Help the military stop climate change through sustainable renewable energy

In memory of Armistice Day, the eleventh hour of the eleventh day of the eleventh month, when World War I ended, let’s help the military get us off of oil and to deal with climate change so fewer people will die in wars.

John M. Broder wrote for NYTimes 9 November 2012, Climate Change Report Outlines Perils for U.S. Military,

Climate change is accelerating, and it will place unparalleled strains on American military and intelligence agencies in coming years by causing ever more disruptive events around the globe, the nation’s top scientific research group said in a report issued Friday.

The group, the National Research Council, says in a study commissioned by the C.I.A. and other intelligence agencies that clusters of apparently unrelated events exacerbated by a warming climate will create more frequent but unpredictable crises in water supplies, food markets, energy supply chains and public health systems.

Hurricane Sandy provided a foretaste of what can be expected more often in the near future, the report’s lead author, John D. Steinbruner, said in an interview.

“This is the sort of thing we were talking about,” said Mr. Steinbruner, a longtime authority on national security. “You can debate the specific contribution of global warming to that storm. But we’re saying climate extremes are going to be more frequent, and this was an example of what they could mean. We’re also saying it could get a whole lot worse than that.”

…

Climate-driven crises could lead to internal instability or international conflict and might force the United States to provide humanitarian assistance or, in some cases, military force to protect vital energy, economic or other interests, the study said.

This is in addition to the even more obvious connection between war and U.S. dependence on foreign oil which the veterans in Operation Free want to fix by helping us shift to clean renewable energy.

“In Iraq… the lines would stretch up to ten miles long under the hot sun, under constant risk of attack by extremists. I realized then just how vulnerable it makes any country to be dependent on oil, especially the United States, which uses nearly a quarter of the world’s supply.”

We also heard last year from Col. Dan Nolan (U.S. Army ret.) that the Marines in Afghanistan realized Continue reading →

A billion people on solar: India

Figure 6: Solar Sheep (Concentrix Solar PV concentrator plant) Two professors in India have done the math and found that there’s plenty of available land in India (much of it on rooftops) to power its billion people on solar energy alone. And solar uses less water than nuclear or coal, also as we already knew for the U.S.

Today in The Hindu, India can meet energy needs sans N-power: Study,

According to their study, 4.1 per cent of the total uncultivable and Figure 3: 1GWh Land area per energy source waste land area in India is enough to meet the projected annual demand of 3,400 terawatt-hour (TWh) by 2070 by solar energy alone (1 terawatt-hour per year equals 114 megawatts). The land area required will be further reduced to 3.1 per cent “if we bring the other potential renewable energy sources of India into picture”, they claim. They conclude that land availability is not a limiting constraint for the solar source as believed.

Southern Company: let’s do the renewable energy study for Georgia

Mark Z. Jacobson's study shows offshore wind is plentiful from Virginia to Maine Let's do the study for Georgia! Southern Company brags about its private R&D:

Research & Development (since the 1960s)

  • Awarded more than $1.3 billion to conduct more than $3.8 billion of research and development.
  • Qualified for $412 million of investment tax credits for a 21st century coal plant being built in Mississippi.

OK, SO, let's see you do the study to show what we can really do with conservation, efficiency, wind, sun, and less natural gas than we have now. Sure, in the Georgia Bight we do have to contend with hurricanes. But a "great, big company" like SO should be able to focus its vaunted private R&D on that problem and solve it.

Maybe SO doesn't want to do that because the result might show there is no need for any coal plants, nor new natural gas plants, nor any nuclear plants, which would mean Georgia Power would have to give up its nuclear-funding rate-hike stealth tax and SO would have to give up its $8.3 billion loan guarantee. Hey, we might even need to change the 1973 Georgia Electric Territorial Act, and that might damage Georgia Power's guaranteed profit! Nevermind that Georgia Power and SO might make more profit if they got out in front on solar and wind power and a smart grid.

If SO won't do it, how about we elect some Public Service Commissioners and legislators who will? For jobs, energy independence, and profit, oh, and clean air and plenty of water!

All U.S. east coast electricity could come from offshore wind 3 seasons out of 4

Why build nukes when wind can provide 3/4 of our power? While Southern Company claims to be “a company that is engaged in offering solutions, not just rhetoric”, yet does nothing about wind off the Georgia coast, researchers in far California have demonstrated we can get 3/4 of all needed east coast electricity from offshore wind.

Bjorn Carey wrote for Stanford Report 14 September 2012, Offshore wind energy could power entire U.S. East Coast, Stanford scientists say

A new analysis by Stanford researchers reveals that there is enough offshore wind along the U.S. East Coast to meet the electricity demands of at least one-third of the country.

The scientists paid special attention to the Maine-to-Virginia corridor; the historical lack of strong hurricanes in the region makes it a favorable site for offshore wind turbines. They found that turbines placed there could satisfy the peak-time power needs of these states for three seasons of the year (summer is the exception).

“We knew there was a lot of wind out there, but this is the first actual quantification of the total resource and the time of day that the resource peaks,” said Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford who directed the research. “This provides practical information to wind farm developers about the best areas to place turbines.”

Mark Z. Jacobson already worked out a framework for powering the entire world from wind, water, and sun alone. The late John Blackburn, Ph.D., showed us how to power North Carolina with sun, wind, and hydro, plus less natural gas than NC uses now. Now Jacobson is working out the details of implementation.

Sinkhole under the shed

The sinkholes are not just in the garage and under the front steps, Michael McCormick walking towards his shed there’s one under Michael McCormick’s tool shed. He already jacked up the shed and put blocks under it after the ground sunk underneath it. With all these sinkholes on his lot (and more in the yard), how are they connected underground? How will they expand?

Green from the Grassroots —Elinor Ostrom

On the day she died, Nobel Prize-winning economist Elinor Ostrom published her last article, in Project Syndicate, 12 June 2012, Green from the Grassroots,

This grassroots diversity in “green policymaking” makes economic sense. “Sustainable cities” attract the creative, educated people who want to live in a pollution-free, modern urban environment that suits their lifestyles. This is where future growth lies. Like upgrading a mobile phone, when people see the benefits, they will discard old models in a flash.

Of course, true sustainability goes further than pollution control. City planners must look beyond municipal limits and analyze flows of resources — energy, food, water, and people — into and out of their cities.

Worldwide, we are seeing a heterogeneous collection of cities interacting in a way that could have far-reaching influence on how Earth's entire life-support system evolves. These cities are learning from one another, building on good ideas and jettisoning poorer ones. Los Angeles took decades to implement pollution controls, but other cities, like Beijing, converted rapidly when they saw the benefits. In the coming decades, we may see a global system of interconnected sustainable cities emerging. If successful, everyone will want to join the club.

And counties, and regions, and watersheds, of course. As Mayor Julian Castro of San Antonio said, there is a "nexus between sustainability and job creation." We don't have to wait for San Antonio or Los Angeles or Beijing or Atlanta to lead the way: we can get on with it right here where we are.

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.

The Emperor’s New Clothes —Michael Noll

The VDT apparently declined to print this LTE submission. I added the links and images. -jsq

When I opened a recent “Sunday Business” section of the Valdosta Daily Times I was expecting to see a thorough discussion of the pros and cons of smart meters. After all, the headline read: “Smart Meters — Fact or Fiction?” What I found, however, was quite different. In case you missed it, here a summary of the highlights:

According to Georgia Power “concerns about smart meters are nothing more than myths.” These concerns range from health risks and increased bills to an invasion of your privacy and house fires started by electrical shorts. Myths or not, the best way to counter customers’ concerns would be to provide studies that, for example, show that smart meters are less dangerous than cellular phones or that electricity bills have not increased as a result of smart meters. However, customers only get assurances which, frankly, do nothing to dispel existing concerns.

Georgia Power also claims that it is using smart meters to be more environmentally

Professor unrepentant in latest fracking payola case

Apparently the natural gas industry pays professors to greenwash their polluting product, like back in the hey-day of radio record companies used to pay disk jockies to play their records. Remember: natural gas from fracking is the main thing Southern Company and Georgia Power are switching to from coal (not that they’re even abandoning coal, just rebranding it as “21st century coal”). That and their nuke boondoggle at Plant Vogtle. All approved by the Georgia Public Service Commission, all of whose members apparently accept massive direct or indirect contributions from the utilities they regulate. Two GA PSC Commissioners slots are up for election right now.

The professor most recently found to be in the pay of a fracking company when he reported on fracking is unrepentant. Terrence Henry wrote for State Impact Texas yesterday, Texas Professor On the Defensive Over Fracking Money

So the questions remaining are: Why didn’t Groat disclose this in the study? And did he fail to tell anyone at the University about it?

The professor would not agree to an interview, but in an email to StateImpact Texas he says the Public Accountability Initiative report is “a mixture of truths, half truths, and unfounded conclusions based [on] incorrect interpretations of information. I don’t want to discuss it.”

The University of Texas requires that financial conflicts of interest be disclosed by employees when it has “potential for directly and significantly affecting the design, conduct, or reporting of … research or is in an entity whose financial interest appears to be affected by that research.”

Dean Sharon Mosher of the Jackson School of Geosciences says that Groat submitted the financial conflict of interest form to her office in previous years, but that he had not done so this year. “I was not aware that he was still a member of the board,” Mosher tells StateImpact Texas. “Had I known he was still a member of the board and being paid, I would have insisted that he disclosed it.”

What report? Follow the links in here. Terrence Henry wrote for State Impact Texas 23 July, Fracking Company Paid Texas Professor Behind Water Contamination Study,

Earlier this year, a study led by Dr. Charles “Chip” Groat for the Energy Institute at the University of Texas at Austin made headlines for saying there was no link between fracking and groundwater contamination. (When we reported on the study in February, we noted that the study also found some serious issues around the safety and regulation of fracking that weren’t getting much press coverage.)

But according to a new report out today by the Public Accountablitiy Initiative (PAI), a nonprofit watchdog group, the conclusions in Groat’s report aren’t as clear cut as initially reported. And Groat himself did not disclose significant financial ties to the fracking industry.

Groat, a former Director of the U.S. Geological Survey and professor at the Jackson School of Geosciences at the University of Texas at Austin, also sits on the board of Plains Exploration and Production Company, a Houston-based company that conducts drilling and fracking in Texas and other parts of the country. According to the new report (and a review of the company’s financial reports by Bloomberg) Groat received more than $400,000 from the drilling company last year alone, more than double his salary at the University. And one of the shales examined in Groat’s fracking study is currently being drilled by the company, the report says.

Since 2007, Groat has received over $1.5 million in cash and stock awards from the company, and he currently holds over $1.6 million in company stock, according to the PAI report. (Update: we clarified with PAI, and that $1.6 million in stock comes from the stock awards over the years. PAI says Groat’s total compensation from the company is close to $2 million.)

And it gets worse from there: rough drafts published, unsubstantiated peer review claims, etc.

This isn’t an isolated case:

This isn’t the first time that academic studies of drilling have been called into question because of industry ties. In an earlier report on a State University of New York at Buffalo study on fracking’s environmental risks, Public Accountability Initiative found that it “suffered a number of critical shortcomings” and the “report’s authors had strong industry ties.”

And in today’s investigation from Bloomberg, they found other instances of industry influence and financial ties at Pennsylvania State University and University of Wyoming.

Do we want to trade air pollution by coal for groundwater pollution by fracking? When we have a better future already at hand through conservation and efficiency along with solar and wind power?
