

Gates also called for innovation in battery technology.

“All the batteries we make now could store less than 10 minutes of all the energy [in the world],” he said. “So, in fact, we need a big breakthrough here. Something that’s going to be of a factor of 100 better than what we have now.”

Gates called for more investment in climate-related technology. He said he is backing a company called TerraPower, which is working on an alternate form of nuclear technology that uses spent fuel.

Money that goes into research and development will pay bigger returns than other investments, he said, especially if money goes into energy sources that will be cheap enough for the developing world to afford.

Clean energy technologies must be installed in poorer countries as they develop, he said.

“You’d be stunned at the ridiculously low costs of innovation,” said Gates, who received a standing ovation for his remarks.

If he could wish for anything in the world, Gates said he would not pick the next 50 years’ worth of presidents or wish for a miracle vaccine.

He would choose energy that is half as expensive as coal and doesn’t warm the planet.

The sudden emergence of the shale-gas frenzy

By Andrew Maykuth

Inquirer Staff Writer

Posted on Sun, Jan. 31, 2010

In their exuberance, oil- and gas-industry officials repeat a single refrain when describing the natural gas from Pennsylvania’s Marcellus Shale:

A game-changer.

Tony Hayward, chief executive officer of oil giant BP P.L.C., was the latest to gush enthusiastically when he called unconventional natural gas resources like the Marcellus “a complete game-changer.”

“It probably transforms the U.S. energy outlook for the next 100 years,” Hayward said Thursday at the World Economic Forum in Davos, Switzerland.

The breathtaking emergence of natural gas as America’s energy savior was not in the cards. Just four years ago, after Hurricanes Katrina and Rita devastated Gulf Coast rigs and rattled gas markets, energy pundits forecast a bleak winter of short supplies, high prices, and low thermostats.

The vast scale of shale-gas resources has come into focus quickly, and industry officials are touting the possibility of steady supplies for decades to come.

The Potential Gas Committee in Colorado last year revised its outlook of America’s future gas supply – up 35 percent in just two years. The forecast was the highest in its 44-year history.

The Marcellus Shale is the nation’s fastest-growing producing area. Though it lies under five states, about 60 percent of its reserves are in Pennsylvania, according to Terry Engelder, a Pennsylvania State University geologist.

“In terms of its impact on Pennsylvania, this is probably without peer in the last century,” said Engelder, whose projections in 2008 alerted the public about the size of the Marcellus.

“America’s energy portfolio has undergone a first-order paradigm shift just in the last two years,” he said. “This is such an exciting thing.”

Not everyone has climbed aboard the bandwagon. Some environmentalists are uneasy about the hydraulic-fracturing process that has unlocked the shale gas. The technique requires the injection of millions of gallons of water into a well to break up the shale to initiate production.

And some analysts say they believe the gas industry’s estimates are too optimistic.

“I would look at all this with a bit of healthy skepticism,” said Arthur E. Berman, a Houston gas-industry consultant, who says he believes some operators have overstated the production potential and understated the cost of Texas shale-gas wells. His pointed criticism got him banished from one trade journal – and invited to speak at scores of investor workshops.

“Two years ago, we were talking about importing gas from the Middle East,” he said. “And now we have a hundred-year supply of domestic gas?”

Berman said he had been unable to conduct a similar analysis of Marcellus wells because Pennsylvania law allows operators to keep their production data secret for five years, unlike other states, where output is reported to taxing authorities promptly.

“If something looks too good to be true,” he said, “I need to look more closely.”

Questioning voices such as Berman’s are uncommon in the industry, which portrays natural gas as abundant, cheap, and cleaner than coal and oil – a domestically produced “bridge fuel” to ease the transition to renewable wind and solar generation.

For companies like UGI Corp. – the Valley Forge energy company that operates regulated utilities in Pennsylvania that sell natural gas to retail customers and operates unregulated subsidiaries that consume and transport natural gas – the Marcellus Shale represents a game-changing opportunity on several fronts.

“That activity in the Marcellus Shale is really a win-win, not only for our regulated business, but also our nonregulated business,” UGI chief executive Lon R. Greenberg told analysts in a conference call last week.

Officials at UGI and other Pennsylvania gas utilities say retail customers will benefit in the long run, as utilities begin buying their supplies from Marcellus sources, saving pipeline costs from the Gulf Coast.

UGI’s utilities are in a strong position because many of their 578,000 customers are in Marcellus cities such as Scranton, Wilkes-Barre, and Williamsport. The utility could eventually work out deals to buy gas directly from producers.

Though UGI has no interest in becoming a gas producer, the company is exploring the possibilities for investing in “midstream” pipelines that tie the Marcellus wells to the interstate pipelines that move gas to lucrative urban markets like New York. Expansion of the pipeline infrastructure is critical to opening the Marcellus to exploration.

In addition, UGI is looking at expanding its underground gas-storage operations in Western Pennsylvania, said Brad Hall, president of UGI Energy Services.

“There is a bit of a gold-rush mentality,” he said, “but in this case, there’s really gold.”

UGI may also reap some other, unintended benefits.

The company’s power-generation subsidiary last year announced a $125 million project to convert its aging Hunlock Power Station near Wilkes-Barre from coal to natural gas.

Hall said the decision was made before the Marcellus abundance was fully understood. But when the plant comes online in 2011, it is likely to find eager sellers of fuel nearby.

“It makes us look like we were really smart.”

King Coal

Written by Robert F. Kennedy Jr

Over the past decade, nearly one hundred coal burning power plants have died in the proposal stage trumped by the legitimate objections of local communities fearful of a dirty deadly fuel that is neither cheap nor clean. Ozone and particulates from coal plants kill tens of thousands of Americans each year and cause widespread illnesses and disease. Acid rain emissions have destroyed the forests over the length of the Appalachian and sterilized one in five Adirondack lakes. Neurotoxic mercury raining from these plants has contaminated fish in every state–including every waterway in nineteen states–and poisons over a million American women and children annually. Coal industry strip mines have already destroyed 500 mountains in Appalachia, buried 2,000 miles of rivers and streams and will soon have flattened an area the size of Delaware. Finally, coal, which supplies 46% of our electric power, is the most important source of America’s greenhouse gases.

Beating our deadly and expensive coal addiction will be lucrative. America’s cornucopia of renewable energy resources and the recent maturation of solar, geothermal and wind technologies will allow us to meet most of our future energy needs with clean, cheap, abundant renewables. Bright Source, a solar thermal provider, has just signed contracts to provide California with 2.6 gigawatts of power annually from desert mirror farms. Construction costs are about the same per gigawatt as a coal plant and half the cost of a nuke plant. Once built, the energy is free forever. In contrast, once you build a coal plant, your biggest costs–fuel extraction and transportation and the harm from emissions–are just the beginning.

In the short term, a revolution in natural gas production over the past two years, has left America awash in natural gas and has made it possible to eliminate most of our dependence on deadly, destructive coal practically overnight–and without the expense of building new power plants.

How? Well it’s pretty easy. Around 900 of America’s coal plants–78% of the total–are small (generating less than half a gigawatt), antiquated, and horrendously inefficient. Their average age is 45 years, with many limping past 75. These ancient plants burn 20% more coal per megawatt hour than modern large coal units and are 60-75% less fuel efficient than high-efficiency gas plants. These small units account for less than 42% of the actual capacity for coal fired power but almost one half the total emission of the entire energy sector! The costs of operation, maintenance, capital improvements and repair costs of these antiquated worm-eaten facilities, if properly assessed, would make them far more expensive to run than natural gas plants. However, energy sector pricing structures make it possible for many plant operators to pass those costs to the public and make choices based on fuel costs, which in the case of coal, appears deceptively cheap because of massive subsidies.

Mothballing or throttling back these plants would mean huge cost savings to the public and eliminate the need for more than 350 million tons of coal, including all 30 million tons harvested through mountain top removal. Their closure would reduce U.S. mercury emissions by 20-25%, dramatically cut deadly particulate matter and the pollutants that cause acid rain, and slash America’s CO2 from power plants by 20%–an amount greater than the entire reduction mandated in the first years of the pending Climate Change Legislation–at a fraction of the cost.

These decrepit generators can be eliminated very quickly–in many instances literally overnight by substituting power from America’s existing and underutilized natural gas generation, which is abundant, cleaner and more affordable and accessible today than dirty coal.

Since 2007, the discovery of vast supplies of deep shale gas in the United States, along with advanced extraction methods, have created stable supply and predictably low prices for most of the next century. Of the 1,000 gigawatts of generating capacity currently required to meet national energy demand, 336 are coal fired, many of which are utilized far more heavily than for cleaner gas generation units. Surprisingly, America actually has more gas generation capacity–450 gigawatts–than coal. But most of the costs for coal-fired units are ignored in deciding when to operate these units. Public regulators traditionally require utilities to dispatch coal first. For that reason, high efficiency gas generators, which can replace a large percentage of U.S. coal, are used only 36% of the time. By simply changing the dispatch rule nationally, we could quickly reduce power generated by existing coal-fired plants and achieve massive emissions reductions. The new rule would change the order in which gas and coal fired plants are utilized by requiring that whenever coal and gas plants are competing head-to-head, the gas generation must be dispatched first.

To quickly gain further economic and environmental advantages, the larger, newer coal plants that remain in operation should be required to co-fire with natural gas. Many of these plants are already connected to gas pipelines and can easily be adapted to burn gas as 15 to 20% of their fuel. Experience shows using gas to partially fuel these plants dramatically reduces forced outages and maintenance costs and can be the most cost effective way to reduce CO2 emissions. This change can immediately achieve an additional 10 to 20% reduction in coal use and immediately reduce dangerous coal emissions.

Natural gas comes with its own set of environmental caveats. It is a carbon-based fuel and is extraction from shale, the most significant new source, if not managed carefully, can cause serious water, land use, and wildlife impacts, especially in the hands of irresponsible producers and lax regulators. But those impacts are dwarfed by the disastrous holocaust of coal and can be mitigated by careful regulation.

The giant advantage of a quick conversion from coal to gas is the quickest route for jumpstarting our economy and saving our planet.
