New research shows Natural Gas far more dangerous for climate stability —Seth Gunning

Received yesterday on U.S. CO2 emissions lowest in 20 years: that's good and bad: natural gas is methane, after all. -jsq

Yet another comprehensive article. I might also add that one of the major down-falls (if not the most significant) of large-scale conversions to natural gas is the resources lifecycle methane emissions.

As your readers likely know, Methane is about twenty times as 'potent' a greenhouse gas as Carbon Dioxide. That is to say, it is far more efficient at trapping heat then Co2. So, less methane has a far greater impact on climate disruption then more Co2.

Natural Gas, from the point of combustion, releases about half the amount of Co2 released from burning coal, and about 30% of what's released in burning oil. To keep the benefits of reduced Co2 levels when switching from coal to natural gas, natural gas wells and transport lines must leak less then 2% of methane into the atmosphere. Recent research from Cornell is showing that Fracking wells are regularly releasing more then 4%, and often as much as 8% —far exceeding the 2% threshold— and thus making Natural Gas a far more dangerous resource for climate stability.

U.S. CO2 emissions lowest in 20 years: that’s good and bad

The good news: because utilities such as Southern Company are switching away from coal U.S. emissions of CO2 are the lowest they’ve been in 20 years. The bad news: they’re switching to natural gas, which not only still emits carbon dioxide, it pollutes groundwater through fracking, requires a lot of groundwater to do the fracking in the first place, and then uses more groundwater for cooling. But the further good news is cheaper energy sources drive out expensive ones, and wind and solar are already cheaper than nuclear and coal, and solar is already cheaper than natural gas. Oh, and solar and wind emit no CO2.

“There’s a very clear lesson here. What it shows is that if you make a cleaner energy source cheaper, you will displace dirtier sources,” said Roger Pielke Jr., a climate expert at the University of Colorado.

While conservation efforts, the lagging economy and greater use of renewable energy are factors in the CO2 decline, the drop-off is due mainly to low-priced natural gas, the agency said.

A frenzy of shale gas drilling in the Northeast’s Marcellus Shale and in Texas, Arkansas and Louisiana has caused the wholesale price of natural gas to plummet from $7 or $8 per unit to about $3 over the past four years, making it cheaper to burn than coal for a given amount of energy produced. As a result, utilities are relying more than ever on gas-fired generating plants.

Both government and industry experts said the biggest surprise is how quickly the electric industry turned away from coal. In 2005, coal was used to produce about half of all the electricity generated in the U.S. The Energy Information Agency said that fell to 34 percent in March, the lowest level since it began keeping records nearly 40 years ago.

And that’s why Southern Company (SO) turned towards natural gas: it’s cheaper! SO still prefers nuclear and coal before gas, as SO CEO Thomas A. Fanning keeps reminding us. But even SO couldn’t ignore “the revolution in shale gas”, which is cheaper prices through fracking. Solar PV costs dropped 50% last year alone. How long can SO ignore that?

“Natural gas is not a long-term solution to the CO2 problem,” Pielke warned….

Vogtle circular firing squad delaying opening

Southern Company and the other owners of Plant Vogtle are blaming the contractors (who are suing them) for further delays in construction. How much money will they waste before they never open?

Kristi E. Swartz wrote for the AJC yesterday, Disputed costs at Vogtle rise,

Georgia Power and a group of municipal and cooperative electric companies are building twin 1,100-megawatt reactors, the first in the United States to win permits in 30 years. The total expected cost of the project is $14 billion, but potential cost overruns at Vogtle, located in Waynesboro in east Georgia, continue to grow, according to the recent Southern Co. regulatory filing.

Delays in getting federal licensing approvals for the new reactor design and then for the entire project have been cited as the chief culprit.

Because of the dispute with contractors over the additional costs, “the owners are evaluating whether maintaining the currently scheduled commercial operation dates of 2016 and 2017 remains in the best interest of their customers,” the filing said. The total amount of the cost overruns could be well over $900 million; Georgia Power owns 45.7 percent of the project, so its share is $425 million, the latest filing said. Originally the overrun was projected at $400 million when the issue was first made public in April.

Up another $25 million since April? How long until it gets into billions of cost overruns? Which will be paid by whom?

More concerned about feeding cars than the hungry? —Michael G. Noll

Received Tuesday on Georgia EPD to suspend consideration of some new farm water permit applications 07/30/2012. -jsq

And Southern Company/Georgia Power are still pushing for power plants that waste hundreds of thousands of gallons of water daily (nuclear, biomass)? Water for cooling purposes instead of agriculture? That's about as insane as corn for the production of ethanol instead of feeding people. And how much water do wind mills or solar panels need once they have been installed? About as much as they create problems with air pollution and radioactive waste: zero!

Please note a recent article by George Monbiot on a global crisis caused by investments made in biofuels (e.g. ethanol from corn). To quote from the article (13 August 2012, Hunger Games):

"Already, 40% of US corn (maize) production is used to feed cars(6). The proportion will rise this year as a result of the smaller harvest. Though the market for biodiesel is largely confined to the European Union, it has already captured seven per cent of the world's output of vegetable oil(7). The European Commission admits that its target (10% of transport fuels by 2020) will raise world cereal prices by between 3 and 6%(8). Oxfam estimates that with every 1% increase in the price of food, another 16 million people go hungry."

Where does this leave our "Christian" values as we are obviously more concerned about feeding cars than the hungry?

Vermont protests against wind vs. nuclear

Compare 6 arrested of about 25 demonstrators against Green Mountain Power’s wind energy project on Lowell Mountain vs. 130 arrested of a thousand protesting in March against the Vermont Yankee nuclear plant.

Also notice what they were protesting. The location on Lowell Mountain, as damaging the mountain top and being unsightly, plus:

“I feel like they [GMP] only went through the public process to a point, and the process is flawed,” said Young, a self-employed logger and farmer from Westfield. “Community members don’t have the resources to have a strong voice. It’s complex, expensive, and lawyers don’t want to do it.”

At Vermont Yankee, the protests were against radioactive leaks, nuclear waste, and this:

Yankee’s initial 40-year license expired Wednesday. The plant is still running, under a 20-year extension from the federal Nuclear Regulatory Commission—despite a vote by the state senate not to allow the plant to continue operating in Vermont.

A common theme is lack of democratic oversight, although even that seems greater in degree for Vermont Yankee. We are familiar with that issue in Georgia, where there’s an election going on for Public Service Commissioners and legislators.

Another common theme is that it’s complex and expensive, which is indeed an issue for big wind projects. Power companies like them as big as they can build them because that fits their corporate bureaucracy. They can instead be smaller and distributed. Nuclear power plants, on the other hand, are always big, bureaucratic, and expensive.

While I thoroughly sympathize with the Lowell Mountain protesters about the mountain top issues, I don’t see anything about them protesting the risk of a wind spill. Risks of nuclear radioactive contamination are very real, and are among the Vermont Yankee protesters’ main issues. Wind off the coast of Georgia would not have that problem.

The reality of the solar industry —Michael Noll

Received Friday on Plant Vogtle water use. -jsq

Please note a recent article in the New York Times about the best alternative to nuclear power in Georgia: The Secret to Solar Power By Jeff Himmelman, 9 August 2012.

To quote from the article:

“… the reality of the [solar] industry — as evidenced by the enormous investments that companies like Google and Bank of America are making in residential solar power — is that it has rapidly become a smart, practical and profitable investment.”

When will Southern Company & Georgia Power finally wake up? —Michael G. Noll

Received today on Plant Vogtle water use. -jsq

Energy projects such as biomass plants, coal firing plants, and nuclear power plants waste enormous amounts of water. The once proposed 40MW biomass plant in Valdosta would have consumed 800,000 gallons of water DAILY. Considering that for years now we are experiencing record drought conditions and heat waves in the US, this should make everyone’s hair stand up on the back of their necks. (For more information see “Electricity’s Thirst on a Precious Resource”.)

Add to this scenario a recent decision by the US Nuclear Regulatory Continue reading →

Plant Vogtle water use

Apparently the nuclear reactors at Plant Vogtle will use more water than the City of Savannah, and more than agricultural uses for the middle Savannah River watershed. Much of the water (3/4?) is evaporated, leaving less for drinking, farming, and everything else. What goes back in the river is rest warmer than it came out, affecting everything that lives in the river. Remind me: why are we building those nukes instead of solar and wind generators, which use no water while producing power?

Plant Vogtle currently uses 43.2 million gallons of water a day, and with all 4 units, is planned to use 86.4 million gallons of water a day, or 2% of the *average* flow of the Savannah River, according to UNC’s Powering A Nation journalism team, 9 June 2010.

That’s more than the City of Savannah, according to the City of Savannah.

Incumbents won Snapping Shoals EMC board election

Insurgents lost an EMC board election, but made their point anyway. Following up on the three locals running for the board of Snapping Shoals EMC, they lost, but remember Snapping Shoals EMC quit coal-pushing Power4Georgians when they announced they were running.

Crystal Tatum wrote for the Henry Daily Herald 26 July 2012, Morris, Snapping Shoals EMC incumbents win by landslide,

CONYERS — Members of the Snapping Shoals Electric Membership Corporation (EMC) have returned to office three incumbents in a rare contested election to the agency’s 11-member board of directors.

EMC board members set policies and oversee the finances and administration of Snapping Shoals. They serve staggered, three-year terms. The non-profit EMC is a consumer-owned cooperative in Covington, providing service to about 95,000 consumers in an eight-county area, including Henry County.

Gene Morris of Henry County, Walter Johnson of DeKalb County, and Anthony Norton of Rockdale, were being challenged because of their support to build the coal-fire power Plant Washington. Kaye Shipley, also of Henry County, Albert Roesel of Newton County, and Cheryl Mathis of DeKalb County form the group challenging the three. Voting took place at the cooperative’s annual meeting Thursday in Georgia International Horse Park in Conyers.

In the District 2 Rockdale post, 2,400 ballots were cast, with Norton beating Roesel 2,157 to 224. Nineteen ballots were voided. In the District 3 DeKalb County Post, Johnson garnered 2,099 votes to Cheryl Moore-Mathis’ 280. Twenty-one votes were voided. In the District 4 Henry County race, 2,392 ballots were cast, with Morris getting 2,082 votes to Shipley’s 300. Ten were voided. Newton County District 1 representative Pete Knox ran unopposed.

Amusingly, incumbent Gene Morris termed it a David and Goliath struggle with the incumbents as David. I’m not sure most people think of the power company as the little guy….

The story mentioned a post-election press release by the challengers, but didn’t link to it. No problem; Continue reading →
